Exhaust Fired VAM Chillers: Transforming Waste Energy into Climate Solutions

Learn about Direct Fired Chiller | See VAM Product Page | CCHP Systems | Pump Solutions

Introduction:
Industries today face the challenge of reducing energy costs and emissions while maintaining high productivity. Cooling systems, essential in manufacturing, food processing, and pharmaceuticals, often consume large amounts of electricity. Exhaust Fired Vapor Absorption Machine (VAM) chillers turn a problem into an opportunity using waste exhaust energy to provide efficient, sustainable cooling.

How They Work:

Exhaust Fired VAM chillers use high-temperature exhaust gases from boilers or industrial processes to drive the absorption refrigeration cycle: The refrigerant (water or ammonia) absorbs heat from the process or space. It is absorbed by a solution (like lithium bromide) and then separated using exhaust heat. The refrigerant returns to continue the cycle. No compressors. Less electricity. Eco-friendly, continuous cooling.

Key Benefits:

• Energy Savings: Uses waste exhaust, cutting electricity consumption.
• Sustainable: Operates with natural refrigerants, reducing GHG emissions.
• Low Maintenance: Fewer moving parts, longer lifespan.
• Versatile: Suitable for HVAC and industrial cooling applications.

Real-World Impact:

Plants using Exhaust Fired VAM chillers convert waste exhaust into cooling, saving 50–70% on energy costs and significantly lowering CO₂ emissions.

Conclusion:
By harnessing waste heat, these chillers provide smart, sustainable, and climate-friendly cooling, helping industries operate efficiently and greener.
