                                PROXY STATEMENT

     This proxy statement is furnished in connection with the solicitation of
proxies on behalf of the Board of Directors of the Company for use at the annual
meeting of stockholders to be held on June 26, 2001 and at any adjournment
thereof. This Proxy Statement and the form of proxy are first being mailed on
June 1, 2001 to stockholders of the Company. Only stockholders of record at the
close of business on May 21, 2001 will be entitled to notice of and to vote at
the meeting. The Company had outstanding 4,922,364 shares of common stock as of
the close of business on March 31, 2001. There are no other voting securities.
Each stockholder is entitled to one vote per share for the election of
directors, as well as on all other matters. If the accompanying proxy form is
signed and returned, the shares represented thereby will be voted; such shares
will be voted in accordance with the directions on the proxy form or, in the
absence of direction as to any proposal, they will be voted for such proposal;
and it is intended that they will be voted for the nominees named herein, except
to the extent authority to vote is withheld. The stockholder may revoke the
proxy at any time prior to the voting thereof by giving written notice of such
revocation to the Company, by executing and duly delivering a subsequent proxy
or by attending the meeting and voting in person.
   3

     In case any nominee named herein for election as a director is not
available when the election occurs, proxies in the accompanying form may be
voted for a substitute as well as for the other persons named herein. The
Company expects all nominees to be available and knows of no matters to be
brought before the meeting other than those referred to in the accompanying
notice of annual meeting. If, however, any other matters properly come before
the meeting, it is intended that proxies in the accompanying form will be voted
thereon in accordance with the judgment of the persons voting such proxies.

     The presence at the annual meeting, in person or by proxy, of the holders
of a majority of the outstanding shares of common stock of the Company ("Common
Stock") shall constitute a quorum. Abstentions will be treated as shares that
are present and entitled to vote for purposes of determining the presence of a
quorum but as unvoted for purposes of determining the approval of any matter
submitted to the stockholders for a vote. If a broker indicates on the proxy
that it does not have discretionary authority as to certain shares to vote on a
particular matter, those shares will not be considered as present and entitled
to vote with respect to that matter.

     A plurality of the votes of the shares present in person or represented by
proxy at the meeting will be required to elect the directors. The favorable vote
of the majority of the outstanding shares of Common Stock represented at the
meeting will be required for approval of the 2001 Independent Directors Stock
Option Plan and the 2001 Stock Option Exchange Plan.

     In addition to the use of the mails, proxies may be solicited by directors,
officers, or regular employees of the Company in person, by telegraph, by
telephone or by other means. The cost of the proxy solicitation will be paid by
the Company.

     The Company's fiscal year ends January 31. Years described as 2000, 1999,
and 1998 are the fiscal years ended January 31, 2001, 2000 and 1999,
respectively.

indemnification against any and all expenses incurred in connection with, as
well as any and all judgments, fines, and amounts paid in settlement resulting

Independent Directors held four meetings during 2000.

     The Compensation Committee, consisting of Stephen B. Schwartz (Chairman),

                           REPORT OF AUDIT COMMITTEE

     Included in the Company's Annual Report on Form 10-K for the year ended

subsidiaries as of January 31, 2001 and 2000, and the related consolidated
statements of earnings, stockholders' equity and cash flows for each of the
three years ended January 31, 2001. These statements (the "Audited Financial

Deloitte & Touche LLP.

     The Audit Committee reviewed and discussed the Audited Financial Statements
with the Company's management and with the independent auditors prior to

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     David Unger, Chairman of the Board and Chief Executive Officer of the
Company, and Henry M. Mautner, Vice Chairman of the Board of the Company, serve
on the Compensation Committee of the Company's Board of Directors; however, both
Mr. Unger and Mr. Mautner abstain from voting on matters related to their
individual compensation. Prior to the Merger, Messrs. Unger and Mautner also
served on the Board of Directors of Midwesco. Henry M. Mautner is Chairman and
director of New Midwesco. David Unger is Vice President and director of New
Midwesco. Michael D. Bennett, Vice President and Chief Financial Officer of the
Company, is Vice President of New Midwesco. Bradley E. Mautner, Vice President
and director of the Company, is President of New Midwesco. Messrs. Unger,
Bennett and B. Mautner served as directors of Midwesco Services prior to the
Midwesco Services Merger.

