Nordiska Kompaniet improves shopping and dining experience by treating air with ozone

Mellifiq upgrades one of the oldest department stores in Sweden

Nordiska Kompaniet (NK) is a famous century-old department store in central Stockholm. It opened its doors in 1902, and in 1915 it was moved to the current location. It is today considered one of the most iconic places in the Swedish capital.

The classic department store chose to install two Ozonetech RENA Kitchen Solutions systems in 2019, in order to eliminate the unpleasant odors in the dining area and to recover energy during the cold season.

The customers can now enjoy a better shopping and dining experience, undisturbed by cooking odors. At the same time, the property owners can benefit from lower costs during winter, as the heat energy is efficiently recycled.
