Fast, reliable flame detection
Ideal for use in the extreme environments of oil, gas and petrochemicals, Draeger Flame Detectors ensure fast, reliable detection with high sensitivity, no fail to danger modes and no false alarms
Ideal for use in extreme environments, particularly those found in the oil, gas and petrochemicals industries, Draeger Flame Detectors ensure fast, reliable detection with high sensitivity, no fail to danger modes and no false alarms. Offering ultra-violet (UV) and infra-red (IR), as well as combination (UVIR) detection of hydrocarbon and non-hydrocarbon based fires, the range is easy to use and is ATEX and FM certified and SIL rated. Designed to detect organic based fires involving hydrocarbon fuels and vapours, the Draeger Flame 1300 is an IR Flame Detector for use in the oil and gas industry.
For those high speed applications where UV detection is required, the Flame 1700 can be used to detect organic as well as non-organic based fires such as hydrogen and metals.
The Draeger Flame 2300 is a combined UVIR that requires both IR and UV sensors to be alarmed before the detector itself will output an alarm condition.
Simple to install within a stainless steel mounting bracket, the detector can be rotated to ensure optimum positioning in relation to the potential fire source.
In addition to a 4 to 20mA output and three relays, an optional RS485 output can also be multi-dropped to a central location.
This provides a number of options for monitoring as well as triggering the necessary control action should a fire be detected.
To eliminate the risk of faults, the detector electronics and optics are checked automatically and, as and when required, can be triggered manually.
A tri-coloured LED provides a straightforward status indication with green indicating normal operation, yellow highlighting a fault and red signalling the presence of flame.
With an anticipated longevity of greater than 15 years, this innovative range of Flame Detectors combines flexibility in use with advanced design features that ensure reliability and provide excellent immunity to potential false alarm sources.

Draeger saves time and effort over SIL compliance
The need for safe system design is placing more and more focus on Safety Integrity Level (SIL) Standards: an innovative approach by Draeger Safety is making SIL compliance easier
The need for safe system design is placing more and more focus on Safety Integrity Level (SIL) Standards. This is particularly true in any application where there is a need to constantly monitor and detect explosive or toxic gases and vapours, as well as oxygen deficiency and/or enrichment. However, an innovative approach by Draeger Safety is not only making SIL compliance easier, but it is also saving organisations both time and effort in meeting the requirements.
Whilst some organisations have taken the individual component route to SIL compliance, Draeger has adopted a complete system approach utilising REGARD Controllers.
Doug Longstaff, Product/Technical Operations Manager, explains, ‘Following extensive customer consultation and many hours of data checking we found that, whilst individual components may be verified against a SIL target, it counts for nothing unless the entire system has been verified’.
‘By offering a complete system approach, including installation as well as the controllers, cables, input and output devices and service and maintenance procedures, we are able to guarantee Life Cycle Safety reliability in accordance with SIL requirements for as long as the integrity of the system is maintained: For the first time, this means that SIL compliance can be achieved at, almost, the touch of a button’.
System integrity is essential.
For instance, should a user change the system parameters by, perhaps, performing service and maintenance at seven months instead of the recommended six, the probability of failure will have been changed and SIL will no longer be valid.
For this reason, Draeger supports each of its SIL installations with a set of comprehensive user notes that combine recommended guidelines with comments and examples to ensure that the ramifications of any changes are clearly understood.
Editors note: Otherwise known as BS EN 61508, SIL is the international standard for electrical, electronic and programmable electronic safety related systems.
It sets out the requirements for ensuring that systems are designed, implemented, operated and maintained to provide the required SIL level.

Toxic gas detector receives ATEX approval
The TS4000 Intelligent Toxic Gas Detector, suitable for a wide range of industrial gases plus oxygen deficiency alarm, has received ATEX Approval for use in potentially explosive environments
Offering protection against a wide range of hazardous industrial gases, as well as oxygen deficiency, the TS4000 Intelligent Toxic Gas Detector from General Monitors has received ATEX Approval for use in potentially explosive environments classified as EEx d mb IIC (-40C < Ta < +75C). The sophisticated design of the TS4000 Toxic Gas Detector offers many advanced features, including long distance remote mounting up to 2,000 feet, dual redundant Modbus communications, 8 Amp relays, three-digit display, 4-20mA output, and indication of remaining sensor life. All of the electronics are contained within an explosion-proof housing so that sensor information can be processed at the sensor site.
