Corrosion and scale inhibition
Product selection based on water chemistry, materials and operating conditions.
Discuss suitabilityCooling water
Stable cooling with control over corrosion, scale and microbiology.
Treatment programmes for open cooling systems, closed loops and critical heat exchangers.
System approach
Treatment tailored to your installation
An effective cooling-water programme maintains the balance between cycles of concentration, material protection, microbiological control and water consumption.
Signals to investigate
- Declining heat transfer
- Corrosion products or localised attack
- Deposits in pipes and heat exchangers
- Fluctuating conductivity or dosing
Available approaches
Integrated product, equipment and support
Closed-system protection
For selected closed loops containing steel, copper alloys or mixed materials.
Discuss suitabilityMonitoring & adjustment
Trend analysis, verification measurements and clear action limits.
Discuss suitabilityFilm-forming amines
Two product routes, each with its own function
The film-forming technology targets installation surfaces. Product selection, dosing and monitoring are tailored to water chemistry, materials, temperature, system volume and existing deposits.
MexProtect™ corrosion inhibitor
For a hydrophobic protective film on metal surfaces in selected open and closed industrial cooling circuits. MexProtect™ is marketed without a biocidal claim.
View the corrosion routeFilm-forming amine biocide
A separate biocide for selected industrial cooling-water systems where biofilm and biological fouling need to be controlled. Use only in accordance with the current authorisation and product label.
View the biocidal routeBaseline measurement and verification
We monitor corrosion coupons or LPR, iron and copper transport, pressure drop, filter loading, heat transfer and relevant microbiological parameters.

Make selection, dosing and performance verifiable
A treatment programme is complete only when it is clear in advance what is assessed, how it is applied and which measurements will be used to verify performance.
What we assess technically
- Water balance, cycles of concentration and variation in make-up and blowdown water
- Materials, heat load and local temperatures in critical heat exchangers
- Interaction between corrosion, deposits, suspended solids and microbiology
- Dosing, blowdown control, injection points, filtration and operational hygiene
What we monitor during operation
- Conductivity, cycles of concentration, pH, temperature, make-up and blowdown
- Product residual or tracer, actual pump output and inventory consumption
- Corrosion coupons or LPR, metal transport and visual inspections
- Microbiological indicators, pressure drop, filter loading and heat transfer
Frequently asked questions
Technical choices require system context
These answers provide initial direction. The final approach follows from the installation data and product documentation.
What is the difference between an open and a closed cooling circuit?
An open recirculating system loses water through evaporation and concentrates salts. A closed circuit exchanges far less water, but leakage, oxygen ingress and mixed materials remain relevant.
Can one chemical product solve every cooling-water problem?
Not reliably without a system assessment. Corrosion, scale, suspended solids and microbiology interact; cleaning, filtration or operational changes may also be required.
Does a biocide replace Legionella management for a wet cooling tower?
No. An authorised biocide may form part of the water-treatment programme, but it does not replace the risk assessment, management plan, checks and logbook required by the applicable rules.
