Current guidelines for school classrooms demand that CO2 levels be controlled through the introduction of fresh air, in an effort to improve indoor air quality. In addition, classrooms must be light and energy-efficient, and equipment must respond quickly to changes in occupancy or outdoor conditions. Dunham-Bush has launched a new version of its fresh air fan convectors which fulfils all required criteria, and its a system which is simple to install, operate, and maintain.
Dunham-Bushs new range of fan convectors contain a fresh air inlet with modulating dampers controlled by CO2 levels. The units heat fresh air and are equipped with frost protection and thermostats to make sure comfort levels are maintained safely.
The models are designed specifically for fresh air and include two low-level floor-standing or wall-mounted models, a ceiling mounted version for use over windows and one taller model. Each is available in five sizes so the range has something to suit most applications.
Each unit is available with EC motors, ideally used with condensing boilers, and includes a washable filter. They can be integrated with all Building Management Systems (BMS) in order to control heat output, fan speed, warm up times, CO2 levels and boost heating and other functions.
