Performance that Reflects

Our Commitment to You

Moisture stands out as the predominant contaminant posing a threat to your compressed air system. This underscores the crucial role that dryers play in any air treatment process. If you're questioning the significance, thinking it's just water, it's essential to delve further as presence of water can seriously wreak havoc on your compressed air system, downstream equipment, and, most importantly, on the final products.

Why Industry Needs Air Dryer?

The requirements of modern industry for compressed air can be divided into the following aspects:
1. Pressure and flow requirements;
2. Requirements for dryness (i.e. water content or dew point temperature);
3. Cleanliness requirements (relatively complex, including: solids, oil mist, microorganisms, harmful gases, etc.)
The filter plays a key role in the compressed air drying and purification system. The use of different filters can remove oil (including liquid, gas), solid impurities, microorganisms, harmful gases and other pollutants in the compressed air. In the compressed air drying and purification system, filters exist everywhere. In industrial production, the filter used by the compressed air system is often divided into several categories according to its use: oil removal filter, dust removal filter, sterilization filter and special filter
The requirement of dryness is to remove the moisture in the compressed air, and it needs to be dired by a compressed air dryer. According to the drying principle, it is divided into a refrigeration dryer, an adsorption dryer, or a combination of refrigerated and adsorption dryer.
Compressed air is an important power source widely used in industrial fields, and is the second largest power source after electricity. Compressed air comes from the atmosphere, which contains a lot of dust, water vapor, impurities and so on. Unpurified compressed air will seriously wear pneumatic equipment, and cause blockage and corrosion of valves, pipelines, etc. It causes damage to production equipment and scrap of products, affecting normal production. Therefore, it is necessary to purify the compressed air it is essential. With many years of professional experience, Epsea not only focus on the research and development and equipment manufacturing in the field of compressed air purification, but also through our understanding and summary of the manufacturing industry, we can provide users in various industries with more economical and
efficient comprehensive compressed air purification solutions.

Smart Dry Product Overview

The ARIES PRO Smart Dry series features a tube-type exchanger dryer design, incorporating interlocks of premium style and quality. Specifically crafted for the Indian market, it caters to those who prefer cost-effective solutions while building a fleet of dryers.

Working Principle

The amount of water vapor in the compressed air is determined by the water content of the compressed air. Under the condition of keeping the compressed air pressure basically unchanged, when the temperature drops, the water holding capacity of the air also decreases, and the water that was originally gaseous will become liquid. The refrigerated dryer is based on this principle of dehumidification, using a refrigeration device to cool the compressed air to a certain dew point temperature, so that the gaseous water is condensed into a liquid state. Then through the separator, the gas and liquid are separated and the water is discharged from the automatic drain, so that the compressed air is dried. The refrigeration and heat dissipation device of the air-cooled refrigeration dryer is an air-cooled radiator. The high-pressure part of the refrigeration system is cooled by a fan and taken away with the air volume blown by the fan.

Smart Dry Plus Product Overview

A very special product ARIES PRO Smart Dry Plus comes with Aluminium plate type heat exchanger, so there is no corrosion! The exchanger efficiency is higher than other designs and hence shows a better performance, even when it comes to handling higher temperatures. The product comes with standard user-friendly smart LED controller.

Working Principle

The amount of water vapor in compressed air is determined by the water content of the compressed air. Under the premise of keeping the pressure of compressed air basically unchanged, reducing the temperature of compressed air can reduce the content of water vapor in compressed air, and the excess water vapor will precipitate into liquid droplets. According to the water saturation and the relationship between steam pressure and temperature, the refrigerant dryer is used to cool the compressed air to a certain temperature, precipitate the contained water condensed into droplets, separated and collected by the gas-water separator, the drainer will discharge the water, so as to dry the compressed air.

Smart Dry Magnum Product Overview

Working Principle

ARIESPRO series, high pressure dryer series i.e. SMART DRY MAGNUM is one of it’s kind. The moisture content in compressed air is determined by the amount of water present in it. By maintaining the pressure of compressed air while decreasing its temperature, the moisture content in the air can be reduced. Excess moisture condenses into liquid droplets, a process utilized by refrigerated dryers. These dryers employ refrigeration systems to cool the compressed air to a specific temperature, causing water vapor to precipitate and collect as droplets. The separated water is then drained out, effectively drying the compressed air. Further drying is achieved by passing the air through an oil-water separator and a C-class water separator. Prior to this, the air undergoes preliminary filtration through the oil-water separator and filter, followed by precision filtration of T and A-class filters. This process ensures a cleaner, oil-free, and dry air source.

Extreme Speed

Pre-cooling System The unique structural design of the precooling channel ensures that the compressed air at the entrance is fully and quickly cooled. Ultra-low pressure loss makes the refrigeration system cycle run more efficiently

High Efficiency

Evaporation System The improved evaporation channel is developed so that the heat of the compressed air is fully absorbed by the liquid refrigerant. Absorbed, the refrigerant is completely "vaporized" back to the compressor suction port for the refrigeration system. In a cycle, the gaseous water in the compressed air is cooled and a large amount of liquid water is precipitated

Dual Stage

Water Separator System Efficient gas-water separation contains crude. The two-channel structure is compressed into the water distributor. The air flow rate is reduced, the coarse water separation structure will completely separate a large number of liquid water, and the fine water separation. The structure will again separate some of the liquid water droplets carried by the airflow fluid drag force, ensuring that. Maximum separation efficiency, thus achieving a more stable dew point

R410a refrigerant is used, which is more efficient than R22 and does not damage the ozone layer
The smart energy hot gas bypass control system can maximize the cooling capacity of the combination, and accurately control the excess cooling capacity at the same time, that is, to ensure the dew point and not to block the ice.
