Emerson ITR Manuel D’Utilisation

The Liebert manufactured drycooler is constructed of aluminum with a copper tube aluminum fin 

coil. The low profile design features multiple direct drive propeller type fans, balanced to the heat 

rejection load. An integral, factory wired and tested control panel reduces installation time.

For high pressure applications, the GLYCOOL system can be equipped with components rated at 300 

psig (2069 kPa).

Dual Pump Package

The dual pump package features two full size glycol pumps, each capable of providing sufficient flow 

for system operation. A flow switch will sense the loss of flow, should the lead pump fail, and automat-

ically command the standby pump to start. The complete system includes dual pump housing, pumps, 

lead-lag switch and flow switch (for field installation). The dual pump package provides redundancy, 

protecting against costly downtime in the computer room.

Quiet-Line Drycoolers can help your facility meet the strictest noise codes, and do so at less cost than 

traditional drycoolers with acoustical shielding.
