Powerful transport refrigeration that’s sustainable for Earth

We’re on a mission to protect the World’s most precious resources – food, medicine and people – with sustainable cooling. Powered by air, without fossil fuels or air pollution.

It’s not just about reducing climate change. It’s about more food and medicine in the cold chain being better controlled.

And, delivering a better quality of life, from cleaner towns and cities, to less food waste.

With the huge growth in demand for fresh and more nutritious produce, the World needs much more transport refrigeration, but the World can’t let it be run on polluting fossil fuels.

Our Transport Refrigeration Units (TRUs) are powered by sustainable nitrogen, from air – without combustion, fuel or the extraordinary pollution generated by conventional diesel-powered refrigeration. Every Clean Cold Power TRU that replaces a diesel one has the same benefit to clean air as taking 80 cars off the road.

You can imagine what that also means for our climate.

What’s more, Clean Cold Power TRUs are much quieter, reach cold temperatures much faster, and have more precise cooling control than conventional systems.

Cool, clear advantages
  • icon Regulation ready - built to access Low Emission Zones (Clean Air Zones), producing no Particulate Matter, NOx or any other harmful emissions
  • icon Climate conscious - mobile refrigeration emitting no CO2 at the point of use, 80% less overall, or even lower if powered by nitrogen liquefied using renewable energy
  • icon Improved quality - powerful cooling with more precise temperature control
  • icon Productive operation - with faster cool-down to set temperatures and quick refuelling
  • icon Flexible utilisation - 90% less noise than conventional diesel TRUs, when on full power for frozen and chilled loads, means greater access to restricted areas, longer working hours, and less peak-time traffic congestion
  • icon Return on investment - total cost of ownership comparable to conventional systems - less if you factor in forthcoming pollution charges

A supercool innovation

This is how you give your business the edge – and the planet a boost.

Our TRUs are driven by the Dearman Engine™, which efficiently expands nitrogen or air to generate power. Our clever TRU design uses a dual cooling system: first it cools by using the inherent coldness of cryogenic liquid nitrogen (LiN), then a conventional refrigeration cycle is powered by the Dearman Engine™. Two lots of cold from one lot of LiN.

No need for dirty diesel and also much cleaner than alternative ‘green’ TRUs, which rely on a truck’s engine that runs on fossil fuels. They’re better than heavy batteries too – as they’re made from expensive rare elements, require large investment in recharging infrastructure, lengthy charging, and tricky disposal.
