Vitocal 350-HT: High Temperature Heat Pump for Waste Heat Recovery in Renewable Heating for the Commercial Sector

The use of renewable heat in commercial applications is driven by the need for high flow temperatures.

As a series-produced heat pump, the Vitocal 350-HT Pro high-temperature heat pump delivers a flow temperature of up to 90 °C and uses a heat source temperature of up to 45 °C. This makes it particularly suitable for waste heat recovery and high temperatures for industrial and commercial processes or for older district heating networks.

The use of the new HFO refrigerant R1234ze means that this series of appliances already complies with refrigerant regulations that will remain in place for many years to come. GWP (Global Warming Potential) is in the single-digit range and is therefore almost as low as that of natural refrigerants.

In addition, the control unit has many communication options. LAN-enabled systems as well as Modbus and BACnet interfaces can be used. This makes the system available for remote monitoring and integration into building management systems. The 5.7-inch color touchscreen provides intuitive operation and easy control.
