Filter Drier Solution
A refrigerant filter drier mainly contains a molecular sieve, activated carbon, and activated alumina.
Activated alumina is mostly just used to get rid of those molecules or particles that could form acidic substances. This is inclusive of hydrochloric and hydrofluoric acids.
These are the results of water and refrigerant being broken down at scalding hot temperatures.
Molecular sieve- The main function is to remove moisture and solid particles.
Activated alumina- The purpose is usually to clean up acid after a burnout.
A filter dryer can absorb molecules selectively depending on their size or polarity.
The device allows the absorption of water but lets larger and more functional molecules like oil pass through usually.
This happens because the surface of a filter dryer is coated with a positive charge.
These charges attract polarized molecules that can produce acids like water.
As a result, a liquid line filter drier can help when situations like freeze-ups or system corrosion arise while keeping the formation of acids to a minimum.
Filtration process, a filter dryer can do this with the assistance of a screen, wire mesh, and desiccant core, all of which you will be easily able to see inside the system.
A burnout filter drier is a solid core filter drier, the solid core is made of 70% alumina and 30% Molecular sieve.
It can efficiently absorb the harmful substances caused by the burning of the compressor motor and then protect the whole refrigeration system to avoid damage.
There are two extra ports beside the inlet and outlet, they are used for connecting the pressure gauges that can measure the pressure difference between the two sides of the filter drier.
Burnout Filter Drier Advantages
It has similar features to other filter driers, like corrosion-resistance paint for cover, strong body, high efficiency for absorption, good acid removal ability, and can be used for all the refrigerants, and all the environments.
Burnout Filter Drier Installation Location
There is no limit for the installation position, but in our experience, for better function, it’s better to install the burnout filter drier on the inlet of the compressor, in front of it, it’s better to use a vibration absorber.
A suction-line filter drier is used on the suction pipe of the refrigeration or air conditioning system to absorb water, acid, and solid pollutants.
The big features of the suction line filter drier are: It has two maintenance ports to easily measure the pressure drop in the refrigeration system.
The filtration accuracy reaches 35 microns, suitable for all refrigerants.
At the beginning of system installation, because of the presence of welding slag and particles inside the pipeline, it is necessary to install a replaceable core filter drier in the liquid line or suction line.
A replaceable core filter drier is used for liquid and gas lines in refrigeration, Cooling, and AC system, it can effectively remove the pollutants caused by the burning of the compressor motor.
They have good protection and cleaning functions for compressors in a refrigeration system and also have a function for absorbing moisture and removing acid in a special system.
The solid core can be changed, you can have a new filter drier shell by changing the core, very cost-effective.
For different functions, you can choose a solid core or stainless steel core for a replaceable filter drier.
If you don’t know how to choose, just contact us for suggestions from our engineers.
Notes: Try to install the filter drier shell to the upstream of liquid pipe controlled, to make sure it can provide the best protection. You can install the sight glass to inspect the drying function.
When you install the filter drier shell, make sure the connector is up or on the horizontal position, to avoid any pollutant entering the system when replacing the filter core.
Leave enough space for changing the filer core when you first install the filter drier shell.
Before understanding this question, you need to understand what is refrigeration system.
If there is moisture in the refrigeration system, it will bring a series of bad effects on the operation and running of the system.
Because the Refrigerant is insoluble in water, and the refrigerant that contains water passes through the expansion valve, the water will be frozen because of the reduction of pressure and temperature, and this freeze will block the system to affect the normal fluid supply.
At the same time, if the refrigerant contains water, it will accelerate the corrosion of the metal parts of the refrigeration system.
So the liquid line has to install the filter drier to absorb the moisture.
The second use is the provision of physical filtration, which is especially required in cooling appliances.
If the refrigerant is mixed with impurities such as dust, and iron filings, during its circulation process, it will be easy to block the expansion valve to affect the flow rate of the whole refrigeration system.
Therefore, it’s very necessary to install a filter drier in front of the expansion valve and behind of liquid receiver to filter the moisture and impurities and make sure good running for the refrigeration system.
In the following, you can also learn filter drier everything you need to know, and find the right liquid line filter drier for your system here.
filter driers are also used in air conditioners.
The difference is that air conditioner filter driers are small and have low flow rates.
Refrigeration filter driers are large and have high flow rates.
Like others, there are two kinds of filter driers in an AC system（VRF）.
Suction filter driers come in handy to protect parts of the system in case of any failure, whereas liquid line filter driers are needed to help in filtering liquid refrigerant.
The filter drier should be replaced every two years.
However, judgment also needs to be made based on how wet or dry the sight glass is.
If the sight glass shows wetness, then you need to replace the filter drier in time.
You also need to replace the filter drier if the refrigeration system compressor burns out, has a high-pressure drop, or if you replace the refrigerant.
Beside that, they are also includes unusual noises, leakage of a strange residue, bad odor is emitted from your system, cooling is not as effective as it once was, and the sight glass is cloudy.
If you experience any of these that were not there when you used your system in the past, it probably means that your filter drier has gone bad, and it’s time to grab a new one.
Yes, of course.
If your refrigeration system has been installed and is running well, you do not need to install a suction line filter.
If your refrigeration system has experienced compressor burnout or has many welding points, we recommend that you install a suction line filter.
Because it can effectively prevent the compressor from burning out.
In addition, you also need to consider the project budget. If the budget is sufficient, it is recommended to install a suction line filter.
If you need to change a new compressor, please check Copeland, Bitzer, Frascold, Carrier, etc.
A suction-line filter drier is meant for protection.
They should be installed as close as possible to the compressor so that this expensive item can always be protected from harm.
If you decide to install a suction vibration eliminator, you should make sure that the filter drier is above it.
That being said, they can be installed both horizontally or vertically as long as they are between the right parts.
The matter of whether a filter drier should be installed inside or outside has remained debatable for a long time.
The answer for all cooling systems mostly depends on where the indoor coil has been placed.
The best choice of deciding whether the filter-drier should be placed inside or outside must be dependent on the placement of this coil.
The closer the filter is to the indoor coil, the less likely it is for the metering device to be flooded with residue.
However, the standard practice is to install filter dryers directly in front of the expansion device.
This standard practice means that one will be placed in the indoor section in some systems while the other will be placed outside.
Many people prefer keeping both driers outside because this makes them easier to service.
It can be said that there are multiple methods of placement, and as long as they adhere to the rules as mentioned earlier, there is a low chance of any issues.
It mostly comes down to preference and design.
