Tank Heating in Gismarvik
Steatite-based heating elements ensure efficient tank heating and a long service life.
Client: Velde Asfalt AS
Period: 2024
Delivery: Temperature Maintenance - Bitumen
Application Areas: Industrial - Tank Heating
The challenge
Bitumen is highly temperature-sensitive. If the temperature is too low, viscosity increases, raising the risk of operational disruptions and blockages. Prolonged exposure to excessively high temperatures, on the other hand, can lead to oxidation and ageing. The tanks must therefore maintain a stable temperature to ensure good pumpability and safe operation, even when ambient temperatures fall well below freezing.
The solution
Velde Asfalt AS, through the Danish tank manufacturer Kronjysk Industri Service, selected Proxll as the supplier of the heating system for the facility in Gismarvik.
Proxll supplied a complete electrical heating system for three new bitumen storage tanks, including engineering and sizing, manufacturing, supply, installation, testing and commissioning. The solution was developed by Proxll specifically for storing bitumen at temperatures of 160–170 °C under Nordic climate conditions.
Scope of delivery included:
- Engineering and thermal design of the system
- Supply of a total of 18 specially developed steatite-based heating elements (cartridge heaters) for high operating temperatures, including junction boxes
- Temperature sensors and safety equipment
- Control cabinets and temperature control system
- Documentation, testing and final inspection
- On-site installation and commissioning support
The result
Proxll’s solution for Velde Asfalt’s bitumen tanks in Gismarvik ensures stable storage conditions for bitumen throughout the year. This reduces the risk of product degradation, operational disruptions and unnecessary energy consumption, while ensuring stable and efficient asphalt production. As a result, Velde Asfalt has a robust and durable solution that contributes to:
✓ Increased operational reliability – Ensures stable asphalt production.
✓ Improved monitoring – The control system provides alarms and early warnings of potential faults or hazards.
✓ Lower maintenance costs – The heating system is virtually maintenance-free.
✓ Energy-efficient operation – Optimised energy consumption based on actual heating requirements at low ambient temperatures.
With this solution, Velde Asfalt AS has achieved consistent and reliable heating of its storage tanks, helping to maintain product quality and efficient operation under varying climatic conditions. Proxll’s steatite-based tank heating systems are designed for long service life, energy-efficient operation, and high reliability in demanding industrial environments.
