Floor to ceiling air quality for Stannah Stairlifts

Published:  02 September, 2007

Space heating and the control of smoke and welding mist produced during the manufacture of Stannah stairlifts are both handled by a Nordair-Niche variable-air-volume heating and ventilation system.

The installation of a Nordair-Niche variable-air-volume heating and ventilation system is delivering excellent air quality in the factory of Stannah Stairlifts at Andover, a building taken over by the company earlier this year and refurbished. The principal requirements were to be as fuel efficient as possible for this size of factory and for air to be controlled by removing smoke and welding mist produced during the manufacture of the company’s stairlifts.

The production process involves considerable welding, generating smoke and haze that has to be removed to avoid adversely affecting air quality and working conditions.

The heating/ventilation system comprises two variable-air-volume gas-fired warm-air heaters installed outside. They deliver heated fresh air into the building and can also extract air at a rate of 32 m3/s. The extract system has carbon filters to clean the air, and some of it is returned to the building so as not to waste heat.

The system is controlled by a Trend automated control system that constantly monitors internal conditions and varies the volume of incoming and extract air according to both air quality and temperature.
