Beschrijving
The variable air volume models allow the volume of heated make up air to vary to suit the changing requirements of the building or changing exhaust rates.
The units are fitted with a special box burner system complete with integral fan(s) to ensure optimum combustion throughout the range of varying volume main air supply.
The units supply 100% fresh air at all times but the volume of fresh air is automatically adjusted either by the application of a building pressure sensor or temperature sensors.
The building pressure sensor can be set to maintain either a slight positive or negative pressure inside the building to suit the requirements of the application.
When used for space heating, temperature sensors adjust both the air discharge temperature and the supply air volume to provide a rapid warm up and maintain minimal stratification levels.
