Passive-Split Heat Exchanger System

Passive-Split Heat Exchangers offer a high degree of installation flexibility since the heat exchanger coils do not have to be side-by-side or in series with the incoming/return airflow.  Since the system is passive there are no pumps required. Performance is comparable to a pumped glycol loop system. An integrated 0-10Vdc proportional ball valve may be placed in the vapor line to modulate the amount of heat transfered.  Systems can be engineered >100 feet apart.

Split-Passive Sytems can be used in lab applications where the Exiting Energy Recovery Coil can be coated to receive common return air flow that collects the buildings air from multiple fume hoods with potential airborne corrosives .

These systems allow for energy recovery year round.
