TH-500VX VacuFlo Water Heater

Steam Fired Water Heater

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.

Standard Features & Benefits:

  • 10% Energy savings over conventional type steam fired hot water heaters due to the use of vacuum steam with high latent heat
  • Heater accepts high pressure steam (150 psi) to the control valve inlet eliminating the need for steam pressure reducing stations
  • Condensate is pumped directly into the return system eliminating wasted flash steam to atmosphere and vent pipes to the roof
  • Digital control interfaces with building EMS
  • High temperature safety shutdown system
  • Complete guaranteed and tested system
  • Complete welded vacuum side piping
  • 10 Year tube bundle and shell warranty

TH-500ZX Zero Flash Water Heater

Zero Flash Water Heater

Save Energy | Save Installation Cost | Save on Retrofits

The TH-500ZX fully condenses the latent heat BTUs and discharges condensate below atmospheric temperature eliminating flash steam. No additional flash tanks are required and condensate can be discharged directly to an electric or pressure powered condensate return pump system. Up to 5% of the steam can be saved!
