PowerCool Series Thermoelectric Cooler Assembly
The DA-044-12-02 is a Direct-to-Air Thermoelectric Cooler Assembly that uses impingement flow to transfer heat. It offers dependable, compact performance by cooling objects via conduction. Heat is absorbed through a cold plate and dissipated thru a high density heat exchanger equipped with an air ducted shroud and brand name fan. It has a maximum Qc of 42 Watts when ΔT = 0 and a maximum ΔT of 41 °C at Qc = 0.

You can interact with the Performance Curves below to estimate the cooling performance by entering the thermal and electrical operating conditions for your application.

Notes
1For indoor use only
2Units are generally maintenance free, however occasionally it is recommended to clean the heat sinks and fans of debris. This is best done with compressed air.
