How does an ammonia chiller work?

An ammonia chiller is a type of refrigeration system that uses ammonia as the refrigerant to remove heat from a space or process. The basic principle of operation is based on the thermodynamic cycle known as the “vapor compression cycle.” This cycle is composed of four main components: a compressor, a condenser, an expansion valve, and an evaporator.

Why is ammonia used in chillers?

Ammonia is used in chillers for several reasons, including its excellent thermodynamic properties, high cooling capacity, and environmental benefits. Ammonia has a high cooling capacity, which means it can remove a large amount of heat from a space or process with minimal refrigerant flow. This makes it an efficient and cost-effective choice for large-scale cooling needs, such as in industrial or commercial settings. It is also an environmentally friendly refrigerant that does not contribute to ozone depletion or global warming. It is a natural substance that can be easily recycled or disposed of, and it has a lower impact on the environment compared to synthetic refrigerants, such as chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs).

Ammonia Chillers

For a complete packaged system where deep freezing is necessary, our air-cooled Ammonia Chiller range, i-Chiller Process LTn, is specifically designed for processes from -12°C down to -30°C.

With a simple plug and play installation, the i-Chiller Process LTn can be ready to use in no time at all. The unit is for outdoor installation, and the ultra compact weatherproof galvanised steel body keeps the unit nicely contained and easy to position in most environments.

The i-Chiller Process LTn delivers unrivalled reliability and safety, utilising the latest state of the art freezing technologies. The dual circuit, inverter driven semi-hermetic screw compressor allows for low-charge ammonia refrigeration, without sacrificing freezing capacity or energy efficiency.

Whether it's for frozen produce such as ready meals, meat, fish, fruit and vegetables, or pharmaceutical storage application, these highly efficient ammonia chillers will help contribute towards your ESG targets through lowering your energy consumption and by using the natural, zero Global Warming Potential (GWP) refrigerant (R717).

We will design, install, commission and project manage bespoke turnkey solutions and provide full, tailored 24/7 maintenance & breakdown support with our fully qualified maintenance engineers.

Ammonia Chiller Benefits

Complete packaged system

Compared to most Ammonia Chillers, all ICS Cool Energy units are compact and contained within a galvanised steel body which offers exceptional flexibility for ease of installation, operation and maintenance.

As a means to maintain temperature with precise control, you can pair the i-Chiller Process LTn with ICS Cool Energy Cold Storage Hire units to provide the most flexible way to store and keep your frozen produce.

Energy efficient & sustainable

R717 refrigerant grade Ammonia is one of the most efficient refrigerants available and perfect for organisations wanting to improve their sustainability footprint. Being a natural refrigerant, the climate friendly R717 has a zero rating for ozone depletion and global warming potential. These chillers also consume no water as part of the process.

I-Chiller Process LTn features Variable Speed Drives (VSD) installed as standard, which vary the output depending on the demands put on the system and further improve the efficiency of your process. The chillers also consume no water as part of the process.

Safety & monitoring

i-Chiller Process LTn units are equipped with a range of safety features, including pressure sensors, temperature sensors, and automatic shut-off valves, ensuring safe and reliable operation.

With a digital control panel and web interface, the unit collects performance data that can be monitored externally on any browser or mobile device.
