MRCOOL Closed Loop Installation Kit 6 Ton with Straight Manifold GCIK-CL6T-SM

The MRCOOL Closed Loop Installation Kit 6 Ton with Straight Manifold (model GCIK‑CL6T‑SM) is a comprehensive geothermal ground‑loop accessory package designed for use with 6 ton GeoCool Inverter Series heat pump systems. This all‑in‑one kit supplies the major components needed to build a closed‑loop geothermal heat exchange field, enabling efficient ground‑source heating and cooling performance throughout the year. It provides the essential infrastructure required for a professional geothermal loop installation in larger residential or light commercial applications.

Included in the kit are the main loop components sized specifically for a 6 ton system, such as multiple rolls of 3/4″ high‑density polyethylene (HDPE) loop pipe, a straight‑manifold insulated header, and a Geo‑Pulse non‑pressurized geothermal flow center with dual pumps. Also provided is a geothermal hose kit with elbow adapters to streamline connections between the loop field and the heat pump, along with propeller glycol heat transfer fluid to help protect against freezing and improve thermal exchange efficiency.

All components are constructed with corrosion‑resistant materials intended for long‑term buried use, helping ensure durability and consistent performance in subterranean conditions. The straight manifold design supports a linear, direct routing layout that can simplify installation in spaces where a simple, level loop configuration is preferred.

Optimized for larger GeoCool installations, this bundled kit brings together all of the major loop parts needed for a closed‑loop geothermal setup. Its comprehensive configuration helps reduce the need to source individual components separately, making it a practical and reliable foundation for efficient ground‑source HVAC performance.
