ASATI introduced the bias-harness cable net system in 1968, covering a track and field facility at Harvard University. Since then, this patented system has been applied to hundreds of ASATI recreational and commercial air-supported structures.
This unique safety network of vinyl-coated cables can withstand the most severe environmental conditions, while the air-tight anchorage system provides even greater stability. Angle bars anchor the cable net and the structure envelope.
With this system, fabric loads are transferred first to the cable net system, and then to the anchorage system. Even in extreme conditions, like 150 miles per hour winds or 50lbs of roof snow load, fabric loads are reduced to about 6 pounds per square inch. These same conditions in an unharnessed structure could cause loads in excess of 100 pounds per square inch, resulting in the failure of the structure. ASATI's cable net construction provides the most fail-safe air-supported structure in the industry- exceeding building code requirements.
On top of providing an improved safety factor, the full bias system improves the longevity of the fabric skin. This is because the fabric experiences a reduced load which puts less wear on the fabric fibers. If you plan on building a premier facility it only makes sense to use a cable system that best protects your investment.
ASATI's primary Inflation System is pre-engineered for stability and is suitable for unheated structures. It is a complete, self-contained system protected by an exterior weatherproof housing.
The system's electric motors and components are U/L listed, and the blowers are tested in accordance with AMCA standards. The emergency backup auxiliary pressurization system is fully automatic, with controls to start the engine and pressurize the air structure in the event of static pressure loss or electric power failure. The backup system's gas-fueled internal combustion engine drives a fan separate from the primary system. When safe pressure is achieved, the system automatically turns off.
ASATI's packaged HVAC systems provides climatic control along with the pressurization (C.F.M.) to inflate the air structure to its full shape and pressure, automatically maintaining the desired constant interior ceiling-to-floor temperature. The heating system recirculates warm air, eliminating heat stratification. By maintaining a constant ceiling-to-floor temperature the thermostat is satisfied for longer periods of time, resulting in decreased demand for heat.The system is completely pre-wired and pre-packaged to include electric motors, inflation fans, automatic dampers, heaters and air conditioners. The entire system is assembled and contained in an insulated exterior housing, painted with corrosion- and heat-resistant finish, and delivered complete with all required ducting.
ASATI offers automations to control our HVAC units remotely, giving the user the ability to check the status of their structure from the comfort of their home. Also, ASATI units are the most energy efficient units in the industry, utilizing variable frequency drive technology (VFD) to minimize electrical consumption.
ASATI developed the first of its kind LED specifically for the air structure industry. This 1 for 1 replacement of the 1000-watt metal halide provides many advantages to air structure owners. The G2-LED Hanglite provides a 44,200 lumen output for its 15-year lifetime. These fixtures require no bulb changes or ballasts, saving facilities from maintenance costs and wasted space. Also, ASATI’s LED lights are made from high strength aluminum and acrylics so they will never break when hit. Most importantly, these 440 watt LED fixtures provide a 56% reduction in energy consumptions saving the owner hundreds of thousands of dollars over the fixtures lifespan.
ASATI offers three different levels of thermal construction, R-4, R-8 and R-12. Our thermal liners are made with a tabbing system to maintain consistent thermal value across the entire structure and minimize heating/cooling loss. Without this tabbing system, the thermal value can be reduced to as little as half of what ASATI thermal liners achieve. In most cases, ASATI recommends triple wall construction (R-8 thermal value) to maximize energy efficiency. This is because triple wall construction provides the largest insulation value while still allowing the air structure fabric to remain translucent. By being translucent, the facility will require no lighting during daytime operation hours, significantly cutting lighting costs. In extremely hot or cold environment, ASATI has found that placing bubble foil insulation in-between the liners to achieve R-12 thermal value (polyethylene bubble film in-between aluminum polyester sheets) provides the greatest savings as the heating/cooling costs of these structure account for the largest part of operational costs.
ASATI air locks allow people and vehicles to enter and exit safely without changing the internal static pressure of the dome. The all-aluminum revolving door's vanes act as an airlock even when a large number of people are entering and exiting.
An emergency exit, center-pivot, side-swing door opens outward without force and automatically closes against the structure's internal pressure. This door is all-aluminum, welded together to form a solid unit. It is lightweight and easy to remove and the Lexan vision panels on both of the doors are unbreakable and designed for lifelong service.
The rustproof frame, U.L.-approved electric motors, hardware, and fabric cover are pre-packaged and ready for immediate assembly.
