Hyperlite Chambers are the most extensively tested hyperbaric chambers in the industry. Our multiplace chamber systems have completed a rigorous Prototype Test program, witnessed by Lloyds Register as in compliance with ASME PVHO Case 18.  In addition, at the request of a Military Customer, The Hyperlite DL5 underwent a damage tolerance test with one (1)  .762FMJ fired from an M16 rifle. The first known test of it’s kind, the results demonstrated that even if the pressure vessel is hit by a large rifle bullet, the pressure vessel will not catastrophically fail. Instead the system depressurised in a slow controlled manner, demonstrating that the materials used in the Hyperlite DL5 are more inherently safe when being operated in austere environments when compared to traditional metallic chambers.
