We are pleased to introduce our NEW Gas Interlock Controller. With the release of this controller, it now makes it easier to install, use and comply with the British standard BS6173.

The new design has a much smaller footprint, therefore, taking less room. This is the most comprehensive Gas Interlock control unit we have introduced to the market. From the same panel, it is possible to use the builtin current sensors and sensors at the same time. The controller is also provided with the ability to be connected to a Co2 sensing and fire alarm input.

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.

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.
