The pack consists of:

2 x iStop® Anti-freeze Valves

The antifreeze valve allows the circuit medium to be drained when its temperature reaches an average value of 3 °C. This prevents ice from forming in the circuit of a system, generally with a heat pump, avoiding potential damage to the machine and to the pipes.

1 x High Flow Bi Pass

The differential by-pass valve is used in systems working with variable flow rates, for example in those making widespread use of thermostatic valves or 2-way motorised valves. It ensures a flow recirculation proportional to the number of valves being closed while limiting the maximum differential pressure value generated by the pump.

1 x 28mm Dirtmag Plus

Dirtmag Quattro Multifunction device with dirt separator and strainer, including compression, ends. The presence of these two components allows for continuous protection of the generator and devices from any impurities that form in the hydraulic circuit both at the time of system start-up and in normal operating conditions.

The CALEFFI XF filter separates impurities in the system right from the first passage. Its large filtration surface and impurity separation upstream of the filter also minimises the problem of mesh clogging.

System water is treated in three distinct steps: an initial separation mesh, a central magnet and an outlet filter.

CALEFFI XF continuously protects the generator and devices from any impurities that form in the hydraulic circuit. It can be adjusted for horizontal or vertical installation.

Internal cleaning brushes mean that maintenance can be carried out without shutting off the device.
