Outdoor Thermoelectric Cooler Assembly
Page 1 of 4
The AA Outdoor Cooler Series is an Air-to-Air thermoelectric
assembly (TEA) that uses impingement flow to transfer heat. It
offers dependable, compact performance by cooling objects via
convection. Heat is absorbed and dissipated thru high density heat
exchangers equipped with air ducted shrouds and brand name fans.
The heat pumping action occurs from custom designed
thermoelectric modules that achieve a high coefficient of
performance (COP) to minimize power consumption.
This product series has been designed to pass rigorous Telcordia
test requirements conducted by our customers, such as earthquake
resistance, salt fog, wind-driven
rain, high temperature exposure
and dust contaminants. This is due to the selection of world-class
components such as brand fans with the highest degree of
environmental protection and lifetime guaranteed waterproof
connectors, heavy-duty
anodization on the high-density
heat
sinks, overheat protection, and double environmental seals for the
thermoelectric modules.
