Energy-efficient, quiet split evaporator for outdoor installation
Air-cooled heat pump evaporator with quiet EC fans
High-performance heat exchanger with maximum thermal output per m²
Development and production - made in Germany
Highly efficient heat pump evaporator
With a thermal output of up to 30 kW, the highly efficient, high-performance heat pump evaporator is particularly suitable for use in renovated buildings or new office buildings. Installed outdoors, the WP evaporator takes the energy for the heat pump from the ambient air and impresses with its quiet operation and low operating costs.
The WPV is used in these areas of application
Energy technology
During the generation of energy, waste heat is generated that has to be dissipated or reused. Efficient and robust heat exchanger systems are indispensable for fail-safe energy management. Heat exchangers can be manufactured by Roller in any individual design.
We will be happy to advise you on the design of your specific heat exchanger.
HVAC industry
Today, a multitude of different applications such as server rooms, clean rooms, medical facilities and practices, shops, offices, greenhouses, and so on, place specific demands on building technology.
The right temperature, air quality and air movement play an important role. Here, with individual heat exchangers, we offer suitable solutions for a wide range of tasks.
The robust HKN air-conditioning unit stands for barely noticeable conditioning and a comfortable indoor climate with high energy efficiency.

Office air conditioning- WPV - Kelvin
The company Kelvin ABT GmbH in Günzburg fitted an air conditioning system for cooling and heating in its office building as part of a renovation project. The particularly compact and quiet HKN 50 EC air conditioning units from Roller ensure pleasant room conditions while Roller's HL 050/3 heat pump evaporator functions as an evaporator or condenser for the reversible heat pump.
