The MRCOOL Closed Loop Installation Kit 5 Ton with Straight Manifold (model GCIK‑CL5T‑SM) is a complete geothermal ground‑loop accessory kit engineered to support a 5‑ton geothermal heat pump system. It bundles all the essential parts needed to establish a closed‑loop geothermal field, providing a streamlined foundation for efficient ground‑source heating and cooling performance. This kit is well‑suited for larger residential systems or light commercial geothermal installations.
This installation kit includes multiple rolls of 3/4″ high‑density polyethylene (HDPE) loop pipe sized for a 5‑ton application, along with a 5‑circuit insulated header in a straight configuration that supports organized and direct underground routing. A Geo‑Pulse non‑pressurized flow center with dual pumps delivers consistent fluid circulation throughout the loop, while a geothermal hose kit with 90° elbow adapters simplifies the connections between the ground loop and the heat pump.
To help protect the system and enhance thermal transfer, the kit also includes 5 gallons of ProTek PG Plus propylene glycol heat transfer fluid, which assists in freeze protection and efficient energy exchange in the ground loop. Each component is made with corrosion‑resistant materials, making the setup durable and long‑lasting once installed below grade.
The straight manifold design is ideal for flat or level terrain installations, providing a straightforward layout with fewer bends and fittings, which can simplify the installation process for HVAC professionals. Designed for use with MRCOOL GeoCool geothermal systems, this bundled kit brings together all of the major loop components to support dependable and efficient closed‑loop performance.
