Laird Thermal Systems (Morrisville, N.C.) has launched a large capacity, direct-to-air thermoelectric assembly (TEA) that is designed for refrigeration of medical chambers and analytical storage compartments.
The new DA-280 TEA is an alternative smaller compression-based systems and has a greater cooling capacity than traditional thermoelectric-based systems.
“This expands the PowerCool Series product offering with a much higher cooling capacity system,” Andrew Derek, product director at Laird Thermal Systems. “New environmental regulations, particularly in Europe, is driving interest from leading medical device OEM to consider thermoelectric based cooling systems as an alternate substitute to compressor based systems. The problem with new compressor based system is that they use natural refrigerants, which can have flammability issues during transport.”
Laird’s new DA-280 TEA system runs on 24 VDC and uses custom thermoelectric modules to optimize efficiency, according to the company. It also uses grade fans that have low noise and barrier protection that prevents moisture from getting inside the unit. The hot side heat exchanger has also been designed to dissipate heat into the environment at a fast rate.
