Pressure Aging Vessel
Model 9300

  
The Pressure Aging Vessel (PAV) uses pressurized heated air to simulate long-term oxidative aging of alphalt binders. The only unit on the market that meets all ASTM and AASHTO standards.

FEATURES
  • The only PAV System on the market that meets all of the apparatus requirements. It delivers the dependable quality that your SHRP binder laboratory demands.
  • Hinged, bolted PAV cover and compact stainless steel cabinet --easy to maintain, fits against the wall or in a corner on your laboratory table -- even fits under overhead shelves!
  • System Controller provides automatic timing of the aging run and end-of-test shut-down. Displays critical data, and provides for faster stabilization of temperature after pressurization. Improved system performance and repeatability of results from elimination of some operator manual functions. Stores temperature and pressure data for later down-loading to a Windows equipped PC computer; can share computer with other laboratory equipment. Year 2000 compliant, the controller is available separately to upgrade older Model 9300 PAV Systems.
  • Precision stainless steel sample racks meet levelness requirements.
  • Energy Efficient -- no special wiring required; can run on optional back-up power supply during brief power outages [Prentex Model UPS-9300 provides approximately 30 minutes back-up power]. Draws a maximum of 525 watts during warm-up; less than 60 watts when at stable temperature. Very little heat load on laboratory's HVAC system. Available in 100-125 Volt , 10 Amp, 50-60 Hz ac and 208-252 volt, 5 Amp, 50-60 Hz ac versions.
  • Shipped Complete -- ready to connect to your wall electrical power outlet, standard bottled compressed air and PC computer.
  • ASME Code-stamped pressure vessel with hinged bolted cover, registered with the National Board of Boiler and Pressure Vessel Inspectors and designed for operation at up to 150 C and 2.45 MPa . Pressure vessels designed, manufactured and inspected to this standard are accepted in North America and many countries worldwide. The 100% stainless steel pressure vessel is supplied in accordance with lab safety recommendations for asphalt pressure vessel.
  • PAV temperature is maintained +/- 0.3 C ; pressure is maintained +/- 0.03 MPa during the aging period following stabilization within the allowable time* following pressurization.
  • Meets all AASHTO and proposed ASTM apparatus requirements regarding vessel dimensions, temperature and pressure control. Temperature and pressure data are controlled to tighter standards than required and are logged and stored in the System Controller for later downloading to user's PC-type Computer.
  • Ensures multiple levels of safety in both temperature and pressure control systems, preventing operation of the pressure vessel in excess of its design limits. European Community marked.
  • Air Supply -- a regulator and connecting hose for bottled industrial or breathable grade compressed air is included. [Compressed oxygen must not be used!] Overseas customers must furnish a suitable compressed air regulator.
  • Unsurpassed customer support. Telephone and FAX support for troubleshooting allow most problems to be corrected on-site by the user without necessitating a service call from an instrument repair company or shipment to the factory for repair.
  • Over 200 users on 4 continents agree that the Model 9300 is "User-friendly" and "Well-designed".
  • Space-efficient -- occupies only 650 mm x 430 mm (251/2" x 17") of counter space and requires only 790 mm (31") of overhead clearance. Weighs only 73 kilograms (160 pounds) -- normal laboratory counters and tables should provide adequate support.
  • The only PAV system on the market capable of operating on a standard computer back-up power supply during brief electrical outages!
  • Accessories -- available accessories include cover bolt wrench, calibration instruments [N.I.S.T. traceable], extra sample pan racks, sample pans, spare O-ring gaskets and more.
  • One-year parts and workmanship warranty (subject to terms and conditions stated in warranty -- see distributor for details).
  • Delivery -- Delivery time for individual orders is normally less than two months (F.O.B. Dallas, Texas).
