Thermo King, a manufacturer of transport temperature control solutions for a variety of mobile applications and a brand of Ingersoll Rand, announced today that its entire range of the SLXe™ trailer refrigeration units compatible with next generation, low global warming potential (GWP) R-452A refrigerant, are now ATP[1] certified.


Thermo King was the first manufacturer to introduce the new R-452A refrigerant in its refrigerated transport products earlier this year and already sold over 1000 of these trailer units in Europe. In addition to the already available range of SLXe single-temperature trailer units, customers can now benefit from the same environmental benefits with the SLXe Spectrum refrigeration units for multi-temperature trailer transport applications. This includes the extra quiet, Piek[2] certified SLXe Spectrum Whisper Pro version.


“The ATP certification obtained by the entire range of the SLXe trailer solutions with

R-452A refrigerant proves the refrigeration performance of the Thermo King units with the new lower GWP refrigerant,” said Karin de Bondt, vice president and general manager for Truck, Trailer and Bus at Thermo King in Europe, Middle East and Africa. “Our customers can now easily combine the same high efficiency and reduced sound levels of the Thermo King single and multi-temperature trailer applications with an improved environmental performance.”


The entire range of SLXe trailer units is compatible with the next generation Chemours Opteon™ XP44 (R-452A) refrigerant which has about a 50 percent lower GWP value than the current refrigerant. It is part of the EcoWise™ portfolio of products created by Ingersoll Rand for its climate and industrial refrigerant-bearing solutions designed to lower environmental impact with next generation, low GWP refrigerants and high efficiency operation.



The Thermo King SLXe range features the following enhancements contributing to further lower the environmental impact and increase flexibility of operations:



The performance of the Thermo King SLXe range operating with R-452A was tested by several recognized independent testing and qualification institutes specialising in refrigeration located in France and the United Kingdom. The certification is issued along the Agreement on the International Carriage of Perishable Foodstuffs and on the Special Equipment to be Used for such Carriage (ATP) by United Nations Economic Commission for Europe.