     The Company provides certain services and facilities to companies primarily
owned by Messrs. Unger and H. Mautner and those companies provide certain
services to the Company at cost pursuant to a Services Agreement. Any material
change to the terms of the Services Agreement must be approved by a majority of
the directors, including a majority of the independent directors. During 2000,
the Company received $269,000 and paid $350,000 under the Services Agreement.

     On September 20, 2000, the Company purchased a 8.1 acre parcel of land with
a 131,000 square foot building in Niles, Illinois from Messrs. Unger and H.
Mautner. The building had been previously leased by the Company from Messrs.
Unger and H. Mautner and is used by the Company

                                        11
   13

primarily as its headquarters and for its Thermal Care business. The aggregate
purchase price was $4,430,000, which included the assumption of a mortgage note
with a remaining balance of $2,405,000. The property has an appraised value of
$4,600,000. The purchase was approved by the Company's Committee of Independent
Directors. Management of the Company believes that the purchase price was
comparable to what the Company would have been paid in an arm's-length
transaction. The Company paid $359,000 during 2000 to Messrs. Unger and H.
Mautner under the lease agreement in effect prior to the property purchase.

REPORT OF COMPENSATION COMMITTEE OF BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION

     The Company considers the following general guidelines in determining the
compensation of its officers and key employees:

     - Salary set at levels sufficient to attract and retain employees capable
       of contributing materially to the Company's long-term success;

     - Annual incentive compensation related to profit in excess of a threshold
       amount of the Company or of the Company's subsidiary in which the officer
       or key employee is employed;

     - Stock options; and

     - Non-qualified deferred compensation.

     The Company also makes annual contributions to the accounts of eligible
employees in the 401(k) Employee Savings and Protection Plan.

     The Company's 1989 Stock Option Plan, 1993 Stock Option Plan ("1993 Plan")
and the 1994 Stock Option Plan ("1994 Plan") (collectively, the "Plans") were
adopted in order to provide officers and other key employees with long-term
incentives in order to create an interest in the Company parallel to that of the
Company's public stockholders. Option exercise prices will be no less than fair
market value of the Common Stock on the date of grant. Under the Plans, options
may be granted to key employees (including officers, whether or not directors)
of the Company, its subsidiaries, Midwesco, and its affiliates. The options
granted under the Plans may be exercised for periods of up to ten years from the
date of grant. Under the 1993 Plan, 100,000 shares of common stock of the
Company are reserved for issuance upon the exercise of options granted
thereunder. Under the 1994 Plan, 250,000 shares of common stock of the Company
are reserved for issuance upon the exercise of options granted thereunder, which
number shall be increased by the number equal to 2% of the aggregate number of
shares of common stock outstanding as of the last day of the most recently ended
fiscal year of the Company. Provided the Company does not issue any additional
shares of its common stock, the maximum number of shares which may be sold to
all optionees pursuant to the 1994 Plan during the term of the 1994 Plan will be
1,081,709. The Committee believes additional incentive compensation should be
made available to officers and other key employees, which will increase the
effectiveness of the Company's executive compensation program.

     The Committee believes that the combination of salary, incentive
compensation (which varies directly with the Company's operating profitability),
and stock options (the ultimate value of which is determined by future share
price growth), should constitute an executive compensation program which
encourages enhancement of Company profitability and stockholder value. At a
meeting in April 2001, the Committee reviewed the value of the Plans as an
incentive. The Committee concluded that since all outstanding stock options
granted under the Plans had exercise prices substantially in excess of the then
current market price of the Company's stock, the Plans were not providing the
desired incentive to employees. The Committee has recommended that each optionee
who is an employee and each independent director shall have the right to
surrender all outstanding options under the Plans and the 1990 Directors Plan
held by such optionee in exchange for the right to receive a new option for the
same number of shares on December 31, 2001 (or such later date that is
approximately six months and a day after the cancellation is effective) at the
fair market value
                                        12

on the date of the new option grant. The Committee also recommended that any
such cancellation and new grant be subject to stockholder approval. The proposal
to approve the plan to cancel existing stock options and grant new options is
set forth under the caption "The 2001 Stock Option Exchange Plan" herein.

