Air Handling Unit Receives Top Hurricane Rating from Miami-Dade County
Nortek Air Solutions' welded frame (WF-2) air handling unit (AHU) cabinet complies with Miami-Dade County’s (Fla.) High Velocity Hurricane Zone (MDC HVHZ) building code.
Nortek Air Solutions (NAS), the largest manufacturer of custom HVAC equipment in North America, received a Notice of Acceptance (NOA) Nov. 19 on its Welded Frame (WF-2) air handling unit (AHU) cabinet for compliance with Miami-Dade County’s (Fla.) High Velocity Hurricane Zone (MDC HVHZ) building code.
The WF-2 was tested at 227 pounds per square foot (PSF), which more than doubles the nearest competitor’s AHU cabinet strength of 110-PSF. The PSF rating equates to approximately a 301-mph wind load rating, depending on equipment elevation and building importance (risk factor). The WF-2 NOA (No. 20-0630.02) lays testament that it’s the HVAC industry’s number one AHU cabinet for structural integrity against high wind events. The highest wind event recorded globally was the Oklahoma City, Okla., area’s 1999 Bridge Creek-Moore F5 tornado listed at 301-mph.
