UK based supermarket retail giant Tesco has lead by example in recent years when it comes to saving energy and reducing CO2 emissions from their retail stores.

In trials of HY-SAVE® Liquid Pressure Amplification (LPA) system at a Tesco store in Ireland, independent energy consultants saw the amount of energy consumed by the refrigeration plant reduce by 24%.

Previously at the store, condensing temperatures had to be kept unnecessarily high at around 32°C to combat system flash gas and to keep the stores evaporators operating efficiently. Since LPA® pumps were installed in the system’s liquid line, condensing temperatures have been reduced to 20°C (68F) whilst delivering vapor-free refrigerant to the stores display cabinets and cold rooms maintaining peak efficiency.
