Geo-Flo manufactures the industry’s only all HPDE hydraulic separator which allows the elimination of another carbon steel component in the geothermal system thereby reducing the possibility of system corrosion. The GHS Geothermal Hydraulic Separator is insulated with CFC-free, polyurethane foam insulation, and is housed in powder-coated steel cabinet. The lightweight design is intended to be wall-mounted. The GHS comes standard with a blow-down valve at the bottom, and an automatic air vent and expansion tank connection port at the top.
Cabinet/Insulation:
Power coated steel; CFC-free, polyurethane foam insulation
Tank:
High density polyethylene
Automatic Air Vent:
Brass body and cover, air vent with silicone rubber seal, polyethylene temperature resistant float. Can be disassembled for inspection and cleaning.
Ball Valves
(3) 1/2“ FPT full port brass, one for connection to expansion tank, one for connection to automatic air vent, and one for use as a blow-down valve.
Application:
The Geo-Flo GHS creates a low pressure loss zone, where two independent primary and secondary circuits may be connected. The flow in one circuit does not affect the flow in the other circuit. The pressure drop of the ground loop (primary circuit) may be considered separately from the pressure drop of the inside piping and heat pump heat exchangers (secondary circuit) resulting in smaller pump sizing. Also, a hydraulic separator is useful in load sharing with buildings that have simultaneous heating and cooling requirements. In these applications, one heat pump maybe in heating while another is in cooling transferring BTUs to each unit without using the ground loop heat exchanger and pump. Additional benefits of a hydraulic separator include air and dirt separation. The low velocity zone (less than 2 fps) allows dirt/debris to fall to the bottom of the tank, where it can be removed at the blow-down valve. Likewise, any air that may still be in the system collects at the top of the tank, where it is eliminated via the automatic air vent.
