The Scale Problem: 2 Million Search Results Can't Be Wrong
An online search for "how does mineral scaling impact cooling towers" will yield over 2 million results. The severity of mineral buildup in cooling tower equipment and their components is a substantial and serious maintenance issue that costs facility owners millions annually.
7-12%
Energy increase per 1mm scale [1]
30-50%
Blowdown increase from scale [2]
$400K
Single facility savings [3]
When facility managers search for answers, they find phrases like these repeated across thousands of technical articles and industry publications:
"Drastically reduces normal heat exchange levels"
"Reduces efficiency, increases corrosion risk, and damages equipment"
"Scale deposits significantly impact efficiency, increase energy consumption, and lead to equipment failure"
These are all commonly known issues in maintaining these expensive building support systems. Yet most facilities continue to rely on outdated chemical treatments that only address the symptoms—not the root cause.
Researched Impacts:
- 1 mm of scale buildup = 7-12% increase in energy demands [4]
- Scale acts as thermal insulation—forcing chillers to work harder, longer
- Increased blowdown = wasted water and higher sewer costs
- Scale-protected biofilm creates Legionella risk


Using Chemicals to Descale Cooling Towers: Is That Really the Best Answer?
If your thought process goes to "chemical treatments have been used for decades, so what's the problem?"—let's examine what that actually means for your facility.
The Chemical Approach:
You are passing an acid (or variation thereof) through your equipment. Acids descale minerals because they also corrode metal. It's a delicate balance—enough time to dissolve scale, but not enough to destroy your equipment.
The Chemical Process
- Hours of downtime
- Acid injection into building water lines
- Precise timing—too little won't work, too much damages equipment
- Massive water flushing to remove chemicals
- Chemicals discharged into municipal water systems
- Scale returns—repeat cycle in 3-6 months
The Vulcan Approach
- Zero downtime
- No chemicals, no acid, no PPE
- Set it and forget it—no timing required
- No water waste, no chemical discharge
- Permanent scale prevention
- Install once, protect forever
You Could Just Use the Vulcan Descaler

Scale Is Part of a Much Larger Problem
Mineral scale issues in cooling towers are about more than maximizing equipment efficiency.
Waterborne pathogens use mineral scale buildup as a breeding ground and food source.
The Hidden Danger:
Scale creates the perfect environment for biofilm and Legionella to thrive.
CDC Guidelines on Scale Control:
"Scale, corrosion, sediment controls, and system cleaning are critical for cooling tower operations and Legionnaires' disease prevention."
The Scale-Pathogen Connection
- Rough scale surfaces trap organic matter, feeding bacteria
- Biofilm forms on scale, protecting pathogens from disinfectants
- Legionella thrives in warm cooling tower water
- Scale insulates surfaces, allowing bacteria to survive
CDC: Cooling towers are a primary source of Legionnaires' disease outbreaks
The Vulcan Solution
- Eliminates scale — removes biofilm habitat
- Smooth surfaces — pathogens have nowhere to hide
- Zero chemicals — no discharge, no hazards
- 40+ years proven — 70 countries worldwide