Additionally, the galvanically-isolated, intrinsically-safe design of the interface module supports sensor field replacement without special tools or hot work permits.
Easy to install, the TS4000 features one-person calibration and can virtually self-calibrate by activating a magnetic switch and applying gas.
Process engineers who need to protect people and equipment will find that the TS4000 Intelligent Gas Detector is ideal for chemical, oil/gas, wastewater and other hazardous environments.
Additional applications include public utilities, refineries, pharmaceuticals and food and beverage.
The TS4000 monitors a variety of toxic gases in the parts per million (ppm) range, including: ammonia, carbon monoxide, chlorine, chlorine dioxide, hydrogen chloride, hydrogen sulphide, nitric oxide, nitrogen dioxide, oxygen deficiency, ozone, and sulphur dioxide.
The system displays gas concentrations up to 500 ppm, fault codes for troubleshooting, prompts when calibration is needed, and provides complete status to the Control Room.
Additionally, the TS4000 simplifies operation and maintenance and reduces downtime by providing remaining sensor life indication.
The TS4000 utilises an intelligent microprocessor-based design in an explosion-proof housing.
This 24 VDC-powered toxic gas detector is comprised of a base unit, sensor housing with interface module and electrochemical sensor.
The interface module processes information at the sensor site and communicates detected gas values to the base unit for data control and display.
By combining explosion-proof certification with intrinsically safe inputs, the TS4000 provides high performance in hazardous locations.
It can also be used for general-purpose, non-hazardous applications.
Purging hydrocarbon vessels of flammable vapour
Emptying hydrocarbon storage tanks, reactors, pipelines or other vessels is dangerous because there is a high risk of creating an explosive mixture if the purging operation is not managed correctly
Emptying hydrocarbon storage tanks, reactors, pipelines or other vessels is dangerous because there is a high risk of creating an explosive mixture if the purging operation is not managed correctly. Vessels have to be purged with nitrogen to reduce the hydrocarbon content to below the lower explosive limit (LEL) before air can be allowed into the enclosure, but many gas detectors are not well equipped to measure hydrocarbons at this low level and are prone to burn-out if exposed to higher levels. The infrared technology in the Crowcon Triple Plus+IR has been specially designed for this application.
With Triple Plus+IR, the purge vent gas is monitored to determine when there is less than 100% LEL equivalent flammable gas concentration.
The advantage of using a monitor (rather than an estimated time-lapse) is that the costly nitrogen purging can be stopped as soon as it is safe, with no need to guess the time or to run the purge longer than necessary.
The infrared detector in the Triple Plus+IR is a unique dual range infrared sensor for flammable hydrocarbons scaled with both 0-100% volume and 0-100% LEL ranges, with an automatic range switch between these.
Conventional meters are not sensitive enough for this job: if using only a 0-100% volume range, the required critical readings are in the bottom 5% of the scale and cannot be read with a high degree of confidence.
Purging is therefore usually continued until an effective zero reading is obtained, wasting nitrogen.
When using the Triple Plus+IR, however, as the hydrocarbon concentration falls below the equivalent 100% LEL concentration, the range switches from 0-100% volume to 0-100% LEL, so a clear and immediate visibility of a safe hydrocarbon level is given.
This allows the earliest possible termination of nitrogen flow and a switch to air.
Purge monitoring is also necessary in the reverse mode.
Before hydrocarbon can be re-introduced, a low oxygen level is essential (usually <2% by volume).
Nitrogen is therefore once again used to flush out the air, and the oxygen sensor fitted to the Triple Plus+IR is used to monitor the falling oxygen content of the exhaust line.
Once the oxygen content is low enough, the nitrogen flow can be stopped and the hydrocarbon re-introduced.
The monitor is then used to follow the refill process determining when full 100% hydrocarbon concentration is reached allowing venting to stop.
Conventional detectors frequently burn-out or become poisoned when exposed to these high concentration levels.
