Supra City Truck Refrigeration Line Quiet Enough for Night Deliveries

02 July 2012

Carrier Transicold Europe’s new Supra City refrigeration unit for trucks is a low noise unit, below 60 decibels, making it compliant with Piek standards and meeting the requirements of customers who need to make night-time deliveries to retail and convenience store customers in and around residential neighborhoods. Carrier Transicold helps improve global transport and shipping temperature control with a complete line of equipment for refrigerated trucks, trailers and containers, and is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).

The latest addition to the City Line of environmentally sustainable solutions designed to help transport professionals meet the rigors of doing business in urban areas, the Supra City unit’s lower noise levels have been achieved thanks to a specific design developed to reduce noise emissions, which includes:

- Indirect air inlet and top cover designed to reduce acoustic waves - Acoustic material to absorb acoustic waves and sound emissions - Doors with integrated, sound-absorbent foam

Piek standards were established in the Netherlands in 2003 to respond to growing concerns from local government and supermarkets, and stipulate that noise levels during night deliveries (from 10:30 p.m. to 7:00 a.m.) must not surpass 60 decibels, the equivalent of normal conversation. Under Piek standards, night deliveries are permitted, but only if specific noise level restrictions are met.

“We have seen a rising demand from the retail business sector in particular for low-noise units,” said Lionel Pourcheresse, product manager, Carrier Transicold Europe. “As local authorities throughout Europe seek to address the issues of increasing traffic congestion, air pollution and noise disturbance in crowded residential areas, Carrier Transicold aims to provide an answer to these challenges with the City Line.”

By expanding the periods allowed for store deliveries, supermarket shelves are better stocked and consumers are better served. In addition, night deliveries lead to less time being spent on the road and hence less daytime congestion, fewer road accidents, lower carbon dioxide (CO2) emissions and fuel consumption, helping to improve customers’ bottom-line. Residential neighbors also will appreciate not having their sleep disturbed thanks to quieter deliveries.

The Supra City unit is available in two versions: Supra 950 City, offering 8500 Watts, and Supra 950 MT City, offering 5500 Watts, for multi-temperature applications. The Supra City line builds on the Supra range’s proven reliability and performance, which offers enhanced product protection and lower operating costs as a result of extended unit life and reduced downtime. Carrier Transicold’s City Line also includes:

Vector™ City with E-Drive™ all-electric technology for trailer refrigeration. Generating a noise level below 60 decibels, the units are certified compliant with Piek standards, making them suitable for night deliveries.

Supra City Z, zero engine refrigeration unit for trucks. By removing the diesel engine, the Supra City Z unit relies on the Euro V-compliant truck engine for power and helps to reduce emissions of nitrogen oxide (NOx), carbon monoxide (CO), hydrocarbons and particulate matter.

The Supra City line is backed by Carrier Transicold’s extensive, reliable after-sales service network, which contributes to delivering maximum operation efficiency. Carrier Transicold’s European service network is composed of more than 550 service points with 1,700 fully-trained technicians proficient in the installation, maintenance and repair of all Carrier Transicold refrigeration products. A multi-lingual call center provides customers with 24-hour assistance in 17 languages.