     The compensation of David Unger, Chairman of the Board and Chief Executive
Officer of the Company, reflected in the Summary Compensation Table, was based
on his contribution to the Company. Mr. Unger's annual incentive compensation
increased in 1999 and decreased in 2000 as a result of the yearly changes in the
Company's pretax earnings. Although a member of the Compensation Committee, Mr.
Unger abstains from voting on matters related to his individual compensation.

     Don Gruenberg, Vice President of the Company and President and Chief
Operating Officer of Thermal Care, Inc., receives annual compensation consisting
of a base salary and incentive compensation. Mr. Gruenberg's incentive
compensation is calculated on a basis similar to that of the Company's other
officers. Mr. Gruenberg's incentive compensation increased significantly in 2000
as a result of the application of the then applicable incentive formulas to the
actual operating results.

     Fati A. Elgendy, Vice President of the Company and President of Perma-Pipe,
receives annual compensation consisting of a base salary and incentive
compensation. Mr. Elgendy's incentive compensation is calculated on a basis
similar to that of the Company's other officers. Mr. Elgendy's annual incentive
compensation increased in 1999 and decreased in 2000 as a result of the

                         STOCK PRICE PERFORMANCE GRAPH

     The Stock Price Performance Graph compares the yearly percentage change in
the Company's cumulative total stockholder return on its Common Stock with the
cumulative total returns of the Nasdaq Market Index (the "Nasdaq Index") and the
Russell 2000 Index. The Company has selected the Russell 2000 Index, which is an
index of companies with similar market capitalizations to the Company, as the
most appropriate comparison, because the Company has three distinctly different
businesses and no industry "peer" group is comparable to the Company. The
comparison assumes $100 investments on February 1, 1996 in the Company's common
stock, the Nasdaq Index and the Russell 2000 Index, and further assumes
reinvestment of dividends.

            APPROVAL OF 2001 INDEPENDENT DIRECTORS STOCK OPTION PLAN

     The Board of Directors believes that stock option plans are important in
attracting directors of high caliber and outstanding capabilities. Accordingly,
the Board of Directors on April 18, 2001 adopted a stock option plan designated
as the "2001 Independent Directors Stock Option Plan" (the "2001 Directors
Plan") which is intended to replace the 1990 Directors Plan pursuant to which
authority to grant options terminated in September, 1999. Each director of the
Company who is not an employee of the Company or any subsidiary of the Company
is eligible to participate in the 2001 Directors Plan.

                                        14
   16

     Options are to be granted under the 2001 Directors Plan as follows: (i) an
option to purchase 10,000 shares upon an eligible director's first election as a
director of the Company; (ii) an option to purchase 1,000 shares of the
Company's common stock will be granted automatically to eligible directors upon
each such date as such eligible director is re-elected as a director of the
Company commencing with the annual meeting for the year 2002; (iii) an option to
purchase 1,000 shares of the Company's common stock will be granted to each
eligible director on December 31, 2001 or such later date new options are
granted under the Stock Option Exchange Plan; and (iv) the Board of Directors
shall have the discretion to make additional option grants to eligible directors
from time to time as the Board of Directors deems necessary or desirable. If the
2001 Stock Option Exchange Plan is approved by the Company's stockholders, then
the new options to be granted to non-employee directors under such plan, if any,
will be granted under the 2001 Directors Plan. Authority to grant such options
expires on March 31, 2011. Options granted under the 2001 Directors Plan are not
intended to be "incentive stock options." The aggregate number of shares which
may be sold pursuant to the 2001 Directors Plan may not exceed 100,000.

     Options granted under the 2001 Directors Plan will expire approximately but
not more than ten years from the date of the grant, and the purchase price per
share to be specified in each option will be the fair market value of a share of
the Company's common stock on the date the option is granted. Options granted
under the 2001 Directors Plan are not transferable other than by will or the
laws of descent and distribution. The 2001 Directors Plan permits payment to the
Company upon the exercise of stock options granted under the 2001 Directors Plan
to be made in cash, or in common stock of the Company, or a combination thereof.
Each share of common stock received by the Company in payment of the purchase
price specified in a stock option will be valued at its fair market value on the
date of exercise.

