PLATE EXCHANGER | WC_AN

Recovery Plate

D-54 www.carnes.com

The WC_AN SERIES is a heat recovery ventilator with a choice of polypropylene, aluminum or enthalpy core for indoor installation. Four standard models are available to meet your needs from 400 CFM to 5500 CFM. All incorporate flat plate heat exchangers designed to transfer energy between the exhaust and the fresh air streams.

The aluminum plate exchanger is made from embossed aluminum plates increasing air turbulence inside the heat exchanger for maximum sensible heat transfer, ideal for applications that must meet the NFPA-90A requirement.

The polypropylene is the most cost effective way to recover sensible heat in a corrosive environment.

The enthalpy plate exchanger is the alternative solution to total energy recovery with less maintenance cost from a stationary core.
