What separates the Fresh Air series from plain recirculation is a modulating outdoor air damper. The OXA-FD controls switch between three modes: 100 % fresh air (when it is already comfortable outside, the heating switches off and the boiler house does no work at all), energy-efficient mixing, and full recirculation for background heating outside working hours. It is complete decentralised ventilation for a production building, without a single metre of ductwork.
