Tailored to your needs – support throughout the lifecycle

We can provide a transport container tailored to your needs. We are happy to be involved already from the design phase, ensuring that the container is fully adapted to your operations – including the placement of the operating devices.

We manufacture tanks for platforms of all sizes and the size of the tank can be customized according to the customer’s wishes. From one cubic metre to more than 100 cubic metres.

It is important for us to support the customer throughout the lifecycle of the equipment. We offer our customers worry-free maintenance contracts and help with any questions. For example, in the seasonal operation of bitumen, we support the customer 24/7 throughout the busy summer season. In winter, we check and maintain our customers’ tanks, so they are ready for the new season.

We also provide the necessary spare parts for the tanks and thorough user training to ensure efficient and safe operation. As an additional service, we offer an extended 36-month warranty period for the equipment.

The maintenance documents for our tanks can always be found effortlessly in the cloud service. They can
also be easily accessed by the customer and maintenance companies using the QR code found on the tank.

Reliability even in harsh weather conditions

Our transport tanks are among the best in their field when it comes to reliability. We therefore want to prevent difficult downtime by investing in the selection of high-quality and durable components. The tanks are also manufactured for easy modification so that they can be adapted cost-effectively for transporting different products.

Our equipment is designed for the harshest weather conditions in the Nordic region. The transport tanks therefore operate at full capacity as low as -40 ° C and are made of corrosion-resistant materials. Serviceability has also been taken into account in the design – component replacement and maintenance are easy thanks to the service hatches we have developed.

Safety, performance, and continuous product development

We have invested heavily in the safety equipment of our tanks. One of the most important is the automatic pressure-relief system, which ensures that the tank is not damaged, even if someone forgot to open the appropriate hatches in the event of content unloading.

In addition, we have developed heating equipment for our tanks, which is also newly available with remote control. 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.

KAR-Lehtonen – referenssit

Meillä on ollut KAR-Lehtosen kanssa pitkäaikainen ja hyvä yhteistyö ja ollaan oltu tyytyväisiä heidän palveluun. Me ollaan tienpäällystyksessä Suomessa merkittävä tekijä ja ajetaan päällystykseen bitumia. Heillä on meidän toiminnan onnistumiseen ratkaiseva merkitys ja ovat sen täyttäneet. Lisäksi kehitystä on heillä tehty koko ajan parempaan suuntaan.

Kokemukseni on erittäin positiivinen KAR-Lehtosen toiminnasta. Kehitimme yrityksellemme uutta toimintaa ja siihen liittyen tilasin KAR-Lehtoselta alipaine/-imusäiliön ja meillä ei ole aiempaa kokemusta kyseisenlaisesta säiliöstä. Saimme yhteistyössä toteutettua juuri meille parhaan laitteen. KAR-Lehtonen oikeasti toteuttaa sen mitä asiakas haluaa ja pystyy myös asiakkaalle uusissa jutuissa antamaan neuvoa.

Vi har haft ett mycket gott samarbete med KAR-Lehtonen i över tjugo år. De har byggt ett antal olje-/ bitumen- och gassläp åt oss. De har även färdigställt alla våra tankbilar. Vi är väldigt nöjda med deras service.
