The Active Thermal Transport System uses advanced BioPCM panels inside the trailer, so cold is stored where the cargo is and the compressor runs far less.
Get a free fleet assessmentGreentek reports up to a 70% reduction in fuel consumption*, lowering operating costs and extending equipment life by cutting compressor run time.
Consistent temperatures through the whole trip reduce spoilage, including for pharmaceuticals that are sensitive to humidity and condensation.
Less fuel burned means lower carbon emissions, helping your business meet its sustainability and ESG goals.
With the refrigeration unit or vehicle off, the interior stays cooler and more stable 35% to 60% longer*, a major advantage at loading stops, power interruptions and last-mile deliveries.
Shorter compressor and engine run times reduce wear on refrigeration equipment and lower maintenance costs.
Panels move between trailers without losing effectiveness. When the fleet is refreshed, they are reinstalled in the new vehicles.

01 · Assessment and customizationWe assess your fleet's needs and challenges, then customize the ATTS solution for your refrigerated transport.
02 · InstallationCertified technicians install the system efficiently, with minimal disruption to your operations.
03 · OptimizationOnce installed, the system is fine-tuned for maximum fuel savings and temperature control.
04 · ResultsFuel savings, lower emissions, steadier temperatures and less wear on your refrigeration equipment.
We recommend a measured pilot on a few trailers first: fuel or reefer run time before and after, plus a temperature hold test with the unit off. The pilot results become the case for the rest of the fleet.
Talk to us about a pilot“I was initially skeptical about how the GCCS would reduce fuel costs, but I decided to give it a try. Ken sent someone to install the system in our oldest trailer, and the results were astonishing. The driver thought the system was broken because the truck wasn't running constantly like before. The trailer became more efficient than our newest ones, performing beyond our expectations.”

Typically only a few hours per trailer.
Yes. It is designed to move from one trailer to another without losing effectiveness.
No. It is built to last without performance degradation, and it reduces compressor run time.
