Page 30: Modes Of Operation
Modes of Operation TrilliumSeries™ Adiabatic Products will operate in two basic modes: Dry Mode and Pre-Cooler Mode. In Dry Mode, the water pump will be off and the unit will operate as an air-cooled condenser or fluid cooler. During Pre-Cooler Mode, the unit will use a pump to deliver water over the Pre-Cooler Pads, making the unit operate as an adiabatic condenser or fluid cooler. - Page 31 Cleansing Circulation Unit Operation TrilliumSeries™ Adiabatic Products utilizes a patented process in Pre-Cooler Mode to manage the water: maximizing Pre-Cooler Pad wetting while minimizing water consumption Modes of Operation and maintaining hygiene. This process is called Cleansing Circulation. Dry Mode In this process, water enters the unit and is circulated throughout, never remaining still.

Page 36: Auto-Discrete Backup Spray System
Auto-Discrete Backup Spray System The Auto-Discrete Backup Spray System provides a backup water system for adiabatic cooling in case of component failure. The system senses if the pump, make-up valve, or float switch fails, and if so, disables the pump and triggers a backup supply of water to spray over the Pre-Cooler Pads. -
