The Flow Master feeds the heat from the XRGI® system and from the storage tank into the consumer circuit. In the short term, this
allows significantly higher heating capacity on the consumer side than with the installed XRGI® heating line. With this, heat demand
peaks can be handled by the XRGI® system, thus extending its production time and increasing heating capacity.
Four models are currently available that can operate at a ΔT of 20 K with a heat output of 50, 150, 250 or 350 kW. The desired flow
temperatures (up to a maximum of 79.9 °C) are constantly available. The injectable heat output is adjusted automatically depending
on the return temperature from the property‘s network. The decision about which Flow Master to be used with Flow Master Control
is determined according to the building conditions and the consumption habits.
When using a Flow Master with a Flow Master Control, the instructions on the temperature sensors, the injection line and the sizing
of the heating pipes are to be complied with to ensure correct operation.
