Past

Ammonia has been in service as an established, pre-eminent industrial refrigerant for over 125 years. Ammonia is used in industrial refrigeration applications such as food production. CFCs, such as Freon, became popular in the 1930s due to their low toxicity. The chlorine in the refrigerant was found to have caused a hole in the ozone layer. Therefore, they have now been phased out. Non-chlorine, low toxicity, HFCs were developed to replace the CFCs

Present

HFC refrigerants have a high global warming potential, so they are being phased down to 21% by 2030

HFO refrigerants, such as, R1234ze when they leak, go through the weather system and end up in the sea. They have been reported to be harmful to marine life. These refrigerants are used for chilled water and process applications

Ammonia is in service as the best choice of refrigerant for industrial applications

Future

Between now and 2030 ammonia will become increasingly popular in non-industrial applications, such as, the cooling of data centres and the cooling of buildings. New ammonia chillers are simpler in design, therefore competitive in price to HFC chillers. The higher initial cost is paid back in electricity savings within 2 years- then they become cheaper. They use less electricity because ammonia has a latent heat bubble 5 times bigger than other refrigerants

Ammonia Alarm

In the event of a leak, the ammonia alarm is triggered and the chilling plant shuts down. The machine brings a fan on which disperses the ammonia into air. The ammonia refrigerant then absorbs into the moisture in the air

Leak Repair

For large leaks: breathing apparatus and chemical suits are required to isolate the leak and allow time for ammonia dispersal. For small leaks: an escape hood is required in the work location. Our engineers, trained in industrial refrigeration will repair the leak then start the machine back up

Industrial Refrigeration Maintenance of Pipework

Ammonia corrodes various metals and alloys. Steel, however, works well with ammonia. The use of steel makes industrial refrigeration maintenance different as opposed to HFC chillers

HFC

These chillers are prone to leaks on the copper pipework. On the condenser, the copper expands and contracts- eventually rubbing through against the steel frame. Vibration related leaks are also common

Ammonia

On an ammonia system, steel that is freezing then thawing on defrost or off cycles creates rapid rust formation and can lead to catastrophic failure of the pipework. Steel that is permanently frozen creates slower rust formation as the ice slows the oxidisation process. On a maintenance visit, our engineers carry out metallurgic testing to gauge the integrity of the steel
