Air to Water Series is a system that can create cold and hot water and be used with a VRF system
as with the indoor units.
It can supply hot water of up to 70ºC, and can be used in any situation, such as for showers or floor
heating in homes and hotels, as well as for supplying hot water in offices and restaurants.
Using the Air to Water Series in combination with the heat recovery series (R2/WR2-Series) allows
exhaust heat from the cooling operation to be used effectively to create hot water, ensuring efficient
heat recovery operation.
System structure
Air to Water (ATW) Series offers a choice between two types of units: a booster unit and a HEX (heat exchanger) unit.
The booster unit offers hot water to a maximum of 70°C and the HEX unit offers 40°C for heating and down to 8°C for
cooling. Applying heat pump and heat recovery technology to provide hot water, the units are suitable for residences,
office buildings, restaurants and hotels, providing an optimal environment with the benefits of reduced running costs and
reduced impact on the environment.
The ATW system consists of an outdoor unit, a BC controller when connected with the R2-Series, an ATW unit, indoor
unit and controller.
