Waste Heat Recovery and the Benefits of Using Ammonia Water Absorption Refrigeration- Producing Cold from Hot

Sep-Pro specializes in creating solutions for generating refrigeration from low-grade waste heat recovery through the application of a chemical heat-transfer technique known as Ammonia Water Absorption. Believe it or not, water-ammonia systems actually use heat to produce cold.

With the ongoing rise in the cost of electric power, Ammonia Absorption Refrigeration (AAR) is becoming more widely used in natural gas plants, food processing factories, and many other industries. The primary benefit of using Ammonia Water Absorption Refrigeration is that waste heat is used instead of mechanical compression equipment that uses an enormous amount of electricity. The many other benefits of using AAR include:

Ammonia Water Absorption Refrigeration Conserves Energy

• AAR is an ideal fit with integrated energy and cogeneration systems
• AAR is the best choice for refrigeration when low cost steam or heat is available from other energy production process like biomass, coal, and renewable sources

Ammonia Water Absorption Refrigeration is Better For The Environment

• AAR earns carbon credits, reduces CO2 emission taxes, and promotes sustainable development initiatives
• Ammonia is one of the most eco-friendly refrigerants available
• Replaces hazardous ozone-depleting CFC refrigerants

Ammonia Water Absorption Refrigeration Reduces Operation and Maintenance Costs

• Modular construction minimizes installation time and costs
• AAR systems have only one moving part- resulting in negligible required maintenance
• Fully automatic and simple to operate with PLC controls
• Wide operating range, down to -40 degrees C

Ammonia Water Absorption Refrigeration is More Dependable

• Long useful life of at least 25 years. Many plants operate for 40 years and more
• Low dependence on availability of electricity
• Near design efficiency, even when operating at part load as low as 30% of design refrigeration load
• Standard capacities range from 5 – 1,000 tons of refrigeration
