Technical Highlights
Self-contained and fully-enclosed refrigeration system. Fully computerized parameter control equipped with remote communication capability. Module running time is adjusted automatically by the aggregate to keep individual modules to work evenly and in parallel with each other.

Automatic adjustment of the individual module timing: To gain an energy saving of over 30%, better than the single unit operation. Upon the customer request, we can provide any combination of modular dryers from 2 to 10.

Working Principle of Modular Refrigerated Air Dryers

The large refrigerated output modular air dryers are developed and produced to meet the demands for air disposal in large quantity. Up to 10 unit systems can be controlled with 50-100 Nm/min as a unit system.

The most economic operation scheme can be provided based on the actual environment parameters, air parameters and dew point requirements. In this way, flexibility and reliability of the aggregate are raised while the operation expenditure is cut down significantly. This performance can be achieved in two ways as stated below:

1) The number of dryers to be put into service varies with the load variation. This explains why it can cut down energy consumption considerably.

2) The modular aggregate is a composition of many dryers. So, the equipment can still work properly even if one of the dryers breaks down. This explains why it is much more reliable than the conventional refrigeration dryer.

One master computer plus several modules compose the modular refrigeration dryer. The master computer decides how many modules should be put into operation according to the load variation, such as the dew point temperature and the air inlet/outlet pressure difference. The computer will record the service time of each module, and to make sure the service time of each module is roughly the same.

Better than the conventional refrigerated air dryers, the modular refrigerated air dryers are equipped with electric butterfly valve, warning output, master control input, and dew point temperature-too-high output. All these inputs/outputs are integrated with the master computer to form a modular refrigeration dryer controlling system.
