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

The version with the air sensor allows the system to work in cooling mode, even when the water temperature is approaching 3 °C. In these conditions the air sensor cuts in to prevent water drainage.

Buffer tanks, either for hot or cold water, have two main functions: they work both as a hydraulic separator and buffer tank.

The hydraulic separator makes the heat pump flow rates and terminals flow rates unconnected. The buffer function reduces the heat pump on/off switching. Hanging energy buffer tanks are designed for wall installation.

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.
