Cool Employees • Increase Productivity • Reduce Effects of Humidity With high ceilings and abundant square footage, large industrial facilities such as warehouses and manufacturing plants present a ventilation challenge. Cooling and heating these spaces is a challenge because treating that much air without spending a fortune on HVAC equipment and operating costs is nearly impossible. An excellent solution is large industrial ceiling fans – also known as HVLS (High Volume, Low Speed) fans – which deliver a cost-effective climate control solution by generating large amounts of airflow. MacroAir’s big industrial fans create a cooling effect, help control the effects of humidity, and can also help conserve heat in colder months.
