The new compressed natural gas (CNG) powered Supra multi-temperature truck refrigeration unit from Carrier Transicold has received PIEK certification with a noise level below 60 dB. As noise reduction is particularly important for truck deliveries in high density urban areas, the award-winning Supra unit is ideal for urban distribution, offering fresh and frozen multi-temperature applications in up to three compartments.

“At Carrier Transicold, our focus has always been on developing sustainable refrigeration solutions for our customers,” said Bertrand Gueguen, president, Truck / Trailer International. “The new CNG-powered Supra unit provides an efficient solution to our customers facing new challenges in urban refrigeration transport, particularly related to current and upcoming traffic and air quality regulations.”

Quiet refrigeration units are key when it comes to night time deliveries. Supra unit’s low noise level is achieved through the synergy of technical and innovative specification, including indirect air entry and special top cover designed to reduce acoustic vibrations, sound-absorbing materials, and integrated foam sound insulation on unit doors.

The overall benefits of the sustainable CNG solution compared to compression ignition diesel engines include an up to 95% reduction in particle emissions, up to 70% reduction in nitrogen oxide emissions, up to 20% reduction in CO2 emissions, as well as the possibility of using biogas made of organic waste, which further reduces CO2 emissions by 80% to 95%.

The Supra unit was designed to use a single fuel source for both the engine on a CNG-powered truck and the refrigeration unit, requiring just a single refill point, which can save time and money and help increase operator productivity.Fitted with an independent tank for the refrigeration unit, it has full autonomy, maintaining cold chain integrity even when the truck is idling or stopped.

“We have seen a growing demand for quiet refrigeration units, especially for urban retail deliveries,” said Lionel Pourcheresse, senior manager, Sustainability & Product Solutions, Carrier Transicold Europe. “With the new CNG-powered Supra, Carrier Transicold offers an environmentally sustainable solution for urban deliveries in European cities that experience increased traffic jams, resulting in high levels of air and noise pollution in overcrowded residential areas.”
