Rapid Decompression Test Chambers

Meets testing requirements for RTCA DO-160

Our rapid decompression test chamber is designed to simulate rapid decompression for testing aircraft avionics. The environmental chamber meets the environmental conditions and test procedures for airborne equipment referenced in the RTCA DO-160 test specification. The DO-160 specification was designed to test sudden pressure changes starting from 8,000 feet to 60,000 feet (536 to 55 Torr)  in 15 seconds. An altitude of 8,000 feet (536 Torr) was used for the initial cabin altitude and 60,000 feet was used for the final cabin altitude after decompression. This test specification is used to identify failures of materials inside of the cabin and the reaction to the surrounding environment.

Rapid decompression test chambers are custom-designed altitude chambers that utilize a large vacuum pump along with various control valves operated by the CSZ EZT programmable controller. Control mechanisms insure minimal overshoot during rapid evacuation and tight control after stabilization at any altitude set point within the full-specified range.

Touch Screen Controller
  • CSZ EZT-570S Touch Screen Controller is designed to save chamber programming and setup time. Standard features data logging, data file access via memory stick or PC, Ethernet control and monitoring, alarm notification via email or phone text message, full system security, online help & voice assistance in multiple languages and more.
  • A Temperature Limit and alarm is included to protect your product.

EZ-View Software
  • RS-232/485 serial communications, Ethernet control and monitoring offer a selection of communications options.
  • EZ-View optional software allows user to control and monitor up to 20 chambers from any location.

Rapid Decompression Cabinet
  • 10" (25 cm) Diameter Flanged Access Port with Schedule 80 Blank Cover
  • Fog-free viewing window and interior light makes viewing workspace hassle free.
  • Fully welded ports and shelf pilasters eliminate potential leaks, increasing the life of your chamber.
  • All liners are constructed from Type 304 brushed stainless steel that is easy to clean. All seams are continuously welded to form a hermetically sealed unit to prevent moisture migration.
  • The chamber exterior is constructed of formed sheet steel for structural strength and finished with a textured polyurethane paint. Customer specified paint combinations are available upon request.
  • Robust Vacuum System - Heavy duty, high capacity vacuum pumps provide reliable performance. System is equipped for controlling altitude setpoints automatically with a regulating rate of ascent and descent by using manual adjustable valves. Flexible section in vacuum lines also prevents transmission of adverse vibration.

Altitude Chamber Refrigeration
  • Pressure gauges allow operating pressures to be continuously monitored and provide early warning indicators.
  • CSZ test chambers utilize refrigerants which are environmentally safe, non-flammable, non-explosive and have a Zero Ozone Depletion Potential (ODP).
