Carrier Commercial Refrigeration Europe's CO2OLtec® integral refrigeration system and energy efficient remote cabinets have helped tegut… supermarket in Marburg-Cappel, Germany become the first supermarket to receive a Blue Angel ecolabel for environmental responsibility. Carrier, which operates in Germany as Carrier Kältetechnik Deutschland GmbH, is the world's leader in high-technology heating, air-conditioning and refrigeration solutions, and is part of UTC Climate, Controls & Security, a unit of United Technologies Corp.
The environmentally sustainable CO2OLtec® system helps improve the store's energy efficiency and reduce its carbon footprint by using the natural refrigerant carbon dioxide (CO2), which has a Global Warming Potential of one.
Since 1978, the Blue Angel ecolabel has been awarded to more than 12.000 environmentally sustainable products and services from approximately 1.500 companies in Germany. The designation helps consumers make purchasing decisions based on a set of exacting environmental standards. The Blue Angel ecolabel designates that a product or service meets high standards when it comes to its environmental, health and performance characteristics.
In order to receive this highly regarded environmental label, tegut… had to fulfill numerous criteria including refrigerated display cabinets with glass doors, photovoltaics on the roof, use of natural refrigerants and LED lighting, leaflets made of recycled paper and on-site facilities for bicycles. Carrier was tegut…'s first choice for sustainable, energy efficient refrigeration equipment.
"The energy consumption of this flagship store was reduced by 30 percent compared to conventional, older stores," said Detlev Müller, head of facility and energy management, tegut…. "With refrigeration being one of the largest energy consumers in a supermarket, for us it was only natural to partner with Carrier to achieve the best and most sustainable result."
With Carrier's CO2OLtec integral system, tegut… has chosen to install a sustainable technology using CO2 for refrigeration as well as for heating of the store. All of the wasted heat created during the refrigeration process is collected and redistributed for heating via the CO2OLheat® module. This integration of refrigeration and heating enables significant levels of energy efficiency, cutting energy costs by 35 percent while reducing greenhouse gas emissions by more than 50 percent. Refrigerated display cabinets with features such as glass doors, LED lighting and dual speed EC fans provide additional energy savings.
"We are proud to contribute to tegut…'s Blue Angel ecolabel designation with the installation of our innovative integrated CO2 refrigeration system and refrigerated display cabinets," said Udo Laeis, general manager, Carrier Commercial Refrigeration, Germany.
