The earth taps are approximately 65 feet long pieces of tubing inserted into the ground in holes drilled with a rock or mud rotary drill. The holes are drilled at an angle and fan outward from two central manifolds buried several feet below the ground surface. The use of heavy walled copper tubing ensures excellent heat transfer characteristics. Lines run from the manifolds to the compressor unit. This earth tap system requires only a single coolant loop and avoids the problems associated with intermediate fluids and additional pumping systems. The system also requires neither ground water sources nor costly deep wells for operation. It can be sited in a compact area with relative ease.

The compressor unit is responsible for controlling the flow of refrigerant through the earth taps. This central unit can be located either inside or outside a home or building and has dimensions of 27"x20"x19". For applications requiring more than five tons of cooling, multiple units may be required.

The air handler, connected to the compressor unit, is where the heat is transferred from the unit and circulated into the rest of the building. In heating mode, the typical air supply temperature is 100 degrees Fahrenheit, providing comfortable warmth for any application. While ECR Industries does not provide the actual air handler to work with our systems, we work closely with HVAC technicians to ensure that a system is constructed to provide our customers with efficient and comfortable heating and cooling.
