Liquid ground-coupled heat exchanger ED-KZ-R

The ground liquid exchanger uses a relatively constant soil temperature at a non-freezing depth (approx. 1.2 to 2 m) of approx. +4 to +8 °C in winter and a temperature of approx. +10 to +14 °C in summer. With increasing depth, the ground temperature increases and approaches a constant value throughout the year.

It is made of REVEL-PEX system cross-linked polyethylene pipe of 16 x 1.8 mm with a PEX connection pipe of 23 x 2.5 mm and a fitting for connecting the hydraulic module. The length of the ED-KZ-RH pipe is optional according to the customer's order.

To determine the pressure losses when antifreeze flows through the ED-KZ-R ground heat exchanger, the selected lengths of the inlets (inlet and return branches of the exchanger) are pressure limiting.

Assembly components:
1. RL 446 E (23 × 2.5)
2. RL 59 - 7× (16 × 1.8; pipe spacing 150 mm)
3. RL 424 - 9×
