Big Foot Systems: The Next Generation of Rooftop Equipment Mounts Debuts in U.S.

Prefab modules support any size, weight or configuration of HVAC equip. & save project labor vs. conventional timbers or welded metal.

Airtec, Fall River, Mass., a leading manufacturer and importer of HVAC/R products, introduces Big Foot Systems, a labor-saving, aesthetic solution for supporting all types of HVAC/R equipment, ductwork, piping and other building services on flat roof applications without penetrating the roof membrane.

Big Foot Systems is the new generation of alternative equipment mounting that replaces old-school methods of corrosion-prone landscape timbers or labor-intensive, welded metal fabrications on-site. Big Foot Systems consists of prefabricated 1.6-square-inch (40-mm) corrosion-resistant, hot-dipped galvanized tube modules supported by 1-square-foot (305-mm) UV-protected, glass-filled nylon footings with anti-vibration mat bases.
Big Foot Systems is available in three standard module packages of 4.3 x 3.3-feet (1.3 x 1-meter); 4.3 x 6.6-feet (1.3 x 2-meter); or 4.3 x 9.8-feet (1.3 x 3-meter) or custom-fabricated with free 48-hour design services to fit any equipment size, weight or configuration.

Other features include:

o Each footing has a vertical height adjustment range of four-inches (100mm) for easy leveling.

o Larger modules of 2-square-inch (50-mm) or 2 x 4- square-inch (50-mm x 100-mm) galvanized tubes are available for larger equipment of up to 10 tons.

o Reroofing requires only removing one leg at a time to replace and lay new roofing membrane, which eliminates disruption to building HVAC services. The system's flexibility also allows easy change-outs or add-ons to existing equipment.

o Clamps are available to lock down all types of HVAC equipment footings to the Big Foot Systems cross-bars.

o Spans between footings can be easily widened or narrowed to accommodate weight-loading.

o Accessories include dedicated and aesthetically coordinated H-frame systems for cable, busbars, piping and ductwork and other building services.

Fix-it Foot is the product line's newest offering consisting of three sizes of rectangular recycled-rubber footings with a 1.6 (W) x 0.8-inch (D) (40-mm x 20-mm) aluminum channel for affixing smaller equipment such as mini-split condensers and piping.

Big Foot Systems is now available to the U.S. market and has been a popular choice among contractors and consulting engineers in Europe for several years with major applications such as BA terminal Heathrow Airport, London.
