Northvale, NJ (June 21, 2005) — Fred Depuy, President and CEO of AERCO International, Inc. announces the company's membership in GAMA, the Gas Appliance Manufacturers Association. AERCO brings its experience as a pioneer in the high-efficiency, commercial boiler and water heater market to the national trade association representing manufacturers of appliances, components and related products used in space and water heating, commercial food service and power generation.

"I'm delighted to be a member of the GAMA team" said Depuy. The commercial market's demand for high-efficiency products has gone from a niche requirement to a critical need of the market at large. We offer GAMA an unparalleled 17 years of experience delivering products and system design solutions which answer this need. As a technology leader in the high-efficiency market, I believe we can increase GAMA's strength and influence in the legislative, regulatory and standards developing areas."

"I'm also happy that Earl Rightmier, an engineer at AERCO, is serving as vice-chair of the association's Hydronics Institute Technical Committee." This group was involved in developing the new Boiler Testing Standard (BTS2000) which is expected to be referenced by the U.S. Department of Energy when setting minimum efficiency guidelines for commercial boilers. The committee also worked with the Technical Advisory Group for ANSI Standard Z.21.13, a basic standard for safe operation, substantial and durable construction, and performance of gas-fired low pressure steam and hot water boilers. As AERCO's representative to GAMA, Rightmeir will also participate in a special Laboratory Liaison Committee to ensure that independent, third party, certification organizations are consistent in their code interpretation and testing procedures.
