TERMINOLOGY

The following descriptions are provided to ensure all 
persons working with the IDSC equipment are familiar with 

the terminologies used.

Basin:

 An assembly located at the base of the unit de

-

signed to hold a volume of recirculated water while pro

-

viding connections for the water recirculation pump, drain, 
and overflow. It is also known as a pan or sump.

Water recirculation pump:

 Closed coupled, centrifugal 

type impeller, with mechanical seal required to circulate a 
specified flow rate of water over the heat exchange coil(s).

Basin section (induced draft unit):

 An assembly com

-

prised of the basin, support columns, air inlet louvers, 
make-up water connection, and other small parts required 
for proper unit operation in the field. The basin section is 
usually shipped separate from the rest of the unit.

Basin section (forced draft unit):

 An assembly comprised 

of the basin, support columns, axial motors/fans, enclosure 
panels, make-up water connection, and other small parts 
required for proper unit operation in the field. The basin 
section is usually shipped separate from the rest of the 

evaporative unit.

Inlet louvers:

 Enables ambient air to enter the unit at the 

basin section, while preventing water from splashing out 
and direct line of sight into the basin during unit operation. 
There are many different profiles, sizes, and materials of 
construction.

Sump/strainer connection:

 Appropriately sized cross-sec

-

tional area, box or pipe, that is greater than or equal to the 
suction connection size of the water recirculation pump.

Strainer:

 An assembly used to catch large suspended par

-

ticles in the recirculating water before entering the water 
recirculation pump. Periodic maintenance is required to 
keep the strainer clean.

Drain connection: 

Appropriate sized pipe, usually MPT,
