China industrial air dryer suppliers compressed air dryer 7.5HP-100HP refrigerated air dryer

The amount of water vapor in the air compression by compressed air temperature determined: in case of compressed air pressure is basically the same, reduce the temperature of the air compressed compression to reduce the amount of water vapor in the air, and the excess water vapor will condense into liquid. Freezing dryer is according to the corresponding relationship between the saturation water vapor pressure and temperature, use refrigeration device makes the compressed air is cooled to a certain dew point temperature, precipitation containing water, through the steam water separator and electric drainage device will discharge water, so that the compressed air can be dry.

Working Principle

The refrigerated dryer adopts the working principle of cooling and condensation, and is mainly composed of three parts: heat exchange system, refrigeration system and electrical control system. The compressed air first enters the pre-cooler for air-air or air-water heat exchange, and then enters the cold and hot air exchanger to exchange heat with the cooled cold air that has come out of the evaporator to further reduce the temperature of the compressed air. After that, the compressed air enters the evaporator and exchanges heat with the refrigerant. The temperature of the compressed air drops to 0-8°C. The moisture in the air is precipitated at this temperature, separated by the gas-water separator, and then discharged through the automatic drain. The dry low-temperature air enters the hot and cold air exchanger for exchange, and is output after the temperature rises.

Features

For refrigeration and air systems, more than 20% margin is reserved for design parameters.

Refrigeration compressor adopts advanced rotary or scroll type, piston type hermetic refrigeration compressor and semi-hermetic screw refrigeration compressor (above 20HP). Features stable operating temperature, low noise, reliable performance, power saving, long life, and a high energy efficiency ratio. The degree of protection is IP54 (dustproof and splashproof).

The air condenser of the heat exchanger is made of high-quality copper tube with aluminum fins, and the spoiler structure has high heat transfer efficiency, small size and compact structure. The cylinder material is made of stainless steel or carbon steel galvanized to avoid secondary pollution of compressed air.

The equipment structure design is reasonable, easy to maintain, the surface is thermally sprayed, the appearance is beautiful, no rust, no foundation installation required. It ensures stable operation, low maintenance rate, no consumables, low operating costs, and no need for special personnel to wait.

Frequently Asked Questions

1. What is the working principle of this refrigerated dryer?

The dryer operates on a cooling and condensation principle. It lowers the temperature of the incoming compressed air to 0-8°C, which precipitates moisture. The water is then separated by a gas-water separator and discharged via an automatic drain before the dried air is warmed and output.

2. What type of compressor is utilized in the system?

The system utilizes advanced rotary, scroll, piston-type hermetic, or semi-hermetic screw compressors (for models above 20HP). These compressors are selected for their reliable performance, low noise, and power-saving operations.

3. What is the protection rating of the compressor?

The refrigeration compressor features a protection level of IP54, providing robust protection against dust and splashes for long-term operational reliability.

4. How is secondary pollution of the compressed air prevented?

The cylinder material of the heat exchanger is constructed from stainless steel or galvanized carbon steel, preventing rust and secondary contamination of the dry compressed air.

5. What are the electrical power requirements for these models?

Models up to and including OSGA-12NF require a 220V 50Hz 1P power supply. All other larger models require a 380V 50Hz 3P power supply.

6. Is special foundation or installation required?

No, the equipment is designed for stable operation without the need for a dedicated foundation. Its structure allows for easy maintenance, low operating costs, and does not require dedicated operators.
