Ensure maximum system performance and reliability of closed-loop solar systems with a Solar-Divicon pumping station from Viessmann. Choose from a full range of pre-assembled and pre-wired stations to meet the needs of a variety of solar applications. The new Solar-Divicon-HX pumping and heat transfer station incorporates a large, double-wall stainless steel heat exchanger for heat transfer to any standard domestic hot water (DHW) storage tank, three-speed solar loop and DHW pumps, as well as a solar controller. Connect it to a DHW storage tank with upper electric element to create a “one-tank” solar system. The Solar-Divicon-HX is available in two sizes.
