Fresh Air Fan Convectors Control CO2 Levels for Schools
March 30, 2015 — 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.
Now, Dunham-Bush has launched a new version of its fresh air fan convectors that fulfills all required criteria, and the system is simple to install, operate, and maintain.
The new 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.
Mike Holding, managing director at Dunham-Bush, said, “Fan convectors are a very effective way of introducing tempered fresh air in response to levels of CO2 while providing a level of free cooling, and are suitable for both new build and refurbishments.”
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, and CO2 levels, and to "boost" heating and other functions.
“As with all Dunham-Bush fan convectors," Holding added, "the units have an all-metal construction, manufactured from sheet steel with radiused metal corners and grilles. The units feature secure access panels, resulting in a robust and safe product which is ideal for the rigorous standards demanded in schools and public buildings.”
