POLYTAN 4F is a blended liquid treatment based on organic tannin, polymer sludge conditioners and alkali. It can be used either by itself or in conjunction with other supplemental FEEDWATER treatments to give a balanced treatment programme. POLYTAN 4F does not add substantially to the boiler water TDS, and hence is an ideal treatment for boilers which are susceptible to foam formation.

POLYTAN 4F 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.

POLYTAN 4F is also suitable for boilers with copper components which makes it perfect for use in typical land, maritime and heritage steam boilers.

Suitable for

Steam boilers

High, Medium and Low temperature hot water closed loop systems
