Rigorous testing

ADA’s patented Duct Suspension System has been through rigorous testing and passed Level 3 in both transverse and longitudinal directions - a very successful result! Level 3 is the highest test for Seismic testing on a world standard. ADA are leading the way in designing innovative approved systems that meet the critical seismic HVAC/R design requirements of a building project. If you’re looking for seismic approved systems you can’t go past ADA’s ever increasing range. Seismic really does matter.
