W series outdoor unit (28–56 kW)

The W series covers the heating, cooling and hot water of a commercial building from the same platform. It is built in six capacities: 28 / 35 / 40 / 45 / 50 / 56 kW. For larger demands, several units are run together in combination; when the load falls, some units drop out and efficiency is maintained at part load. All models use R410A refrigerant and DC inverter compressors; water can be heated up to 55 °C.

At low temperatures

The units deliver their rated capacity down to −15 °C outdoor air and keep running until it drops to −32 °C. Thanks to the İYB control working together with the ejector, defrost is needed less often and operation stays stable in cold weather.

Casing

The condenser is made of U-bend copper tubes and coated with epoxy, which reduces the risk of deformation under salt, humidity and other external effects. The speed of the BLDC fan varies with the load, and the compressor compartment has insulation and a silencer.

Monitoring and automation

When a fault occurs, the control board sends the error code both to the indoor units and to the service centre. The system can be connected to building automation and monitored remotely.

For commercial projects

Business centres and office towers, hotels, dormitories, schools, sports halls, the office buildings and production areas of factories, and the central systems of residential complexes are the typical applications of this series. It also serves plants that use hot water in their processes.
