Operational Overview Water/Glycol Cooled Model | Emerson XDF

Product Description

2.2Operational Overview - Water/Glycol Cooled Model

The water/glycol cooled XDF model employs a single-stage cooling system rated at 14kW to supply cooling air to the rack-mounted equipment. A bank of fans circulates this cooling air through the elec- tronic equipment in the XDF (see Figure 1).

An evaporator coil extracts heat from the circulating air. That heat is transferred to a brazed plate condenser at the top of the XDF, transferred to the cooling water or glycol solution and is piped out of the unit.

Coolant is piped through the back of the XDF through supply and return pipes with 1" female NPT connections (refer to Figure 2 or Figure 6).

The XDF’s backup ventilation system operates automatically if power fails or if any XDF cooling sys- tem component fails.

If water is used as the coolant, Liebert recommends employing a closed system connected to an exter- nal condensing unit. A closed water supply system protects the XDF from particles and other contam- inants that might reduce cooling efficiency and damage the XDF.
