POLYTAN 4C is a blended liquid treatment based on organic tannins, polymer sludge, conditioners and alkali. POLYTAN 4C can be used with softened or moderately hard make-up, and in many instances provides a complete balanced treatment by itself. However POLYTAN 4C can be used with other widely used conjunctional treatments to provide phosphate control and condensate system protection.

POLYTAN 4C controls corrosion by the dual mechanism of oxygen scavenging and the formation of a corrosion resistant tannate film. It prevents scale formation by converting residual hardness salts to a mobile non-adherent sludge that can be removed by blowdown.

Product Usage

POLYTAN 4C should be dosed initially at 1:1000, based on the system volume. The ongoing dosages should be made to maintain a tannin reserve of 12-20, and the appropriate pH and alkalinity residuals.

The actual dosage required depends on such variables as make-up water temperature, hardness and TDS and can be advised by your FEEDWATER CONSULTANT.

Analysis of your Tannin levels can be performed using our Tannin Titration Reagent Pack

Suitable for

Steam boilers only

(See Polytan 4F for Closed system treatment) – Recommended for boilers containing copper.
