Danfoss Termix VX-WP Operating instructions

Brand: Danfoss

Model: Termix VX-WP

Type: Operating instructions

Danfoss Termix VX-WP is a complete solution for space heating and domestic hot water with optimal safety, efficient energy transfer, service - friendly construction and a compact design. It is designed for pressure levels up to PN 16 and high supply temperatures with welded pipes on the primary side. The heating circuit consists of a stainless steel plate heat exchanger, safety valve, manometer, thermometers, ball valves, drain valve and circulation pump. The substation is also equipped with a thermostat with safety monitor, which typically is a requirement in heavyduty systems.
