Tunnel Series Thermoelectric Assembly The Tunnel Series 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 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.

INSTALLATION INSTRUCTIONS

Mount with “hot side” external to chamber wall. Cutout should be approximately 99 x 67 mm. Unit should be fastened as shown in diagram with gasket material sealing around cutout. For operation below dew point, recommend to position unit in vertical direction with wires
facing down to allow for condensation to run off of unit. Drip tray may be required to collect moisture from surfaces at temperatures below dew point. TE should not be used as part of the structure and is recommended to be protected from external forces. The input power to TEA should be protected with fuse.
