MFG Part Number DA-075-12-02-00-00

# DA-075-12-02

##  PowerCool Series Thermoelectric Cooler Assembly

 The DA-075-12-02 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 71 Watts when ΔT = 0 and a maximum ΔT of 42 °C at Qc = 0.
