Staff, plants and customers at Dedeman are breathing a sigh of relief following the installation of Breezair evaporative coolers.

Dedeman is the largest chain of DIY (Do-It-Yourself) stores in Romania specialized in home and garden products.

The area dedicated to garden products and plants in the store is designed as a greenhouse, since this is the most suitable structure able to provide an appropriate climate for the plants’ life.

However, this type of construction has the great disadvantage of overheating during summer. Having glass on all sides of the garden areas used to experience temperatures of up to 40°C during summer months causing plants to wilt and die, great discontent on the staff and customers’ loss. Plants constantly needed fresh air to support the process of photosynthesis and respiration, staff and customers needed comfortable temperatures to stay in the area. A cooling solution was definitely essential.

As a first option, Dedeman looked into the possibility of using conventional air conditioning to cool the area. This would unquestionably have granted an effective cooling but operating costs would have been prohibitive considering the size of the area to cool down. Breezair would not only have improved conditions for customers, staff and plants but would also have been cost effective to install and run and would have provided a short-term payback, as the garden area would have lost less stock and increased sales. In addition to this, dust, insects and other air contaminants would have been filtered out from the coolers while the higher humidity would have reduced the plants’ need for irrigated water and prevented wilting.

In this scenario, West Air Group, our distributor for Romania, approached Dedeman and suggested an alternative solution: the Breezair cooling systems. “Dedeman was familiar with the conventional air conditioning system but did not know the evaporative cooling technology” explained Mr Sorin Lumina, owner of West Air Group, “and in the first instance the Breezair solution was regarded with a bit of mistrust”. Being confident with the potentials, Mr Lumina offered Dedeman a trial installation on a single store, to allow the customer to test the system for a year and then decide for the future.

The first Breezair unit was installed at Dedeman Roman in 2012 and the store was monitored throughout the whole 2013. The system performed so efficiently and Dedeman was so satisfied that in 2014 they had the Breezair cooling systems installed in the Dedeman stores (garden areas) all over Romania: from Bucarest to Constanta, from Tulcea to Braila, Galati, Comanesti, Suceaava, Bistrita Nasaud, Baia Mare, Satu Mare, Oradea, Cluj, Alba Iulia, Targu Mures, Miercurea Ciuc, Ramnicu Valcea, Slatina, Drobeta Turnu Severin, Timisoara, Resita, Targoviste, Pitesti. For the moment, 141 Breezair units were installed along different stores in areas between 600 and 2,000 sqm which required between 6 and 8 coolers per store. To date, the Breezair evaporative system remains their first choice every time a new store is opened.

The outstanding efficiency of the cooling system, the limited electricity consumption (about 6 Kwh for a 2,000 sqm greenhouse) and the minimal maintenance costs are the features that made Breezair a perfect choice.

The advantages of the Breezair industrial evaporative air cooling system can be summarized as follows:

  • Operating costs by 80% lower compared to conventional air conditioning;
  • Easy and simple to install (costs by 50% lower compared to conventional installations);
  • Easy to maintain;
  • No synthetic refrigerants used, no additional pipes and no compressor;
  • High efficiency at low energy and water consumption;
  • 100% fresh air (no dust, toxic gases or odors recycled);
  • No dry air, controlled level of humidity;
  • Environmentally friendly thanks to reduced power use and no harmful emissions
  • Spot cooling: another important advantage of this system is that it is able to cool only selected areas of the store and not the entire store. Spot cooling consists of installing units that deliver cold air just to the areas where cooling is required. This is not achievable with the conventional air conditioning systems.
