The iGRAIN Relay Output Unit is a control module designed for automatic control of aeration and head space ventilation fans. The unit is controlled from the iGRAIN Dashboard Manager or control board via RS485 MODBUS. Each unit has 8 relays with NO (Normally Open) and NC (Normally Closed) relay contacts and the status of each relay is indicated with a diode. Each relay unit can be set to an individual address and be installed remotely where the aeration power relays are located. The unit is normally only used for aeration control if there is no PLC/SCADA system available. Advantages • Status and control by iGRAIN Dashboard Manager • Easy control board mount • Operates in either manual or automatic mode via the aeration control software

Northern Air® Aggressive Environment is available in sizes 3, 4 and 5 meters in diameter. As a standard, it comes with several layers of white powder coating. This special coating has been chosen as it provides extra protection against corrosion. The ceiling fan also has an IP54 rating, which makes it extra hardy. It is the obvious choice for challenging and corrosive environments. It can be installed as a stand-alone solution or in tandem with existing HVAC systems. Aggressive Environment has the same benefits as Northern Air® Pro fans. It ensures energy savings and CO2 reductions in winter and reduces the need for air conditioning during summer.

A small white ceiling fan with remote control – that’s the essence of Northern Air® Mini. It measures only 1.5 meters in diameter. Still, it provides maximum performance for its size. The elegant small ceiling fan is ideal for improving the indoor climate in smaller rooms. Eg. canteens, classrooms, offices, and other similar facilities.
