Geo-Booster Active Loop Pressurization System

Adding to cart… The item has been added

Geo-Booster Active Loop Pressurization System.  The Geo-Booster is an active loop pressurization system that maintains a minimum loop pressure of 25 psig[172 kPa], and eliminates issues associated with low pressure in geothermal ground loops.

  • The Geo-Booster includes a pump with a built-in pressure switch, factory set at 25 psig [172 kPa], +/- 3 psig [21 kPa], and a check valve to prevent back-flow into the reservoir.
  • Switch ON setting is 25 psig [172 kPa]; OFF setting is 35 psig [241 kPa]; ON setting is adjustable.
  • The sealing cap ensures a closed system, prevents loop fluid evaporation, and provides vacuum relief allowing the fluid to be pumped from the reservoir.
