PRS Technology Provides World-Unique Benefits
to Fresh Food and Pharmaceutical Logistics
Official certified tests have demonstrated that PRS Reefer Containers are extremely environmentally friendly.
Comparative Energy Consumption Test : 20’ PRS Reefer Container vs. 20’ conventional reefer container
|Source||National Test Center - Beijing - People’s Republic of China|
|Ambient conditions||+30° C constant (in accordance with ATP)|
|Internal container temperature||+2 / +4° C|
|Overall test duration||25 days|
The power consumption of the PRS Reefer Container amounted to 799 kWh compared to 4’426 kWh consumed by the conventional reefer container.
PRS Reefer Containers consume electrical energy only during the Thermal Charge, a procedure that needs 48 to 72 hours. After the Thermal Charge, PRS Reefer Containers do not need a further power supply for the Thermal Autonomy period.
|Energy consumed by conventional reefer||4.426 kWh|
|Energy consumed by PRS container||799,8 kWh|
|Percentage of energy saving||81.93%|
The European Commission (EC) is striving to make Europe the world’s first climate-neutral continent by 2050. To achieve this goal, the EC presented the European Green Deal, the most ambitious package of environmental measures that enable European citizens and businesses to benefit from a sustainable green transition. The measures are accompanied by an initial roadmap of key policies that range from ambitiously cutting emissions, to investing in cutting-edge research and innovation, and to preserving Europe’s natural environment.
PRS’s Cutting-Edge Technology, which has a direct certified energy saving rate of 81,9%, falls in accordance with the principles of the European Green Deal.
The refrigeration compressor of conventional reefer trucks and trailers consumes 60 liters of fuel per day.
According to Eurostat, there were 4,3 million road freight vehicles registered in the European Union (EU) in 2018. Assuming that 400.000 of those vehicles are reefer trucks and trailers, the overall daily fuel consumption amounts to 24 million liters of fuel for refrigeration only.
Since PRS Reefer Containers have a Thermal Autonomy of 25 days and pondering the current average fuel price of 1,2 €/l., 28,8 Million € can be daily saved, equivalent to 6.336 Million € per year.
Considering that one liter gasoil produces 2,57 Kg of CO2, thanks to PRS Technology, the CO2 production will be reduced of 61.680 tons CO2 per day, equivalent to 13,57 million tons CO2 per year.
This without considering the possibility of rerouting a significant portion of the road traffic to the intermodal one thanks to PRS.
PRS makes the change in modes of transportation possible thanks to the high quality of preservation that is provided by PRS Reefer Containers. Tests have proven that the quality of the products after maritime transport by PRS Reefers Containers was equivalent, and at times, better than products transported by airfreight.
While fresh food shipped in conventional reefers has to be urgently transported by trucks, fresh food shipped in PRS Passive Refrigeration Equipment can be carried on more sustainable carriers, such as trains.

If intermodal transport in the form of road-rail-road is used rather than road only, the yearly saving of fuel becomes extremely more important, as it allows a reduction of fuel consumed for transport of 60 billion liters at a value of 90 billion € and a CO2 emission decrease of 156 million tons per year.
PRS Technology is also confirmed to be sustainable as it eliminates the use of secondary packaging, which reduces environmental pollution.
PRS Reefer Equipment, having no moving parts, is noise-free: terminals, stations, distribution platforms, truck rest areas and city distribution are therefore not affected by the noise level typical of conventional reefers.
Several rural areas, significantly in Africa, Far- and Middle-East of Asia and South America, have underdeveloped infrastructure and unstable, discontinous power supplies. While the use of renewable energy is continuously increasing, the discontinuity is a major drawback for refrigeration equipment. Passive Refrigeration completely overcomes this limit.
