Thermoelectric assemblies offer both cooling and heating capabilities to maintain the control temperature of the storage chamber between 40 and 104°F (4 and 40°C) in ambient temperatures of 73 to 86°F (23 to 30°C). They offer condensation protection for applications that go below dewpoint. The company’s assemblies can operate on DC power (12, 24 and 48 V), with a heat load requirement ranging from 25 to 100 W. With a maximum cooling capacity up to 106 W, Tunnel Series is offered in air-to-air and direct-to-air configurations. PowerCool Series is designed for larger sample storage compartments with a higher heat load requirement. It has a maximum cooling capacity of 200 W.
