When selecting for commercial-use truck reefer units for chillers, there are plenty of decisions to make. In our previously-published post named as “how to choose truck refrigeration units?”, Guchen Thermo introduced several most commonly-applied installation models of transport refrigeration systems (van & truck). Customers are more likely to purchase nose-mounted unit when it comes to select an easy-installation TRU for refrigerated trucks.

◆ Undermount truck unit is recommended if you want to facilitate maintenance repair and operations. Generally speaking, the higher the truck box stands above the cab, the more convenient it will be to install the vehicle with a nose-mounted refrigeration unit. But if the truck cab is too high to successfully fit a front-mount system, undermount truck unit will be a better alternative.
 
◆ This type of installation won’t affect the vehicle line. Undermount truck refrigeration units are available in a wide variety of designs - multi-temperature design or electric standby. It is a relatively compact unit mounted under the chassis of the refrigerated vehicles.
