EcoSash® is an innovative device that dramatically improves the energy saving capability of a variable air volume (VAV) fume cupboard. A frequently selected option on new VAV fume cupboards, the EcoSash® Retrofit Kit offers similar energy savings for existing VAV fume cupboards – regardless of who manufactured them.
A VAV system reduces the exhaust of conditioned air through the fume cupboard at lower sash heights; however, the energy saving benefit accrues only if the operator remembers to lower the sash.
Ingeniously, EcoSash® “remembers” – it automatically lowers the sash door after a pre-set period of inactivity at the fume cupboard. With the EcoSash® system, energy savings are certain, not just possible. As an added bonus, EcoSash® enhances laboratory safety by always keeping the sash down when practical.