     The exercise of options may be subject to such terms and conditions not
inconsistent with the 2001 Directors Plan as the Company may specify in granting
or amending such options or rights and such terms and conditions may differ from
the terms and conditions described herein. Upon the exercise of any option, the
Company may deliver either treasury shares or authorized but previously unissued
shares. If any option, or any portion of any option, under the 2001 Directors
Plan expires or terminates unexercised, becomes unexercisable or is forfeited or
otherwise terminated, surrendered or cancelled as to any shares, such shares
shall thereafter be available for further grants under the 2001 Directors Plan.

     Options will accrue in four equal annual cumulative installments, with the
first installment accruing approximately one year after the date of grant. All
installments accrue in the event that an optionee dies or becomes permanently
disabled or there is a change in control of the Company. Options may not be
exercised by an optionee after the date he ceases to be a director of the
Company, except that the optionee has three months from such date for any reason
other than death or permanent disability, or the optionee's estate or the
optionee has one year after death or permanent disability to exercise an option,
but in no event may an option be exercised later than its expiration date.

     The Board of Directors may in its discretion prescribe such provisions and
interpretations not inconsistent with the 2001 Directors Plan as it deems
necessary or advisable for carrying out the purposes of the 2001 Directors Plan.
The Board of Directors may amend the 2001 Directors Plan without stockholder
approval, except any amendment that would (i) materially increase the benefits
accruing to participants under the 2001 Directors Plan, (ii) materially increase
the number of shares which may be issued under the 2001 Directors Plan, or (iii)
materially modify the requirements as to eligibility for participation under the
2001 Directors Plan, must be approved by a vote of the stockholders of the
Company.

     At any time when an optionee must pay to the Company an amount required to
be withheld under applicable income tax laws in connection with the exercise of
an option, the optionee may satisfy this obligation by electing (the "Election")
to have the Company withhold shares of common

                                        15
   17

stock having a value equal to the amount required to be withheld. The value of
the shares to be withheld is based on the fair market value of such shares on
the date that the amount of tax to be withheld is determined ("Tax Date"). Each
Election must be made prior to the Tax Date. The Board of Directors may
disapprove of any Election or may suspend or terminate the right to make
Elections. An Election is irrevocable.

     In the event of a stock dividend, stock split, or combination of other
reduction in the number of issued shares of common stock of the Company, under
the 2001 Directors Plan, the Board of Directors must make such adjustments in
the number of unpurchased shares subject to the 2001 Directors Plan, the number
of shares subject to options outstanding in the 2001 Directors Plan and the
exercise price specified in options outstanding under the 2001 Directors Plan as
it determines to be appropriate and equitable. In the event of a merger,
consolidation, reorganization or dissolution of the Company, or the sale or
exchange of substantially all of the Company's assets (i) the rights under
options outstanding under the 2001 Directors Plan will terminate, except to the
extent and subject to such adjustments as may be provided by the Board of
Directors or by the terms of the plan or agreement of merger, consolidation,
reorganization, dissolution or sale or exchange of such assets, and (ii) the
Company must notify the holders of outstanding options of such event at least 30
days prior to the effective date of such event.

     Upon the grant of an option under the 2001 Directors Plan, optionee will
not realize taxable income for federal income tax purposes. Upon the exercise of
an option granted under the 2001 Directors Plan, the optionee will realize
compensation taxable as ordinary income in an amount equal to the excess of the
fair market value of the stock acquired, determined at the time of exercise,
over the option price. The Company will be entitled to a federal income tax
deduction to the extent the optionee realizes compensation taxable as ordinary
income for federal income tax purposes.

     For financial accounting purposes under generally accepted accounting
principles presently in effect, the grant or exercise of stock options under the
2001 Directors Plan does not result in a charge to the Company's net income.

     If the 2001 Directors Plan is not approved by the stockholders, no options
will be granted under the 2001 Directors Plan.

     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR
APPROVAL OF THE 2001 INDEPENDENT DIRECTORS STOCK OPTION PLAN.

                        2001 STOCK OPTION EXCHANGE PLAN

     The Company's Board of Directors, based upon the recommendation of the
Committee of Independent Directors, has determined that it would be in the best
interests of the Company and its stockholders to implement a plan (the "2001
Stock Option Exchange Plan" or the "Exchange Plan") under which the Company will
grant new stock options in exchange for all outstanding stock options issued to
employees, including officers, and directors, pursuant to the Plans and the 1990
Directors Plan.

