AMS Equipment Safety | Crowcon Gas Detection
The distiller recently built a new innovation centre which is being used for the development of new whiskies. The new gas monitoring system was required for this building.
The primary target gases were ethanol (which is a by-product of whisky production) and carbon dioxide (which is a byproduct of the fermentation process).The distillery site presented several challenges. It was a noisy environment, included multiple ATEX zones, and had substantial potential for gas leaks.
In addition, Crowcon’s new gas monitoring system had to include sounders and beacons place at various points around the site. As well as the appropriate outputs from the control panel to alert staff to alarms.
Moreover, the distillery specified that their new gas detection system should protect employees, alert staff to any gas leaks and alert staff to any issues with process (for example, where a process may cause a gas leak).
Crowcon Gas Detection
More importantly, Crowcon focus on gas detection by understanding current and future market requirements and responding accordingly. Crowcon’s vision is to protect people and the environment from gas hazards by providing both single and multi gas monitors, enabling personal and larger-scale monitoring.
Crowcon operates globally through a network of regional offices and authorised channel partners. To support the Crowcon ethos, they take care to recruit the best talent and invest in people by providing opportunities to develop and learn.
T&D distribute Gas Detectors, Gas Monitors & Equipment (Portable & Fixed) for the monitoring of toxic and flammable gases in industrial and hazardous areas – this includes Crowcon.
T&D sales engineers can specify safe gas detection equipment for any industrial application; Â including ATEX & IECEx certified gas detectors for use in Zone 1 and Zone 2 hazardous areas in the oil, gas and petrochem industries.
To create the new system, AMS used an innovative combination of two Crowcon products. To manage the presence of carbon dioxide they used the XGard IR, an explosion-proof gas detector with a dual-wavelength infrared sensor that gives highly reliable detection of hazardous gases and vapours.
Xgard IR offers the many advantages of infrared sensor technology in a rugged and versatile package. It provides fail-safe sensor technology, is immune to poisoning and damage by over-gasing, and is sensitive and quickly responsive.
Meanwhile, the ethanol is monitored via the XGard Bright with MPS™ sensor which, thanks to the use of MPS™ technology, simultaneously monitors multiple gases with TrueLEL™ accuracy. The XGard Bright with MPS™ requires no calibration for 5 years whilst being coupled with an extended-life battery, greatly reduces associated disruption and downtime, leaving the distillery free to develop new whiskies in peace.
Crowcon Xgard Bright
The flameproof (Exd) detector is housed within the high-grade aluminium alloy or 316 stainless steel enclosure. Certifications include gas and dust approvals for ATEX and IECEX with UL gas certification in progress.
Furthermore, the Xgard Bright is a versatile platform offering flammable and toxic gas detection and oxygen monitoring, while providing ease of operation and reduced installation costs.
However, the Xgard Bright comes with an Alarm and Fault relay as standard as well as optional HART communications.
Lowering the cost of installation, the 4-wire addressable implementation drastically reduces cabling requirements. Likewise the large OLED display allows users to easily work with Xgard Bright whilst installing, calibrating and routine maintenance without the need to open the housing.

Roof & Gutter Heating System Solutions
Thorne & Derrick | Eltherm Trace Heating Cables & Systems | Designs & Surveys | Competitive Prices | Safe & Hazardous AreasÂ
Snow & Ice Melting
Roof and gutter de-icing trace heating cables prevent ice dam formation on roofs ensuring safe free flowing of melt water through gutters and downspouts to ground level. The heating cables prevent ice dams from forming on inclined roofs, in gutters and in downspouts. Please note roof de-icing cables should not be used as a general snow-melting system to clear roofs from ice and snow build-up in winter.
▶ Thorne & Derrick together with Eltherm can provide expert technical support and design services for roof and gutter trace heating systems – the length of the roofline does not determine length of heating cables required. Roof design, roof size, gutter and downspout locations and number of sides of a typical, peaked roof to be protected from snow and ice needed to be considered. Please contact us today to discuss your specific application in more detail.
Using heat tracing cable maintains a flow path for the water and prevents gutters overflowing and water seeping back into the building. Melt water which cannot freely drain away will form pools which in turn can penetrate seams and joints in gutters and flat roofs causing serious damage to the internal building fabric and contents.
A leaking gutter or roof can cause extensive structural damage within buildings. Heat tracing cables create a flow path for the water allowing it to drain away correctly.
