Escher designs and manufactures recuperative heat exchangers and gas stream coolers for use in iron melting cupolas, glass melting, and other high energy use applications. Escher heat exchange equipment has been in use since 1956 and has earned a worldwide reputation for quality. Their recuperators capture energy normally lost to the atmosphere and recirculate it back into the process. This recapture of energy can generate significant fuel savings. Escher gas steam coolers lower temperatures allowing more economical downstream ductwork and more efficient dry style dust collectors. Escher gas stream coolers can also supply waste heat to plant processes and building heating.
