EcoSash® is an innovative device from TPE that dramatically improves the energy saving capability of a variable air volume (VAV) fume cupboard.
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.
The Ecosash has been designed to reduce unnecessary energy loss in laboratories where VAV fume cupboards are operating. This is done by means of automatically closing the fume cupboard door when the operator is not present. Ingeniously, EcoSash 'remembers' to lower the sash door after a pre-set period of inactivity at the fume cupboard. This in turn restricts the amount of conditioned air being extracted out of the laboratory and enhances laboratory safety by always keeping the sash down when practical.
For example, if ten sashes could be lowered to the closed position for 40% of any eight hour period, you will achieve significant savings of over 70% in air volume.
