Freshvector from Dunham Bush
Freshvector is an innovative new product from Dunham Bush that combines passive, natural ventilation with the company’s Finvector perimeter heating system. As such it addresses the need to ensure high air quality with minimum energy consumption and low noise in classrooms and many other applications.
Specially developed vents with motorised dampers and attenuators are fitted into the wall of the building, allowing fresh air to be drawn across the high level heating elements using the ‘stack effect’. As a result, the fresh air is pre-heated and draughts associated with conventional ventilation are eliminated.
The dampers on the vents are controlled initially by carbon dioxide levels in the space, with the option of temperature override as well. If required, sections dedicated to fresh air heating load and building fabric heating loads can be controlled independently. A rain sensor can also be incorporated where position and orientation make this necessary.
Finvector has a nominal output of 1100W per linear metre at 75°C MWT, and 18°C EAT and casings are available in a range of styles to suit different decors.
