RVS DC SERIES Chillers for cooling and heating

Chilled water systems
Cooling capacity: 4.7 - 22.5 kW
For use in the commercial and industrial sector

With inverter technology

The units of the RVS 50-260 DC series, with an output range between 4.7 and 26.0 kW, are particularly quiet, air-cooled chillers for outdoor installation. Due to the standard heat pump function, the units can be used for both cooling and heating.
During cooling, the application limits of the units lie at -15°C, whereby the units are also suitable for process applications that have to be cooled throughout the year. Both the inverter condenser used and the infinitely variable expansion valve guarantee a needs-based adaptation of the cooling capacity to the pertinent application conditions.
In addition, the units have state-of-the-art, energy-efficient EC fans in the standard version. These fans provide considerable cost savings in comparison with conventional AC technology, especially in the partial load range. The interaction from the optimisation of the heat exchanger surfaces, use of highly efficient components and the optimisation of all operation-related system parameters ensures that the units have a very high degree of efficiency and therefore already correspond with the high energetic requirements of the Eco-Design Directive 2021.
In addition, the devices are available in a special low-temperature version in which particularly low medium inlet temperatures of -2°C can be implemented.

Variable power control thanks to the inverter condenser and electronic expansion valve
Floating switch contacts for integration into a building control system
State-of-the-art touchpad in an IP54 housing for easy operation
Application of cooling mode up to -15°C, standard
Low temperature version for low inlet temperatures, optionally available
Heating operation thanks to EVI injection down to -30°C outside temperature (RVS 220-260 DC)
