Honeywell helps reduce Tesco's carbon footprint

31 January 2012

Honeywell has announced that Tesco, one of the world’s largest supermarket chains, is using Honeywell's Genetron PerformaxTM LT refrigerant in 75 of its stores in Poland

“Tesco Poland decided to use Genetron Performax LT refrigerant to help us meet our aggressive carbon footprint reduction targets,” said Robert Hurley, Group Engineering Standards & Energy Manager for Tesco Group Property.

“Compared to R-404A, the refrigerant we previously used, Genetron Performax LT offers 50 percent lower global warming impact. Moreover, the installation and commissioning have been very smooth with no downtime.”

Paul Sanders, Managing Director for Honeywell Fluorine Products in Europe, Middle East, Africa and India, said, “Genetron Performax LT can help supermarkets' bottom line because it is more energy efficient and requires minimal changes to the equipment supermarkets are currently using.”

Sanders also noted that Performax LT is a class A1 refrigerant, meaning that it has low toxicity and is non flammable.

Sixty of the Tesco stores using Genetron Performax LT are newly built. The remaining 15 stores were retrofit applications, where Genetron Performax LT replaced R-404A, an older refrigerant that has higher global warming potential.

Tesco installed Genetron Performax LT mainly in small format stores of up to 1,000 square meters, as well as some supermarkets (2,000 to 3,000 m2) and large hypermarkets of more than 4,000 square meters. The total of 75 stores has been implemented between June and November 2011 whilst Tesco will continue with the roll-out plan in Poland.

According to the industry testing, systems using Genetron Performax LT, also known as R-407F, consume up to 15 percent less energy than systems using R-404A and up to 7 percent less than systems running R-407A at medium temperature. Use of Genetron Performax LT can also reduce carbon dioxide emissions by up to 40 percent.

Genetron Performax LT consists of a highly efficient mixture of conventional hydrofluorocarbon refrigerants (R-32, R-125 and R-134a). It can be used for new commercial installations and also to retrofit existing R-404A, R-407A and R-22 installations with minor adaptations.

Honeywell's Fluorine Products business is a leader in the manufacture and supply of zero-ozone-depleting refrigerants used by top air-conditioning and refrigeration makers worldwide and blowing agents for energy-efficient foam insulation.

Tesco is one of the world’s leading retailers. It has set ambitious targets to reduce its own carbon footprint, reduce the emissions from the supply chain, and help customers to reduce their footprints too. The target is to reduce 50 percent of carbon dioxide emissions by 2020 and to become a zero-carbon business by 2050.
