What is an ammonia refrigeration system?
An ammonia refrigeration system is an industrial cooling system that uses ammonia (NH3) as the refrigerant, valued for its high efficiency, zero global warming potential, and zero ozone depletion potential.
How does ammonia refrigeration work?
The system compresses ammonia refrigerant, rejects heat through a condenser, reduces pressure through an expansion device, and absorbs heat through the evaporator to produce the required cooling effect.
What is the advantage of ammonia over synthetic refrigerants?
Ammonia offers superior energy efficiency, zero GWP and ODP, and lower running costs, particularly in large-capacity industrial applications.
What temperature range can Airtech ammonia systems achieve?
Airtech ammonia refrigeration systems are engineered to operate from standard cold storage temperatures down to as low as −50°C depending on process requirements.
Is ammonia safe to use in refrigeration systems?
Ammonia is a hazardous refrigerant requiring specialized design, installation, and maintenance. Airtech adheres to strict safety regulations and provides comprehensive operator training.
Which industries use ammonia refrigeration?
Industries include dairy processing, ice cream production, chemical processing, food processing, cold storage, and breweries.
What dairy applications use ammonia refrigeration?
Milk chilling centres, process cooling at dairy plants, milk cold rooms, blast rooms, cold storage, freezer rooms, and ghee granulation rooms.
What maintenance is required for ammonia systems?
Routine maintenance includes leak detection checks, compressor inspections, condenser cleaning, safety system testing, and refrigerant charge monitoring.
What capacity ammonia refrigeration systems does Airtech manufacture?
Airtech manufactures customized systems for a wide range of industrial cooling loads. Capacity ranges should be confirmed with the engineering team.
