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
- Indirect air entry and special top cover designed to reduce acoustic vibrations
- Sound-absorbing materials
- Integrated foam sound insulation on unit doors
- Reduction of noise, vibrations, odors and smoke, improving operator and neighboring community comfort
- Possibility of using biogas made of organic waste
In addition to noise reduction, the sustainable CNG solution helps significantly reduce emissions while increasing operational efficiencies. Compared to compression ignition diesel engines, overall benefits include
- Up to 95 per cent reduction in particle emissions
- Up to 70 per cent reduction in nitrogen oxide emissions
- Up to 20 per cent reduction in CO2 emissions
- Possibility of using biogas made of organic waste, further reducing CO2 emissions by 80% to 95
esigned to use a single fuel source for both the engine on a CNG-powered truck and the refrigeration unit, the Supra unit requires 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.
The new CNG-powered Supra unit complements Carrier Transicold’s City range and engineless refrigeration range, all PIEK certified, including
- Vector 1950 MT City and Vector 1550 City, featuring the E-DriveTM all-electric system for trailers
- Supra 1250 City
- All Carrier Transicold engineless refrigeration units for trucks
