How to choose Transport Refrigeration Units?

Transport Refrigeration Units (TRU) are refrigeration systems designed to refrigerate temperature-sensitive goods that are transported in various containers, including truck, vans, semi-truck trailers, shipping containers,etc.

How to choose Transport Refrigeration Units? This guide will cover the different types of Transport Refrigeration Unit and help you to choose the most suitable solution.

1. Van Refrigeration Unit

For refrigerated vans, we have engine driven and battery driven van refrigeration unit for choice.

Engine Driven van refrigeration unit means that it is driven by the vehicle engine, so if the engine stops, the unit stops cooling either. Besides, a compressor and compressor bracket will be needed to install near the engine.

Battery driven van refrigeration units have DC electrical compressor built-in the condenser, so there is no need to install mechanical compressor again, just connecting alternator or battery for power source is ok. 

When the engine is stopped, the dc electric refrigeration unit can continue to cool around 30 minutes (we can extend the duration by adding more batteries). If your vehicle does not have a space for additional compressor, DC Powered Electric Refrigeration Unit would be the best choice. 

Battery driven van refrigeration unit is also best choice for electric vans as the mileage of electric vehicles will not be reduced.

2.5 For Truck (35-60m³)  Diesel Engine Refrigeration Unit is recommended.

Diesel Engine Truck Refrigeration Unit has its own engine, which means even the vehicle engine stops or breaks down, the unit continues cooling without being interfered.

In 2019, we have launched our 3rd generation diesel engine reefer units. Compared to old models, the 3rd generation diesel units use original Yanmar engine: Yanmar 3TNV76

3 cylinders, lower noise help you reduce the clients complain when delivery goods in early morning, lower fuel consumption help you reducing your running cost, less vibration, no damage to the insulation body.

With extremely powerful cooling power, diesel Transport Refrigeration Unit performs exceptionally in 7.6-9.6m length cargo container.

3.For both van refrigeration and truck refrigeration unit, electric standby system are available.

Electric Standby system is also called plug-in electric standby. It uses an external electric source enabling the refrigeration system to operate normally when the vehicle diesel engine shuts off. It works with an additional electric compressor to pump refrigerant gas through the TRU (transport refrigeration unit) when the vehicle engine is off.

Standby units are widely used on more used together with Engine Driven,Diesel Engine Refrigeration Units and electric refrigeration units, so that while the vehicle is parking and engine is off, driver can connect the standby unit with a charging pile to cool.

Corunclima has Split electric standby system and Integrated electric standby system (integrated in the condenser) for your choice.
