Danfoss EvoFlat is a substation designed to connect your house installation to a frost-free room where the temperature does not exceed 50 °C and the humidity does not exceed 80%. It is suitable for various energy sources, such as district heating, central boiler (gas, oil, biomass, etc.), solar, heat pump, or a combination of them. The EvoFlat is equipped with safety valves to prevent accidents and injuries. Do not cover or wall up the substation or in any other way block the entrance to the station.

Danfoss EvoFlat is a substation designed to connect your house installation to a frost-free room where the temperature does not exceed 50 °C and the humidity does not exceed 80%. It is suitable for various energy sources, such as district heating, central boiler (gas, oil, biomass, etc.), solar, heat pump, or a combination of them. The EvoFlat is equipped with safety valves to prevent accidents and injuries. Do not cover or wall up the substation or in any other way block the entrance to the station.
