Carrier adds low noise rating to City units

Warrington, UK: Carrier Transicold has launched the Supra City unit – a Piek-compliant version of its Supra model for rigid trucks.

The low noise system operates at 60 decibels and meets the requirements of customers who need to make night-time deliveries in and around residential neighbourhoods.

The new Supra City unit is available in two models – the Supra 950 City at 8,500-watts for mono-temperature applications, and the Supra 950 MT City, at 5,500 Watts for multi-temperature applications.

The lower noise levels of the Supra City unit is achieved using an indirect air inlet and cover that reduces acoustic waves. It is also manufactured with acoustic material to absorb sound waves and noise emissions.

“As local authorities throughout Europe seek to address the issues of increasing traffic congestion, air pollution and noise disturbance in busy residential areas, Carrier Transicold provides an answer to these challenges with ground-breaking new products like the Supra City unit,” said Justin Grace, managing director of Carrier Transicold UK.

“Being PIEK-compliant means the new Supra City unit reduces the noise generated in low-speed mode to the same level as normal conversation, allowing fleets to make deliveries in urban areas whilst local residents sleep soundly.

“This brings multiple benefits for both the fleet operator and the local community. Night-time deliveries mean trucks spend less time out on the road, leading to reduced daytime congestion, fewer road accidents, lower vehicle emissions and improved fuel consumption,” added Grace.

The Supra City the City line range including the Vector 1850 MT City and Vector 1550 City trailer units. Both systems meet Piek standards and have been recognised with John Connell Awards by the Noise Abatement Society, in 2007 and 2011 respectively.

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 10:30pm to 7:00am) must not surpass 60-decibels. While the Netherlands paved the way in this field, numerous projects aimed at reducing noise pollution have since come to fruition in other European countries including France, the UK, Spain and Germany.

The City line also includes the engineless Supra City Z range, launched last autumn and available in three different versions: the Supra 900 City Z, Supra 1000 City Z and Supra 1000 MT City Z. These units derive power from a hydraulic pump connected directly to the truck engine’s power take off that drives a hydraulic engine inside the refrigeration unit. This helps to reduce emissions of nitrogen oxide (NOx), carbon monoxide (CO), hydrocarbons and particulate matter, whilst sound insulation lowers noise levels to between 61 and 63 decibels in stand-by mode, depending on the specific model.

Supra City Z models suit operators that distribute temperature-sensitive goods in urban or low emission zones eager to reduce their environmental impact without compromising on cold chain protection.
