Outdoor Cooler Series AA-230-24-D44
MFG Part Number: 43700000213000
Outdoor Cooler Series Thermoelectric Cooler Assembly
The AA-230-24-D44 is an Air-to-Air thermoelectric cooler assembly that uses impingement flow to transfer heat. It offers dependable compact performance by cooling objects via convection. Heat is absorbed and dissipated through 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 model 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.
Features
  • Wide operating temperature range from -40°C to +55°C
  • Telcordia GR-487-CORE tested and verified by customers when integrated in telecom outdoor enclosures.
  • Environmentally friendly solid-state operation
  • No compressor or CFC refrigerants
  • Optional bi-polar thermostatic control
