DA Tunnel Series, DA-039-12-02

Thermoelectric Assembly

Tunnel SerieS DirecT-To-Air ThermoelecTric ASSembly

The DA Tunnel Series is a Direct-to-Air thermoelectric assembly (TEA) that minimizes the

number of airflow paths required to operate. It offers dependable, compact performance

by cooling objects via conduction. Heat is absorbed and dissipated through a high density

heat exchanger equipped with an air ducted shroud and a brand name fan. The thermoelectric

modules are custom designed to achieve a high coefficient of performance (COP) to

minimize power consumption. Custom configurations are available, however, MOQ applies.
