DomvS Circ 1

Hot domestic water recycling kit for storage tanks with coils. 35÷60°C.
The kit allows to connect  the recycling way of the hot domestic water to an instantaneous storage tank with coils in a very symple way. The pre-assembled kit, by means of a stainless steel flexible pipe, makes a counter-current circulation that warms the water along the recycling way.

Two models are available:
  • Kvs 2,5 for small use.
  • Kvs 4,0 for medium use.
Working features:
  • Anti scald thermostatic-mixer.
  • Adjustable control of the temperature to the user  by means of a knob from 35°C up to 60°C.
  • Possibility to lock the rotation of the knob.
  • Check valve built into  the inlet  fitting of cold water.
  • Circulating pump (in the model that include it) for the recycling way equipped with temperature sensor to restrict its working, keeping the water inside the pipe at the selected temperature. The pump automatically stops when the water temperature gets to the value set on the body of the motor (between 20 and 70°C).
  • Circulating pump (in the model that include it) equipped with temperature sensor and timer for a better energy saving.
Technical features
  • Maximum static pressure 10 bar (PN 10); dynamic 5 bar.
  • Maximum ratio between the pressures: 2:1.
  • Maximum inlet temperature: 95°C.
  • Setting temperature range: 35-60°C.
  • Setting stability: ±2°C (Kvs 4,0); ±1°C (Kvs 2,5).

PED 2014/68/EU 4.3
Available Kvs:
2.5 = Maximum Kvs 2,7; up to 55 l/min (1,5 bar).
4.0 = Maximum Kvs 4,0; up to 82 l/min (1,5 bar).

Available circulating pumps:
With temperature sensor (R)
With temperature sensor and timer (RU)

Recycling working way

When the circulating pump starts, the cold water into the recycling loop, flowing through the flexible pipe, comes back warmed towards the gate H of the mixer; the gate C of the mixer is usually closed until when the temperature of the recycling loop is not near to the one selected on the mixer (this condition  is  unlikely to be happened).
The recycling circulation into the recycling loop is working until the circulating pump sensor or timer are satisfied.
