Where Are All the Cold Plates?

Cooling micro-organisms in a lab:

Recently, a prestigious U.S. university’s research lab contacted TECA. The team needed to cool a 340-well micro plate. Their vendors had many hot plates to offer, but no one seemed to offer a like product for cooling. The lab team was happy to discover TECA products online and the AHP-301CPV proved to be the right fit.

The lab’s 340-well plate is filled with a solution housing micro-organisms. To get the organisms to migrate to the bottom of the wells, the lab needed controlled cooling to 0degC. However, there is a limited temperature range in which the organisms do not degrade so precise control was paramount.

Steel Mill Enclosure Cooling:

A major steel company has multiple equipment enclosures, housing 4 variable frequency drives (VFD) each, to control their industrial cranes. The high temperature in the steel mill was causing excessive shutdowns. Compressor-based air conditioners could not survive the electrical enclosures’ harsh ambient environment on the overhead cranes. The only input power available was a widely varying 250 VDC, which complicated things. TECA successfully and affordably customized a flush-mounted (external to enclosure) thermoelectric air conditioner to meet the customer’s needs.

Satellite Communication – Long Service Life:

A testament to TECA quality and reliability, this image shows a 130 foot radio telescope at a research observatory. The red arrow indicates the location of the the TECA air conditioner. TECA’s AHP-1200 is installed there to control the temperature of a 2′ x 2′ x 4′ insulated electronics box . The AHP-1200 runs continuously, 24/7, to control the internal temperature to about +25C. The ambient temperatures range between -10C to +40C.
