Corrosion & Scale Inhibitor Dosing

How the System Works

Corrosion and scale inhibitors protect heat exchangers, pipes and boilers from metal loss and mineral deposits that raise energy use and cause failures. A dosing system holds inhibitor concentration in the optimal range using analyser feedback and flow-proportional control, extending asset life and cutting maintenance.

Standard Configuration

PE/PP day tanks with agitators and level switches
Diaphragm or plunger metering pumps
pH and conductivity analysers
Static mixers and calibrated injection points
PLC control cabinet with touchscreen HMI

Key Features

Closed-loop inhibitor concentration control
Flow-proportional feed with analyser trim
Multi-point injection for large systems
Low-level, leak and pump-fault alarms
4-20 mA / Modbus link to plant DCS

Typical Applications

Cooling tower and chiller loops
Boiler feed and condensate systems
Closed heating and process loops
Oil refinery and petrochemical utilities
Paper, textile and food process water

Our corrosion and scale inhibitor dosing systems add film-forming and threshold inhibitors to keep metal surfaces protected and scale-free.
Each unit is engineered in 3D and can be supplied with PLC automation and touchscreen HMI control, ready to run from day one.
