Carrier Announces the 100th CO2OLtec® Integral System Installation in a SPAR Store in Switzerland

Spar store, Schüpfen, Switzerland

SCHÜPFEN, Switzerland, Oct. 2, 2013 – Carrier Kältetechnik Schweiz has achieved a significant milestone with the installation of its 100th CO2OLtec® Integral system in the Swiss SPAR supermarket in Schüpfen, which opened its doors in June 2013. Carrier’s CO2OLtec Integral system, which uses the natural refrigerant CO2, provides a fully integrated approach for the store’s refrigeration, space heating and cooling, ventilation and lighting needs. With this solution, the supermarket expects to achieve measurable gains in increasing energy efficiency, cutting its carbon footprint in half, and streamlining its operations with a single point of contact for purchasing, installation and service. Carrier, the world’s leader in high technology heating, air-conditioning and refrigeration solutions, is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).

The CO2OLtec Integral system leverages the waste heat created during the refrigeration process to cover the full heating requirements of the entire store, all year round, thus eliminating the need for a conventional gas heating system. During warm months, it provides cooling to ensure a pleasant shopping and working environment, and for even greater comfort, the cold air in front of refrigerated cabinets is drawn out and redistributed via the ventilation system.

The performance of this fully integrated concept is orchestrated by Carrier’s intelligent building management system, which controls the interactions among the various components of the commercial refrigeration, heating, cooling, ventilation and lighting systems, to achieve optimal levels of energy efficiency.

Mr. Elias Steiner, Head of Construction Department and Facility Management, SPAR Gruppe Schweiz, said, “The fully integrated planning and execution of the entire building services together with commercial refrigeration make clear sense, because commercial refrigeration in a supermarket is proportionally the largest refrigeration system, the largest waste heat generator and the largest energy consumer. The concept of bringing these all ‘under one roof’ and optimally harmonising the controls is a future-proof idea.”

Philippe Widemann, Managing Director, Carrier Kältetechnik Schweiz, stated, “With increasing market acceptance of our fully integrated solution for supermarkets, Carrier is pleased to count SPAR’s Schüpfen store as our 100th CO2OLtec Integral customer. Our customer can now take advantage of demonstrated energy cost savings of up to 30 percent over the system’s lifecycle, along with the future-proof security that comes with using CO2 as a refrigerant.”

Carrier has the right refrigerant solution for every application, but not every refrigerant is suitable for every application. For further information about CO2OLtec, visit www.carrier-refrigeration.com.
