Seismic Testing in New Zealand Lab Proves the Reliability of HUBER & RANNER Air Handling Units

New Zealand is one of the country’s at most risk of seismic events due to its challenging position on the Pacific “Ring of Fire”.  In the wake of the deadly Christchurch earthquake in 2011, the country has moved rapidly to implement a variety of laws, regulations and standard practices that ensure the built environment is better prepared to withstand future seismic events. One such requirement is that for facilities of critical post-earthquake importance, such as hospitals, there are enhanced requirements on building services equipment, including air handling units, to demonstrate the capability to withstand such earthquake events and continue to function properly.

In order to validate the capability of HUBER & RANNER units, a demo AHU was manufactured in our Taicang factory and shipped to New Zealand to undergo “Shake Table Testing” at Holmes New Zealand’s testing laboratory. Shake table testing, in this case undertaken according to international testing standard AC-156, simulates the effect of an earthquake on equipment, using typically acceleration profiles and forces of real seismic events. The AHU was inspected and test-run before and after, validating that our Y-CASE air handling units are suitable for use in such high-risk facilities.

Our thanks to Holmes in New Zealand for being a highly supportive testing partner. We are now proud to say that we are the first AHU manufacturer offering seismically-proven, AC-156 tested units into the New Zealand market!
