CA-HVLS Fans and Controls
High Volume Low Speed Fans
Efficient HVLS Ventilation
- Available in 3-Blade and 6-Blade configurations
- Range from 8 to 24 foot diameter
- Operates on 1 to 2 horsepower, capable of moving nearly 275,000 CFM
- Used year-round with benefits in both heating and cooling conditions
- Quiet and efficient operation with minimal maintenance required
- Low operating expenses, costs approximately 6 cents/hour for one fan at 0.75 kW
- User friendly controls with wall-mounted LCD screen
Year-Round Performance
- Creates a non-disruptive laminar airflow above floor level to provide effective summer cooling
- Provides destratification at lower speeds, or reverse rotation during heating months
- Reduces the recovery time when overhead doors are open via a constant flow of air throughout the space
- Eliminates the need for noisy “man-cooler” type fans throughout the facility
- Will not interfere or disrupt make-up air, heating or air conditioning systems
Superior Construction and Safety
- Motor mount assembly constructed of 1/8" thick epoxy-coated steel and grade 8 hardware
- All mounts constructed of 1/4" thick epoxy-coated steel and grade 8 hardware
- Safety clips prevent rotor or blade from falling in an unlikely failure of the hub or drive system
User Friendly Controls
- Variable frequency drive provides soft start and full variable speed operation
- Operated manually, automatically or via building management systems
- Emergency shutdown feature interlocks with the building fire alarm panel
- Real-time status of fan speed, space temperature and status via digital interface with wall-mounted LCD screen
- Microprocessor-based controls provide customizable options
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.
