Volumetric Controls

Our innovative volumetric controller is designed to provide variable airflow volume control and ensure the safety of users working with industrial and educational fume hoods. As well as mitigating risk, the Volumetric airflow controls reduce energy consumption and carbon footprint.

The Volumetric controller utilizes a bell mouth type venturi restrictor to accurately measure the extract volume of the fume hood and provides VAV control based on either sash position, programmable fixed set points or 0-10VDC analogue input.
The controller can also operate using 3rd party orifice plates or other manufactured restrictor devices.


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

Energy and cost savings
The TEL Volumetric Controller reduces the volume of air taken from the fume hood when it is not being used, reducing energy usage by up to 85%, considerably reducing costs.

Carbon emissions reduced
With many organizations having to meet carbon reduction targets, TEL’s Volumetric controller reduces energy wastage, ensuring reductions in carbon emissions.
