Carrier Transicold’s new compressed natural gas (CNG)-powered Supra multi-temperature truck refrigeration unit has just received PIEK certification, with a noise level below 60 dB(A). 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. This award-winning Supra unit is ideal for urban distribution, offering fresh and frozen multi-temperature applications in up to three compartments.Carrier Transicold, which operates in France as Carrier Transicold France, is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).
PIEK standards, introduced in the Netherlands in 2003, were developed in response to growing concerns from local governments and supermarkets to reduce noise levels for night deliveries (between 10:30 p.m. and 7:00 a.m.). 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.
The new CNG-powered Supra unit’s low noise level is achieved through the synergy of technical and innovative specifications
