RYCOOLERS
Heat Rejection Module
The low-profile direct-drive propeller-fan type drycoolers utilize optimum circuitry to balance the heat rejec-
tion 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 fac-
tory 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.
