XgardIQ

The new XgardIQ, our most intelligent fixed-point gas detector, increases safety by minimising the time operators must spend hazardous areas.

This versatile transmitter and gas detector has a range of features that protect engineers and support facilities managers of oil, gas, chemical & petrochemical plants to name a few.

Available fitted with a variety of flammable, toxic or oxygen gas sensors.

XgardIQ is an intelligent and versatile gas detector and transmitter compatible with Crowcon's full range of sensor technologies. Available fitted with a variety of flammable, toxic or oxygen gas sensors.

Providing analogue 4-20mA and RS-485 Modbus signals as standard, XgardIQ is optionally available with Alarm and Fault relays and HART communications. The 316 stainless steel are available with three M20 or 1/2"NPT cable entrie

XgardIQ

The Xgard range is a comprehensive selection of fixed point gas detectors that meet the diverse requirements for gas detection in industries throughout the world. This includes many water treatment, oil and gas, power, research facility and manufacturing installations.s Detectors detect the presence of gases in an area

Intrinsically Safe (I.S.) or Flameproof (Exd) versions are available, with case options comprising high-grade alloy, stainless steel or chemically resistant GRN polymer. Certifications include IECEx, ATEX, UL, GOST-R and MED.

 IREX

IREX is a fast response sinter-free, fully featured infrared gas detector that produces an mV Wheatstone Bridge output as used on conventional pellistor based systems.

Designed to allow easy upgrading of existing pellistor based fixed point gas detectors.IREX replaces old pellistor heads by simply mounting on the original junction box and connecting to the original cable. The IREX concept enables upgrade to dual-wavelength IR gas detector technology without incurring the very significant costs associated with replacing the control system and re-installation.

Independantly tested for reliability and performance in harsh offshore conditions by Micropack Engineering Ltd - demonstrates IREX will operate dependable in any application
3rd party approval to the performance standard EN60079-29-1
Employs sophisticated systems and algorithms - ensures reliable operation at all times
T90 response time of less than 4 seconds - rapid indication of hydrocarbon gas hazards
Optical components are treated with a STAY-CLIR coating - prevents partial obscuration in condensing atmospheres

IRmax

IRmax is an ultra-compact infrared (IR) gas detector that delivers rapid, fail-safe detection of hydrocarbon gases and vapours. The IRmax gas detection system offers the choice of a detector only, a local gas/status display, a remote gas/status display or non-intrusive calibration via an I.S. calibration tool or hand-held HART communicator.

The reliability of IRmax has been proven in hot, cold, wet and saline environments, making it ideal for offshore.
IRmax's unique Stay Clir optical components are treated with a highly durable coating that completely prevents faults due to condensation. As IRmax contains no components for artificially heating optical surfaces, power consumption is dramatically reduced, requiring only 1W of power..

Txgard-IS+

TXgard-IS+ is a Intrinsically Safe (I.S.) toxic and oxygen gas detector with local LCD display. A very wide choice of sensors are available for use in a variety of applications. TXgard-IS+ is ATEX certified for use in Zone 0,1 or 2 hazardous areas and also UL and cUL certified for use in Division 1 or 2 hazardous areas.

Calibration can be performed locally without the need for hot work permits - minimises operational down-time
Local display and buttons enable calibration without opening the junction box

Extensive range of electrochemical sensors for toxic gases and oxygen

2 wire format

TXgard Plus

TXgard Plus is a flameproof (Ex d), ATEX and UL certified toxic or oxygen gas detector with local LCD display. A choice of sensors are available enabling use in a wide range of applications, including water treatment, oil and gas exploration, chemical plants and steel production.

Calibration can be performed locally without the need for hot work permits - minimises operational down-time
Local display and buttons enable calibration without opening the junction box

Carbon Monoxide, Hydrogen Sulphide and Oxygen range of electrochemical sensors available

3 wire format

Flamgard Plus

A Flamgard Plus is a Flameproof (Exd) flammable gas detector which uses poison-resistant pellistors to detect explosive levels of hydrocarbons, hydrogen and other flammable gases and vapours, including aviation fuel and leaded petrol vapourswith display

4-20mA current sink or source - works with a wide selection of control panels
3 wire format
Optional relays for alarm and fault - can be used for switching local alarms.

Choice of catalytic beads for a wide selection of flammable gases and vapours - gas detector tailored to your requirements
