What are the causes of corrosion in industrial chillers?

With the development of technology, industrial chillers are increasingly being applied in various fields of industry, making their due contributions to industrial production and improving product quality
And industrial chillers are also mechanical equipment, and after running for a long time, some problems may occur, among which corrosion is one of the common phenomena of chillers.
In order to prevent corrosion and extend the service life of the chiller, the following analyzes several causes of chiller corrosion, and then takes corresponding measures to avoid chiller corrosion.

1. Unreasonable engineering construction and design installation cause corrosion.
Some industry friends may have encountered situations where, after purchasing industrial chillers, especially ordinary chillers, they have not undergone anti-corrosion or rust prevention processes and are directly placed in outdoor environments. Over time, exposure to wind and sun can cause shell corrosion.

2. Corrosion caused by incorrect installation or abnormal operation of the water processor.
The cooling water pipeline is the channel through which the water-cooled chiller circulates cooling water. The water quality determines whether the system pipeline has scale and rust. If the water processor is not installed properly or works abnormally, it can cause rust to occur.

3. The dirt remover is mostly a Y-shaped filter, which is weak in filtering small impurities.
The Y-shaped filter is easy to install and clean, and can perform coarse filtration on mechanical impurities, iron filings, and sand particles. However, it cannot achieve fine filtration on small impurities. Therefore, if the unit runs for a long time, it is easy to cause scaling, mud accumulation, and other impurities in the condenser.

4. There is no quick drain valve installed in the chilled water system
Quick discharge valve is a discharge valve used in refrigeration machines or chilled water systems. It has the characteristics of simple structure, good sealing, small volume, light weight, and is particularly suitable for regular discharge of systems. At the same time, it has advantages such as corrosion resistance, impact resistance, and long service life.
At present, many enterprises do not install quick discharge valves at the end plates of industrial refrigerators. It will cause corrosion of the system pipelines. When using a chiller, the drain valve should be opened and closed three times a week to facilitate system drainage.

5. The cooling system water supply pipeline is not equipped with a water meter
The cooling system generally uses chemicals and microbial agents to treat water quality, which are used to kill and manage internal fungi, microorganisms, various types of dirt, etc. When using chemicals, a certain amount of chemicals should be prepared according to the amount of water replenished and the system water volume.
If there is no water meter for measurement, it will cause inaccurate dosing and lead to corrosion of the system pipeline in the later stage.

6. Corrosion of equipment surfaces caused by acidic and alkaline gases in the environment
In factory production, it is inevitable that there will be special gases, such as the flow of acidic and alkaline gases, which can cause harm to the surface of the equipment. Therefore, when choosing a chiller in such an environment, it is necessary to explain to professionals in advance and prioritize the use of explosion-proof and corrosion-resistant pipes in the electrical control case or evaporator pipeline. To avoid causing corrosion and loss in the later stage.
