 Viking Dehydrator:
The Viking Dehydrator is a manually regenerated desiccant-
type air dryer. The desiccant acts as a moisture indicator by
changing color, and is visible through the required bowl
guard and transparent plastic bowl.
Technical Information:
1. The desiccant is silica gel having a –45
o
F. (-43
o
C) dew
point at a maximum of 90
o
F (32
o
C) temperature with a
regeneration temperature of 350
o
F (177
o
C). When the
silica gel color changes from dark blue to light pink or
clear, it has become saturated with moisture and must
be changed.
2. The unit has a drying capacity of 4400 standard cubic
feet (124,6m
3
) of air to –45
o
F (-43
o
C) atmospheric dew
point at rated specifications before the desiccant
becomes saturated.
3. The maximum air flow rating is 10 standard cubic feet
per minute (0,283m
3
/minute) at 100 psi (689.5 kPa) per
unit.
4. All ratings are based on 70
o
F (21
o
C) saturated inlet air
temperatures at 100 psi (689.5 kPa).
5. The polycarbonate plastic bowl holds 1.64 pounds (0,74
kg) of desiccant and is rated for a maximum temperature
and pressure at 125
o
F (52
o
C) and 150 psi (1034 kPa).
6. The silica gel desiccant is provided in a sealed 1.75
pound (0,794 kg) bag and is shipped in a box inside the
unit cabinet.
7. The unit is to be used on compressed air service only.
Operation of Dehydrator:
The plastic bowl of dehydrator is filled with silica gel. As the
relative humidity increases, the silica gel absorbs the
moisture and begin to change color from dark blue to light
pink, indicating the desiccant must be replaced.
To Make Dehydrator Functional:
Drain valve (E12) shall be closed.
To Drain Dehydrator input line:
CLOSE air shut-off valve (E14). OPEN drain valve (E12) to
drain input line then close it. OPEN air shut-off valve (E14).
To replace Dehydrator cartridge:
Once it has been drained, CLOSE the Dehydrator air shut-off
valve (E14).
Unscrew both the bowl guard and the transparent bowl.
Replace desiccant with a fresh charge.
Follow instructions described on Viking data sheet no. 276
(Form No. F_042089) provided with the silicagel recharge.
