Why Ammonia Chiller Are Dominating Large Scale Cooling Projects 

From cold storage to heavy process industries, ammonia screw chillers are setting the benchmark for high-capacity, energy-efficient industrial cooling. 

Large industrial facilities today face a very different cooling challenge compared to smaller commercial sites. Continuous production, higher heat loads, and strict temperature control mean that cooling systems must be powerful, reliable, and built for long-term operation. 

This is one of the main reasons why ammonia chiller manufacturers are playing a growing role in large-scale cooling projects. Ammonia-based systems, combined with screw compressor technology, are designed to handle heavy-duty industrial requirements while delivering high energy efficiency and long service life. 

From cold storage and food processing to chemicals and pharmaceuticals, ammonia screw chillers are increasingly seen as the backbone of large industrial refrigeration and process cooling. 

Why Is Ammonia the Preferred Refrigerant for Large Cooling Projects? 

Ammonia has long been recognised as one of the most efficient refrigerants for industrial applications. Its excellent thermodynamic properties allow for efficient heat transfer, which means large amounts of heat can be removed with lower energy input. 

Another key advantage is sustainability. Ammonia is an environmentally responsible refrigerant with no ozone depletion potential. This makes it a future-ready choice for industries that want to reduce environmental impact while maintaining high cooling performance. 

For large plants that operate around the clock, ammonia also offers strong cost advantages over the long term. Lower refrigerant charges, high efficiency, and proven industrial acceptance make ammonia a natural fit for large refrigeration systems. 

This is why many ammonia chiller manufacturers continue to focus on ammonia as a core solution for industrial-scale cooling. 

How Do Screw Chillers Support High-Capacity, Continuous Operation? 

While ammonia provides refrigerant efficiency, it is the compressor technology that determines how well a system handles large and continuous loads. This is where screw chillers become critical. 

Screw chillers use two helical rotors to compress the refrigerant gas. This design delivers nearly constant flow performance, which is ideal for industrial environments where cooling demand remains steady for long periods. 

Compared to other compressor types, chillers with screw compressors are well suited for high-capacity systems. They offer smooth operation, stable performance, and the ability to handle varying loads without frequent start-stop cycles. 

At Refcon, we manufacture and supply screw chillers with single and twin screw arrangements, allowing us to match the system design to the exact capacity and application needs. This flexibility helps ensure that large plants receive cooling systems built for their real operating conditions. 

Water Cooled vs Air Cooled Screw Chillers for Industrial Scale 

Large cooling projects often require careful selection between water-cooled and air-cooled screw chiller configurations. Both are part of Refcon’s product range and are designed to support different site and process requirements. 

Water Cooled Screw Chiller Systems 

For most heavy industrial applications, a water cooled screw chiller is the preferred option. These systems remove heat using water circulation, which allows for better control of condensing temperatures and improved overall efficiency. 

Water-cooled screw chillers are especially effective in large plants where cooling is required continuously. They are commonly used in: 

• Pharmaceutical manufacturing 
• Chemical processing plants 
• Data centres 
• Large centralised HVAC systems 
• Temperature-sensitive production environments 

A water cooled screw chiller delivers consistent performance in demanding industrial settings, making it ideal for large-scale, high-load applications. 

Air Cooled Screw Chiller Systems 

An air cooled screw chiller is often selected when water availability is limited or when a simpler installation is preferred. These systems use ambient air to reject heat, eliminating the need for cooling towers and extensive water infrastructure. 

Air-cooled screw chillers are widely used in: 

• HVAC applications 
• Plastics and rubber processing 
• Food processing facilities 
• Sites with space or water constraints 

Refcon’s air cooled screw chillers are designed with robust construction, low noise operation, and adaptability to different load conditions, making them versatile for a wide range of industrial cooling needs. 

What Industries Rely Most on Ammonia Screw Chillers? 

Ammonia screw chillers are used in industries where large cooling capacity and precise temperature control are essential. These include: 

• Cold storage and cold chain facilities 
• Food processing and dairy plants 
• Beverage and brewery operations 
• Chemical and specialty chemical manufacturing 
• Pharmaceutical production 
• Large manufacturing and process industries 

In these sectors, cooling systems must operate reliably under heavy loads. Ammonia-based screw chillers are built to deliver stable performance, making them a trusted solution for mission-critical industrial environments. 

What to Look for in Ammonia Chiller Manufacturers for Large Projects 

Large ammonia refrigeration systems require specialised engineering and strict quality control. When selecting ammonia chiller manufacturers, buyers should look for partners who offer: 

• In-house engineering and system design 
• Experience with ammonia-based cooling systems 
• Single and twin screw compressor configurations 
• Advanced control systems and PLC automation 
• Factory testing and performance validation 
• Turnkey project execution and after-sales support 

A manufacturer with strong process control and quality standards helps ensure that the chiller delivers long-term reliability and consistent performance.
