The steel company from Maryland had some enclosures with 4 drives each on some cranes. The high temperature in the steel mill was causing excessive shutdowns. Leaving the enclosure open in this sort of environment just wouldn’t do. Nor would conventional air conditioners survive the shake rattle and bake of the electrical enclosures on these FHP-1501XE 250VDC overhead cranes. On top of all that the only power they had was a widely varying 250 VDC. Which we found out later had some very nasty spikes which caused everyone a few headaches. But the headaches were cured and the customized FHP-1501XE solid state air conditioners continue to run.
How could the company afford custom units? With a streamlined approach where design engineers and the end users actually communicate on a frequent basis with known goals, expectations and commitment from each end. TECA loves happy customers.
