  • What is cooling tower scale?
  • Scale commonly forms on metal surfaces in towers from minerals such as calcium carbonate, calcium phosphate, magnesium silicate and calcium sulfate. Today we’ll cover how to perform a scale risk measurement assessment, basic chemical solutions, chemical free solutions, and advanced strategies for combatting cooling tower scale.
  • What is a cooling water corrosion inhibitor?
  • Two common cooling water corrosion inhibitors are nitrite and molybdate, as outlined below. Nitrite (NO 2), usually fed as sodium nitrite (NaNO 2), is an anodic inhibitor by virtue of the chemical reaction with iron hydroxide at anodes. Sodium nitrite is an inexpensive and safe chemical to handle.
  • What is phosphate based corrosion and scale inhibitor?
  • Phosphate based corrosion and scale inhibitor for low hardness. Very good at high temperatures. Zinc based multi-functional corrosion and scale inhibitor and bromine precursor. For soft to medium hardness waters. Blend of organic inhibitors for use where heavy metals or phosphates are restricted. For medium to high hardness waters.
  • Why do cooling towers have scale?
  • Scale is enemy #1 that often constrains cooling towers from being able to operate safely at higher cycles of concentration. Scale commonly forms on metal surfaces in towers from minerals such as calcium carbonate, calcium phosphate, magnesium silicate and calcium sulfate.
