With up to 150 kW you can design systems for many use cases where heating and cooling mode at the same time is needed. High quality DC inverter scroll-compressors with vapor injection ensure reliable operation. Compressor models have an extended compressor speed from 15 Hz to 140 Hz.

The new range offers compact dimensions with a height of only 195 mm for AF-SB 01-1L and 250 mm for other models, and easy to install switch boxes. Up to 8 indoor units can be connected to one port for AF-SB 01-1L, up to 60 indoor units can be connected to one AF-SB 12-1. By combining 2 ports, a connection up to 28 kW is possible. A model with leakage detection is available.

The evaporating temperature (in cooling) and condensing temperature (in heating) are automatically adjusted according to both indoor and outdoor temperature to maximize the comfort and energy efficiency.

The digital display on the data transfer module displays the same information as the digital display on main PCB. This allows quick and easy service and maintenance with simple data access.

You can profit of a wide temperature range in each operation mode:
For dry bulb the range is -15 °C ~ 52 °C for pure colling mode, for mixed mode -15 °C ~ 27 °C.
For wet bulb the range is -25 °C ~ 19 °C in pure heating mode and -15 °C ~ 19 °C for mixed mode.
