DA-045-12-02

Overview: PowerCool Series
The DA-045-12-02 is a Direct-to-Air Thermoelectric Assembly (TEA) 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 42.2 Watts when ΔT = 0 and a maximum ΔT of 35 °C at Qc = 0.
