ACP&D Limited are to offer High Volume Low Speed (HVLS) fan systems for HVAC applications.
High Volume Low Speed (HVLS) fan systems for HVAC applications were developed by MegaFan in the USA during the 1990's from a concept of using a highly efficient extended airfoil blade that would circulate a large column of air at just the right speed required to optimize the "cooling effect". The specially designed airfoil blade is quiet and extremely efficient it produces minimal air disruption directly below the fan. It is very effective in large commercial and industrial facilities where employee comfort is the primary goal.
The MegaFan can help cool, de-stratify layered air, warm whilst saving energy by better control of a building's temperature profile. The MegaFan system comprises 6 or 10 blades with a fan diameter from 8 to 24 feet, a 0.75kW or 1.5kW motor and gearbox plus the variable speed drive mounted in an enclosure. Our experienced engineers are able to install and commission the system to your requirements.
Applications in industry comprise the following:
• Cool Machinery
• Dry wet floors and control moisture, mould, bacteria and condensation.
• Creates a constant floor to ceiling temperature with low speed high volume air changes.
• Provides comprehensive air coverage and drastically improves areas with hot, cold, stale and stagnant air.
• Promotes cost savings by leveraging HVAC systems, enhancing ventilation systems and reducing the overall energy costs within a large space.
• Dilutes concentrated air.
• Helps keep your most valuable asset working and comfortable – your employees, visitors, and customers.
The applications in agriculture comprise the following:
• To cool and provide healthier environments for dairy cows, horses, and other livestock.
• Used for crop cooling and temperature equalization.
In many cases there are rebates, grants, and incentives available in many areas and from the government for energy efficient equipment installation. It takes 26 high speed fans to move the same amount of air as only one MegaFan 24 foot 1.5kW fan. Consider energy consumption. It costs more to run the high speed fans for one hour than to run the MegaFan for eight hours! The 20 foot six blade MegaFan uses just 0.576 kW at maximum speed and at 7.5 pence per kilowatt that's less than 4.32 pence per hour! Most MegaFan customers do not need to run their fans at maximum speed as they get all the reticulating air they need at about 75% of maximum therefore the energy savings are normally even greater!
The HVLS MegaFan can be found in the following locations:
• Facilities and Large Structures that need air movement
• Manufacturing, Production, & Assembly Facilities
• Warehouses and Distribution Centres
• Large Commercial Complexes
• Automotive and Truck Repair Garages
• Auto Service Centres
• "Big Box" Retail Stores
• Aircraft Hangars
• Produce Packing Sheds
• Livestock Pens
• Free-stall and other Barns
• Shopping Centres
• Auditoriums
• Sports Arenas
• Gymnasiums
• Tents
Because of the large diameter of an HVLS MegaFan and the resultant column of air size these fans produce a unique and effective deep wall of horizontal moving air. This is called a horizontal floor jet. A floor jet is relative to a fans diameter and to a lesser degree the speed the fan is turning. Once the floor jet reaches it potential it migrates outward and radiantly until it meets a side wall or other large barrier; there it continues to entrain and circulate. This is what makes HVLS fans so effective. Small high speed fans regardless of their number cannot produce a similar floor jet of moving air. For example; and 8 FT fan would produce a floor jet of air approximately 1 metre deep. A 24 FT fan would produce a floor jet of air 2.8 metres deep.
MegaFans require very little maintenance. Both the motor and the gearbox (which is lubricated for life) have a 3 year. And all other components have a lifetime warranty.
