Prevent Crystallisation & Corrosion in Your Absorption Chiller

Use our LiBr Concentration Calculator to estimate lithium bromide solution strength based on specific gravity measurements. This tool helps engineers, facility managers, and chiller technicians quickly evaluate LiBr condition, crystallisation risk, and stability in absorption chiller systems.

This calculator is part of Vamtec’s ongoing support for accurate LiBr analysis, preventative maintenance, and long-term absorption chiller performance.

Why LiBr Concentration Matters in Absorption Chillers

Lithium Bromide (LiBr) is the heart of every absorption chiller. Its concentration directly affects:

Cooling capacity
Energy efficiency
Corrosion risk
Crystallisation potential
Vacuum stability
Long-term system reliability

Even a small shift in LiBr concentration can result in:

❌ Crystallisation
❌ Corrosion inside the chiller and heat exchangers
❌ Reduced COP
❌ System shutdowns
❌ High operational costs

Our calculator helps detect these risks early — but only a full LiBr laboratory analysis can confirm the exact chemical health of your solution.

LiBr Concentration Calculator

The calculator estimates:

LiBr concentration (%)
Crystallisation risk levels
General solution stability

This gives you an immediate indication of whether your absorption chiller is chemically within safe operating range.

How to Use This Tool

Measure specific gravity of your LiBr solution using a calibrated hydrometer or density meter.

Enter the value into the calculator.

Receive an estimated LiBr concentration percentage.

Use the result to assess whether your system may require full LiBr analysis, dilution, inhibitor dosing, or further inspection.

What the Calculator Can Tell You — and What It Cannot

The calculator can indicate if your LiBr solution is:

Too concentrated (high crystallisation risk)
Too diluted (poor cooling performance)
Potentially unstable

But the calculator cannot detect:

Alkalinity
Inhibitor levels
Non-condensable gases
Corrosion by-products
Organic impurities
Internal chiller damage

These issues require a full Lithium Bromide Analysis, which Vamtec provides.

When You Should Request a Full LiBr Chemical Analysis

If your calculator result shows:

🔴 High concentration (crystallisation risk)

You may already be approaching a system failure.

🟠 Low concentration (dilution)

Your system is likely under-performing and consuming more energy.

⚠️ Unexpected or unstable readings

This suggests contamination, corrosion, or vacuum issues.

🟡 Values drifting month-to-month

A sign that internal conditions are deteriorating.
