MHG Heiztechnik GmbH hereby certifies the following for the heat pumps listed below:
The heat pumps are equipped with different safety circuit devices for pressure limitation in the refrigerant cycle
in compliance with DIN 32733.
The high pressure guard safety limit switch shuts off the condenser automatically if the pressure of the medium
in the refrigerant cycle exceeds 28 bar.
The refrigerants R407C and the cooling equipment machine oil (diester oil) are environmentally compatible.
According to the EU safety data sheet, the refrigerant R407C consists of 23% difluoromethane (HFKW 32),
25% pentafluoroethane (HFKW 125) and 52% tetrafluoroethane (HFKW 125).
The RVS 61 heat pump controller used by MHG in the system is equipped with sensors for the recording and
control of the source outlet temperature and the heating flow temperature. If temperatures reach levels endan-
gering the system, the heat pump is shut off automatically.
