More years of use for the equipment

The potential lifespan of tanks is long. KAR-Lehtonen helps to renovate and renew the existing equipment to meet the changing requirements of operations. Even a tank, which is decades old, can be refurbished to almost new with expert modifications, saving
the customer’s resources. This is also practical for the customer from the point of view of saving time, as there is no need to relearn how to use the equipment from the beginning.

The modification of a tank will also help to adapt the equipment to meet new requirements, for example, when the Traffic and ADR Act will be updated. In this case, by renewing the existing equipment, the customer can take advantage of the increasing payload made possible by law, for example.

The possibility of changing the platform also increases the service life and provides a higher payload for the equipment. We handle platform changes with professionalism, and we are also happy to offer consulting assistance in selecting the optimal platform.

More versatility – more return

We know that our customers’ usage needs vary over time. That’s why we’re helping to make optimal use of old equipment with modifications when needs change. We succeed in changing the volume of tanks as well as increasing the number of compartments, which means that the same tank can be used for the simultaneous transport of several products.

If necessary, we will help to modify the tank for different products when, for example, new types of fuels are introduced to the market. The trailer tank can also be shortened to a vehicle tank and vice versa.

Modifications and accessories can be used to make the equipment more modern and efficient – for example, to increase the efficiency of pumps, speed up operation, and improve operational safety.

The goal of modifications is always to optimize the customer’s transport capacity so that the equipment serves different needs and achieves a better profit ratio.

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.
