Outdoor Thermoelectric Cooler Assemblies
Thermoelectric Cooling Units for outdoor enclosures and kiosks
The 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. The AA-250 has 26% higher cooling capacity and a 21% boost
in efficiency over standard models with same geometric configurations. Heat is absorbed
and dissipated thru custom designed heat exchangers with high aspect ratio, air ducted
shrouds and high performance 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.
