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

Onguard 3 S § Onguard 3 S analyzer directly measures very low levels of scale/fouling build-up § Onguard 3 S allows differentiation between inorganic (scaling) and organic (fouling) deposits § Onguard 3 S is easily installed at all kinds of critical areas (pipes, heat exchangers, etc. ) § Onguard 3 S 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 3 S ensures system cleanliness that results in improved heat transfer efficiency and reduced energy consumption 6 D.

Sonoxide § Ultrasonic water treatment system for microbiological control 7 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 8 D. Oblassnig

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