The adiabatic pre-cooler pads have been treated with an algaecide to minimize the potential for algae growth. In cases where
excessive fouling is observed and is suspected to be interfering with the airflow, the adiabatic pre-cooler pads should be
cleaned and/or changed more frequently.
Biological Control
The TrilliumSeries™ Adiabatic Cooler has been designed to minimize the risk of uncontrolled growth of algae, slimes, and
other micro-organisms such as Legionella through:
1. Adjustable sump water retention time to mitigate standing water
2. Complete drying of the pre-cooling system after each adiabatic cycle
3. Complete draining of all water distribution piping installed on the unit after each adiabatic cycle
NOTICE: Drain all water piping feeding the adiabatic pre-cooler to avoid stagnant water
conditions.
4. Use of potable water supply at temperatures of 68ºF (20ºC) or less, where Legionella is dormant
5. Aerosol free operation
When basic housekeeping practices, and the guidelines for operation and maintenance of this bulletin are followed,
uncontrolled growth of micro-organisms will be avoided.
