Direct-to-Air Thermoelectric Assemblies
The PowerCool Series direct-to-air thermoelectric assembly is a high performance
thermoelectric based heat pump. It is designed to temperature control small chambers
used in medical diagnostics or sample storage compartments in analytical instrumentation.
This unique design offers a high performance hot side heat dissipation mechanism that
convects heat more efficiently than conventional heat exchanger technologies.
The design utilizes custom thermoelectric modules to maximize cooling capacity and
premium grade fans to reduce noise. Moisture resistant insulation is used to keep
condensation from penetrating into the TEM cavity. This unit operates on 48 VDC and is
designed for indoor lab use environment. Custom configurations available upon request.

SERVICE
Units are generally maintenance free, however occasionally it is recommended to clean the heat sinks and fans of debris. This is best done
with compressed air.
