The Thermaflo TH500VX Vacuflo Steam Fired Water Heater’s unique operating design accepts high pressure steam up to 130 psig and controls the exchanger pressure in a constant vacuum while controlling outlet hot water simultaneously. Vacuum steam contains more “Latent” heat BTUs than positive pressure steam saving energy. The TH500VX design eliminates steam pressure reducing stations, electric condensate pumps, flash tanks saving thousands on installation cost and long term maintenance. The TH500VX Electronic Controller interfaces with BACNET, Modbus, Lonworks, and many other BMS Products.
