Effective Summer Cooling

Computational Fluid Dynamics (CFD) analysis shows how cooling is provided in warm buildings when the fan runs in the forward direction. Note the air column produced as well as the air velocities in the enclosed room. As air hits the floor, a wall of air moves away from the center of the fan, cooling the surrounding area.

Winter Heating (Reverse Mode)

Computational Fluid Dynamics (CFD) analysis shows how heating is efficiently provided when the fan runs in the reverse direction. The fan destratifies the space in an enclosed room by mixing air temperatures throughout different air levels. As the fan runs, air is moved toward the walls, forcing warmer air down to ground level. When combined with heated makeup air, or space heating, the space is heated comfortably and efficiently.

Winter Heating Slow Forward Mode

Computational Fluid Dynamics (CFD) analysis shows how heat is dispersed throughout the enclosed space when the fan runs slowly in forward mode. Warm air trapped in the ceiling is mixed with cooler air below to efficiently heat the space.

High Volume Low Speed Fan

The High Volume Low Speed (HVLS) fan is ideal for heating and cooling in a variety of commercial and industrial applications, providing a constant flow of air throughout a space for sensible cooling and de-stratification of warm air pockets near the ceiling. The HVLS fan efficiently and quietly moves a large volume of air at a low operating cost.

Features

  1. Range from 8 to 24 foot diameter
  2. Operates on 1 to 2 horsepower
  3. Effective year round, creating a non-disruptive laminar airflow above floor level to provide effective summer cooling and used at lower speeds for destratification in heating months
  4. User friendly controls with LCD screen displaying real time status of fan speed, space temperature, and status
  5. Customizable microprocessor based controls: Operate manually, automatically, or via building management system; emergency shutdown feature to interlock with the building fire alarm panel
  6. Variable Frequency Drive (VFD) provides soft start and full variable speed operation
  7. Quiet and efficient operation
  8. Low operating expenses for fan and minimal maintenance required – costs approximately 6 cents per hour for one fan at 0.75kW
  9. Safety clips and blade safety links prevent rotor or blade from falling in unlikely failure of the hub or drive system

Certifications

HVLS Models are ETL Listed under file number 104224395ATL-001A and conform to ANSI/UL Standard 507 and CAN/CSA C22.2 No. 113.
