A line of energy recovery modules for direct- and indirect-fired heating or cooling sections is available. With an air-to-air plate exchanger, Rapid™ energy recovery modules capture heat from the air handler’s exhaust air and transfer it to the incoming air at an efficiency of approximately 60 percent (Air-Conditioning, Heating, and Refrigeration Institute-certified.) According to the manufacturer, the energy savings achieved helps result in a quick return on investment; many paybacks are less than 2 years. Since the module’s plate-style design does not have moving parts, longer equipment life and minimal maintenance can be expected, said the company. Standard available airflows are 2,000 to 60,000 cfm. During summer ventilation or when using a mechanical cooling section or when frost prevention is required, face and bypass dampers may be used to divert outside or return air around the energy recovery module.
