CI PBT 20 – Polymer Boiler Treatment for Scale Control in Industrial Systems
Polymer Scale Control for Higher-Pressure Steam Boilers and Industrial Systems
CI PBT 20 is the polymer-based scale treatment for steam boiler systems where phosphate chemistry is not the right fit. It is built for higher-pressure and industrial systems where operators want hardness control without adding phosphate loading to blowdown water or wastewater streams.
Its synthetic polymers condition calcium, magnesium, and other hardness minerals before they can crystallize into the deposits that coat tube walls, restrict flow, and choke heat transfer. Instead of relying on phosphate sequestration, CI PBT 20 keeps hardness dispersed and moving out through blowdown before it bakes onto hot metal surfaces.
Where CI PD90 is the phosphate scale-control option, CI PBT 20 is the polymer alternative for systems where phosphate use is restricted, undesirable, or operationally less attractive. The outcome is the same — hardness stays off the metal, heat transfer stays cleaner, and the boiler stays out of the acid-cleaning cycle longer.
CI PBT 20 is best suited to industrial steam systems that need scale prevention without phosphate chemistry. In practical terms, it helps reduce descaling frequency, preserve thermal efficiency, and support longer equipment life in boilers that run hard and hot.

Maintenance Value
Helps Reduce Descaling Frequency, Preserve Thermal Efficiency, and Extend Boiler Service Life Under Sustained High-Heat Operation
Regulatory / Use Boundary
Not Recommended for Direct Food-Contact Steam · Use PD90 Where Food-Contact Steam Requirements Apply
Operational Notes
• This is the phosphate alternative in the line — built for systems where hardness control is needed but phosphate chemistry is restricted or unwanted
• Instead of phosphate sequestration, synthetic polymers keep hardness from crystallizing into the deposits that coat tube walls and choke heat transfer
• Best used in higher-pressure or industrial steam systems where polymer conditioning is preferred over phosphate treatment
• Distinct from PD90: PD90 is the phosphate scale-control option; PBT 20 is the polymer-based alternative for different regulatory or operating constraints
• Designed to work alongside oxygen scavengers, dispersants, and corrosion inhibitors as part of a layered industrial boiler treatment program
• Same outcome, different mechanism: hardness stays off the metal and leaves through blowdown instead of baking onto hot surfaces
Practical Fit
CI PBT 20 is the scale-control option for industrial steam systems that need polymer performance without phosphate chemistry. It belongs where operators want to keep hardness off the metal, keep the boiler out of the acid-cleaning cycle longer, and control scale in a way that fits higher-pressure service or discharge-sensitive operation.
This block is built from the revised positioning you approved: CI PBT 20 as the polymer-based alternative to PD90 for steam boiler scale control where phosphate chemistry is not the right fit. The product is therefore positioned here for industrial systems that need hardness conditioning and dispersion without phosphate loading, while preserving the catalogue split that keeps PD90 as the phosphate scale-control option and PBT 20 as the polymer alternative.
