Baltimore Aircoil Company Trillium Series Operating And Maintenance Instructions Manual page 28

The pre-cooling media have a front side and a back side and need to be (re)installed in the correct
position to ensure full wetting over the depth of the media and to ensure maximum efficiency. The
GUTTER SYSTEM
Connect bottom water drains of all pre-cooler sections at both sides of the unit to evacuate excess water.
The surplus of water distributed over the adiabatic pre-cooling media during adiabatic operation is collected into a
gutter and drained to the sewer via one or two different drains per pre-cooler side.
8-fan, 10-fan and 12-fan coolers are equipped with 4 separately shipped adiabatic pre-cooling sections, 2 per side.
Each adiabatic pre-cooler section is equipped with a separate bottom drain guaranteeing full emptying and drying
of the gutter system after each adiabatic cycle.
Refer to the table below for the number of adiabatic pre-cooler sections and number of drains per model.
