Iron smelters have high voltage services coming into their facilities. With transformers these are reduced to lower usable voltages. This particular customer had a transformer installed in an area were the air was stagnant. Without adequate air circulation the transformers overheated and eventually failed shutting down sections of the plant.
EXAIR suggested they install a model 110054 Super Air Knife positioned over the cooling fins. The ability of the air knife to deliver huge volumes of air, more than enough air showered the cooling fins to keep the transformers cool.
Installation was simple and with no moving parts, there was no maintenance. The customer was more than satisfied with the performance and duly impressed as to the ease of installation.
