Chilled Water System—Standard and Optional Features

5.0CHILLED WATER SYSTEM—STANDARD AND OPTIONAL FEATURES

5.1Chilled Water System—Standard Features

5.1.1Cooling Coil

The chilled water cooling coil is designed for closed-loop applications using properly maintained water. It is constructed of copper tubes and aluminum fins. To ensure quality, the V-frame coil is manufactured to the highest standards in the industry.

5.1.2Modulating Motor

The flow of chilled water through the cooling coil is controlled by an electronic modulating motor. The microprocessor control will activate the motor when a need for cooling or dehumidification exists. The motor will position the valve to precisely match the needs of the conditioned space.

5.1.3Line Insulation

All chilled water piping within the Liebert Challenger ITR is fully insulated to assure full system capacity and prevent condensation.

5.1.4Three-Way Control Valve

The fully insulated control valve gives the conditioned space the precise cooling needed by electronic equipment. Its unique design requires no overtravel linkages and never requires adjustment.

5.2Chilled Water System—Optional Features

5.2.1Chilled Water Flow Switch

The flow switch will activate the alarm system and/or shut down the system should the chilled water supply be interrupted. The switch is factory wired and mounted in the chilled water valve compart- ment.

5.2.2High Pressure

For special applications, a high-pressure, modulating three-way or two-way valve can be provided. The valve is designed for 400 psig (2758 kPa) water pressure.
