Cooling Systems

Description

Corrosion, deposition, fouling, and biological growth can derail your operations. PWT combination of chemicals, industry expertise can help prevent these issues or aid in the recovery from a failure event .

• closed cooling system
  1. corrosion inhibitor based on nitrite (preservator)
  2. corrosion inhibitor based on molybdate
  3. corrosion inhibitor based on molybdate & nitrite
  4. corrosion inhibitor based on tannin
  5. corrosion inhibitor and antifreeze based on nitrite and glycol
  6. corrosion inhibitor and antifreeze based on nitrite and glycol
  7. acid cleaner
  8. alkaline cleaner
• one through cooling system
  1. corrosion & scale inhibitor
  2. oxidizing biocides
  3. non- oxidizing biocides
• open recirculation cooling system (evaporation cooling tower)
  1. Corrosion and scale inhibitor based on zinc and organophosphonate
  2. all organic corrosion and scale inhibitor
  3. bio dispersants
  4. oxidizing biocides :
