B091M PAV  - PRESSURE AGEING VESSEL Code : Standard Method : EN 14769 | ASTM D6521 | AASHTO R28   PAV to simulates in-service oxidative aging that occurs in asphalt binders during service after 5 to 10 years (long-term aging). The sample is exposed to high pressure and temperature for  20 hours (selectable up to 99). The Pressure Ageing Vessel (PAV) features 100% compliance with the laboratory standards related to aging the bitumen. The unit consists of a stainless steel vertical pressure vessel (AISI 304 with ASME and CE certifications) enclosed in a cabinet with encased band heaters. A source of compressed air with a pressure of at least 2.1 MPa and a pressure regulator generates and maintains the aging condition required. MAIN FEATURES Sturdy stainless steel frame and vessel. Fast pre-heating system selectable up to 60 °C in order to reduce the conditioning time. Timer for setting time and date to start the machine at the desired time. Innovative cooling system. Fully automatic, Semi-Automatic and Manual tests. Temperature and pressure monitored in real time. Integrated 7’ colour Touch screen controller. Pressure monitored in real time by transducer and controlled to 2.1 ± 0.1 MPa. CE and ASME certification. The unit is equipped with a 7’’ colour Touch screen controller with front panel user interface with easy to use step-thru operation. The user-friendly software allows the operator to carry out the test in different modes: - AUTOMATIC: It’s possible to select from 4 different temperatures (85, 90, 100, 110 °C) and 2 different testing time (20 or 65 hours). - SEMI-AUTOMATIC: It’s possible to select a temperature from 60 to 120 °C and run the test for 20 or 65 hours as in the automatic mode; - MANUAL: This mode can be used in research and it allows to manually select the temperature from ambient to 130 °C and the testing time from 1 to 99 hours. Temperature and pressure can be monitored in real time, thanks to a platinum RTD probe and a pressure transducer. Data logs of both temperature, aging time and pressure are saved on USB stick at the end of the test. A pre-heat mode allows to reach a maximum of 60 °C before introducing the sample in safety conditions reducing the conditioning time of the sample that can reach faster the test temperature. Thanks to an innovative heating system and the pre-heating mode the test can start in around 1 hour. The instrument is supplied complete with a sample rack for the simultaneous testing of ten specimens, ten specimen pans as per standards, but without compressed air source, 2.1Mpa minimum pressure. TECHNICAL SPECIFICATION Operating pressure: 2.1 ± 0.03 Mpa (304 psi) Programmable temperature range: from ambient temperature to 130 °C, res: ± 0.1 °C Programmable pre-heating function: up to 60 °C Test temperature uniformity: ± 0.5 °C Testing time: up to 99 hours Safety equipment in all test conditions: Over pressure relief valve and Over temperature limit switch. Power supply: 110 - 230V 1Ph 50-60Hz 10A Dimensions: 450x650x500 mm approx. Weight: 80 Kg approx.
