netec brine-air heat exchangers are especially designed air heating and cooling coils. They can be used in winter to preheat cold outside air with gound warmed brine as well as to cool down in summer hot outside air. There are produced three series:
Series CWK-F iso
with a heat-insulating EPP-housing and with large air filter integrated, suitable for single- to four-family houses and for air quantities of 100 to 350 cbm/h . Air filter with double layer (G4 + F7), large surface (2,9 m²) and small air pressure drop. Tubular air pipe connections 160mm and 180 mm, expandible up to 250 mm.
This model developed by Netec in 2004 has not been manufactured by Netec since the end of 2022. The production was handed over to the construction information center of the company SchwörerHaus KG. The CWK 300 will probably be available from there from autumn 2023.
