5 D. Oblassnig Onguard 3S  Patented, innovative and powerful scale/fouling analyzer based on a unique ultrasonic measuring principle -Performance measurement instead of traditional product control

6 D. Oblassnig Onguard 3S  Onguard 3S analyzer directly measures very low levels of scale/fouling build-up  Onguard 3S allows differentiation between inorganic (scaling) and organic (fouling) deposits  Onguard 3S is easily installed at all kinds of critical areas (pipes, heat exchangers, etc.)  Onguard 3S allows long-time as well as short-time observations, due to its high test frequency (142 measurements per second) and its high sensitivity (resolution of 1 µm).  Onguard 3S ensures system cleanliness that results in improved heat transfer efficiency and reduced energy consumption

7 D. Oblassnig Sonoxide  Ultrasonic water treatment system for microbiological control

8 D. Oblassnig Sonoxide  Sonoxide ultrasonic water treatment system is a patented, revolutionary, mechanical alternative to conventional (chemical) microbiological control treatments  Sonoxide utilizes ultrasonic energy generated at low power and at high frequency to destroy or severely impair bacteria in the water, thereby preventing the bacteria from producing biofilm-forming polymeric material  Sonoxide effectively controls bacteria, algae and biofilm in water systems  Sonoxide reduces microbiologically induced corrosion  Sonoxide reduces energy consumption via improved heat transfer efficiency

9 D. Oblassnig Summary  Ashland’s unique technologies ensure -increased production capacity -increased quality of produced goods -increased profit by avoiding unplanned plant shut- downs -increased lifetime of equipment -decreased energy consumption/costs -decreased chemical consumption/costs -decreased costs for service and maintenance -decreased risk for people and environment
