Ammonia refrigeration systems have become the industry standard for large-scale industrial and commercial cooling. Renowned for their energy efficiency, reliability, and environmentally friendly operation, ammonia-based systems are ideal for facilitzies requiring precise and large-scale temperature control, such as:
At TIESA, we design, install, and maintain custom ammonia refrigeration systems to meet the unique operational requirements of each facility. Our solutions deliver optimal energy efficiency, safety, and long-term performance, while also helping companies meet their sustainability objectives.
With rising energy costs and increasingly strict environmental regulations, ammonia refrigeration continues to be the preferred solution for industrial-scale, energy-efficient, and cost-effective cooling systems.
Ammonia refrigeration is a mechanical refrigeration process that uses anhydrous ammonia (NH₃) as the primary refrigerant. Ammonia is a naturally occurring compound with exceptional thermodynamic properties, making it highly effective at absorbing and transferring heat — a critical requirement for industrial cooling applications.
Unlike synthetic refrigerants, ammonia has:
Zero Ozone Depletion Potential (ODP)
Negligible Global Warming Potential (GWP)
This makes ammonia refrigeration one of the most environmentally sustainable and energy-efficient solutions for industrial operations, particularly in facilities with high cooling demand.
Ammonia refrigeration systems operate through a closed-loop cycle, designed to remove heat from a refrigerated space and release it into the environment. The cycle consists of four primary stages:
| 1. Evaporation | 2. Compression | 3. Condensation | 4. Expansion |
| Liquid ammonia enters the evaporator at low pressure. As it absorbs heat from the refrigerated space or product, it evaporates into a gas, producing the cooling effect. | The ammonia vapour is drawn into the compressor, where pressure and temperature are increased. This prepares the refrigerant to release the absorbed heat during condensation. | High-pressure ammonia vapour passes through the condenser, where it releases heat to the ambient air or water and condenses back into liquid form. | The liquid ammonia passes through an expansion valve, reducing its pressure and temperature before returning to the evaporator. This process allows precise and consistent temperature control, even in large industrial facilities, while minimizing energy consumption compared to synthetic refrigerants. |
Ammonia refrigeration systems are used across multiple industrial sectors where precise temperature control and high reliability are critical.
Temperature control is critical in food production to ensure safety, quality, and shelf-life. Applications include:
Ammonia systems allow rapid cooling, maintain consistent temperatures, and prevent bacterial growth, ensuring compliance with food safety standards.
Large cold storage and logistics warehouses rely on ammonia refrigeration for consistent temperatures across extensive areas. Benefits include:
Breweries, wineries, and soft drink plants rely on ammonia refrigeration to:
Ammonia systems provide high heat absorption rates, which is critical for liquid-based production processes.
Ammonia refrigeration ensures precise cooling for temperature-sensitive materials, including:
The reliability of ammonia systems ensures continuous, uninterrupted cooling, which is essential in regulated medical environments.
Industrial ice rinks, chemical processing plants, and specialty facilities benefit from ammonia’s:
With the rise of e-commerce, perishable food delivery, and pharmaceutical distribution, ammonia refrigeration is increasingly used in:
