Direct to air thermoelectric assembly targets critical refrigeration
Laird Thermal Systems has developed a large capacity direct-to-air thermoelectric assembly (TEA) that it says offers greater cooling capacity than traditional thermoelectric based systems.
Designed for refrigeration of medical chambers and analytical storage compartments, the DA-280 TEA is an alternate to smaller compressor based systems.
Refrigeration is vital in medical storage chambers. Temperature fluctuations can affect the life of a reagent, as they may only last a couple of hours at room temperature and this can influence the final test result.
Offering more than 280W of cooling power, the compact DA-280’s additional design factors include, temperature stability, and enhanced resistance to moisture intrusion, which can be a problem for applications that operate below dew point.
The DA-280 Direct-to-Air TEA operates on 24 VDC and uses custom thermoelectric (Peltier) modules to maximise cooling capacity and optimise efficiency.
The unit uses premium grade fans with low noise and superior barrier protection helps keep moisture from penetrating inside the unit. The hot side heat exchanger has been optimised to dissipate heat into the environment at a rapid rate
“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, are 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,” he said.
Custom configurations are available upon request.
Laird Thermal Systems designs, develops and manufactures thermal management solutions for applications across medical, industrial and telecommunications markets.
Its portfolio ranges from active thermoelectric modules (TEMs) and thermoelectric assemblies (TEAs) to temperature controllers and liquid cooling systems.
By offering a range of design, prototyping and in-house testing capabilities, Laird Thermal works closely with customers across the product development lifecycle to reduce risk and accelerate time-to-market.
