Micro-heat Adsorption Dryer-ZHD Series | Compressed Air Purification

The micro-heat adsorption dryer (micro-heat dryer) is a product developed based on the advantages of heat regeneration and no-heat regeneration. It utilizes the drying agent's adsorption capacity for water and uses the temperature & pressure swing adsorption principle to dry the compressed air. Regenerated gas carries out the regeneration for the drying agent after the temperature is increased, which may improve the regeneration effect, and reduce gas consumption for regeneration.

The micro-heat regeneration dryer is mainly composed of the following devices including two adsorption cylinders available for being alternatively used, one electric heating device, one sound-muffling system, one set of switch valves, one electrical control system, and gas source processing unit.

1. The heating control device adopts the contactless solid-state switch, with automatic constant temperature control, long service life, and multi-failure warning function.

2. Have the advanced variable program, with stable & reliable operation.

3. Adopt the microcomputer control, able to carry out the digital display for the alternative operation status of two towers.

4. Use the safe & reliable control elements, so as to ensure that the output signal of the controller can safely and accurately reach the instruction objective.

5. Ensure that the dew point of the finished product gas is stable and reliable, with low energy consumption.

6. Have a simple & exquisite structure, with personalized design, convenient for operation and maintenance.

7. When the micro-heat part is faulted, the equipment may be automatically switched to the no-heat operation mode.

8. Select to configure the RS485/RS232 and linked interfaces, able to carry out the remote communication, centralized monitoring and joint control for air compressors.
