MODULAR AIR SUPPLY CONTROL SYSTEM

摘要

The present invention relates to a system and method of controlling air amount and water content of a compressed air reservoir, wherein an interface (20) is provided at a body unit (1) of an air drying device and adapted to provide a connection for at least two of a valve-based pressure control and regeneration module (4), a pneumatic pressure control and regeneration module (8), and an electronically controlled pressure control and regeneration module (10). At least one pressure signal is input via an input port, wherein the at least one pressure signal is received via the input port, before the at least one pressure signal is used for controlling the air drying device.
