Air Flux 6300A C

Air Flux 3-pipe VRF heat recovery outdoor unit with up to 50 kW which is cascadable with 3 outdoor units. This range of outdoor units is compatible with all indoor units and Bosch developed controls. In combination with the Air Flux hydrobox, hot water can be produced.

  • The AF6300A C is equipped with a DC inverter scroll compressor. In combination with 3 outdoor units a capacity of up to 150 kW can be covered
  • Extended range of switch boxes with 6 different models available
  • Smart energy management
  • Easy service and maintenance
  • Wide operation range in cooling and heating mode with up to 1000 m piping length
  • Maximum piping length is up to 175 m with a combination ratio of 200 %


High comfort with easy cooling and heating

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.

Compact design

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.

Smart energy management

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.

Easy service and maintenance

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.

Wide operation range

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.
