As the global energy industry pivots toward sustainable solutions, trace heating continues to play a vital role in supporting the infrastructure required for cleaner fuels like biodiesel.
The focus on the project was to ensure the reliable and energy-efficient transport of biodiesel through long pipelines and load arm systems—where precise temperature maintenance is critical.
Project: Bio Logistics Phase Il Coprocessing
Long Line Transportation Load Arm — Bio Diesel
Location: Castellon, Spain
Eltherm delivered a turnkey EPC solution, encompassing:
Engineering, Procurement, and Construction (EPC)
24 km of Eltherm ELSR and ELKM heat tracing cable
Custom-designed distribution panels
Monitoring and control systems for operational efficiency and safety
These systems ensure that biodiesel remains at optimal flow temperature, even over long distances and through varying ambient conditions—reducing downtime and preventing blockages
Year of Supply: 2021
Biodiesel has a higher pour point than conventional fuels, meaning it can solidify at lower temperatures if not properly managed. Heat tracing is essential in:
Maintaining flow temperature across extensive pipe runs
Preventing product gelling in cold environments
Ensuring system start up reliability
Enhancing energy efficiency in transportation processes

FAQ
What is the advantage of a heating jacket as opposed to a heating mat?
Heating jackets are always used when surfaces that extend over more than two levels need to be heated. As they are individually developed and manufactured for the individual surface to be heated, they fit perfectly and ensure an even heating.
Are Eltherm heating jackets easy to install?
As heating jackets have integrated thermal insulation and are custom-made, they are easy to fit and remove. This simplifies assembly, shortens installation times and reduces maintenance costs. As particularly high-quality materials are used, the heating jackets also have a long service life.
Efficient, Reliable Heating for Pressurised Gas Supply
Gas, one of the three fundamental states of matter, is highly compressible and typically stored in robust cylindrical or spherical containers. However, as gas is extracted—especially at high rates or low fill levels—bottle pressure can drop and condensation can form and freeze on the cylinder wall. This compromises performance, safety, and accuracy in gas supply systems.
Eltherm Gas Bottle Heaters, available from Thorne & Derrick, provide a reliable solution to these challenges by stabilising pressure, preventing freeze-up, and enabling complete cylinder discharge—essential when handling costly noble gases used in applications such as semiconductor manufacturing.
Stable Pressure During Withdrawal
As gas is withdrawn and vaporises, it cools the container. This can lead to freezing of the bottle and fittings, impairing gas flow. Eltherm heaters ensure consistent heat input to stabilise pressure and optimise flow rates.
Maximum Cylinder Utilisation
For expensive gases like argon or helium, it’s vital to empty cylinders fully. Without heating, residual gas may remain due to temperature-related inaccuracies in weight measurements. Eltherm heating mats maintain consistent temperatures, ensuring accurate readings from weighing systems and full use of gas contents.
Prevention of Condensation and Ice Formation
During continuous withdrawal, the bottle surface cools down, attracting and freezing ambient moisture. This is eliminated by applying controlled heat with an Eltherm heater.

Electrical heat tracing manufactured by Eltherm is employed to maintain exact temperatures when transporting temperature-sensitive chemicals in tank containers, SWAP containers, Road Tankers und IBCs (Intermediate Bulk Containers). Temperature maintenance is required for substances such as MDI, highly viscous industry materials, oils, resins, fat, coatings, bitumen, adhesives, foods and casting compounds
With its electric tank container heating systems, Eltherm has created an alternative to heating with water vapour, thermal oil and glycol. In comparison to water vapour or glycol heating systems, electrical heat tracing has a significantly lower weight. This offers the advantage of a greater loading capacity and therefore increased cost-effectiveness of the tank container.
As an engineering company – with their own production facilities – Eltherm provides comprehensive advice to freight forwarders and container manufacturers right from the planning phase. This cooperation ensures that the heat tracing system meets all transport and contract requirements. After all, it’s that simple and straightforward: Anyone who wants to claim the highest quality must be able to guarantee that high-quality products reach their destination without damage and remain in good condition throughout.
Benefits of the Eltherm Heat Tracing System:
Thanks to our specially developed installation technology and control system, which has been market-tested and continuously improved over decades, we can guarantee high temperature accuracy and consistent heating of the entire tank surface. To provide greater flexibility, several heating and control circuits can also be created for different filling levels.
Due to the very large contact surface, a generously dimensioned power reserve can be provided. This allows the loaded product to be heated up (within its physical limits). As an alternative to supplying power from the mains, the heating system can also be powered by generators. In addition, the product temperature can be fully documented over the duration of transport.
Along with the actual container, it is often necessary to heat attached components such as dome boxes, outlet valves and riser pipes. If required, customer-specific insulating sleeves for valves and ball valves can also be manufactured.
A special assembly technique for EHT on tank containers developed by Eltherm engineers plus reliable monitoring and control ensures uniform temperature accuracy across the entire tank surface. It is resistant to vibration impact and thus designed for reliable operation. Apart from the tank container itself, the EHT system takes account of outlets, riser pies, including insulating sleeves for valves and ball taps.
Technical Eltherm Advantages:
Our tank containers are used in potentially explosive atmospheres. Can your offer us a suitable heating system?
As the only supplier of heating solutions for tank containers with valid certificates and approvals in ATEX and IECEx, we can also offer you a safe solution to minimise your liability risks as an operator.
Is it sensible to heat a bottom outlet valve?
If a medium is to be transported that solidifies at ambient temperature, the outlet valve should be heated to ensure that the tank can be emptied without delay. We offer appropriate heating solutions for many standard valves on the market. Just get in contact with us!
We use riser pipes for loading and unloading. Why should these be heated?
To ensure that a product does not form a solid plug in the riser pipe during transport and storage in the tank container and thus make unloading more difficult, we offer appropriate riser pipe heating.
What types of energy supply are available?
In general, any electrical power supply can be used, from car batteries to overhead lines. Heating solutions with a power supply in the 400V 3-phase range have proven to be common and technically meaningful.
A heated hose plays an essential role in maintaining the temperature of fluids and gaseous media during the transfer in industries such as food processing, pharmaceuticals, chemicals, and automotive manufacturing. Whether it’s transporting viscous adhesives or temperature-sensitive liquids, precision heat control is vital to maintaining product integrity and operational efficiency.
However, industries that use heated hoses face their own unique challenges—ranging from environmental durability to regulatory compliance. Fortunately, companies like Eltherm have developed advanced solutions to overcome these hurdles.
In this article, we explore the six most common challenges in heated hose applications in process industries and how Thorne & Derrick together with Eltherm’s technology leads the way in solving them.
