Frost ProtectionÂ
Rail traffic has to run smoothly even in cold and snowy winters. With rail transport it is not only about getting a lot of people to their destinations on time but also ensuring passengers safety.
Freeze prevention on tracks and switch points is imperative to keep them free from ice so trains can safely operate on track and on time. A reliable, energy efficient electrical trace heating system with intelligent control achieves just that as well as providing several technical and economic advantages such as:
Thorne & Derrick, the UK’s leading Specialist Distributor of Electrical Process & Trace Heating Solutions, earlier this year announced they have 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 | Stockists & Key UK Distributor
Uploaded by Natalie Lundie | Supply Chain: Marketing Lead at Thorne & Derrick
Thorne & Derrick, the UK Specialist Distributor of Wolf Safety Lighting were approached by a major player in the global aviation industry. The company wanted to improve their shot blasting maintenance turnaround time of their fleet of Airbus’s that were located in Spain.
The client required a hands free, temporary ATEX lighting solution so staff could could carry out inspection, maintenance and repair safely inside the potentially explosive atmosphere of the aircrafts’ fuel tanks.
Shot Blasting In The Aviation IndustryÂ
Shot blasting is a vital step in aircraft maintenance and repair, as it helps to remove corrosion, paint, and other surface contaminants that can affect the performance and safety of aircraft components as well as prolonging the life of assets.
In addition, the lighting fixtures for the aviation industry are designed to be resistant to dust, vibration, and shock, ensuring that they can withstand the rigors of the shot blasting process.
In this instance a solution was needed which would supply much higher quality, brighter lighting within the fuel tanks and would leave operators’ hands free to concentrate on the maintenance and shot blasting work.
The light source must have the correct ATEX certification to counter the potential risk of explosion and take into account the physical challenges of the aircraft’s structure, including the narrow entrances and confined nature of the tanks themselves.
Wolf ATEX Lighting To Safely Illuminate The Interior Of Boeing 737 Fuel Tanks
Thorne & Derrick quickly identified that the client required a powerful, safe and cost effective ATEX and IECEx certified lighting solution for the shot blasting and recommended the LinkEx™ Tank Lighting Kits by Wolf. These ATEX Tank Lighting Kits are designed for aircraft fuel tanks, ensuring safe and efficient refuelling operations.
The kits include four sealed LED lights and a linkable power supply, which is mounted outside the aircraft. They are rugged enough to handle the harsh conditions of aircraft refuelling while remaining lightweight and easy to install.
By providing this temporary ATEX lighting solution, Thorne & Derrick were able to help the client improve safety and efficiency during their aircraft maintenance activities, while also ensuring regulatory compliance in a potentially hazardous working environment.
T&D reacted quickly to the client’s original enquiry that came in via our website. Our technical sales team called the client to discuss their requirements in more detail. Within two hours of the initial enquiry we had received an order for one unit as a trial, they subsequently ordered another fitting the week after.
This demonstrates our commitment and ability to provide efficient and effective service to our customers. Our dedicated sales team are always ready to respond promptly to any queries and provide technical expert advice to ensure our customers get the best products and services.
At Thorne & Derrick, we understand that harsh industrial or hazardous environments demand reliable & correctly certified equipment.

The aviation sector plays a critical role in the economy by facilitating travel, trade, and commerce. The sector also has a significant impact on the environment, and efforts are being made to reduce emissions and minimise its carbon footprint. The aviation sector is constantly evolving, with advancements in technology and changes in regulations and global events influencing its direction and growth.
Some common areas where explosive atmospheres can be present in the aviation industry include fuel storage areas, fuel transfer areas, aircraft maintenance areas, and aircraft hangars. In these areas, any spark, flame, or electrical discharge can potentially ignite the flammable materials present, leading to a catastrophic explosion.
To manage the risk of explosion, various safety measures can be implemented, including:

Heated Hoses/Sample Lines Stocked and Distributed by Thorne & Derrick
Heated hoses, also known as heated sample lines, are specialised hoses that are designed to maintain a consistent temperature. They are typically used in applications where the temperature of the liquid or gas being transported needs to be maintained throughout the length of the hose, and can be used in both industrial and hazardous areas (ATEX).
These hoses are often used in industries such as food and beverage production, chemical processing, and oil and gas extraction. Heated hoses typically have an insulated layer between the inner and outer layers of the hose that houses a heating element. The heating element is designed to raise the temperature of the liquid or gas passing through the hose, and the insulation helps to contain that heat.
Some heated hoses are designed to be self-regulating, meaning that the heating element automatically adjusts its output based on the temperature of the liquid or gas being transported. Others have a set temperature that is regulated by a thermostat. Overall, heated hoses offer a reliable and efficient way to transport liquids and gases that need to be maintained at a specific temperature.
Following a recent strategic partnership agreement with Eltherm, Thorne & Derrick hold extensive UK stocks for a range of heating products including heated hoses. Eltherm is one of the leading suppliers of heated hoses / flexible heated lines, ensuring the transport of liquid and gaseous media without loss of temperature.
Eltherm heated hose products are available with different temperature ranges up to 100 °C, 200 °C, 250 °C or 450 °C.
➡️ For the heating and process temperature maintenance of pipework and mechanical services Thorne & Derrick stock and supply a complete range of heat trace cables and trace heating systems.
Flexible transport without temperature loss of liquids and gases is very important, therefore Eltherm offer various possibilities to heat containers, pipes, tanks or vessels. These heating products also offer increased safety for personnel, as there is less need for manual handling of hot or cold fluids; along with energy efficiency as heating is localised to the hose and does not require large heating systems
Eltherm’s heated hoses are versatile and can be used in various applications, such as transporting liquids and gases, melting solids, freeze protection, and process heating. The hoses are available in different materials and sizes, are easy to install and maintain, and are energy-efficient and safe. Each system is tailor-made with high flexibility and load capacity.
Whether in use on moving production unit components, in mobile applications (e.g. gas analysis) or for balancing offset piping, heated hoses are available for the specific application.
In partnership with Thorne & Derrick, Eltherm heated hoses are individually designed and produced according to customer specifications.
Industrial and Hazardous Area Heated hoses always consists of an inner liner, temperature sensor, heating conductor, insulation, outer jacket and an end cap. The heated hose can then be operated via a controller by recieving information from the temperature sensor. Fittings are installed depending on the application, the operating pressure and temperature.
The outer jacket of the equipment can also be constructed from a variety of metals according to requirements. For example an outer jacket made of stainless steel will be more mechanically robust and suitable for higher temperatures; compared to a silicone outer jacket which is washable and designed for more flexibility and smaller bending radius. For high-pressure applications, fluoropolymer and polyamide materials can be used.
Heated Hoses From Eltherm
There are a variety of applications, where a heated sample line would be required. For example, they are often used in chocolate production to maintain consistent temperatures throughout the process. The hoses can be used to transport melted chocolate from the heating tank to the production line without the chocolate solidifying or cooling too quickly. This ensures that the chocolate remains liquid and easy to work with, which is crucial for creating high-quality chocolate products.
ATEX Heated Hoses are also essential to the oil and gas industry because they are used to transport viscous chemicals and materials that solidify at lower temperatures. These materials include crude oil, asphalt, and bitumen. Heated hoses help maintain the viscosity of these materials by heating them to the required temperature, ensuring that they remain fluid and pumpable.
Heated hoses must be able to withstand high temperatures and pressure, making them an essential tool in drilling, exploration, and refining operations. They also provide safety benefits by preventing the solidification of materials that could cause blockages, leaks, or other hazardous situations.
