The GeoCal™ pre-assembled manifold for ground-source geothermal loops offers an alternative method of piping parallel earth loops, bringing all circuits to a common manifold station without labor-intensive fusion welding. GeoCal™ manifolds provide significant installation, commissioning, and operational advantages. With optional ¾” or 1” QuickSetter™ balancing valves with flowmeters and shutoff ball valves, GeoCal™  allows easy individual circuit isolation and balancing leading to lower pumping costs and greater system efficiency. Shutoff ball valves installed on the return manifold simplifies individual circuit filling and purging while minimizing purge pump size. GeoGrip™ couplings are used for connecting to polyethylene piping, either directly to the manifold or to the balancing valves and shutoff valves, making the ground earthloop installation completely free of fusion joints.
