Environmental Control<br />
A well designed indoor swimming pool will provide years<br />
of pleasure for its owner. The Delta range of heat recovery<br />
dehumidifiers are specifically designed to economically<br />
provide the environmental comfort and moisture related<br />
structural protection expected of such a pool.<br />

Why Calorex<br />
Calorex is the Worlds leading<br />
manufacturer of swimming pool heat<br />
pumps and is renowned for its<br />
innovation, range and quality of<br />
product. a proud claim, backed by over<br />
thirty years of design, manufacture and<br />
operational experience with thousands<br />
of units operating in over 60 countries<br />
worldwide.<br />
What does it do<br />
The Delta, connected to a suitably sized<br />
boiler will provide the complete<br />
solution to humidity, water/air<br />
temperature control and fresh air<br />
demands.<br />
Our product is our reputation. And both are the best.
The Delta range is now further enhanced by<br />
introduction of the high capacity Delta 14 &<br />
16. Designed for commercial pools, the Delta<br />
14 and 16 are available with over 40<br />
different airflow and control panel<br />
configurations, allowing them to provide<br />
total flexibility for all shapes and sizes of<br />
plant rooms.<br />
Backward curved fans designed to operate<br />
against high external resistances are fitted<br />
as standard and the unit can be supplied<br />
with BMS for buildings with central control.<br />
gned for all indoor pools<br />
Humidity control<br />
In contrast to most buildings, indoor swimming pools<br />
constantly evaporate large volumes of moisture into the<br />
space around them. Unless this moisture is removed,<br />
humidity will rise creating an uncomfortable environment<br />
and structural/fabric damage. Totally self controlling, the<br />
Delta will remove this moisture and recover energy from it<br />
which is then re-used to assist water and air heating. By<br />
utilising this method, a heat cycle is created and energy<br />
costs are kept to a minimum.<br />
Pool water and air heating<br />
A majority of the heating needs are provided by heat<br />
recovery from the dehumidification process. Heat losses<br />
that cannot be recovered are provided for by inbuilt heat<br />
exchangers which are connected to hot water from a<br />
boiler. All necessary controls to accurately maintain stable<br />
temperatures are fitted as standard within the Delta. This<br />
ensures easy installation with a central user friendly<br />
control panel that will automatically interrelate to pool hall<br />
air, water and humidity needs.<br />
Fresh air/air handling<br />
The Delta range is provided with automatically modulating<br />
fresh/exhaust air. This alleviates potential build up of<br />
airborne chemicals, provides a greater degree of air<br />
temperature control during warm weather and allows a<br />
slight negative pressure to be created within the pool<br />
hall which will prevent migration of pool hall air to<br />
adjacent rooms.<br />
During the cold weather, energy will<br />
be recovered from exhausted air to<br />
reheat the fresh air supply. With<br />
models 4 to 16, this process will<br />
automatically reverse during hot<br />
weather to reject some excess<br />
energy to the exhaust air and<br />
consequently maintain a<br />
comfortable temperature within the<br />
building.<br />
Controls<br />
The Delta is fitted with easy to read<br />
humidistat, and air and water<br />
thermostats, each with LCD<br />
display of set point and<br />
actual measured data. A<br />
simple diagnostic light<br />
system allows the<br />
user to read the<br />
operational mode,<br />
and a 7 day timeclock<br />
controls<br />
Delta operation.<br />
All controls are<br />
located and easily<br />
viewed behind a<br />
hinged protective<br />
screen.