In some cases, the load bearing weight of any snow accumulation is the primary concern as the additional weight can negatively affect the structural integrity of the building.
Gutters with heating cables can prevent roof avalanches, which is crucial for public buildings.
These include:
The heating cables are installed over unheated roof sections, usually the roof area above the overhang ensuring water flowing onto the unheated roof area will be able to flow safely to the ground. Melt water which cannot adequately drain away from the roof will form pools which in turn can penetrate seams and joints in gutters and flat roofs.
Installing heating cable in roof valleys, gutters and downspouts as per the image below establishes ice-free flow pathways for water to drain completely from the eaves and gutter. With a maximum temperature of 65 °C, there is no risk to plastic pipes, gutters and conduits.
In the worst-case scenario, if drainage is impeded in the downspout, it can burst, resulting in significant damage. To safeguard gutters, box gutters, downspouts, or sloping roofs from ice-related harm and ensure maximum safety, an Eltherm gutter heating presents an ideal solution.
Low Maintenance, Maximum Flexibility
Self-regulating heating cables are known for their reliability and minimal maintenance requirements, whilst also offering a long service life. Specifically designed for gutter heating, we utilise low-temperature heating cables like ELSR-LS or ELSR-N.
These self-regulating heating cables offer the flexibility to be operated with or without a temperature controller. While they automatically regulate their temperature, they cannot be set to a specific temperature. If a constant temperature is required, a temperature controller must be used.
What Do I Have To Take Into Account?
When it comes to installing heating cables on your roof and gutter systems, attention to detail is key to ensuring optimal performance and safety, Using these tips:
Installation Guide for Roof and Gutter Trace Heating
By following these steps, you can ensure that your gutter heating system operates efficiently, providing protection against ice buildup and potential damage during the winter months.
Thorne & Derrick, the UK’s leading Specialist Distributor of Electrical Process & Trace Heating Solutions, last year announced they had entered into a Strategic Partnership with Eltherm UK Ltd, the subsidiary of the Eltherm Group, a world-class manufacturer of Heat Tracing Cables & Systems for the commercial, industrial and hazardous area industries.
Thorne & Derrick provide a complete portfolio of Electric Process & Trace Heating Solutions for Industrial, Hazardous Area & Explosive Atmospheres,
DIN EN 60079-30-1
Electrical resistance trace heaters are used for heating fittings, conduits and tanks. Resistance trace heating are understood as meaning, according to the standard DIN EN 60079-30-1, the use of electrical trace heaters, trace heater pads or trace heater panels and auxiliary components applied from outside, in order to increase or maintain the temperature of the contents of pipe networks, tanks and associated equipment.
A trace heating cable produces and transmits heat based on Ohm’s law. The field of application ranges from frost protection to the prevention of condensation in gas analysis and to the heating of media for production and processing.
Ohm’s Law states that electric current is proportional to voltage and inversely proportional to resistance.
This is where electrical resistance heaters are more suitable than the previously frequently used vapour- operated trace heaters as they work extremely economically and more accurately in terms of temperature. Electrical resistance trace heating manufactured by Eltherm and distributed by Thorne & Derrick are often the basis for a optimum process sequence and have become indispensable in many areas and applications in todays industry.
Self-Limiting Heating Cable
When electrical resistance heaters are used in hazardous area apart from the technical component, the basic requirements and safety specifications of the corresponding Ex standards must also be observed.
However not every resistance heater is suitable or admissible for use in hazardous areas, but each one must always be carefully selected and considered from two sides during planning and construction. On the other hand a basic feature of the product is suitability application in the process compared to the inclusion of type specific properties on the heater- when operated in accordance with its intended use and during malfunction.
If the application requires a higher heating power, making a stabilised application no longer possible, due to the resulting higher operating temperature and without an additional temperature limiting device. The critical limiting temperature will be exceeded in normal operation as well as in case of error or becoming a source of danger in the hazardous area.
These requirements and safety relevant protective measures must be taken into account when planning to use ATEX trace heating for operation according to its intended use in hazardous areas.
System-certified analyser heated hose
The trace heating system is designed so the sheath temperature of the trace heater meets with the standard conditions and is limited to the temperature classification (T1-T6)Â or ignition temperature.
This should also require certain safety margins from the maximum operating temperature, which is minus 5K at the temperatures below or equal to 200°C and minus 10Kelvin at temperatures above 200°C.
These requirements can be satisfied either by means of a stabilised design or by using a temperature monitoring system at the resistance heater.
