What is a changeover?

A changeover is when we remove the tank body from an existing chassis and mount it to a different new or used chassis. Changeovers vary in complexity based on the unit and the work needed. We offer a variety of services including tank testing, air emergency valve conversions, electronic register conversions, complete equipment overhaul, etc.


Why is Seneca Tank the best choice for changeover work?

Seneca Tank prides itself in being an industry leader in changeovers. With over 30 years of experience our staff is dedicated to providing top notch service from start to finish. A change over can be as simple as removing the tank and mounting on to a new chassis to a full overhaul of the tank and equipment, Seneca Tank is the best.


What are the benefits of doing a changeover compared to a trade-in?

As a truck get older the costs of maintenance rises significantly, however the tank body can stay in the field a while longer. Our changeover program makes the most out of your initial investment. You will get the same professional service you have come to expect from Seneca Tank, while also giving new life to your old tank with a fresh chassis. We also offer a variety of services including tank testing, air emergency valve conversions, electronic register conversions, complete equipment install, etc, to insure that the tank of yesterday meets your needs of today.
