1.3 PERSONNEL QUALIFICATION
The personnel involved in operation, maintenance, inspection, and assembly must
have the corresponding qualifications to do this work. Areas of responsibility and
supervision of the personnel must be precisely established by the operator. Should
the personnel not possess the necessary knowledge, then they must be trained and
instructed. If need be, this training may be carried out by the manufacturer / supplier
at the request of the operator of the adsorption dryer. Further, the operator is to
make sure that the personnel completely understand the contents of the technical
manual.

PRODUCT INFORMATION
The adsorption dryer is used for the purpose of drying compressed air and other
gases according to its respective design. As a "standard model" the adsorption dryer
is equipped with two desiccant vessels and, depending on certain conditions,
provides pure, dry and oil-free compressed air or gases.
1.4.1 Theory of Operation
The HC heat-of-compression dryer uses the hot air from the compressor to
regenerate the desiccant. Each tower is sized for a minimum of 4 hours online,
but may be extended by use of the optional DPDS which will allow the dryer to
switch towers based on water load rather than time.
The DPDS (Dew Point Demand System) is optional equipment and may or may
not be present on this particular air dryer. If the dryer is equipped with the DPDS,
see the associated DPDS Instruction Manual included in Section 7 for more
operational details.
The regeneration cycle is split up into three functions.
