Forced Air Destratification Fans

Huracan Series Forced Air Destratification Fans

Reznor® Huracan™ destratification fans are available in 4 sizes to support commercial and industrial spaces up to 60 feet in height. Huracan fans move warm air from the upper reaches of the space back to the floor using minimal energy improving overall building energy efficiency and occupant comfort. During heating season, this action  minimizes the amount and cost of heat needed to satisfy occupant comfort or product safety by eliminating the natural stratification that occurs and directing heat already provided to the space back to lower levels. Dripping water and puddles on the floor caused by sweating at the roof can also be eliminated when that warm, humid air is mixed with the cooler, dry air near the floor. Huracan fans can reduce cooling load as well by providing a consistent yet gentle air flow during the heat of summer or warmer days during spring and fall. Integrated louvers and directional brackets enable directed airflow in unusual geometry spaces or around features that block airflow such as warehouse shelving.
Reznor Huracan destratification fans offer a sleek design sure to compliment any space. Huracan fans features a two-tone black and white coated, scratch- resistant paint scheme. Each unit has clean, rounded corners and edges with no visible screws or fasteners which enhances installer safety while providing superior appearance. The Huracan series physically match appearance and complement the full portfolio of Reznor heating products. They can be controlled independently or together with the gas, hydronic or electric unit heaters for optimized space temperature control. Every Huracan fan provides the same superior performance and reliability that Reznor customers have relied on for more than 100 years.

FAN SELECTION HEATING and COOLING NEEDS

1. Choose the appropriate model based on the maximum ceiling height of the space to be destratified.
   a. See the Technical Specification Table for recommended maximum and minimum ceiling height. Each model has a recommended ceiling height range (minimum and maximum provided).
   Example: 30 ft maximum ceiling height in the space. This falls within the range of 18-35 ft which corresponds to the H35 model.

2. Determine the floor area in square feet.
   a. Typically, the area is calculated by multiplying the length by the width.
   b. Unique space layout may require breaking the space into logical smaller geometric shapes and calculating area for each.
   Example: Space length is 70 feet and width 50 feet. 70 feet * 50 feet = 3,500 square feet.

3. Calculate the number of fans needed to properly destratify the space during heating season (1 complete air-turn per hour minimum)
   a. Calculate the number of fans by dividing the floor area by the recommended nominal flow area for the model determined in step 1.
   i. See the Technical Specification Table for the model-specific recommended nominal flow area.
   Example: Per the Technical Specification Table the nominal flow area for the H35 model is 1,500 square feet. 3,500 square feet/1,500 square feet per Huracan fan = 2.33 fans. This indicates 3 fans is needed to ensure proper destratification.
   b. Calculate the number of fans based on space volume.
   i. Calculate the space volume by multiplying the maximum ceiling height by the floor area.
   Example: 30 feet ceiling x 3,500 square feet floor space = 105,000 cubic feet.
   ii. Calculate the number of fans required by dividing the space volume (cubic feet) by the recommended air volume/fan
   Example: 105,000 cubic feet/ 52,500 cubic feet/fan = 2.0 fans
   c. Select the lowest number of fans calculated above unless additional air movement is desired.

4. If cooling air movement is the primary need, then best results are obtained if the number of fans is increased up to double of the calculations for heating. In the example, this means raising the fan number to 3 or 4 fans depending on total airflow desired.
