All built-in components are selected for size optimisation in relation to the capacity they are designed for, which results in a truly compact air handling unit. The units also offer low SFP Values and provides more options for indoor connectivity. While constant air volume control (CAV) is standard, variable air volume control (VAV) is available as an accessory.

Built-in Access Control system

All models are equipped with Systemair Access control system with a vast range of energy optimising features which, together with the intuitive user interface in the Access NaviPad control panel, enables an easy and responsive control solution.

The new external Access Control Cabinet gives easy access to external connections and makes the installation and start-up even faster. The control cabinet can be mounted on the air handling unit or separated from the unit using an optional extension-kit and choosing from a 3, 5 or 12-meter cable.

The Access Control Unit provides dedicated connections for BMS, using Modbus and BACnet. The unit also has all connectors for external components clearly marked and grouped together to further reduce installation and startup time.

The Access Control system comes prepared for Systemair Connect, an easy-to-use cloud service providing a complete overview and accessibility of the installed base of air handling units.

All main components are easy to remove and the flexible design of inspection doors ensures an easy shift from one side to the other side of the unit, supporting painless installation and maintenance procedures.

There is also a wide range of accessories available including connectors, such as flanges, cooling coils, extension cables or extra filtration, meaning the units can easily fulfill different customer requirements.
