ZEWO Heat pumps AERO SLM 3-11 kW / 6-17 kW

Best performance for carefree living, living and working

The heat pumps with output values of 3-11 kW and 6-17 kW are convincing in function, technology and appearance. Heating, cooling and hot water preparation for single-family homes is child's play for this product series. The heat output of the heat pump is infinitely variable by modulation between 3 kW and 11 kW or 6 kW and 17 kW to match the actual heat requirement. The use of high-quality components and CIC inverter cooling make this product version a highly efficient solution.

The air-source heat pump AERO SLM 3-11 kW / 6-17 kW is a modulating air-water heat pump in split design with inverter-controlled scroll capsule compressor. With the optional hot gas charging technology (HGL technology), up to 60°C for hot water preparation can be achieved through the hot gas heat exchanger and charging valve already integrated in the heat pump as well as the special control sequence during heating operation. Active cooling is possible as standard.

Thanks to state-of-the-art inverter technology, stepless power adjustment is possible. The speed-controlled compressor therefore only generates the energy that is needed. The NAVIGATOR 2.0's 7" colour touch display facilitates operation of the heat pump. The display can be removed from the housing and installed in the living room, for example. The cold-side connection lines to the outdoor unit can be connected either on the right or left side of the indoor unit. The connections on the heating side are either on the right or left side. The electrical connections and the connection for the LAN connection are on the rear. The heat pump complies with current EU standards and regulations.

The indoor unit is filled with R410A safety refrigerant and factory tested for functionality. The outdoor unit is prefilled with nitrogen. Refrigerant must be refilled from a pipe length of 6 m between the indoor unit and the outdoor unit.

The indoor unit and outdoor unit can be placed at a maximum distance of 20 m from each other and with a maximum height difference of 10 m. The maximum distance between the indoor unit and the outdoor unit is 20 m. Up to a pipe length of 15 m (3-11) or 6 m (6-17), no annual leak test is required.

A comprehensive range of product accessories for control, connection to the heating side, for cooling, etc. can be found in the overall PREMIUM heat pump price list, which you can find in the downloadarea.

Heat pumps with HGL technology offer an even more cost-saving solution! Versions with hot gas charging technology transfer 85 % of the energy at 35 °C to the heating circuit. The remaining part reaches up to 62 °C for water treatment and is available via the hygienic storage tank with fresh water technology! This produces fresh hot water in seconds. Only the heating water is stored, the drinking water is always freshly heated. This means that microorganisms such as Legionella or other bacteria have NO chance!

Simply perfectly controlled

The intelligent control of the heat pump is carried out via a modern 7" touch panel. In addition to simple operation, it also includes extensive features that can be used to increase living comfort and optimise energy utilisation. Click here for more information.
