Refrigeration units made in-house

Kerstner CoolJet. Refrigeration that belongs in your vehicle.

Efficient cooling, perfectly matched insulation and a design that impresses down to the last detail: Kerstner CoolJet brings together everything that makes a thoughtfully engineered refrigerated vehicle.

Refrigeration and insulation from a single source

Made by us. Matched to your vehicle.

We develop and manufacture our CoolJet refrigeration units ourselves. This allows us to tailor cooling capacity, energy demand and integration specifically to our insulation and the way each vehicle is used. The result is a complete system whose components work together optimally. That is why almost every refrigerated vehicle we equip features our own refrigeration technology.

Attractive on the outside.
Efficient on the road.

Our roof-mounted units blend harmoniously with the vehicle’s contours. Their aerodynamic design combines a high-quality appearance with carefully engineered airflow and can help reduce fuel or energy consumption while driving.

Thoughtfully designed inside.
Easy to clean.

Inside the load compartment, the evaporator and its cover are designed to work together so that no refrigerant hoses are visible. This creates an uncluttered interior and makes thorough cleaning easier. A decisive advantage wherever hygiene is a daily requirement.

Integrated into the cab.
Like a factory fit.

We also pay attention to every detail of the controls. Depending on the vehicle model and dashboard, we integrate the controls precisely into the cockpit. For refrigeration technology that feels a natural part of your vehicle.

Clear terminology

Electric refrigeration does not automatically mean an electric vehicle.

Electric refrigeration

Describes the type of Kerstner refrigeration unit. The base vehicle may still be diesel, petrol or battery-electric.

Belt drive

Describes a directly driven refrigeration unit for high capacity requirements, chilled and frozen goods transport.

BEV powertrain

Describes only the vehicle’s powertrain. The badge applies only to vans with a battery-electric base vehicle.

The table provides guidance. The specific choice is always assessed against vehicle platform, payload, temperature range and route profile.

Refrigeration unit plus interior insulation

The strength lies in the system, not the unit alone.

Refrigeration technology for vans and refrigerated bodies Interior insulation, refrigeration and practical equipment from a single source Electric refrigeration for suitable van applications Designed for chilled and frozen goods transport Strong everyday practicality for fleets and food businesses Clear technical information for advice and tenders

Test reports & supporting documents

The right refrigeration technology is assessed for each project.

Test reports and ATP-related supporting documents must match the specific vehicle and conversion configuration. Kerstner therefore checks which documents are actually relevant to the vehicle platform, temperature range and application in each project.

Frequently asked questions

Questions and answers.

Is CoolJet a Kerstner product?

CoolJet is the Kerstner product range for refrigeration units in the van segment. The suitable series is selected for each project.

When is a vehicle truly a BEV?

Only when the base vehicle is battery-electric. An electric refrigeration unit alone does not make a vehicle a BEV.

Can every CoolJet be combined with every van?

No. The vehicle platform, installation space, temperature range, payload and supporting documents must be checked for the specific project.