     Stock options represent an important component of the Company's
compensation program for its employees. Stock options are intended to provide
employees with an incentive to continue in their employment relationship with
MFRI and to align employee financial interests with long-term stockholder value.

     However, as a result of the fluctuations in the market price of MFRI's
common stock during recent years, all of the Company's outstanding stock options
have exercise prices substantially in excess of the current market price of the
Company's common stock. Accordingly, these options are no longer effectively
providing the incentive to employees that they were intended to provide.

                                        16
   18

     The Exchange Plan is intended to realign the exercise price of previously
granted options with the current market price of the Company's common stock and
thereby better enable the Company to motivate and retain its employees and
achieve the Company's business goals.

     Although stockholder approval of the Exchange Plan is not required by law
or any regulations applicable to the Company or the terms of the Company's stock
option plans, the Company has determined not to implement the program unless it
is approved by our stockholders.

     For any future grant awards, employees will be considered to have their
original grant of options and will not receive larger or smaller grants because
of their participation (or non-participation) in the Exchange Plan.

BACKGROUND

     The Company's general policy has been to grant options to employees at the
time of their initial employment and to make annual grants of options to
employees. At the time an option grant is made, the Company specifies the number
of shares of the Company's common stock that can be purchased upon exercise of
the option and the price per share which the employee must pay in order to
exercise the option. Options under the Plans and the 1990 Directors Plan were
granted at not less than fair market value for the number of shares set forth in
the plan.

     As of January 31, 2001, options to purchase an aggregate of 798,950 shares
of common stock were eligible for exchange under the Exchange Plan with exercise
prices ranging from $4.09 to $8.10.

DESCRIPTION OF THE EXCHANGE PLAN

     Grant of New Options.  Under the Exchange Plan, employees of the Company
may elect to exchange some or all of their existing options and to receive a new
option on December 31, 2001 or thereafter on or about the first business day
that is at least six months and one day after the cancellation of the old
options. The exercise price of the new option will be equal to the market price
of common stock as of the grant date of the new option. Participation in the
Exchange Plan is voluntary.

     Numbers of Shares to Be Covered by New Options.  The Exchange Plan provides
that an employee may elect to exchange his or her existing options on a grant by
grant basis. For example, if an employee had two grants of 1,000 shares each,
such employee could elect to participate in the program with respect to one or
both 1,000 share grants, but could not elect to participate with respect to a
fraction of a grant.

     Vesting and Exercisability of New Options.  The Exchange Plan provides
generally that all new options that are granted will vest in four equal annual
installments, regardless of the vesting schedule of the options surrendered or
whether such options were currently exercisable prior to their replacement.

     Eligibility to Participate in the Exchange Plan.  The Exchange Plan is open
to all optionees who are employees, including officers, and directors of the
Company.

     Expiration Date of New Options.  All new options will have a term of ten
years from the date of grant, subject to earlier termination in the event of
termination of employment.

     Implementation of the Exchange Plan.  The Exchange Plan was authorized by
the Board of Directors in April, 2001, subject to receipt of stockholder
approval at the annual meeting. On May 25, 2001, eligible employees and
directors were offered the opportunity to participate in the Program, subject to
stockholder approval of the program, pursuant to an Offer to Exchange
distributed to all eligible employees and included as part of a Schedule TO
filed with the Securities and Exchange Commission. Because each optionee's
decision as to whether or not to participate in the Exchange

                                        17
   19

Plan is completely at the discretion of the optionee, the Company is not able to
predict how many options any particular person or group will elect to exchange.

     If the stockholders approve the Exchange Plan, new options will be issued
in accordance with the program on December 31, 2001 or thereafter on or about
the first business day that is at least six months and one day after the
cancellation of the old options.

     Material Federal Income Tax Consequences.  The exchange should be treated
as a non-taxable exchange and no tax income should be recognized upon the grant
of a new option.

     Information Regarding Eligible Options.  The following table provides
certain information relating to options held by directors, officers and
employees which are eligible for inclusion in the Exchange Plan.
