A Smarter Way to Cool: Why More Businesses Are Choosing Vapor Absorption Chillers

As energy prices soar and sustainability becomes critical, vapor absorption chillers (VACs) are replacing traditional, energy-hungry systems across industries.

How Do Vapor Absorption Chillers Work?

Instead of using a compressor, VACs operate through a thermodynamic cycle powered by heat:

• - Heat from natural gas, steam, or diesel turns water into vapor.
• - Lithium bromide absorbs the vapor.
• - More heat separates the mixture, restarting the cycle.

Why They’re Better Than Traditional Chillers

• Lower Electricity Bills: Uses waste heat, not grid electricity.
• Environment-Friendly: Reduces emissions and supports decarbonisation.
• Low Maintenance: No moving parts, fewer breakdowns.
• Quiet Operation: Ideal for hospitals and offices.

VAMs vs VACs – What’s the Difference?

VAMs: General term for all absorption-based systems. VACs: Specialized for chilled water cooling only.

Types of Non-Electric Chillers

• - Steam Absorption Chillers
• - Hot Water Chillers
• - Exhaust Absorption Chillers
• - Flue Gas Recovery Chillers
• - Direct Fired Vapor Absorption Chillers

Where You'll Find These Chillers
