DEHUMIDIFIER SPECIFICATIONS
Factory certified service companies can now offer pool
operators 24-hour monitoring.
This is the new standard in customer satisfaction and
unit reliability.
Refrigerant Pressure Transducers
Unit mounted pressure transducers allow the operator
or serviceman to access the vital refrigerant pressures
through the operator panel of the microprocessor (or
remotely via the internet) rather than having to connect
a set of refrigerant manifold gauges. This is the most
important operation and diagnostic information for
any refrigeration system and the ability to access this
information at any time is a significant benefit. Systems
without refrigerant pressure transducers require a
service technician to visit and connect gauges anytime
information regarding the refrigeration circuit is desired.
The refrigeration pressure information from these
transducers is used in the control of the Seresco unit.
Seresco is the only company in the industry that uses
real time refrigeration pressure information in their
control sequence. The result is a significantly more
reliable unit.
Refrigerant System Charges
Seresco offers systems with R410A and R407C
refrigerants. These blended refrigerants are expensive
and there are steps the designer can take today
to ensure the owners refrigerant costs in the future
are minimized:
• Specify the maximum total allowable system charge.
• Keep outdoor air-cooled condensers as close to the
dehumidifier as possible.
• Water-cooled or closed circuit fluid cooler unit
configurations have the smallest charges. These units
come with a complete factory charge and require no
onsite refrigeration piping or charging.
Seresco’s Protocol™ Design uses 75% less refrigerant
compared to a traditional split system.
Receiver Refrigerant Level Indicators
Sight glasses mounted on the receiver allow for easy
refrigerant charge adjustment without the expense
of evacuation and weigh-in techniques. Seresco
is the only manufacturer to use this time and money
savings feature.
Direct Drive Plenum Fans With VFD
Direct drive plenum fans with VFD offer the most
efficient means of moving air while using the lowest
possible fan energy. Belt driven systems are a service
and maintenance concern and are an inefficiency that
consumes more energy. VFDs allow for easy supply air
balancing without changing pulleys or belts.
Coated Airside Coils
All coils exposed to the pool air must be corrosion
protected. Seresco fully dips all coils to ensure 100%
of the coil is protected from corrosion with the best
coatings available in the industry.
Warranty
Five (5) year extended parts only warranties on
compressors and airside heat exchangers are generally
a good investment. 10-year coils warranties are also
available but can be costly.
Units connected to WebSentry from start up get a
premium one-year labor warranty in addition to a two-
year parts warranty at no additional cost.
Commissioning
The final performance review of a dehumidifier can
only be completed once the natatorium is operating
at design conditions. Often the initial start up is done
with a cold pool. These facilities require a follow up visit
once the water has reached design conditions. Specify
that a factory trained/certified service company perform
the start up and commissioning. This may not be the
installing contractor.
First Year Labor
If the installing contractor is not doing the unit start up,
specify who should be responsible for the first year
labor warranty.
