Additive Injection Systems
Additive Injection Systems
How the System Works
Additive injection keeps a process stream within specification by continuously introducing small, precise amounts of catalyst, inhibitor or treatment chemical. A skid-mounted system provides a safe, calibrated injection point with back-pressure and check valves, protecting both the pump and the pipeline while holding tight dose accuracy.
Standard Configuration
- PE/PP/SS additive day tanks with level switches
- Diaphragm or plunger metering / injection pumps
- Back-pressure and check valves at injection point
- Flow, pressure and level transmitters
- PLC control cabinet with touchscreen HMI
Key Features
- High-accuracy, pulse-free injection
- Leak-safe with back-pressure protection
- Flow-proportional or analyser-trimmed dose
- Chemical-resistant wetted parts
- 4-20 mA / Modbus link to plant DCS
Typical Applications
- Pipeline and gathering-system injection
- Refinery and petrochemical additive dosing
- Polymer and catalyst addition
- Fuel and lubricant additive injection
- Water and process treatment injection

Our additive injection systems meter catalysts, inhibitors and process additives into flowing streams with high accuracy and no leakage.
Each skid is engineered in 3D and can be supplied with PLC automation and touchscreen HMI control, ready to run from day one.
