Water/Glycol-Cooled Systems—Standard and Optional Features

8.4Water/Glycol-Cooled, Split System—Optional Features

High Pressure

The high pressure option for the condenser circuit consists of a two-way or three-way water regulat- ing valve and condenser rated at 350 psig (2413 kPa) water pressure. This option is required in appli- cations with large static heads.

Factory Installed Non-Fused Disconnect Switch

Allows unit to be turned off for maintenance. Disconnect switch is available on indoor condensing units only.

70/30 Cu-Ni Econ-O-Coil

This coil replaces the standard copper tube coil to provide improved resistance to corrosion. This option must be specified whenever a GLYCOOL or Dual Cooling Source system is applied to a cooling tower loop or other open water system.

8.4.1Glycol-Cooled System—Heat Rejection Devices

8.4.2Self-Contained and Split Systems Fan Speed Control Drycooler

The Liebert manufactured Fan Speed Control drycooler is constructed of aluminum and features cop- per tubes and aluminum fin design. It is low profile, propeller fan type and provides quiet, trouble free heat rejection. The drycooler features a variable speed fan motor and a specially engineered solid state fan speed transducer. The transducer senses the temperature of the leaving glycol and modu- lates the speed of the fan to maintain proper glycol temperatures. An integral, factory-wired and tested control panel reduces installation time.

Glycol Pump

The glycol system includes a matching centrifugal glycol pump. It is mounted in a vented, weather- proof enclosure. Optional Equipment—See page 16.
