Reliability in Extreme Weather Conditions

Our bitumen tanks are among the most reliable in the industry. We prevent downtime by selecting high-quality and proven durable components. The tanks are designed to be easily adaptable for cost-effective transport of different products.

Our equipment is engineered for the harsh weather conditions of the Nordic region. The transport tanks perform at full capacity even at -40°C and are made from corrosion-resistant materials. Maintenance has also been a key focus in the design—component replacements and servicing are made easy with our specially designed maintenance hatches.

Safety, Performance, and Continuous Product Development

We have invested heavily in the safety features of our transport tanks. One of the most important is the automatic pressure equalization system, which ensures that the tank is not damaged even if the appropriate hatches are accidentally left closed during unloading.
Additionally, we have developed a heating system for our tanks, now available with remote control functionality. To prevent pipe system failures, we have introduced expansion joints. To prevent pipeline breakage, we have developed piping expansion joints.

For critical operating components such as pipeline valves, we always choose the best quality available. We are also constantly working to lighten the tanks so that our customers can increase their payload.
