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
