PRODUCT DATA SHEET
Mexel®432 Performance Emulsion.
Mexel®432 is a proprietary filming polyamine that acts as a surface-active agent. It is assessed for cooling-water systems where surface condition, fouling behaviour and site chemistry need a structured review.

What Stations Actually Buy
Mexel®432 is supplied as part of a practical station package: the consumable emulsion, a controlled dosing arrangement, and the records needed for baseline review. Performance conclusions remain tied to site data, not generic savings claims.
Cooling-water application context
A station-specific review of condenser, cooling-tower or exchanger conditions before dosing scope is agreed.
Mexel®432 consumable supply
Bulk emulsion supply with dosing rates, storage notes and SDS/TDS documentation for the site team.
Traceable dosing records
Logged dosing events that can be compared with TR, TTD, vacuum and chemistry indicators during review.
Mechanism of Action
Mexel®432 is designed around surface interface activity rather than default bulk-water dosing. Site results still need to be verified against baseline data.
Dispersant Action
Helps reduce adhesion of suspended solids and biological matter on heat-transfer surfaces.
Corrosion Inhibition
Forms a hydrophobic film intended to support corrosion-control objectives.
Scale Control Review
Can be assessed as part of a scale-control program where site chemistry supports the approach.
Automated Dosing Hardware.
Precision control is the difference between "chemical dumping" and engineering. Our skid-mounted systems use logged dosing events and configurable controls, reducing unnecessary chemical use while keeping performance claims tied to site data.

Application & Dosing Protocols
Mexel®432 is applied via pulsed dosing rather than continuous feed, targeting the surface interface while keeping dosing volume traceable for review.
Typical Dosing Parameters
| System Type | Dosing Rate |
|---|---|
| Once-Through (Power Station) | 3-5 ppm, 20-30 min/day |
| Recirculating Cooling Tower | 5-8 ppm, 2-3 pulses/day |
| Closed Loop (HVAC) | 10-15 ppm, weekly maintenance |
TES IoT Integration
1
Automated Dosing Skid
TES Thingy:91 skid controls dosing timing and volume precisely, logging all events for later review.

Compatibility
Can be assessed alongside existing treatment programs where the station chemistry team requires compatibility review.

No Shutdown Required
The preferred dosing point is reviewed during scoping. Online installation or a short outage depends on site access and operating constraints.

Environmental Profile
Biodegradability
Supporting environmental documents are available for technical review. Site use must follow the latest SDS and local discharge requirements.
Toxicity (LC50)
Toxicity and discharge implications must be checked against the latest SDS, dosing plan, and site-specific discharge limits.
*Always refer to the latest Safety Data Sheet (SDS) for site-specific compliance.
Performance Validation Data
Mexel®432 performance is reviewed using ASME PTC 12.2 methodology where applicable. TTD, TR and back-pressure trends are compared against baseline data before any heat-rate or MW impact is discussed.
TTD Reduction
Site-specific
Terminal Temperature Difference is reviewed against a baseline and matched operating conditions
Vacuum Improvement
Measured
Condenser back-pressure is assessed at matched load conditions where data quality allows
Heat Rate Recovery
Derived
Heat-rate or MW impact is calculated from verified thermodynamic indicators
How Mexel®432 Differs From Conventional Programs
Mexel®432 is positioned as a surface-active, film-forming chemistry. Whether it replaces or complements an existing program depends on site chemistry and permits.

Technical FAQ
Common questions from station engineers and chemists.
Does Mexel®432 work with seawater?
Mexel®432 can be assessed for seawater cooling applications. Site use must follow the relevant environmental approvals, discharge limits and SDS guidance.
Is it compatible with Admiralty Brass tubes?
Compatibility should be confirmed against the latest TDS/SDS and the site materials list before dosing.
What if TTD doesn't improve after dosing?
High TTD is not always fouling. Our verification protocol includes a baseline phase to rule out non-fouling issues (air ingress, passing valves, mechanical problems) before dosing begins.
Can I use it alongside my existing anti-scalant?
Mexel®432 can be assessed as an alternative to parts of an existing program or integrated where compatibility allows. The station chemistry team should approve any change.
How quickly will I see results?
Timing depends on baseline stability, fouling severity, dosing access and operating conditions. Results should be judged from matched site data.
