The AC system will definitely require flushing if it is depressurized. For example, a broken capacitor was dismantled, the system was not used in winter, the fact that the capacitor is broken was forgotten, and in summer the car owner turns to the workshop to repair and refill the air conditioner. A regrettable surprise for him will the fact that installation of a new part will not be enough for its restoration. The whole problem is that the moisture is already in the system and corrosion of aluminum parts has already occurred. Therefore, if failure occurs, flushing of the whole system is essential.
When the compressor breaks down, flushing is highly essential before installing a new one. If you skip this operation, the new compressor will soon become unusable. Therefore, when you hear a noise or any other sounds from the compressor, you can not postpone visiting a car service. Visit a service center immediately and save your own time and money.
Frequency of air conditioner flushing
It is important to keep the AC system clean. Even the smallest particles of dirt and dust will lead to trouble and a significant deterioration in performance. If you do not wash the system on time, the warranty for all its elements will be eliminated.
Breakdowns often occur because of the contaminants in the system. After carrying out repair and washing, the functions of the entire system will be restored in full. The supply of the refrigerant and oil will normalize.
Equipment for air conditioning system flushing
It is impossible to conduct air conditioner cleaning without quality equipment. MSG Equipment manufactures and sells equipment for cleaning the pipelines of the air conditioning system.
MS101P is a pneumatic flushing stand. Washing is carried out by means of fluid flow that circulates through a closed circuit. Thanks to general-purpose fasteners, the stand is connected to the car of any brand and date of issue. The equipment has small dimensions, so it is mobile and convenient to use. We also offer a ready business solution, the AC system flush kit.
How to understand that the system requires flushing?
Flushing is required when:
- Moisture is observed
- The refrigerant circuits are open for a long time
- Dust, dirt on the contour lines of the system is present
- There are doubts about the quality of the lubricant and additive
Contamination example
Contamination can be observed after visual inspection. It can be a dark oil, presence of foreign particles, metal sawdust, corrosion. Any foreign bodies and their particles are evidence of contamination.
The dark color of the grease signalize of a failure of the compressor piston rings. Their early wear cause oil darkening.
Aluminum corrosion appears on the surface in the form of a white powder. The system is constantly under the influence of humidity. Moisture mixing with the refrigerant forms an acid which corrodes parts of aluminum.
The consequence of contamination are rubber particles. When low-quality solvents and additives are used, the O-rings break apart.
Which fluids are used to flush the system
Forbidden fluids that can not be used during AC flush: cleaning agents for brakes, degreasers, carburettor cleaners. These fluids leave chemical particles in the system, which cause serious problems. Do not use explosive and toxic materials for flushing.
You should find out which air conditioner cleaning liquid will be used for flushing in the car workshop. Trying to reduce the cost, careless specialists use for washing organic solvents, which is wrong.
Flushing equipment must have good dissolving properties, must combine with the AC elements of metal, plastic, rubber because the fluid is in contact with gaskets and seals during washing. A quality cleaner evaporates quickly leaving no chemical fragments on the washed parts.
Select a workshop where flushing is conducted carefully. There should be special equipment for carrying out these works in a service center.
