Advanced chemical solutions and monitoring services to prevent scaling, corrosion, biofouling and to maximize cooling efficiency and uptime.
Cooling water systems are the backbone of industrial heat rejection. Whether open recirculating (cooling towers), closed loops, or once-through, proper water chemistry is essential to maintain heat transfer efficiency, prevent asset damage, and ensure operational continuity.
Fouled heat exchangers consume more energy; clean surfaces reduce pumping and cooling load.
Corrosion and scale lead to tube failures, leaks, and costly unplanned downtime.
Stable water chemistry prevents biofouling, foaming, and carryover that disrupt operations.
CLEANFLO combines system diagnostics, tailored chemistry, and continuous monitoring to keep your cooling water systems running at peak performance.
Each problem left untreated directly impacts operating costs and equipment life.
Mineral deposits act as insulation, reducing heat transfer and increasing energy consumption by up to 15%.
Metal loss leads to leaks, equipment replacement, and contamination of process streams.
Slime and biofilm reduce flow, accelerate corrosion, and pose health risks (Legionella).
Excess foam causes water loss, chemical waste, and contamination of downstream equipment.
High velocities and suspended solids damage pumps, valves, and piping.
Targeted formulations designed for specific system conditions and performance goals.
Purpose: Prevent precipitation of hardness salts (calcium carbonate, calcium sulphate, silica).
Mechanism: Crystal modification and dispersion at sub‑stoichiometric levels.
Benefit: Maintain clean heat exchangers, reduce blowdown, and save water.
Monitoring: Hardness, conductivity, LSI/RSI.
Purpose: Protect metallurgy (mild steel, copper, stainless steel) from electrochemical attack.
Mechanism: Anodic/cathodic passivation or film formation (e.g., molybdate, azoles, phosphonates).
Benefit: Extends equipment life, reduces replacement capex.
Monitoring: Corrosion coupons, metal ion residuals (Fe, Cu).
Purpose: Control bacteria, fungi, and algae in cooling water.
Mechanism: Oxidizing (chlorine, bromine, chlorine dioxide) and non‑oxidizing (isothiazolinones, glutaraldehyde) with shock dosing.
Benefit: Prevent biofilm, reduce health risks, maintain heat transfer.
Monitoring: ATP, dip slides, residual biocide.
Purpose: Keep suspended solids, silt, and debris from settling.
Mechanism: Anionic or non‑ionic polymers that impart particle repulsion.
Benefit: Cleaner sumps, reduced fouling, effective blowdown.
Monitoring: Turbidity, suspended solids.
Purpose: Maintain optimal pH to minimize scaling and corrosion.
Mechanism: Acid or alkali dosing to keep LSI within safe range.
Benefit: Stable water chemistry, predictable performance.
Monitoring: pH, total alkalinity, LSI.
Purpose: Suppress foam caused by organics, surfactants, or high cycles.
Mechanism: Surface tension modifiers that collapse foam.
Benefit: Reduce water loss, prevent drift contamination.
Monitoring: Visual observation, foam height.
Purpose: Address unique challenges: closed‑loop oxygen scavengers, filming amines for condensate, polymeric cleaners for existing deposits.
Mechanism: Tailored chemistries for specific metallurgy and system conditions.
Benefit: Comprehensive protection beyond conventional programs.

Common monitoring parameters in cooling water programs
Challenge: A petrochemical plant faced frequent heat exchanger cleaning due to calcium carbonate scale, resulting in 15% efficiency loss and annual maintenance costs exceeding ₹25 lakhs.
Solution: Cleanflo implemented a customized scale inhibitor + dispersant program with online conductivity control, increasing cycles from 3 to 6.
Results: Heat transfer restored, makeup water reduced by 30%, and no unscheduled cleaning in 18 months.
