Breezair evaporative cooling systems are extensively installed and working perfectly in locations across Europe for more than 30 years (with regular service and maintenance). In the commercial/industrial sector, hours of operation and environmental conditions often mean more regular servicing is necessary for the most efficient operation of your air conditioning unit(s). Always refer to your Owner’s Manual for scheduled service intervals. You can always contact us if you have more questions or reach out to your local distributor by clicking here.
