Designed for refrigeration of medical chambers and analytical storage compartments, the DA-280 TEA is an alternative to compressor systems. Refrigeration is vital in medical storage chambers as temperature fluctuations can affect the life of a reagent, meaning they may only last a couple of hours at room temperature and this can influence the final test result.

With over 280W of cooling power, the DA-280 offers reliable operation with low maintenance costs and is environmentally friendly. Additional design factors include temperature stability and enhanced resistance to moisture intrusion, which can be a problem for applications that operate below dew point. 

“This expands the PowerCool Series product offering with a much higher cooling capacity system,” said 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.”

The DA-280 Direct-to-Air TEA operates on 24 VDC and uses custom thermoelectric (Peltier) modules to maximize cooling capacity and optimize efficiency. The unit uses premium grade fans with low noise and has superior barrier protection to keep moisture from penetrating inside the unit. The hot side heat exchanger has been optimized to dissipate heat into the environment at a rapid rate. Custom configurations are available.
