Building on the success of the CryoTech truck product line, Thermo King has developed the all-new CT-15 Spectrum trailer unit.  This radical new design now brings all the advantages of Thermo King’s patented CryoTech cryogenic cooling solution to operators of multi temperature trailers.  With its market-leading low noise, reduced maintenance and outstanding refrigeration performance, this is the solution for operators looking for the best in next generation technology, designed to both minimize environmental impact and outperform conventional systems. 

According to the company’s press release, the secret behind Thermo King’s CryoTech units is the use of recycled liquid Carbon Dioxide (CO₂) as a coolant in an open loop system, allowing zero-emissions refrigeration. While this is not the only cryogenic solution currently available, it is highly innovative in that it provides airflow in the load space, which is essential for fresh produce, and exhausts the cryogen outside the load space. Thus, no CO₂ enters the cargo area, unlike other systems that inject liquid coolant into this space displacing Oxygen.

Furthermore, without the need for an engine or HFC refrigerants, CryoTech systems eliminate the harmful wastes that must be handled and disposed of during the life of a conventional diesel unit. This combined with the excellent recyclability of the equipment further reduces its environmental impact. 

Thermo King has done extensive development to ensure that the CT-15 Spectrum not only meets but substantially exceeds the demanding PIEK low-noise standard.  It requires a maximum operating noise level of 60dBA to permit night-time deliveries. The test measures sound levels at six positions around the vehicle and to achieve the certification none of the measurements may exceed 60dBA.
