Key Benefits

Efficient solutions for professional applications

The Pro series of the Vitocal 300-G Pro heat pumps features all the characteristics of the highly efficient Vitocal 300-G series.

The five output ratings enable most requirements from residential and commercial buildings to be reliably met.

These appliances are standardised, enabling quick and comprehensive engineering, as well as transparent cost calculation.

Space efficient design

Just 88 centimetres wide, the Vitocal 300-G Pro can be handled easily to its installation site using the lifting clearance integrated into its base. For higher outputs, up to five units can be connected in a cascade.

Optimised appliance construction for quiet operation

As is the case for all heat pumps, the compressors emit noise in the 50 to 60 Hz range. Due to the high quality construction of the frame and anti-vibration casing components, it has been possible to keep this noise within the casing. 

Vibrations on the base support are barely perceptible as the 3-D antivibration construction is specifically designed to dissipate oscillations. With sound power levels of, for instance, 65 dB (A) for the 197 kW heat pump, its values stand up well by comparison with other products in this market segment.

Pre-assembled electrical equipment

The electrical equipment is already integrated inside the heat pump casing as standard. Factory-fitted contactors for fail-safe primary and secondary pumps, as well as  protection for the compressor, guarantee straightforward installation and the safe and rapid integration of the large heat pump into the system.

Proven and reliable technology

The control philosophy was adopted from the Vitocal series for detached and semi-detached houses. Here too, the Refrigerant Cycle Diagnostic System (RCD) checks efficiency continuously and safeguards the efficient and reliable function at any operating point through the interaction between the electronic expansion valve (EEV) and the extensive sensor technology. The Vitotronic 200 regulates up to three heating circuits, and thanks to its natural cooling function ensures pleasant ambient conditions on hot summer days. 

With the optional addition of a Vitocom 300 communication module, a comprehensive range of settings and system optimisations can be undertaken from anywhere via internet or mobile phone.
