AAT-085-24-22

Overview: Tunnel Series
The AAT-085-24-22 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 unit operates on DC and is designed for an indoor lab use environment. It has a maximum Qc of 78.1 Watts when ΔT = 0 and a maximum ΔT of 30 °C at Qc = 0.
