Pressure Aging Vessel (PAV) 9500 FEATURES

The PAV 9500 is a sure performer in the binder aging process. Fully automated, easy to use, and energy efficient, the PAV 9500 is designed to provide precise results every time.


Sturdy and Well Designed Structure

The structure of the PAV9500 is just one factor that contributes to the efficiency and productivity of the system.


Features include:

  • A 100% stainless steel pressure vessel, ASME Code stamped and registered with the National Board of Boiler and Pressure Vessels.
  • A touchscreen control panel for easy operation with a minimum of input required.
  • A hinged and bolted PAV cover and compact stainless steel cabinet designed to fit against the wall, or in a corner, and/or under overhead shelves.
  • Precision stainless steel sample rack with a set of 10 precision spun sample pans.
  • Space Efficiency: the PAV9500 occupies only 650 mm by 430 mm of space and requires only 790mm of overhead clearance.
  • Light Weight: the PAV9500 weighs under 180 pounds so it can sit on a standard laboratory countertop (Does not require special low bench).


Energy Efficient

The PAV 9500 operates using almost any standard electrical supply and is so efficient that it actually saves energy.


  • Requires no special wiring
  • Draws less than 525 watts during warm up and less than 60 watts of electricity when at a stable temperature.
  • Is available in 100-125 volt, 10 Amp versions and 208-252, 5 Amp versions
  • Is the only PAV system available that can operate with a standard low cost back up supply during a power outage.


Safe and Supported

The PAV 9500 system meets all suggested safety requirements and is easy to maintain, especially with our customer support policies.

  • Meets all AASHTO R28, ASTM6521 and EN14769 apparatus requirements
  • For safety the PAV 9500 cannot operate in excess of its design limits
  • Is supported by both telephone and email/fax so most problems can be easily corrected on-site.
  • Comes with a one-year parts and workmanship guarantee


PAV 9500 PRODUCT DESCRIPTIONThe Prentex PAV 9500 performs accelerated aging of asphalt binder samples. It will give you the best results while saving time and aggravation. It’s easy-to-use design and space-saving construction makes the PAV 9500 the best return on investment available. As an ASME pressure vessel designer, Prentex designed the PAV 9500 with your safety in mind.

Made out of 100% stainless steel, the PAV 9500 is one of the most durable systems available. The pressure vessel meets standards accepted worldwide. Space and energy efficient, the PAV 9500 operates from a standard 100 to 125 volt, 10 Amp outlet or from a 208 to 252 volt, 5 Amp outlet. Weighing just under 180 pounds, the PAV 9500 can be stored on any laboratory table top, and even under overhead shelving.


The PAV 9500 is well supported with a one-year warranty on parts and workmanship. Additionally, an economical back-up power supply, calibration kit/tools, and other instruments to maintain the unit and perform normal operations are available from Prentex


The PAV 9500 is also designed for modular access and replacement when technology enhancements are due. The 9500 is the 2nd generation of Prentex PAV’s – the original was the very popular PAV9300 designed and manufactured under contract to the Federal Highway Department in 1992-93. After 20 years of unparalleled success, Prentex continues to lead the market with quality fabrication, compact design and efficient results.
