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.
