BAFA funding opportunity as part of heating system optimisation through hydraulic balancing and installation of separate control technology

rendeMIX multi-port mixing manifold with 3/2-way tangential mixing valve DN25×G1½(a) MsGuss (adapter red), plug and cover Ms58

For highly efficient utilisation of the return flow of an unmixed high-temperature circuit in a mixed low-temperature circuit by means of highly efficient operation of a system separation via flow control at a condensing boiler, a stratified storage tank or a heat transfer station.

Actuator EMS 240, 230V~ 50Hz 3.5VA 3-point signal, 5Nm (240h), 240°, 93s

Dual circuit manifold assembly with 2 connections to the heat source and 4 connections to the heat sinks, CuØ35×1, DN32×G1½(a) flat, pipe spacing 100mm.

3 integrated gravity brakes/backflow preventer, Dp10mbar

Direct heating circuit (HT): Kvs = 11.9 - V'max[100mbar] = 3.8m³/h - Q'max[20K] = 88kW - Mixed circuit (LT) with ST DN25s: Kvs = 7.2 - V'max[100mbar] = 2.3m³/h - Q'max[10K] = 27kW - Leakage rate < 0,1%

6 Thermometers 0-120°C, Ø63mm, soldering sleeves Ms58

6 ball valve screw connections, DN25s passage, PN20, G1½(i)×Rp1 flat-sealing, stuffing box, spindle with aluminium T-handle

Insulating moulded tray EPP 40g/l, black, 450×450mm, quick assembly kit

With pump flange G1½(i) for pump DN25 at the mixing circuit flow (5)

Assembly includes TWO pump balancers - PAS L180 - with G1½(a)×G1½(i) fittings for balancing a pump DN25, length 180mm, insulated (part no.: 001 338).

Assembly does not contain a pump

Model DN 25 - strong version, PN 10bar, Tmax 120°C

ATTENTION: CANNOT BE USED WITHOUT SYSTEM SEPARATION!
