Angelery Engineering Research Company (AERCO) is a leading supplier of boilers and water heating products, and the originator of semi-instantaneous water heating.
AERCO was founded in 1949 to design an indirect fired water heater that heated water on demand without storage and at a controlled temperature. This innovation predicted the future of water heaters. With continued improvements on this design, our engineering people have been able to maximize the recovery of latent heat energy and accurately predict the temperature of the sub-cooled condensate.

Since 1978, Cain Industries has dedicated itself to producting exclusively, combustion exhaust heat transfer products. Our successful experience with lowering fuel costs and reducing pollution makes us the first choice for both the retrofit and OEM client.

Manufacturer of blowdown separators, blowdown tanks, and blowdown heat recovery systems for removing water from steam and other vapors, safely handling blowdown and controlling thermal pollution. Heat recovery systems for small to large boilers can provide up to 90% heat recovery.

Energy Recovery International is located in Lincoln, Nebraska where for over 25 years we have been the market leader for Heat Recovery Steam Generators in the 1-15MW turbine market. With over 450 units sold ERI has peerless experience in the packaged HRSG market.
