workflow in a busy kitchen Under Control

minimised size

With a reduced footprint of only (W x L x D) 58 x 93 x 96mm, this is the smallest gas interlock panel/controller in the market today.

Current/air sensing

Current or Air sensing options can be selected as well as both from the same unit!

Easy setup

Very easy to set the required conditions with easy step by step guide.

Digital LED display

With a clear display of the status and conditions, it's now easy to see what is actually happening.

How does a Gas Interlock System Work?

How to install a Gas Interlock System

The gas interlock panel should be mounted on a wall for easy access by all.
A main isolation solenoid valve should be connected to the gas interlock panel.
At least one extraction fan should be connected to the interlock panel. This could be via a fan speed controller. An inlet fan can also be connected to bring in the fresh air.
The gas interlock will monitor the fan speed or air differential pressure. If this is too low it will shut the main gas valve to the cook appliance.
A Co2 sensor can also be used to ensure it is within a pre-defined scope.

Choose the perfect system

You can choose from a complete system for a new installation, panel only or panel and emergency stop button.

Frequently asked questions

The same unit can be used for current sensing or air sensing via a compatable fan speed controller.

Our unit can be used with both current sensing and air sensing at the same time. E.g. extract fan current sensing and inlet fan air sensing.

It has inputs for Co2 and fire alarm sensing that will also close the main valve upon activation.

Yes we do, we have 5A, 10A and 15A versions that can work with our gas interock controllers.

We have stock sizes from 1/2″ to 2″ solenoid valves. All with threaded female connections.
