Working principle
The amount of water vapor in compressed air is determined by the temperature of the compressed air: while keeping the compressed air pressure basically unchanged, reducing the temperature of the compressed air can reduce the water vapor content in the compressed air, and excess water vapor will condense into liquid. A freeze dryer is a device that uses a refrigeration device to cool compressed air to a certain dew point temperature based on the correspondence between the saturated vapor pressure and temperature of water. The water contained in the air is precipitated and discharged through a steam water separator and an electric drain, thereby drying the compressed air.

Working Principle
Heat of Compression Desiccant Air Dryer make full set of the heat generated by the compressor in the compressed gas to regenerate the adsorbent. For ordinary suction dryers, this part of high-temperature heat source needs to be cooled down before use, so this part of heat is wasted in vain,and the compression heat series dryer makes full use of this part of heat to regenerate adsorbent, which is not only economical the electric heater power consumption required by the micro heat drying machine series is reduced, and the gas consumption at this stage is eliminated. Therefore, this product is a good energy-saving product.
Product Characteristics
- High efficiency and energy saving;
- The pressure dew point can reach-0 C°--40 C;
- Equipped with imported brand PLC controller to realize interlocking function;
- High quality switching valve,stable and reliable, can ensure the integrity of the working process and prolong the working life of component;
- Special adsorbent with high hygroscopicity is selected with uniform shape and size, high strength,low dew point. Less dust and long service life;
- The unique airflow distribution design ensures that the airflow distribution is uniform when the high temperature air is heated & regenerated ,and also the low temperature air is adsorbed, so that the adsorbent at the edge of the desiccant tower can be fully utilized and the tunnel flow effect can be avoided;
- Low pressure loss;
- Three types of drainage function: liquid level, time and manual operation;
