Gas Detection, Proving and Interlocking Systems
At Medem, we design and manufacture all our systems for gas detection, gas proving and interlock safety. With decades of experience and a deep understanding of technical and regulatory standards, we ensure reliability and safety in every product we build.
Gas Detection, Valve Control and Monitoring
We have a range of gas detection systems designed for valve isolation and monitoring applications. We have systems that accept from 1 to 32 gas detectors including options for non safe areas (ATEX).
Gas detectors options include:- Event logs.
- Battery back ups.
- Low and high level alerts with options for isolating a connected gas valve.
- Multiple relay options are available for external signaling.
- Thermal links, emergency stops, fire alarms can also be monitored.

Gas Detection for Commercial Laboratory
In commercial laboratories various hazardous gases may be used, stored or produced.
Common gases found in laboratories include flammable, toxic, inert and oxidizing gases, each with specific risks.
See our range of gas detection systems for commercial laboratories

Gas Detection for Monitoring
Gas detection systems designed to provide continuous monitoring of the environment, providing alerts if unsafe gas concentrations develop.
From standalone units to systems with up to 32 sensors covering a range
different gas types, both common and more exotic.

Gas Detection for Valve Isolation
Gas detection systems designed to isolate a connected valve in the event of a unsafe environment being detected.
Systems cover a range different gas types, both common and more exotic, providing local valve isolation and alerts.
Gas Pressure Proving
Each Medem proving system features our patented differential gas pressure proving method, the only true non-assumptive approach for performing downstream integrity checks. These systems provide accuracy and reliability by directly measuring pressure differentials during the test.
Our proving systems are versatile and can be configured for various gas pressures up to 10 bar, with optional degreasing for use with oxygen supplies. Gas detection and ventilation interlocking depending on the intended application is included.
