Crowcon Fixed Gas Detectors
Thorne & Derrick, Experts in Equipment for Explosive Atmospheres, are Specialist Distributors of Gas Detection monitors and instruments for detecting oxygen, flammable and toxic gas hazards in industrial and hazardous area locations with explosive atmospheres – the gas detectors manufactured by Crowcon are economical, reliable and innovative.
Crowcon gas detectors, both fixed and portable, provide life saving alerts and notice of the presence of potentially fatal gases in working areas. Typically, a fixed gas detector is used as a permanent gas monitoring solution installed in a specific location such as a process area of a control or a plant room.

Gas Detectors
Fixed gas detection uses the latest technology to ensure the safety of plant and personnel at all times. In the event of a gas concentration reaching a preset high level, fixed gas detectors have alarms, lights and indicators that act as a warning signal to alert the user of the gas risk hazard in both safe and hazardous area zone locations.
The below webinar is taken by Will Allum Product Marketing Manager at Crowcon for fixed gas detection systems.

Fixed Gas Detector Communications
For many fixed gas detector operators the go to communication type is the conventional analogue ‘point to point systems’ that has been around for many years. Reliability offers operators reassurance when they are dealing with familiar technology and functionality.
However the development of digital & communication technologies allows further information to be processed and sent to a control system dramatically reducing the cost.
GM Controller By Crowcon
Crowcon’s GM Controller range is user friendly with a simple set up allowing up to 64 channel addressable by the controller.
- Options for 16 / 64 / 128 channel capability controller which provides simultaneous display and alarm functions for up to 64 input variables on one screen (GM128 has twin screens)
- 4-20mA analog, RS-485 MODBUS & HART enabled communications as standard.
- Addressable functionality enabled
- Direct to web page live feed communication
- Local non-intrusive operation or via direct web page configuration
- Colour LCD display – Monitor live data & trends. Colour change to indicate alarm
- Available in rack or enclosure mountings

Crowcon GM Controller
3 fixed gas detector heads available allows for digital communications –
- Xgard Bright : Versatile detector with digital comms and non-intrusive operation via OLED display window.
- Xgard IQ : Intelligent Gas Detector and Transmitter, with smart sensor modules with SIL2 certification.
- IRmax : Infrared (IR) gas detector that delivers rapid, fail-safe detection of hydrocarbon gases and vapours
Remote visibility & control
Fixed gas detection system can be mounted in potentially hazardous locations, and access to the system is necessary for general maintenance and key task completion.
Crowcon GM controller range once connected to a network allows access to a ‘Direct to webpage’ feature. A controller IP address is activated and can be found in the controller network settings.
The IP address can be entered into any device with internet access and the user will be able to remotely login in to the same functions that are available at the controller panel.
Crowcon suggest that you look for possibilities where addressable systems or remote visibility could offer a distinct advantage and an alternative solution to your installation or operations.

Distributors of Gas Detection Monitors & Instruments
Flame, Heat, Gas Detectors & Detection Systems
Hazardous area industries including offshore oil/gas platforms and FPSOs, onshore oil refineries, processing plants, pipelines, storage farms and LPG/LNG plants all utilise or produce a wide range of hazardous flammable liquids and gases that can be detected using correctly specified flame and gas detectors.
Detecting toxic and flammable gases requires the detectors to be classified and certified according to the specific IECEx or ATEX standard – we distribute flame and fire detectors manufactured by Spectrex to operate in the harshest environmental conditions including self-contained stand-alone devices designed for direct connection to control and alarm systems or automatic fire extinguishing systems.
Our range of Hazardous Area Fire & Gas Detection System products also includes Explosion Proof Warning Systems & Hazardous Area Lighting – comprehensive range of intrinsically safe, flameproof and explosion proof alarm sounders, sirens, bells and horns, loudspeakers and beacons.
