The Biggest Hurdles You'll Need to Overcome When Cooling Your Warehouse

To address warehouse climates HVAC components need to overcome a laundry list of challenges. From air leaks, vaulted ceilings, inadequate insulation and over-sized doorways to circulation requirements, building codes and safety regulations, a significantly large fan is simply not enough. Or is it?

Warehouse Challenges

Warehouses are very basic structures. On a macro-scale, each has four walls a roof and a series of loading docks. The complex nature of heating, ventilation and air conditioning requirements stems from warehouse activities and storage requirements.

To ensure adequate environmental temperatures for product storage and workers, airflow needs to penetrate obstacles. Ceiling fans need to accomplish this task while circulating large volumes of air throughout the entire spatial field.

In support of ceiling fans, ancillary components may be required to ventilate work areas and reduce exposure to vehicle emissions in certain applications. While a complete HVAC system requires careful consideration from duct sizing, inlet and outlet location and device selection the benefits of an over-sized ceiling fan cannot be mistaken.

Big Ass Fans

The Big Ass Fan Company manufactures high-volume, low-speed axial fans with impeller diameters up to 24 feet. They can be installed by professional installation staff as a stand-alone system, can be integrated with other HVAC components or integrated into a complete building automation system.

Installation of a Big Ass fan can reduce winter heating bills by up to 30 percent. These fans reduce heat losses by circulating hot air that is otherwise trapped near the ceiling. In warmer climates or seasons they are just as effective. The induced airflow improves cooling rates with workers enjoying apparent temperature drops by as much as 10 degrees Fahrenheit.

These high-efficiency, high-volume, low-speed fans benefit from a proven design. Their largest, most durable industrial ceiling fan, the Powerfoil®X3.0, features patented aerospace-designed airfoils and winglets, a NitroSeal Drive gearbox that is maintenance free and a C-face motor adapter. It is backed by a 15-year warranty. Part of the proven success is due to their partnership with Stober Drives who manufactures the integral nitrogen-filled drive system.

NitroSeal Drive gearbox

The NitroSeal Drive gearbox from Stober Drives was engineered to minimize wear, with exceptionally low backlash and low noise. The two-stage gear reduction gearbox is lubed for life with synthetic oil. It incorporates Stober’s HeliCamber gear technology and SKF tapered roller bearings which provides for less than 11 arc minutes of backlash.

The gearbox is also hermetically sealed and filled with nitrogen to prevent any contaminants from ever interfering with operations. The C-face motor adapter is also strategically placed, allowing for in-situ replacement should the servo motor ever fail or need maintenance.

Conclusion

There are few things that are certain in a warehouse HVAC system. The battle to implement a highly efficient system that effectively moves air throughout the entire spatial field from the ceiling to the floor, even with obstructions such as storage racks and machinery, can be won by installing a Big Ass ceiling fan.
