Carrier Transicold France’s new compressed natural gas–powered Supra multi-temperature truck refrigeration unit has just received PIEK certification, with a noise level below 60 decibels.
“Noise reduction is particularly important for truck deliveries in high density urban areas in the morning or late at night, as more municipalities across Europe enact noise ordinances,” Carrier Transicold said in a statement. “This award-winning Supra unit is ideal for urban distribution, offering fresh and frozen multi-temperature applications in up to three compartments”
PIEK standards, introduced in the Netherlands in 2003, were reportedly developed in response to growing concerns from local governments and supermarkets to reduce noise levels for night deliveries (between 10.30pm and 7am). PIEK-registered technology must not surpass 60 decibels, the equivalent of normal conversation. While the Netherlands paved the way in this field, the standards have been adopted in many European cities. The CNG-powered Supra refrigeration unit engine reduces noise and vibrations as well as fumes and smoke, as compared to compression ignition diesel engines, which helps improve operating conditions for drivers and the communities they serve.
“At Carrier Transicold, our focus has always been on developing sustainable refrigeration solutions for our customers,” said Carrier Transicold President – Truck/Trailer International, Bertrand Gueguen. “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.”
According to Carrier Transicold, the new CNG-powered Supra unit’s low noise level is achieved through the synergy of technical and innovative specifications: Indirect air entry and special top cover designed to reduce acoustic vibrations; sound-absorbing materials; and integrated foam sound insulation on unit doors.
“We have seen a growing demand for quiet refrigeration units, especially for urban retail deliveries,” said Carrier Transicold Europe Sustainability & Product Solutions, Lionel Pourcheresse. “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.”
