Why you need to flush the car air conditioning system
The air conditioning system will need mandatory flushing if it has been depressurised. For example, a broken condenser was dismantled. During the winter period the air conditioner was not used, the breakdown was forgotten about, and in summer the owner of the car goes to a workshop to repair and refill the air conditioner. Here the unfortunate surprise for him will be that for restoration, installation of a new part will be not enough. The whole problem is that moisture is already in the system and corrosion of aluminium parts has occurred. Therefore, if a breakdown occurs, flushing the entire system is a must.
When a compressor breaks down, flushing is mandatory before installing a new compressor. If this operation is skipped, the new compressor will soon fall into disrepair. So, when you hear a hum or any other compressor sounds, you should not postpone a trip to the service station. Get the service done on time and save yourself time and money.
Regularity of air conditioning system flushing
It is important to keep your climate system clean. Even the smallest particles of dirt and dust will cause trouble and a significant deterioration in performance. Failure to flush the system in time will invalidate the warranty on all parts of the system.
Breakdowns are often caused by contaminants throughout the system. After repair work and flushing, the function of the entire system will be restored to its full potential. Refrigerant and oil flow will be normalised.
Breakdowns are often caused by contaminants that are present throughout the system.
Equipment for flushing the car air conditioning
It is impossible to flush the car air conditioner without quality equipment. MSG equipment manufactures and sells equipment for cleaning pipelines of car air conditioning systems.
MSGMS101P – is a pneumatic flushing station. Flushing is carried out by means of a fluid flow that circulates through a closed circuit. Thanks to universal fasteners, the station can be connected to machines of any make and date of manufacture. The station has small dimensions, so it is mobile and easy to use.
How to determine if the system needs flushing
Flushing will be required if:
- Dust, dirt has been noticed on the system circuit lines;
- Refrigerant circuits have been open for an extended period of time;
- There are traces of moisture present;
- There are doubts about the quality of the lubricant and additive.
Example of contamination
Detect contaminants after visual inspection. They appear as dark oil, foreign particles, metal filings, corrosion. Any foreign bodies and their particles are evidence of contamination.
Dark coloured grease indicates that the piston rings on the compressor are broken. Early wear of the piston rings causes the oil to darken.
A dark colour of the lubricant is an indication of contamination.
Aluminium corrosion appears as a white powder on the surface. The system is constantly exposed to moisture. Moisture mixing with the refrigerant forms an acid that corrodes the aluminium parts.
Acidic corrosion of aluminium corrodes the surface as a white powder.
Rubber particles are a consequence of contamination. When poor quality solvents and additives are used, O-rings fall apart.
Which fluids are used to flush the system
The prohibited fluids that cannot be used for flushing are: brake cleaners, degreasers, carburettor cleaners. These fluids leave chemical particles in the system that cause serious problems. Do not use explosive or toxic materials for flushing.
A car shop needs to know what fluid will be used for flushing. In an effort to reduce cost, careless craftsmen use organic solvents for flushing, which should never be done.
Cleaning equipment must have a good solvent capacity, to be combined with elements of the conditioner from metal, plastic, rubber, because during washing the liquid comes into contact with seals, oil seals. A quality cleaner quickly evaporates without leaving chemical fragments on the parts being washed.
Select a car service or workshop that offers the service of washing the system of car air conditioners should be carefully. The car service must have special equipment to carry out this work.
