ADVERTORIAL: How Protex Systems can help install the right fire and gas detection systems with breakthrough laser technology

With orders rapidly rising, Protex Systems has the technology to help firms across the UK strengthen their workplace safety by installing one of the leading gas detection systems.

Protex Systems specialises in providing fire and gas detection equipment and solutions to a range of industries in the UK and overseas, both on and offshore.

The Stockton-based company is also a Channel Partner to MSA, a manufacturer of Flame and Gas Detection equipment. One of MSA’s most cutting-edge gas detection systems is the Senscient ELDS.

Senscient ELDS

Designed to provide the utmost in safety, the Senscient ELDS laser-based Open Path Gas Detector (OPGD) rejects nuisance false alarms, detects more fugitive gas leaks over wider areas, and automatically verifies full end-to-end functionality every day. With solutions for both toxic and flammable gases, Senscient ELDS takes gas detection to the next level with its breakthrough technology and can offer lower operational costs by more than 80%.

The Senscient ELDS requires no calibration during the lifetime of the product, saving time and money. The Sencient ELDS can be used for the following gases:


Carbon Dioxide


Hydrogen Chloride

Hydrogen Fluoride

Hydrogen Sulfide


Sour Gas (Methane & Hydrogen Sulfide)

Established Company

Protex Systems has just celebrated its tenth anniversary. Founded by David Orr, the independent business has experienced substantial growth.

A graduate of Teesside University (specialising in Instrumentation and Control) and with an MBA from the University of Strathclyde, David has decades of experience in managing companies both internationally and in the UK and he has over 20 years’ experience of fire and gas products, field support services and design work.

In addition to supplying products, the business also offers a design service called Fire and Gas Mapping. In 2015, David worked on a two-year KTP (Knowledge Transfer Project) with Teesside University to develop software that is now used to support many of the leading energy and oil and gas companies to design and develop their fire and gas detection strategies helping to support the safety of their personnel and protect their assets.

In 2018, David was part of a working group that developed a new British standard for what is known as Fire and Gas Mapping, BS 60080:2020 Explosive and toxic atmospheres — Hazard detection mapping was developed over a two-year period and was published in 2020.

David said: “We offer the most advanced safety equipment available today. We work with countless businesses from University Laboratories to manufacturing sectors and support their efforts to focus on personnel and workplace safety.

“Undetected gas leaks in production plants and storage facilities can have devastating consequences, including accidental yet catastrophic explosions, fires, loss of life and worker health issues. These effects can potentially extend to nearby communities, damaging the environment and company reputations along with it.

“Effective, reliable gas detection systems are an essential layer of protection designed to reduce risk and protect all stakeholders. A number of detection technologies exist all designed to suit a specific wide range of applications. To help the businesses better address various gas detection concerns especially in wide areas, open path technology enhances the overall safety performance of the gas detection system.

“Open Path Gas Detectors (OPGD) which use Non-Dispersive Infrared (NDIR) detection techniques have been in use since the late 1980s and are widely accepted for many oil and gas, petrochemical and other industry’s combustible gas detection applications.

“MSA/Senscient launched its range of laser based OPGD using a technique called Enhanced Laser Diode Spectroscopy (ELDS).

These devices:

Detect not only combustible gases like Methane and Ethylene, but also toxic including: Hydrogen Sulfide, Hydrogen Fluoride, Hydrogen Chloride, Carbon Dioxide Ammonia and Sour gas (Hydrogen Sulfide entrained within Methane).

Offer three orders of magnitude in increased sensitivity for hydrocarbons, greatly increasing the probability of detecting a flammable gas leak. At the same time it is less prone to water vapor interference, increasing uptime availability in challenging weather such as fog, rain, or snow.

Include the unique self-test facility called SimuGas™ that enables automatic or on demand functional testing of open path gas detectors locally

David added: “If you are looking for a complex integrated addressable/PLC based Fire and Gas systems or a simple card based design our engineers are available to meet you to discuss your specific targets.

“We want our customers to benefit from our experience, expertise and independence. The depth of fire and gas knowledge and our ability to apply a diverse range of technologies has established Protex Systems as a leader in providing the right solution, whatever the requirement.

“We can provide a solution in the most challenging situations, whether using an ‘out of the box’ solution or a bespoke designed system. We always fully support our customers by ensuring comprehensive engineering and support capability throughout the solution providing process and over the lifetime of the equipment.’’
