Change
  • Increased efficiency of flue gas heat exchangers
  • Fewer pump circuits
  • Constant boiler water level
  • Minimum flow rate for cooling the feed pump is assured

Further information

Where no speed-controlled feed pump is available, continuous regulation with the RM feed water regulation module is a suitable alternative for all boilers fitted with modulating burners and flue gas heat exchangers. This module slows down the flow through the flue gas heat exchanger for optimal heat recovery from the boiler waste gases. At the same time, the feed water regulation module ensures that the minimum quantity required for feed pump cooling is always present.

The feed water regulation module for infinitely variable control consists of a feed water control valve, discharge device, dirt retention device and two shut-off valves as well as a bypass device.
