    Celsius anticondensing pump unit

    Properties:

    • Complete assembled units.
    • Space-saving, it has minimal space requirement due to compact design.
    • Insulated, the assembled units have an insulating cover.

     

    Application:
    The anti-condensing pump unit can be connected directly to the solid heating source in the heating system or to the buffer tank without any additional device. The pump unit is housed in a compact insulation box which includes the circulation pump, the anti-condensing thermostatic valve, the on/off natural circulation clapet valve, the isolating valves and thermometers. It automatically adjusts the returning water to the heating source at the selected thermostat value setting.

     

    Technical features:

    • Synchronous high efficiency Wilo Yonos Para RS/7-RKC circulating pump with progressive speed control.
    • Max. working pressure 10 bar
    • Max. temperature 100°C
    • Setting temperature 55°C
    • Natural circulation clapet valve: with external control, it can be set on or off according to the type of installation.
    • Temperature thermometers: 0-120°C.

     

    Nominal opening temperature: setting temperature + 10 K.
    The max. usable power up to 80 kW (at Δt 30 K) with synchronous circulating pump Wilo Yonos RS/7-RKC.

     

    Working mode:

     

     

     

     

    Starting the installation (boiler warming up):
    After the starting of the boiler, the thermic valve is fully closed towards the user’s return (gate A) and this condition remains until the fluid, warmed up by the heating source, gets the opening temperature of the thermic valve (corresponding to the setting value, f.i. 55°C). During this step the fluid sent by the boiler fully recycles through the by-pass (gate B) and the boiler temperature rises very quickly.

     

     

    Loading the installation (tank warming up):
    Achieving the opening temperature (f.i.55c), gate valve A proportionally starts to open while gate valve B proportionally starts to close. The boiler temperature slowly rises providing energy to the user, however the return temperature will not decrease below the setting temperature (f.i. 55c)

     

     

    Working installation:
    Starting from the condition of point 2, the supply temperature progressively rises up to the full opening of the thermic valve (gate A) and up to the corresponding shutting of by-pass (gate B). This happens at about 10 K more than the opening or setting temperature (therefore in the example in hand, at about 65°C). Now the installation is on working and the supply fluid temperature can rise up to the set value.

     

     

    Natural circulation:
    The natural circulation of fluid through the clapet valve starts as soon as the circulating pump stops and the remaining energy of the heating source is transferred to the water tank. This function starts as a security device, when the pump stops due to blackout or failure, so avoiding that the temperature of the heating source can reach high levels of danger. To turn on the natural circulation function please turn the control screw anti-clockwise.
    You can lock the clapet valve any time, turning the screw clockwise (this operation has to be done when the pump is working).
