Automated Air Release Value Analyzer

Koehler Instrument Company, Inc. (USA) is pleased to announce our new K88530 / K88539 Automatic Air Release Value Analyzer. This innovative instrument is commonly used to determine the ability of a turbine, hydraulic or lubricating oil to separate entrained air. This is a key performance characteristic in applications where agitation causes a dispersion of air bubbles in the oil. In order to discern air release properties, the sample is heated to a specified test temperature and blown with compressed air. After the air flow is ceased, the time required for the air entrained in the oil to reduce in volume to 0.2% gives you the air bubble separation duration.

Key features include an integrated touch screen control panel, which guides the user from start to finish of the test operation, and provides density calculation and timing operation for measuring the air release value of the test sample. A drying oven is available as a supplemental accessory for warming test oil at temperatures of up to 100°C. Also included, is an Integrated circulating bath and balance, and air bath for sinker. Safety features consist of compressed air heater overtemperature and overpressure protection circuitry. The instrument also automatically measures the time for air release for maximum convenience and reliability.

The Koehler Automatic Air Release Value Analyzer conforms to ASTM D3427, IP 313 and related specifications. An integrated touch screen aims for maximum ease of use. Automated features include an automatic lift system that moves the test vessel from air source to balance sinker and an automatic calculation of final sample density for determination of air release value. Other state-of-the-art features include an integrated circulation bath with water level indicator, integrated balance, secure clamp mechanism of the air tube and automatic jacketed test vessel draining.
