1.1System Descriptions

Challenger 3000environmental control systems are available in three main system configurations:

self-contained system with a scroll compressor in the room unit

self-contained chilled water system

split system with an evaporator section and a remote condensing unit

All three types are available in upflow or downflow configurations. The standard upflow configuration is front return. All models require three-phase power. Units are available in 208, 230, 460, or 575V, 60Hz; and 200, 230 or 380/415V, 50Hz.

The following features are included as standard in all room units regardless of the type of system: Lie- bert iCOM control, A-frame coil (V-frame on upflows), infrared humidifier, finned tubular stainless steel electric reheat, 2" filter, individual high voltage fused protection and fan assembly.

1.1.1Self-Contained Systems Air-Cooled Models

Complete refrigeration system including hot gas bypass and crankcase heater with standard scroll compressor, standard condenser and fan speed control for 95°F (35°C) ambient at sea level. Optional Digital scroll compressor with unloading solenoid valve is also available. Digital scroll compressor systems do not include hot gas bypass.

Water-Cooled Models

Compete refrigeration system including hot gas bypass with standard scroll compressor, water/glycol- cooled condenser and two-way water regulating valve with bypass. Optional digital scroll compressor with unloading solenoid valve is also available. Digital scroll compressor systems use a 2-way motor- ized ball valve in lieu of the regulating valve; they do not include hot gas bypass.

Glycol-Cooled Models

The water-cooled model as described above plus pump package and 95°F (35°C) design ambient dry- cooler.

GLYCOOL Models (5-Ton Only)

Complete refrigeration system including hot gas bypass with standard scroll compressor, glycol con- denser and three-way water regulating valve plus an integrally piped Econ-O-Coil with three-way mod- ulating control valve. Optional digital scroll compressor with unloading solenoid valve is also available. Digital scroll compressor systems use a 3-way motorized ball valve in lieu of the regulating valve; they do not include hot gas bypass.

1.1.2Chilled Water Models

Chilled Water models include chilled water piping, three-way modulating valve, and actuator assem- bly.
