Compressor drier is one of the auxiliary devices of compressors, which is generally responsible for drying the air and removing moisture. Depending on the type of industry, the degree of importance of this task is different, and for this reason, different types of compressor dryers have been produced.
What are the tasks of an industrial moisture or humidifier?
Air dryer is a very necessary device in compressed air systems such as compressors. Moisture and condensation are two unwanted by-products in all air condensation systems. Water in these systems can condense and collect and damage compressor units as well as downstream process equipment. In these cases, a refrigeration dryer or any type of dryer comes into play. In general, the duties of a dryer compressor are:
Removing blue contamination
In industries that use high-purity compressed air, such as laser cutting and welding, plasma production, microelectronic parts production, food and pharmaceutical products production industries, painting, plating and shot blasting, water pollution is a problem. It is very big. In these industries, compressed and dry air is usually used for cooling parts and equipment or devices such as lasers. If there is water pollution, the overall efficiency of the system will decrease, a lot of energy will be wasted and it will damage the system. Therefore, in these industries, the duty of industrial dryers and dehumidifiers is to remove water pollution so that dry and moisture-free air leaves the device.
Prevent water from forming
Compressed air is usually saturated with water. Decreasing water temperature or excessive compression and pressurizing it can cause precipitation of released water vapor. When the compressed air enters the downstream equipment of the compressors in this state, there is a risk of water accumulation in small holes or pitting the parts. This is very dangerous and damaging for devices that have high sensitivity, such as special measuring and monitoring devices. Therefore, the dryer compressor has the duty to prevent water accumulation by drying and removing water.
Prevent corrosion of parts
The presence of water in the internal parts of the equipment causes corrosion on their steel surface. There is a possibility of water accumulation in pipes, tanks, inner surface of mixing equipment, etc. through saturated and condensed air. The same event can cause corrosion in the internal surfaces of this equipment, which in turn will damage a product or process. Therefore, dryers have the duty to prevent this by removing water and moisture.
Prevent frostbite
Water that has accumulated in air compressor systems can freeze. An industrial dehumidifier with frozen water creates many problems. As the presence of frozen water can prevent the movement of pneumatic actuation components of valves and measurement systems. Therefore, in turn, it will disrupt the operation of the device. Therefore, the dryer compressor has the duty to prevent freezing by removing water from the compressed air, which in turn prevents future losses.
Improve the performance of pneumatic or electric devices
All electrical devices and equipment that use compressed air energy to run air motors or turbines require a compressor dryer. For example, pneumatic grinding machines, electric drills and hammers, and various compressors are of this category. In this case, water is deposited in the internal parts of these devices, which in turn prevents the proper transmission of power from the side of the air engine. Therefore, the dryer compressor increases the efficiency of pneumatic and electric devices by removing this amount of air humidity.
Prevent microbial growth
Compressed air is used in the food and beverage industry to mix ingredients and transport them. In these industries, hygiene and uncontaminated compressed air is very important because any type of microbial contamination will lead to food contamination and spoilage. Pharmaceutical production industries also have much more strict health regulations. In these cases, they use a dryer compressor to remove water and condensate and the growth of microbial agents, which is one of the most important tasks of these devices.
