Products: Airflow Controls

Our range of VAV controls are designed specifically to provide variable airflow volume and ensure the safety of users working with industrial and educational fume cupboards, fume hoods and biological safety cabinets.

As many fume cupboard ventilation systems are full fresh air type a high amount of energy is wasted when the fume cupboards are not in use. Converting to VAV can reduce volumes by up to 85%, reducing both energy costs and carbon emissions. TEL offers a full retro fit service and is making a considerable impact on how organisations meet their carbon reduction targets.

Product Benefits:

Safety and compliance

Protecting your staff from potentially hazardous fumes and substances and ensuring you stay compliant.

Energy and cost savings

The TEL VAV airflow controller reduces the volume of air taken from the fume cupboard when it is not being used, reducing energy usage by up to 85%, considerably reducing costs.

Carbon emissions reduced

With many organisations having to meet carbon reduction targets, TEL’s VAV airflow controller reduces energy wastage, ensuring reductions in carbon emissions.

Reliability

With no inherent drift, the unique sensor will provide stable readings over many years of operation without re-calibration, ensuring reliability and safety.
