Maintenance of an industrial ammonia refrigeration system

Information and advice for correct maintenance of your system

In today’s article, we would like to talk to you about the importance of correct and constant maintenance of industrial refrigeration systems and the crucial importance of these in maintaining high levels of efficiency in your systems.

Zudek, for more than thirty years, has used exclusively natural refrigerants for its machines, in particular ammonia (NH3) which of all refrigerants is the one with the lowest environmental impact and the highest energy efficiency.

However, the management and maintenance of a system that uses natural refrigerants requires particular attention and skills to guarantee the safety, efficiency and durability of the system itself. Although ammonia is by far the most efficient refrigerant fluid, ammonia is also known for its toxicity and flammability, which requires careful management and rigorous maintenance by highly qualified personnel.

Maintenance, in refrigeration systems in general and even more so in ammonia systems, is essential to ensure that the system operates safely and efficiently. Regular maintenance can help prevent unexpected breakdowns, reduce operating costs and extend the life of the system.

The importance of maintenance planning

For this reason, it is important to organize correct maintenance planning with professionals who are able to manage and organize ordinary and non-ordinary interventions.

The first step is to schedule periodic inspections and constant checks of the machine to identify any anomalies or any type of malfunction. To constantly monitor the machines remotely, Zudek uses the Telematik system, our telemetry service that allows you to monitor the operation of the machine remotely. In this way our technicians are able to continuously detect the machine parameters and the customer does not have to worry about it.

It is then essential to be able to identify possible leaks within the system. Zudek machines are all equipped with a sensor that allows you to identify leaks even if they are minimal.

Safety and cleanliness of the system

For greater safety of the system and to avoid any possible leak, refrigeration systems can be integrated with abatement systems, capable of decreasing the concentration of gas in the event of leaks.

All Zudek machines, equipped with cabinets, can be integrated with our Safematik ammonia reduction system.

The abatement system is able to detect ammonia leaks and neutralize them if necessary. Safematik is made up of a scrubber, a fan and a detection system and allows you to neutralize ammonia in the event of a leak. The system breaks down the refrigerant in tanks of water or other acidic solutions.

Finally, it is very important to always be able to monitor the cleanliness of all the components of the system, the replacement, when necessary, of the filters and the lubrication of all the moving parts, in order to avoid wear and improve efficiency.

Staff training

Correct staff training is essential to ensure the safe and correct management of the system. It is necessary for technicians to be thoroughly educated and trained on products and systems.

Our team is highly specialized in interventions on systems that use natural refrigerants and our company fleet is made up of vans equipped with the necessary equipment for each type of intervention. We are equipped and trained to carry out rapid interventions all over the world because timeliness is a fundamental requirement in this type of sector.


Ammonia is an effective refrigerant but requires rigorous management and maintenance to ensure the safety and efficiency of the industrial refrigeration system. Regular maintenance planning, staff training and attention to safety are critical factors for the long-term success of an ammonia refrigeration system. Ultimately, investing in maintaining high standards will lead to optimal plant operation, reducing risks and maximizing benefits.
