PowerCool Series A DA-280-48-02-00-00 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.
