LIEBERT DRYCOOLERS

Liebert drycoolers are designed to be used in conjunction with water cooled refrigeration and air conditioning machines as well as a variety of commercial and industrial applications requiring the rejection of heat from machinery or processes via a cooling fluid. During periods of low ambient temperatures, drycoolers may assist or replace the capacity requirements of mechanical chillers for a “free cooling” effect.

Liebert offers a full range of control options as well as expansion tank and pump packages. For cooling fluids other than water or water/glycol mixtures, contact Liebert, Heat Transfer.

FEATURES AND BENEFITS OF LIEBERT DRYCOOLERS

Heat Rejection Module

The low-profile direct-drive propeller-fan type drycoolers utilize optimum circuitry to balance the heat rejection of the corresponding load. Constructed of aluminum with a copper-tube aluminum coil, the unit is quiet and corrosion resistant.

Low Noise Level

All Liebert drycoolers are designed to operate at a minimal noise level. This is accomplished as the result of the Liebert fan blade design combined with a cabinet structure that minimizes air resistance. Quiet-Line models use low speed motors to achieve the quietest unit available.

Easy Installation and Service

The heat rejection module is quickly and easily installed, because all internal wiring is completed at the factory with only electrical connections to be made at the job site.

Maximum Reliability

Because these units are factory wired and tested, start-up problems are eliminated, and reliability of the overall system is greatly increased.
