Introduction - Seresco NE Series Installation And Operation Manual

1. Natatorium: a facility that
contains an indoor pool,
whirlpool or spa ranging in size
from a small residential
installation to a large commercial
indoor waterpark.
Seresco's Natatorium Dehumidifiers were
developed by a team of industry experts with a
lifetime of experience developed while working
with many thousands of indoor pools. A
natatorium has many critical design issues that
must be fully understood and properly addressed
to ensure years of comfortable and trouble free
operation of the facility.
This booklet contains valuable design guidelines
based on Seresco's extensive knowledge and
experience in solving humidity control problems
in many thousands of indoor pool installations.
Seresco Technologies Inc., manufacturer of the
NE Series of natatorium air quality control
systems is dedicated to providing state-of-the-art
features and design, quality engineering and the
most reliable products in the market.
The environment in a natatorium should be the
same as in any other room in a building:
comfortable and healthy for the occupants and
their activity, and provide good air quality. The
space conditions in a natatorium need to be
precisely maintained in order to maximize human
comfort and health as well as preserve building
integrity. Relative humidity, air temperature,
water temperature and air quality are all key
environmental aspects to control. High relative
humidity levels are not only a problem to bather
comfort and health, but can seriously damage the
building structure possibly leading to building
component failures. Revenues can also be
affected in commercial facilities. Several hotel
chains offer a full money-back guarantee should
the hotel guest have any complaint regarding
their stay.
A properly designed and maintained natatorium
delivers years of pleasure. The first step is to
become familiar with the design challenges and
to understand how to address them. A
Natatorium's overall performance is inversely
proportional to the amount of compromises and
shortcuts taken in the design and construction of
the natatorium.
A Successful Facility.
one of the most notoriously difficult facilities to
design because there are so many critical
considerations that if overlooked develop into
problems with the building structure or complaints
from the occupants. The designer must take a
complete system approach, from basic

Comfort and Health:
levels are very sensitive to temperature and
relative humidity. It is essential that both are
controlled and stable. While temperature control
is generally well understood and mastered by
designers, it is important to recognize what
temperature levels natatorium patrons want. The
space temperatures in a natatorium are unique to
each project and assumptions must never be
made. Fluctuation of relative humidity levels can
be an even greater concern because it has a
direct effect on human comfort and health.

outside the 40%- 60% range can result in
increased human susceptibility to disease from
bacteria, viruses, fungi and other contaminants
that reduce air quality and potentially lead to
