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 green) and 3-way mixing valve DN32×G1½(a) Ms58, plug and cover Ms58

For the highly efficient use of the return flow of an unmixed high-temperature circuit (charging circuit) controlled via a changeover valve in a mixed low-temperature circuit (mixing circuit) by means of highly efficient operation of a system separation via flow control on a condensing boiler with minimum circulation

Charging circuit: EMS 90-2P actuator, 230V~ 50Hz 2.3VA 2-point signal, 6Nm (240h), 90°, 60s, right-hand closing, grey adapter. Mixing circuit: EMS 240 actuator, 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.

2 integrated gravity brakes/backflow preventer, Dp10mbar

Charging circuit (HT): Kvs = 12.5 - V'max[100mbar] = 4m³/h - Q'max[20K] = 93kW - Leakage rate < 0.1% - Mixing circuit (NT) with ST DN25: Kvs = 5.7 • V'max[100mbar] = 1.8m³/h • Q'max[10K] = 21kW • Leakage rate < 0,1%

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

6 ball valve unions, DN25 passage, PN32, G1½(i)×Rp1 flat-sealing, stuffing box, sealing hole, spindle with aluminium wing 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 ONE pump balancing piece - PAS L180 - with G1½(a)×G1½(i) fittings for balancing one pump DN25, length 180mm, insulated (part no.: 001 338).

Assembly does not contain a pump

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

ATTENTION: CANNOT BE USED WITHOUT SYSTEM SEPARATION!
