						Item no. 001 394
						Two-zone discharge
						


						For highly efficient two-zone unloading of a buffer tank in a mixed low-temperature circuit by means of highly efficient operation of a system separation via flow control from the differential pressure of the pump in the heat generator circuit (i.e. without an additional pump in the primary circuit of the system separation!) with highly efficient use of the return flow of an unmixed high-temperature circuit.

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), plug and cover Ms58

For highly efficient two-zone unloading of a buffer tank in a mixed low-temperature circuit by means of highly efficient operation of a system separation via flow control from the differential pressure of the pump in the heat generator circuit (i.e. without an additional pump in the primary circuit of the system separation!) with highly efficient use of the return flow of an unmixed high-temperature circuit.

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

Two-circuit manifold assembly with 3 connections to the heat generator (buffer or boiler with flue gas heat exchanger), CuØ35×1, pipe spacing 100mm, DN32×G1½(a) flat

1 integrated backflow preventer, Dp10mbar and 1 integrated return differential pressure regulator, Dp50-70mbar

Direct heating circuit (HT): Kvs = 9.2 - V'max[100mbar] = 2.9m³/h - Q'max[20K] = 67kW - Mixed heating circuit (NT) with ST DN25s: Kvs = 7.2 - V'max[100mbar] = 2.3m³/h - Q'max[10K] = 27kW - Leakage rate < 0,1%

7 Thermometer 0-120°C, Ø63mm, soldering sleeves Ms58

7 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 on heat generator flow (1)

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 - strong version, PN 10bar, Tmax 120°C

ATTENTION: CANNOT BE USED WITHOUT SYSTEM SEPARATION!
