DBP BLOWER PURGE HEATED DRYER

TECHNICAL DESCRIPTION OF COMPONENTS

Basic devices used in the dryer system are described
in this section. For more detailed additional
information refer to the component bulletins included
in the rear of this manual.

8.1

ADSORBER

An adsorber is a pressure vessel filled with
desiccant. At each end of the vessel are perforated
stainless steel flow distributors and desiccant support
screens. The sole purpose of the support screen is to
retain the desiccant in the vessel and evenly
distribute the process and regeneration flows across
the area of the desiccant bed for optimum drying and
regeneration.

8.2

DESICCANT

For this drying application an Activated Alumina
desiccant is used

8.3

HEATER

The regeneration heater is installed external to the
desiccant beds in an insulated heater housing. It is a
immersion type that is removable from the housing.
The heating elements are made with an incoloy
sheath material. They are attached to the plug by
brazing to ensure a leak free pressure connection is
obtained. For regeneration of this dryer a heater is
provided. A type “K” thermocouple is attached to the
sheath of one element to provide “sheath over-
temperature” protection.

8.4

VALVES

Inlet valves are Piston type Bronze valves, dryers up
to 650 CFM and High performance Butterfly valves
for 800 CFM and up are used for tower switching
and are equipped with a Normally open pneumatic
actuator. Purge Exhaust valves are piston type (up
to 650 CFM) and high performance butterfly valve
800 CFM. Valves are equipped with Spring Load
Normally close actuator. (Note: in case of any power
failure the exhaust valves will be closed and inlet
valve will be open. Fail safe design)

8.5

ACTUATORS

Each valve is equipped with a actuator. Dry
instrument quality compressed air is used for pilot
actuation. A minimum air pressure of 60-80 psig is
required.

8.6

REGENERATION BLOWER

A regenerative centrifugal direct mounted motor is
used to provide the air for regeneration. The blower
is equipped with an inlet filter/silencer to eliminate
any air borne particles eing taken into the blower
impeller system.

8.7

PRESSURE GAUGE

The dryer system is fitted with pressure gauges and
Pressure snubber on each vessel solely for the
purpose of “local” pressure indication. Do not replace
pressure gauges with liquid filled type.
