Demand Regulator Test Facility (DRTF)
The Demand Regulator Test Facility (DRTF) is a fully integrated laboratory system offering the capability to measure the dynamic performance of new and serviced SCUBA demand regulators to 80msw (dry) at the maximum ventilation requirements of EN250:2014.
- View real time displays:
- Mouthpiece pressure
- Chamber depth
- Interstage pressure
- Breathing volume
- HP cylinder pressure
- Pressure-Volume plot
DRTS incorporates the instrumentation and automated test sequence controls, pneumatic systems and chamber depth controller.
The test vessel is fitted with a quick release lid system and automatic Chamber Depth Control (CDC) to ensure accurate and safe testing.
- Combines the effectiveness of a compact horizontal test pressure vessel with a fixed 2.5 litre displacement breathing machine test
- Used by manufacturers for both the initial phase of product development and for routine testing of production demand regulators
- Quickly identify regulators passing / failing specified test criteria and to print Test Certificates
- Selectable breathing rate providing ventilations in the range of 25 to 100 litres per minute
- Chamber depth can be pre-set and adjusted during testing
- User-friendly, accurate test method displays standard Pressure-Volume plot with corresponding performance of the first stage output pressure
- Easy archival, retrieval and printing test results displays from PC archive
The Breathing Simulator is constructed from Hard Anodised Aluminium / Stainless Steel and rated to a maximum working pressure of 8 bar. Mounted on a machined, solid base plate it is designed and built for maximum robustness, reliability, and longevity.
Micro-switches and lights indicate when the chamber is fully closed and engaged so pressurisation can proceed.
