The following products for treatment and protection of cooling towers and other open systems are available:
Boiler scale prevention in closed systems by means of organophosphates.
Protection against organic contamination (e.g. oil, dirt particles etc.) by effective and lasting dispersion.
Boiler scale prevention in closed systems by dispersion and complexation, by means of specialised polycarbonic acids, N- and P-free
Neutral adjusted boiler scale prevention agent, stable against hydrolysis over a wide pH and temperature range – with concurrent good corrosion protection, and with integrated disinfectant effects.
Basically a disinfectant, but which concurrently commands over excellent hardness stabilizing and dispersing qualities – especially for air conditioning units, or even humidifiers.
Hardness stabilizer and disinfectant for fighting algae and scale deposition – especially created for ornamental fountains (e.g. indoor fountains).
Protection against formation of boiler scale, even under difficult conditions (e.g. a temperature range exceeding 100°C), simultaneously reducing corrosion as well.
Security for iron, steel, copper and non-ferrous metals, based on cyclic amines, for nonaqueous systems too (e.g. antifreezing agents or hydraulic fluids).
Protection by means of a combination of specialised corrosion inhibitors for all metal used in closed cooling circiuts, favored scope of application at higher temperature ranges.
Corrosion and scale prevention agent for closed cooling systems, based on molybdates.
Corrosion and scale prevention agent for closed cooling systems, based on phosphates and sulfite as an oxygen scavenger, including a biocide for fighting microbes; can be used in cold water as well as in warm water systems.
Hardness stabilizer especially for cooling circiuts, for which only hard raw water is available – possibly a water hardness up to 60°dH can be stabilized; acts even as a corrosion inhibitor, at higher dosing quantities.
Protection via a combination of phosphonic acids and specialised corrosion inhibitors for iron and aluminium; that means hardness stabilization and corrosion protection for alkaline waters without deposition of calcium phosphonates.
Neutral adjusted boiler scale prevention agent, stable against hydrolysis over a wide pH and temperature range (even at temperatures of more than 100°C) – with concurrent good corrosion protection, and with integrated disinfectant effects, even in the presence of chlorine and bromine, or chlorine dioxide.
An organophosphate combined with a dispersant, especially for semi-open cooling circuits, particularly at higher pH values; very advisable for partly softened raw waters too.
Zinc containing organophosphate for boiler scale prevention and corrosion protection; works even in the presence of chlorine and bromine, or chlorine dioxide, without any interference.
