Compact thermoelectric assembly expands cooling capacity of product family

Laird Thermal Systems has produced a large capacity Direct-to-Air Thermoelectric Assembly (TEA) that allows greater cooling capacity than conventional thermoelectric based systems. Created for refrigeration of medical chambers and analytical storage compartments, the DA-280 TEA is an alternate to smaller compressor based systems. Offering more than 280W of cooling power, the compact device provides reliable operation with low maintenance costs and is environmentally friendly. Further design factors cover temperature stability and enhanced resistance to moisture intrusion, which can be an issue for applications that operate below dew point. "This expands the PowerCool Series product offering with a much higher cooling capacity system," says Andrew Dereka, product director at Laird Thermal Systems. "New environmental regulations, particularly in Europe is driving interest from leading medical device OEMs to consider thermoelectric based cooling systems as an alternate substitute to compressor-based systems. The problem with new compressor based systems is that they use natural refrigerants, which can have flammability issues during transport."
