[!--miaoshu1--]:
A truck refrigeration unit, also known as a transport refrigeration unit (TRU) or refrigeration unit, is a cooling or refrigeration unit mounted on a truck or trailer, usually powered by a separate diesel engine or electric motor that drives a compressor to circulate the refrigerant and generate cooling.
The main function of the truck refrigeration unit is to provide a low-temperature refrigeration environment for perishable goods or items that need to be stored in a low-temperature environment during transportation. It is commonly used in the transport of food, pharmaceuticals and other temperature-sensitive products to maintain their freshness and quality.
Guchen Thermo’s Recommendation Based on Models
◆ Short distance transportation: for small to medium refrigerated trucks, Guchen Thermo suggests TR series truck freezer, and C series chiller units. Our TR series and C series units are vehicle engine driven refrigeration systems.
--TR Models are truck freezer units (TR-200, TR-300, TR-450, TR-550 etc.). For truck freezer unit, its refrigerant is R404a, temperature can be range from -30℃ to +30℃ for delivering frozen or deep frozen cargoes, such as ice cream or frozen meat; A freezer unit can also be operated as a chiller if needed.
--C Models are chiller systems for fresh cargo delivery (C-200, C-300). For truck chiller units, its refrigerant is R134a, temperature range is from -5℃ to 25℃ for delivering fresh chilled cargoes, such as dairy product, fruits or vegetables.
◆ Long distance transportation: for big refrigerated trucks/trailers, we strongly recommend TS series engine driven refrigeration systems for a better, safe and effective cargo transportation.
Guchen Thermo cost effective TS series refrigeration units are diesel engine driven truck system whose cooling system rely on not vehicle engine but auxiliary diesel engine, more powerful and efficient. The self-powered diesel truck freezer units, also called as “independent truck refrigeration units”, are the best solution for transport companies operating larger rigid trucks.
Guchen Thermo designed the powerful TS Model to apply on 25~65 m³ truck box, and to deliver exceptional performance.
What are the Different Types of Truck Refrigeration Units?
Direct Drive Units: These units are powered by the truck's engine itself. They provide refrigeration using a belt-driven compressor attached to the truck's engine. Direct drives are simple and cost-effective, but they require the truck's engine to run for the refrigeration system to work.
Independent unit: Independent refrigeration unit with its own independent power supply or diesel drive unit. Self-contained refrigeration units offer greater flexibility as they can run even with the truck's engine off, allowing it to be parked for long periods of time or run overnight.
Hybrid Units: Hybrid refrigeration units combine electric and diesel power sources. They can switch between electric and diesel power when connected to an external power source, such as at a loading dock. This improves energy efficiency and reduces emissions, especially in urban areas where restrictions may be imposed on diesel engine operation.
Each type of truck refrigeration unit has its own advantages and is suitable for specific transportation scenarios. The choice of refrigeration unit depends on factors such as cargo type, distance traveled, dwell time, energy efficiency requirements, and local regulations.
