A new parking cooler should be evaluated as an installed cab system. Cooling output, battery demand, roof fit and service access must work together. A launch specification alone cannot establish whether a unit will keep your drivers comfortable throughout their actual rest period.

What was announced?

On 11 May 2026, Eberspächer announced the Cooltronic 2000 G3 Hatch and 1600 G3 Hatch, covering 12- and 24-volt applications and advertised cooling capacities up to 2,000 and 1,600 watts respectively. The announcement describes engine-independent operation and inverter technology. These are manufacturer statements, not results from a Vethy comparison test.

Translate the announcement into four purchasing questions

  1. Which exact configuration is being quoted? Ask for the model code, operating voltage, installation kit and current manual. A product-family description may combine several versions.
  2. What electrical energy does the installed system consume? Request input measurements over a complete rest period, with ambient temperature, cabin setpoint and operating mode recorded. Cooling capacity is heat removal, not electrical consumption.
  3. What happens before the battery is depleted? Confirm the protection behavior, restart procedure and interaction with the vehicle's battery management. A protective cutoff can preserve an electrical reserve while still ending cooling earlier than the driver expects.
  4. Can the installation be serviced? Check access to filters, connectors, drains and replaceable components. A compact housing does not automatically mean a quick repair.

Use a repeatable acceptance run

Choose a representative vehicle and document its roof structure, battery configuration and starting state of charge. Measure temperature near the sleeping position as well as near the outlet. Log electrical energy and the times when operating modes change. Keep the doors and curtains in the same positions across comparison runs.

Decide the pass criteria before testing: the required comfort period, permitted noise at the bunk, allowable interruptions and charging recovery before the next shift. Repeat the test under the most demanding normal route conditions, rather than relying only on a shaded demonstration.

How should buyers compare alternatives?

Compare complete installed packages with equivalent test conditions and written service commitments. A lower equipment quote may require additional batteries or mounting work; a higher cooling rating may be unnecessary for a smaller insulated cab. The useful outcome is a documented fit for the route, not a winner selected from headline numbers.

Next step

Compare the available configurations in the Vethy product catalog, then request the current model-specific documentation before selecting a unit.
