Self-cleaning cassettes improve efficiency and reduce electronic retailer’s running costs


Daikin Roundflow cassettes’ automatic daily cleaning function, which maintains air flow, improves efficiency and lowers running costs, was a key factor in their selection for a new store in Čáslav.

The self-cleaning units are easy to maintain. They only need emptying twice a year and the lack of dust means they also stay cleaner, for longer.

Expert is an electronics retailer with outlets across the Czech Republic. When it planned to open a store in a new retail park near Čáslav, it needed a climate control solution that ensured comfort all year round, efficiently and cost-effectively.

It chose a system comprising two VRV IV outdoor units linked with indoor units in three main areas: a Biddle Air Curtain and two self-cleaning Roundflow ceiling cassettes in the entrance, as well as four Roundflow cassettes above the shop floor and one in the storeroom.

It was the cassettes’ self-cleaning function that convinced Expert to choose the Daikin system. Daily auto-cleaning prevents dust accumulating on the filters, increasing efficiency, reducing running costs and improving comfort through consistent air flow distribution. Dust can be removed every six months using a vacuum cleaner.

Efficiency and cost savings in the store are improved by two Daikin VAM heat recovery ventilation units. These balance indoor and outdoor temperature and humidity, plus recover heat to reduce system load and increase efficiency.

Along with individual zone controls, the system is controlled by a Daikin intelligent Touch Manager, linked with the Building Management System.
