We performed a boiler, pump, and variable frequency drive (VFD) replacement for TCAT in Morristown in conjunction with the Sate of Tennessee. The boiler selected was a 3 million BTU Lochinvar Crest condensing boiler. The boiler was paired with a Bell & Gossett pump and Danfoss VFD. This system has regulated the heating of the building as well as saving the school money on their utility bill.
