      This statement constitutes Amendment No. 2 to the Schedule 13D filed by the reporting person on February 10, 2000, as corrected and superseded by the Amendment No. 1 filed on even date with this Amendment No. 2.

Item 2. Identity and Background.

      Armstrong International, Inc. ("Armstrong") is a corporation incorporated under the laws of the State of Michigan. Armstrong's principal business is the manufacture and distribution of equipment for industrial and commercial steam systems. Armstrong's principal manufacturing facility is located at 816 Maple Street, Three Rivers, Michigan 49093. Armstrong's principal office is located at 2081 East Ocean Boulevard, Stuart, Florida 34996. During the past five (5) years, Armstrong has not been convicted in a criminal proceeding and is not and has not been a party to any civil proceeding of a judicial or administrative body resulting in any judgment, decree, or final order against Armstrong enjoining future violations of, prohibiting, or mandating activities subject to federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

      Armstrong purchased 3,000,000 shares of Series B Preferred Stock of the Issuer pursuant to a Series B Preferred Stock Purchase Agreement dated June 28, 2001. The Series B Preferred shares were purchased in consideration for Armstrong's guaranty of an extension of credit to an affiliate of the Issuer, Armstrong's extension of a working capital credit facility to the Issuer, and Armstrong's cancellation of a certain debt owed to it by the Issuer. Each share of Series B Preferred Stock is convertible into one share of Common Stock of the Issuer, which conversion ratio is subject to change pursuant to certain anti-dilutive rights as set forth in the Issuer's Articles of Incorporation.

      Armstrong has purchased the securities for investment purposes. Armstrong may acquire additional shares of Common Stock of the Issuer or securities convertible into Common Stock of the Issuer, or may dispose of the same, through market transactions or otherwise.

      Armstrong beneficially owns 4,931,114 shares of Common Stock of the Issuer pursuant to its ownership of 1,542,793 shares of Series A Preferred Stock of the Issuer and 3,000,000 shares of Series B Preferred Stock of the Issuer. Both the Series A Preferred Stock and the Series B Preferred Stock are convertible into shares of Common Stock of the Issuer as described in Amendment No. 1 to Schedule 13D (referenced above) and Item 3 above. This statement does not reflect any change in the conversion ratio of the Series A Preferred Stock owned by the reporting person as a result of the anti-dilutive rights of such shares. Armstrong's beneficial ownership represents approximately 33.6% of the issued and outstanding shares of the Issuer's Common Stock. Armstrong has sole power to vote and dispose of such stock.
