Refrigerated Compressed Air Dryer
A refrigerated compressed air dryer is a device used to remove moisture from compressed air by lowering its temperature. It is a widely used type of air dryer in various industrial applications where the presence of moisture can lead to equipment damage, corrosion, and decreased efficiency.
How does a refrigerated air dryer work?
Refrigerant dryers are the most commonly used dryers in the industry and consist of an air-to-air heat exchanger and an air-to-refrigerant heat exchanger. The heat exchangers remove moisture from your compressed air by condensation of water within.This is essential to protect compressed air systems and every piece of equipment fed by compressed air from the harmful effects of moisture.
The most important criterion is to keep the relative humidity of compressed air below 50%.
Both air-cooled and water-cooled refrigerant dryers are available. Basically, the dryers cool down the warm wet air coming from the compressor, When the temperature of compressed air reduces, moisture condenses and is drained from the compressed air with the help of a high-efficiency water separator.
After that, compressed air is reheated to around room temperature so that condensation does not form on the outside of the pipe system. This heat exchange between ingoing and outgoing compressed air also reduces the temperature of the incoming compressed air, and as such reduces the required cooling capacity of the refrigerant circuit.
(1)terminal air dry filter--realizing refrigeration through a semiconductor cooler, it is a piece of equipment that provides purifying technologies for drying compressed air of a small flow 5scfm/min to 21scfm/min at the terminal where the air is used.
(2)high efficiency -- by way of freeze drying, it accomplish quite high dryness and high cost-effective ratio as well. This is a technology that satisfies the requirements in pneumatic operation in most cases and a technology that is most widely utilized.
(3) advanced utility model patent--the utility model patent cooler allows adequate cooling of air in a small volume and allows air-water separation to lower the humidity of the compressed air.
(4) high reliability and low cost--it needs no refrigerant and features low noise, long life and low cost of maintenance, as there is mo mechanical moving parts except the fan.
(5)compactness--ultra-small volume, easy installation and use, and simple operation.
Power:240w,working pressure:0.8mpa,air flow:5scfm,pressure dew point:less than 10 degree celsius.

Refrigerated Air Dryer
Refrigerated dryers use a cooling system to dry compressed air, thereby protecting downstream components from damage caused by traces of moisture in the air supply. Lowering the air temperature or dew point can cause excess moisture to condense. These dryers require a particulate filter or liquid separator to remove condensate from the air supply line. Refrigerated dryers require a power supply and are suitable for general purpose applications where the air is dried to a dew point sufficient to prevent condensation from freezing.
How does a refrigerated air dryer work?
Refrigerated dryers are the most common dryers used in industry and consist of an air-to-air heat exchanger and an air-to-refrigerant heat exchanger. The heat exchanger removes moisture from the compressed air by condensing the water inside. This is essential to protect the compressed air system and each piece of equipment supplied with compressed air from the harmful effects of moisture.
The most important criterion is to keep the relative humidity of the compressed air below 50%.
Air-cooled and water-cooled refrigerated dryers are available. Basically, the dryer cools the warm, moist air from the compressor, and as the temperature of the compressed air drops, moisture condenses and is removed from the compressed air with the help of a high-efficiency water separator.
Afterwards, the compressed air is reheated to near room temperature so that condensation does not form on the outside of the ductwork. This heat exchange between the incoming and outgoing compressed air also reduces the temperature of the incoming compressed air and therefore the cooling capacity required for the refrigerant circuit.
Energy efficiency of refrigerated compressed air dryers
Energy efficiency depends on the internal pressure drop and the electrical energy consumed by the dryer.
Keeping the pressure drop as low as possible
The internal pressure drop is the difference in pressure between the compressed air at the dryer inlet and outlet piping.
The lower the internal pressure drop of a refrigerated dryer, the lower the pressure you need to achieve with your air compressor. And the less energy the compressor consumes.
Our refrigerated dryers are designed to minimize the pressure drop and therefore consume the least amount of energy.
Polar-Chiller refrigerating compressed air dryers are the best after-disposing machine for the air compressors, and is the perfect clean machine in air-power controlling, air-power tools, precision machines, food packing, light industry, textile industry, chemical industry and so on.
The components of Polar-Chiller product are imported from famous factory in the world. Through perfect structure, specially designed pipeline system, high-efficiency heat exchanger/ cooling-evaporator and gas-liquid separator, can remove the moisture, oil drops and solid grain from the compressed air. They have an advantage that others do not have. If you choose it, you will get the greatest worth.
Features and Benefits
â?¢ The build-in aftercooler for high temp type is suitable to operate at different temperature below 80â??
â?¢ The unit applies refrigerant pressure control mode, which makes the air dew point identically equal.
â?¢ The selected and used parts and components are the products from famous manufacturers in the world, which can ensure operational reliability of the unit.
â?¢ Cooling evaporator adopts the structure of large heat-exchange area and detour spiral. That makes the compressed air stay long inside the evaporator to ensure sufficient heat exchange. More moisture in the air can be condensed to become liquid drop, and therefore optimum drying effects can be achieved.
â?¢ The re-heating device makes heat exchange between the cold air and the refrigerant high-pressure pipe, which can exclude the condensation dew of downstream pipe. This ensures the reliability of the hydraulic system. On the other hand, the cold-media in high-pressure pipe flows into the condenser only after it has been cooled. That can reduce the load of the condenser and increase COP (Coefficient of performance), and therefore the dryer can work normally even in harsh conditions.
â?¢ The design of inside piping system takes various principles of compress air purification into full consideration in order to separate the moisture and most remain solid grains and oil-drops, which have been pre-treated when passing the main pipe, from the compressed air by means of gravity separation, impacting, high-speed centrifugalizing, baffle-separation and diffusion, It ensures the desiccation and cleanliness of output air, and reduces the load of air treating element in downstream to minimum.
