Vitocal 300-G

The powerful Compliant scroll compressor fitted in the Vitocal 300-G heat pump is outstanding on account of its high operational safety, reliability and especially quiet operation. Essentially, this is due to the double sound insulation measures that include anti-vibration mounts to prevent structure-borne noise and insulation of the casing against airborne noise. At the same time, the compressor guarantees the highest coefficient of performance (COP up to 5.0) and flow temperatures up to 65°C.

The Refrigerant Cycle Diagnostic (RCD) system constantly monitors the refrigerant circuit in the Vitocal 300-G and, in conjunction with the electronic expansion valve, ensures the highest efficiency at any operating point, which results in high seasonal performance factors.

For residential buildings with a higher heat demand, the two-stage Vitocal 300-G based on the master/slave principle is the right choice. It can also be configured for the ground or groundwater as the heat source. For this purpose, two heat pumps are linked together. This delivers the high heating output required and increases the operational reliability of the entire system. The modular layout, with separate compressor circuits, also ensures particularly high levels of efficiency in partial load operation, and enables the simultaneous operation of central and DHW heating.

With five output stages as a master or master/slave version, various combinations can be realised and matched to the required heat demand. Because of this flexibility, systems can be configured so that runtimes match demand, thus ensuring economical operation. The master module regulates the slave module. Furthermore, the entire system can be equipped with high efficiency pumps.
