The Vitocal 350-G Pro is particularly suitable for modernising heating systems with high flow temperatures.
Vitocal 350 G Pro – delivers flow temperatures up to 73 °C
The frame design makes the powerful and efficient Vitocal 350-G Pro brine/water heat pump easier to handle and install. The sound insulated casing (supplied separately) offers a snug fit and reduces the transport weight by around 200 kilograms. The unit is ideal for modernising heating systems with high flow temperatures.
Depending on the output, two or three compressors are integrated into the refrigerant circuit by way of a compound connection. This guarantees high levels of efficiency, even in partial load operation. The utmost reliability is achieved through the use of electronic injection valves, which are self-closing at zero volt to ensure maximum safety if there is a power failure, for example. Additionally, the hermetically sealed design with fewer threaded connections, and the absence of safety valves in the refrigerant circuit, guarantee tightness and a long service life.
For optimum control of the system and refrigerant circuit, the Vitocal 350-G Pro features a PLC-based Vitotronic control unit. The large graphic touchscreen enables intuitive operation. Its full colour mode highlights the different way that functions and operation are displayed.

The control unit recognises numerous data communication options. From a simple analogue modem to a LAN-based system: Modbus technology and BACnet (both optional) can be used to enable the system to be accessed via the internet for remote maintenance and communication purposes.
As is the case for all heat pumps, the compressors generate noise in the 50 to 60 Hertz range. Due to the very high quality construction of the appliance frame and sound insulation, it has been possible to compensate for any noise within the casing. Vibrations on the base support are barely perceptible, as the 3D anti-vibration design is specifically constructed to dissipate vibrations. The sound power level of 65 dB(A) for the 197 kilowatt heat pump is very good for this market segment.
The electrical equipment is already fully integrated inside the heat pump. The contactors for the circulation pumps are prefitted and easily accessible. In addition, the heat pump offers a wide range of control extensions, which are directly integrated at the factory.
