, the online high-end fashion chain opened their third warehouse in Charlton next to the Designing Evaporative Cooling systems for listed buidingsMillennium Dome and chose EcoCooling to provide a cost effective and carbon friendly warehouse cooling system. 14 roof mounted EcoCoolers have been installed along with 8 extraction units to provide cool air both above and below the mezzanine floor.

The coolers are controlled automatically with individual thermostatically controlled wall mounted panels; these are interlinked into the fire alarm system and existing Building Management System to provide a simple safe and secure system.

The temperature in the warehouse is now always below 23°C even on the hottest days, providing comfortable working conditions all year round.

Compared to a traditional refrigeration system the estimated energy savings are expected to be around 90%. A single EcoCooler, rated at 35Kw, can show carbon savings of up to 10,000kg per year and cost less than 15p per hour to run.
