Westfield Chodov – Prague

In the Westfield Chodov shopping center in Prague, we have set up a preventive plan for inspections and cleaning of ventilation systems, especially for the grease exhausts from the restaurants. Due to the number of business units, this requires large-scale organizing and planning so as not to limit the operation of the shopping center. We also conduct microbiological swap inspections.

Commercial Buildings


Belix deals with remediation and fire restoration projects. In those situations it is necessary to clean the ventilation from soot and smoke - it is also necessary to do this very quickly in order to restore operations as soon as possible. Our organization is based on quick response. The first contact happens within 24 hours and initiating the cleaning within 48 hours.  From a logistics point of view this is challenging but it is deeply appreciated by our costumes.
