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

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
