Description
PT4F / AT-2320 is a high performance multifunctional tannin, combined scale and corrosion inhibitor for closed heating systems & boilers
PT4F / AT-2320 comprises a multi-treat blended liquid formulation based on organic tannin, polymer sludge conditioners and alkali.
PT4F / AT-2320 can be used either by itself or in conjunction with other supplemental treatments to give a balanced treatment programme.
PT4F / AT-2320 does not add substantially to the closed system water alkalinity and is ideal treatment in boilers which are susceptible to foam formation.
PT4F / AT-2320 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 in boilers.
Product Benefits
- Excellent tannin based scale and corrosion inhibitor for closed loop systems.
- Does not add substantially to water alkalinity.
- Ideal for boilers susceptible to foam formation.
