GIL-Open Path Gas Detection for Process Optimization

oppthOpen path gas detectors (OPGD) are available for the detection of combustibles (LEL) as well as toxic (e.g., H2S) gas leaks at varying distances (up to hundreds of metres). Each detector is made up of a transmitter and receiver unit, mounted in opposite direction without any obstruction. Over the years, OPGDs have found divers applications in FPSOs and various offshore platforms, Gas and petrochemical/chemical processing plants, just to mention a few. GIL Automations has carved a nitch for herself in the aspect of gas detection systems especially using the OPGD technology. GIL has delivered several hundreds of OPGD units across Sub-Sahara African region within the last five (5) years while also providing back-end support to customers.

We have an extensive reference list of deployed OPGDs for facilities optimization across  upstream & downstream sectors.


oppth1One major advantage of open path gas detectors over the conventional point-type gas detectors is their wider distance of coverage. Another advantage is that the incorporated heated windows help to minimize any possible effects of condensation, icing and snow. It also makes the detectors immune to interference from sunlight or any other sources of radiation such as flare stacks, arc welding or lightning. Faster speed of response (reduced response time) and immunity to false alarms are also some of the merits of these range of detectors, thus, ensuring the safety of assets across various facilities. The detectors come with different outputs (mA, HART, Modbus) to aid their integration with control systems.

In GIL Automations we solve your gas detection problems! We make it easy for you. Above all we ensure all customers requirement are met based on their specific needs- AND is cost effective and less troublesome.
