There Is One Requirement That Is Particularly Important When Buying A Block Ice Machine

There is one requirement that is particularly important when buying a block ice machine

Large bar ice machine and large block ice machine, also known as large ice machine, are large machines used for mass production of ice cubes over 20 kg. At present, there are mainly two types of large block ice machines in China, one is the ammonia system ice machine, and the other is the fluorine system ice machine. The two systems are completely different due to the use of two different refrigerants, ammonia and fluorine. Therefore, companies that usually need to purchase large ice machines should pay special attention to their own situation and make choices during the inspection stage.

Here are five things to consider when choosing:

1: National policy

A large ice machine with an ammonia system has the following safety hazards: ammonia is toxic, flammable and explosive, and accidents occur in household ammonia systems from time to time; a small amount of ammonia leakage will cause storage and storage pollution, and a large amount of leakage will endanger personal safety. Therefore, it is not only inconvenient to use in refrigerated places, but also poses a threat to nearby residents. The government does not allow the use of ammonia systems in residential areas and densely populated areas. Therefore, before making your selection, you should check with your country's safety watchdog and see if it is possible to build a large ice machine with an ammonia system. Fluorine Systems' larger ice machines do not have this problem.

2: Security requirements

Larger ice machines in ammonia systems require stricter safety measures due to complex structures and a large number of pressure vessels.

Refrigerators and machine rooms should be equipped with sufficient water sources and ventilation facilities to deal with accidents. There should be special convenience cabinets for emergency rescue items in or near the computer room. It is equipped with oxygen breathing apparatus (or air breathing apparatus), protective clothing, alkaline filter, gas mask, rubber protective gloves, rubber water pipes and other protective equipment.

The machine room and machine room are equipped with necessary maintenance tools and are easily accessible, such as: pipe wrench, movable tools, pipe clamps of various specifications, rubber sheets, asbestos sheets, valves, fillers, iron wires, screwdrivers, wire cutters and others tool. Equipped with a variety of first aid remedies including: citric acid, boric acid and acid concentrate lemon juice, plum juice or vinegar. Rescue items and medicines should be checked regularly, and various safety equipment should be replaced in time, and must be checked before use.

Large ammonia block ice machine manufacturers must prepare a safety emergency plan. Any employee who becomes aware that an incident is about to occur or has occurred should immediately report the incident in accordance with the Incident Reporting Procedure. The person in charge of receiving should rush to the accident site immediately, and decide to start all or part of the plan according to the accident and development situation. Even if part of the plan is started, the rescue organization should be required to enter a state of preparation. And feel free to invest in the rescue.

3: Operating costs

In industrial refrigeration, ammonia systems have been used for over 70 years, and there have been no major technological advances over the years. Home automation cannot be fully automated due to the high cost of control valves and components and the high cost of automation. Moreover, due to the professionalism of the operation, the large ice machines of the ammonia system generally operate 24 hours a day, so a large number of professional and technical personnel are required to take turns to take care of them. Labor cost.

In addition, there are many refrigeration components in the large ice machine of the ammonia system, and the refrigeration system is more complicated. Routine maintenance and damage repair operations are complex and require significant labor costs as well as parts and material expenses.

4: Purchase fee

The ammonia system large block ice machine has the characteristics of large capacity and large cooling capacity. It is still widely used in large refrigeration systems. In many cases, design institute engineers are familiar with ammonia systems and are used to design refrigeration systems. Since the cooling capacity of a single ammonia machine can reach 250 kW or higher, while the maximum value of a fluorine machine (low temperature) is 100 kW, if you want to use a large cooling capacity, you must connect multiple machines in parallel. ), the ammonia machine is much cheaper than the fluorine parallel unit.

5: Technician

Ammonia system large block ice machines have great requirements on the professionalism of technicians, especially maintenance and repair personnel. Therefore, the training time of relevant technical personnel is long and the training intensity is high. In addition, the working environment has certain health hazards. Now fewer and fewer young people are willing to learn relevant skills, so it is more difficult to recruit personnel, and the requirements for salary and benefits are higher.

This is also a problem that many buyers do not easily think of in the early stage.
