Important

The refrigeration unit is never considered in isolation.

Kerstner assesses the refrigeration unit, interior insulation, base vehicle, payload and temperature range together. This creates a refrigeration solution that works in daily use, rather than a purely theoretical unit selection.

With electric refrigeration, the distinction remains clear: the refrigeration unit can operate electrically even if the vehicle itself is not battery-electric.

Roof-mounted Thermo King E200-20 The Thermo King E-200 is a fully electric refrigeration unit designed for vans. Its variable-speed compressor precisely controls the cargo area temperature, reduces energy consumption, and improves reliability. A specially developed inverter ensures the unit delivers consistent power independently of the vehicle. This is especially advantageous in delivery traffic with frequent stops. The system also operates quietly enough to meet noise protection regulations in urban centers. The DSR-IV controller features intelligent energy management, synchronizing power supply with demand. A smart charging system manages multiple power sources, including an additional battery unit. Integrated telematics allow tracking the location and status of each unit in the fleet. Defrosting is automatic using hot gas. Depending on the cargo area, evaporators ES100N, ES150, and ES200 are available. The Thermo King E200-20 cools during driving or vehicle operation and at rest via the 230V socket.

The temperature is precisely controlled to 1 °C, with standby cooling possible via mains power. The Thermo King V-400X MAX from the VX series offers high cooling capacity and precise temperature control. Using the control panel in the driver's cab, you regulate the load space temperature in single and multi-temperature operation to an accuracy of 1 °C. Because the unit operates without its own engine, it produces no exhaust emissions and runs especially quietly. This is an advantage for deliveries in inner cities and residential areas. The unit weighs only 75 kg (model 50) and is compactly designed, leaving more payload capacity for goods. The aerodynamic design is optimized for daily use. - Cooling capacity while driving: 4.082 W at 0 °C / 2.237 W at -20 °C - Cooling capacity on mains power: 3.026 W at 0 °C / 1.496 W at -20 °C - Air volume: 1.990 m³/h - Temperature control: single and multi-temperature, accurate to 1 °C - Operation: control panel in the driver's cab Roof-mounted Thermo King V400X Max 50 The Thermo King V-400X MAX from the VX series is driven by the vehicle engine and requires no separate motor. This results in quiet, low-vibration operation without its own exhaust emissions, making it ideal for deliveries in inner cities and environmental zones, including at night. With a cooling capacity of 4.082 W at 0 °C and 2.240 W at −20 °C, the unit is suitable for both fresh delivery and deep-freeze transport. The cab controller Direct Smart Reefer (DSR III) maintains the cargo area temperature within ±1 °C. It displays malfunctions via clear alarm codes and automatically reminds of scheduled maintenance. The 50 version offers two additional features: through electric standby, the unit continues cooling when the engine is off using an external power supply at 400 V. The heating function protects the cargo in winter from excessively low temperatures. The lightweight, aerodynamic housing preserves payload capacity. The condenser can be mounted on the front wall, on the roof, or recessed in the roof. Defrost is automatic using hot gas. Optional features include door switches, a DIN adapter for controller installation in the radio slot, telematics via BlueBox Lite, and data loggers compliant with EN 12830. The max 50 version offers cooling while driving, cooling while stationary via external 400V power supply, as well as a heating function with 3.564W during driving and 1841W when connected to mains.
