What Is a Vapour Absorption Machine?

A vapour absorption machine (VAM) is a non-electric refrigeration system that uses heat instead of electricity—perfect for turning waste energy into clean cooling.

Types of Systems That Fall Under VAMs

• - Vapor Absorption Chillers (VACs)
• - Steam Absorption Chillers
• - Hot Water Absorption Chillers
• - Exhaust Absorption Chillers
• - Direct-Fired Vapor Absorption Chillers

How Does a VAM Work?

1. Cooling Phase: Heat evaporates the refrigerant.
2. Absorption Phase: Lithium bromide or ammonia absorbs the vapor.
3. Separation Phase: Heat separates the refrigerant again.
4. Recycling Phase: Condensed refrigerant restarts the cycle.

Key Advantages of Vapour Absorption Machines

• Lower Energy Use: Runs on heat, not electricity.
• Eco-Friendly: No synthetic refrigerants or ozone damage.
• Quiet Operation: Minimal mechanical noise.
• Cost Savings: Low bills, long lifespan.
• Low Maintenance: Fewer parts to repair or replace.

Industries Benefiting from VAMs

• - Power Plants (Turbine Inlet Cooling)
• - Manufacturing Facilities (Waste Heat Use)
• - Malls, Offices, Hotels (Low-noise Cooling)
• - District Cooling Systems

The Takeaway: Cool Smarter with VAMs

VAMs help businesses reduce energy use, emissions, and costs by transforming available heat into sustainable cooling. With BROAD absorption chillers, your operations stay green, quiet, and efficient.
