Standard large dehumidifiers are semi‐custom: while basic concept and layout is the same, options and specific
systems and components layout and location may vary from one dehumidifier to another. One of the typical
dehumidifier arrangement is shown on Pic.C.1.
Dehumidifier Options
Indoor or outdoor installation.
o
Note:
Pic. C.1. shows outdoor model, equipped with louvers (to protect air intake and discharge
openings from elements). Indoor model would have ducts connected to respective openings, no
louvers would be needed.
Capacity (number of compressors) – two to four compressors (see
Dehumidifier Optional Arrangement
below
for more details):
o
Two‐compressor dehumidifier option (models PPK070 to PPK340).
o
Three‐compressor dehumidifier option (models PPK380 and PPK420).
o
Four‐compressor dehumidifier option (model PPK530).
Airflow/ductwork connection *. Pic. C.1 shows some options only; each option location availability depends on
the dehumidifier installation (indoor or outdoor) and other options:
o
Return Air
(
RA
) ductwork connection ‐ top, bottom, end, sides.
o
Supply Air
(
SA
) ductwork connection – top, bottom, sides.
o
Optional
Min Outdoor Air
(
OA
) ductwork connection/termination – top, sides.
o
Optional
Min Exhaust Fan
(
EF
) and
Purge Fan
(
PF
) ductwork connections/terminations – end, sides.
o
Optional
Purge Outdoor Air
(
POA
) ductwork connection/termination ‐ top, sides.
Optional
Pool Water Heating
**.
o
Dehumidifier can accommodate up to two pool water heating circuits
Optional
Space Heating
‐ hot water coil, electric or gas heater ***.
Optional
Heat Recovery
(HR) circuit.
Air Conditioning
(
AC
)* – external water cooling or fluid cooler (packaged or separate).
o
Note:
Pic. C.1 shows outdoor model with “packaged” fluid cooler (mounted with the dehumidifier).
“Packaged’ AC option is available for outdoor models only; alternatively, indoor and outdoor models
could be fitted for separate/remote AC option – remote fluid cooler or other external cooling media
source.
*
Some available options (tonnage, ductwork connections, AC options etc.) are shown. Refer to the submittal
and other relevant documentation for your dehumidifier’s options.
**
The pool water heating option relies on compressor‐created excess heat and is used as an additional
heating source. It does not eliminate the need for a main pool water heater.
***
For specific details on space heating (hot water, gas, electric) option, refer to the submittal and other
documentation:
Gas‐fired duct heater
can be installed internally (fitted inside the dehumidifier at the factory) or provided for field
installation (to be fitted in the supply air ductwork).
Electric heater
or
hot water coil
, depending on capacity, model, size, etc., can be installed externally (mounted on the
top of SA opening or fitted in the supply air ductwork) or internally. Refer to your dehumidifier’s submittal
documentation.
Attention! Equipment Clearances and Dimensions!
CAUTION!
For equipment proper operation, maintenance and service, respective clearances should be
maintained. Generally, 30” clearances to the equipment must be kept for the maintenance and service purposes.
For the specific required clearances information, as well as dehumidifier overall dimensions, distances to pipe
connections, duct connections etc., refer to the submittal documentation.
