ThermoClean CPX: Dual-Action Antimicrobial and Corrosion Protection for Circulation Systems
ThermoClean CPX is a high-performance universal stabilising concentrate engineered specifically for water baths, recirculating chillers, and complex water circulation systems. Unlike standard biocides, CPX provides a sophisticated dual-action defence: it eliminates the risk of microbial contamination while simultaneously providing advanced corrosion protection for internal components. This makes it an essential maintenance reagent for protecting high-value laboratory infrastructure, from simple heated baths to sensitive electron microscope cooling circuits.
The technical foundation of ThermoClean CPX is its ethandiol-based formulation, which functions similarly to alcoholic disinfectants to suppress the growth of bacteria, viruses, fungi, and algae. Crucially, it contains a proprietary blend of inhibitors that safeguard non-ferrous metals—including aluminium, copper, brass, and bronze—against oxidative degradation and pitting. The inclusion of a blue pH indicator allows for effortless monitoring; a visible fade in colour provides a clear signal to laboratory personnel that the active compounds have been depleted and the system requires replenishment.

Key Benefits:
- Universal Multi-Metal Protection: Extends equipment lifespan. Specifically formulated to prevent corrosion in systems containing aluminium, copper, and various alloys, preventing costly leaks and component failure.
- Broad-Spectrum Efficacy: Comprehensive microbial control. Effectively prevents the establishment of algae, bacteria, and endospores that cause blockages and “cold zones” in circulation lines.
- High-Efficiency Dilution: Economical 0.1% ratio. A single 100ml bottle treats 100 litres of water, offering a cost-effective solution for large-volume industrial and research cooling systems.
- Non-Volatile & Non-Foaming: Optimal for high-flow systems. Designed to operate without foaming even under heavy circulation, and remains non-volatile to ensure no hazardous residues or vapours are produced.
- Visual Indicator System: Simple maintenance monitoring. The blue-tinted indicator provides an immediate visual check of reagent activity, ensuring your systems are never left unprotected.
Technical Insights
ThermoClean CPX is designed for use in all thermostats and circulation pumps made of water-resistant metals, glass, or ethylene-glycol resistant plastics. Regular monthly re-dosing at 50% volume is recommended to maintain peak corrosion inhibition and sterility.
