Tunnel Series DAT-040-12-02-00-00
Direct-to-Air Thermoelectric Assembly
The Tunnel Series Direct-to-Air thermoelectric assembly is a
thermoelectric based air conditioner designed to temperature
control small chambers used in analytical and medical
diagnostic instruments. The unique design offers premium
fans pushing air across-high density heat sinks to minimize the
number of air flow paths required to operate. The design
utilizes custom thermoelectric modules to maximize cooling
capacity with a high coefficient of performance. Moisture
resistant insulation is used to keep condensation from
penetrating the TEM cavity. The units operate on DC and are
designed for an indoor lab use environment.
