Why it matters
Bacteria and organic deposits can lower heat-transfer rates up to 40%. JC 9465 helps prevent biofouling and scale, control biofilm and MIC, address Legionella in under 10 seconds, and eliminate zebra mussels.
The problem
On a heat-transfer surface, biofilm is roughly 300% worse than calcium-carbonate scale as an insulator. ASHRAE data shows a fouling factor of just 0.001 can cut cooling efficiency by about 10%. Beyond lost heat transfer, biofilm shields anaerobic bacteria against the water treatment program, driving pitting and microbially influenced corrosion (MIC) of the metal underneath.
The program
Instead of a stack of separate biocides, dispersants and scale inhibitors, the JC 9450 / JC 9465 program uses a single mineral-oxychloride chemistry controlled by oxidation-reduction potential (ORP). It controls biofilm, algae, scale and corrosion at once while improving heat transfer and lowering total cost.
Efficacy vs. ORP
| ORP (mV) | Surviving CFU / 100 mL | Status |
|---|---|---|
| +200 | 300 | Poor control |
| +300 | 36 | Partial |
| +400 | 3 | Improving |
| +600 | 0 | Disinfection |
| +700 | 0 | 6-log Legionella in <10 sec |
| +800 | 0 | Sterilization |
Legionella
Legionella thrives at 20–50°C (optimum 37°C) — the exact range of a warm cooling loop. Around 90% of Legionella lives inside biofilm (per Montana State University's Center for Biofilm Engineering), where it is more resistant and can harbor protective amoebae. A biocide that cannot break biofilm cannot reliably reach it.
Also controlled
JC 9465 delivers ozone-class oxidation but, unlike ozone, leaves a residual in the water. That residual carries control downstream of the injection point — where dissipating ozone cannot — to eliminate invasive zebra and quagga mussels in intake and cooling systems.
The same oxidative chemistry eliminates hydrogen sulfide in wet scrubbers, shifting ORP from reducing to oxidizing and converting H₂S to inert sulfates. See the Oil & Gas research page for the full H₂S wet-scrubber study.
Ozone must be generated on-site and dissipates within seconds of leaving the contactor. Mineral-oxychloride ROS delivers comparable oxidation potential with a measurable residual you can control by ORP — without dissolving a gas into the water.
Questions
On a heat-transfer surface, biofilm insulates about 300% worse than calcium-carbonate scale, and even a 0.001 fouling factor can cut efficiency roughly 10% (ASHRAE). Biofilm also shields anaerobic bacteria, driving pitting and MIC.
Holding ORP above +700 mV produced a 6-log Legionella reduction in under 10 seconds in Special Pathogen Laboratory testing, and eliminates legionellosis risk in most systems within four hours — because it breaks the biofilm where ~90% of Legionella hides.
Yes. The single mineral-oxychloride chemistry, controlled by ORP, addresses biofilm, algae, scale and corrosion together — while cutting electricity use 20%+ (per SCE) by keeping heat-transfer surfaces clean.
It provides ozone-class oxidation but leaves a residual, so control continues downstream of the injection point where ozone would have already dissipated.
