4000N is the largest of our models that have a temperature range from 2°C to 10°C.
It can be installed at a big trailer of max. 32 m³ or an insulated 20-ft-long container.

Our units consist of two parts: the condenser on the outside and the evaporator on the inside of the trailer. Both parts are mounted on an insulating core and form an easy to install plug-and-play unit. We use the same casing for all our refrigeration units standardising the size of the cutout for all trailers. The casing is made of power coated steel sheet including a shapely front hood made of ABS plastic. An electronic controller monitors and regulates the operating temperature. Automatic periodic defrosting is provided by a programmable electronic thermostat and an electronic thawing-off device. Behind the lockable operating cover you will find a control switch and a light switch for the interior lighting of the refrigeration trailer.
