Careers at Kerstner

Here you don’t build theories. You build refrigerated vehicles.

Our workshop in Groß-Rohrheim, part of the Lamberet Group.

Why this work matters

When fresh goods arrive safely, real workshop craftsmanship is often behind it.

Kerstner vehicles work daily in food businesses, logistics, pharmaceuticals and catering. They reliably carry meat, dairy products, medicines and prepared meals, for example, at the correct temperature.

That makes the work tangible: the result is a vehicle that people need and that must perform every day out on the road.

Why Kerstner?

One factory, close collaboration and European backing.

Groß-Rohrheim locationWorkshop, warehouse and engineering work closely together. This makes coordination fast.
