Wind-master® Service and Insulated Roll-Up Doors

Most standard wind-rated roll-up doors operate poorly when exposed to high winds because the curtain deflects and pushes against the guides. That’s why our Wind-Master doors are insulated roll-up doors designed with roller end locks + wind locks to allow the door to move effortlessly through the guides when exposed to a wind load of 20 PSF. Both models offer flexible design, top-of-the-line security, reliability, and durability in service and insulated models. Our insulated commercial garage doors provide excellent climate control and reduced sound transmission.

If your building is in a high-wind area, you need Cookson doors, wind-rated roll-up doors, that you can count on to withstand the harsh weather.

  • Roller end locks + wind locks for wind exposure.
  • Must be motor operated.
  • Minimum door sizes are 6’4” x 6’4”

Maximum sizes for service models:

  • 20'5" wide x 20'4" high (Steel)
  • 20'5" wide x 20'4" high (Stainless Steel)

What is an HVLS Fan?

HVLS fans are large industrial fans that are meant to circulate a large amount of air by using air streams. Air is pulled from above the fan and pushed down in a conical shape to the floor below.

These highly efficient, cost-saving commercial ceiling fans are being used in warehouses, distribution centers, gymnasiums, and a variety of other applications. Rotating at an optimized low speed, HVLS fans move the most air over the largest area at the lowest cost.

At Door Systems, we offer a range of fans for a variety of use cases and are sure to have something that fits the bill for you and your facility. 

  • Kelley Fans
  • Accompanying Control Software
  • Other fan models

How Do HVLS Fans Work?

HVLS fans work in much the same way traditional household ceiling fans do, by creating a downward current that capitalizes on the cooling effects of evaporation. The big difference with these fans, however, is the size. The blades of your typical HVLS fan range from 6 to 24 feet in length— this allows them to move slower while still displacing a larger volume of air compared to your traditional fan. This sizable downward current hits the ground and moves out horizontally, creating a strong but gentle current of air that compounds this cooling effect while using significantly less energy.

The Advantages of HVLS Fans for Industrial and Commercial Use

There are plenty of advantages that come alongside having HVLS fans, commonly referred to as warehouse fans, in your facilities. These fans do more than simply move air— they circulate it efficiently, balancing your indoor environment. This means you’ll see a reduction of stagnant air (less hot or cold spots) coupled with drier floors and no condensation. If your business stores food and produce, your product will stay dry and spoil slower. By stabilizing and balancing the environment your product is kept in, the quality of your stock will be more consistent and maintain that quality across your facility.

HVLS fans have benefits year-round by creating a more comfortable environment while saving on energy costs. They keep people cool in the summer by circulating the air in a space. In the winter, they maintain their usefulness and can be used for destratification— a process that mixes warm air from the ceiling with cooler air at the floor, resulting in a space with a consistent, even temperature. 

These advantages come with reduced energy consumption, making these particularly valuable pieces of machinery for any facility. With large HVLS fans working in tandem with an HVAC system to better regulate temperature from floor to ceiling, a facility can raise the thermostat setting 3-5 degrees. That creates the potential for up to 4% energy savings per degree change— a marked difference in the long term. If your business is looking to foster and support future savings and growth, an HVLS fan in your larger facilities is the way to go.

HVLS Fans are an effective way to reduce the energy costs associated with the upkeep of your facilities, and have shown great results in:

  • Warehouses
  • Industrial Facilities
  • Gymnasiums 
  • Large personnel-oriented events
  • Manufacturing floors
  • Sports centers
  • Medical offices
  • Agricultural Facilities

Optimized Speed

The speed at which warehouse fans rotate is intentional and highly dependent on the specific environmental conditions of the space you choose to install them within. The correct speed will balance the fans' positive effect with their energy use, resulting in the best possible outcome. This means that you’ll see the best performance statistics at the lowest cost to you and your business. How do you determine the settings that get you there? Door Systems has the answer to this question— specialized software that is built to work for you.

iFAN® Software

Accompanying Door Systems HVLS Kelley fans is the iFAN® software. This ingenious system allows you to closely monitor this delicate balance between performance and efficiency— keeping you within that golden window of excellent results at low energy cost. The easy to understand graphic interface of the software allows you to clearly pinpoint where fans are located within your facility, and from there you can easily make real-time adjustments and measure key performance statistics. This aids troubleshooting efforts and allows you to further improve performance. 

iFAN® software allows you to link up to 30 large fans at a time, setting different zones so that each fan can adapt to its unique operational and environmental conditions. Fans can be monitored by time, temperature, to temperature variance settings, giving you full control of the data gathered and empowering you with easy to adjust settings. Ensure that the operational and energy savings goals for your Door Systems HVLS fans are successfully met by networking them with iFAN® software.
