4.2 Function
4.2.1 Functional principle
The operation of the dryer is intended to ensure a uniform, uninterrupted supply of compressed air of
the required specification.
The function is implemented with 2 or 4 air reservoirs that operate in alternating operating cycles.
While air is being dried in one air reservoir or pair of air reservoirs, the drying agent can regenerate in
the other air reservoir or pair of air reservoirs.
The air flow is routed through the drying agent cartridge of an air reservoir. This extracts moisture from
the air flow. A small amount of the dry air is supplied to the other air reservoir as purge air. The purge
air flows through the drying agent cartridge, escapes into the environment via a drain valve and thus
regenerates the drying agent.
The regeneration cycle lasts 120 s. The associated drain valve is then closed. As a result, the regener-
ated air reservoir with purge air is brought to system pressure and can switch to the operating cycle.
After a further 50 s, the regeneration cycle of the other air reservoir is started at the start of the new
operating cycle.
