 Coooling Water Corrosion and Deposit Inhibitor

 
PRODUCT DESCRIPTION AND APPLICATION


Product Bulletin: 

3D TRASAR products are part of an innovative water treatment program that uses proven technology to prevent operational problems. 3D TRASAR technology compensates for both routine and special causes of system variation. 3D TRASAR programs provide a return on your investment through their unique control and diagnostic capabilities.

3D TRASAR 3DT128 technology is a multifunctional scale inhibitor for open recirculating cooling water systems. It is ideal for cooling systems with a long holding time index, and where iron and manganese dispersion is a limiting factor. Also, it is convenient where make-up water is high in phosphate concentrations

 The 3D TRASAR 3DT128 contains: 

  • Dual function phosphonate inhibitor for both cathodic (pitting) corrosion and calcium carbonate scale. The active material is a patented, proprietary Phosphinosuccinic Oligomer (PSO) and is resistant to reversion 
  • Orthophosphate inhibitor for anodic corrosion
  • High-Stress Polymer 2 (HSP2) dispersant. 
  • Blend of halogen-stable azoles for copper corrosion inhibition. 

3D TRASAR 3DT128 is designed for use in systems with recirculating water calcium concentrations between 50 and 1000 ppm (as CaCO3) at the targeted cycles when the pH is less than 8.7.

3D TRASAR 3DT128 programs contain no heavy metals such as molybdate or zinc and can be used in situations where heavy metals are limited by discharge regulations.

DOSAGE AND FEEDING: 

The dosage range for the 3D TRASAR 3DT128 program depends primarily on the hardness, alkalinity, phosphate content, and pH of the recirculating water. For complete dosage and feeding recommendations, contact your sales engineer. 

3D TRASAR 3DT128 technology should be fed via a closed feed system. A closed feed system is defined as a system in which fluid is moved from a closed storage vessel into a treated media without exposure to the atmosphere except through normal venting or pressure relief devices. 

3D TRASAR 3DT128 technology should be fed neat. Do not dilute the product or mix with other chemicals. Unstable reactions may occur that can deteriorate the product’s effectiveness. 

3D TRASAR 3DT128 technology must be fed continuously to assure adequate levels of chemical residuals are maintained at all times. Slug feeding must be avoided because it will result in periods of high and low levels of chemical residual. Underfeeding could lead to corrosion and scaling conditions. Excessive chemical levels can result in product precipitation. 

STORAGE: 

3D TRASAR 3DT128 should be stored in a location where the product temperature can be maintained between 22oF (-6oC) and 110oF (43oC). In cold climates, heat tracing and insulation of exposed containers and transfer lines may be necessary. If freezing occurs, the product is recoverable. Move product to a warmer area to thaw and agitate to mix. Do not store longer than one year. Refer to the Safety Data Sheet (SDS) for the most current data.
