1.1System Descriptions

Challenger 3000™ environmental 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 575 V, 60 Hz; and 200, 230 or 380/415 V, 50 Hz.

The following features are included as standard in all room units regardless of the type of system: 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.

Each configuration can operate with either Advanced Microprocessor Controls (A), or Advanced Microprocessor Controls with Graphics (G). A brief description of each, including operational differ- ences, is listed below. Check model numbers to see what is supplied with your unit.

1.1.1Self Contained Systems Air Cooled Models

Complete refrigeration system including hot gas bypass and crankcase heater with standard con- denser and fan speed control for 95°F (35°C) ambient at sea level.

Water Cooled Models

Compete refrigeration system including hot gas bypass with water/glycol cooled condenser and two- way water regulating valve with 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 glycol condenser and three-way water reg- ulating valve plus an integrally piped Econ-O-Coil with three-way modulating control valve.

1.1.2Chilled Water Models

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

1.1.3Split Systems

Each Air Cooled split system consists of an evaporator section and one of the following condensing units.

Prop Fan

Includes scroll compressor, condenser coil, prop fan, high pressure switch, and Lee-Temp head pres- sure control. Unit is designed for outdoor location.

Centrifugal Fan

Includes scroll compressor, condenser coil, centrifugal blower assembly, high pressure switch, head pressure control valve, Lee-Temp receiver and liquid line solenoid valve. Unit must be mounted indoors. Duct flanges are optional.

Each Water Cooled split system consists of an evaporator section and a water/glycol condensing unit, which includes scroll compressor, coaxial condenser, water regulating valve, and high pressure switch. Design pressure is 150 psi (1034 kPa) as standard and 350 psi (2413 kPa) as optional.

Each Glycol Cooled split system consists of an evaporator section, a water/glycol condensing unit (as described above), a pump package, and a 95°F (35°C) design ambient drycooler.
