Energy Saving Technology

At Clean Air we have an on-going R&D programme to continuously improve the energy saving technology in our fume cupboards and extract systems, helping you to cut your costs and reduce your environmental impact while keeping your staff safe and enhancing their working environment.

Clean Air’s expert team will guide you to the system that best suits your requirements – just contact us to discuss our energy saving technology options.

Energy saving technology for fume cupboards

In laboratories featuring fume cupboards the air extracted through the fume cupboard must be replaced. This is typically achieved with heated or cooled outside air. The introduction of low volume and/or VAV fume cupboards can not only reduce running costs, it can also stabilise the ambient temperature within the lab as the volume of air extracted is reduced. This reduced extraction can in turn result in a noticeable reduction in noise. A further benefit is reduced capital costs as smaller extract ducts and fan sizes may be installed.

Constant Air Volume (CAV) Fume Cupboards

CAV fume cupboards consume air regardless of sash position, therefore to reduce energy consumption the fume cupboard must be turned off when not in use.

Low Volume Fume Cupboards

Clean Air Low Volume fume cupboards are carefully designed to achieve good containment levels while operating at lower face velocity, typically 0.3 m/s. This can lead to a 40% energy saving in the costs of heating/cooling replacement air compared to a traditional 0.5 m/s face velocity fume cupboard.

Variable Air Volume (VAV) Fume Cupboards

VAV fume cupboards feature energy saving technology to reduce the volume of air taken from the fume cupboard. To maximise the benefits of this technology Clean Air recommends VAV fume cupboards are fitted with an auto sash controller to monitor the position of the sash and automatically close it when not in use. While there is an increased capital outlay for the control systems the two controls in combination will reduce energy costs dramatically. VAV and auto sash fume cupboards can achieve energy savings of up to 75%.

Retrofit VAV to existing Fume Cupboards

Significant energy savings can be made by upgrading existing CAV fume cupboards to VAV. The upgrade is undertaken by our fast, efficient service engineers and comprises a VAV Alarm/Control panel, sash position sensor and motorised dampers within the extract ductwork.
