The whole set unit adopts fully enclosed compressor as refrigeration units. So it has solved the problem of that current product in the market often needs to add refrigerant. The compressor adopts advanced DC frequency converting technique, so it can reduce the influence of the refrigeration units to the engine power of the vehicles. Meanwhile it can control the inner-space temperature more accurately.

The refrigeration system is not connected together with the engine, so it becomes more convenient for repairing the refrigeration units.

You can set any temperature as you want in the temperature range.
