General Description

McQuay Magnitude

Centrifugal Chillers are complete, self-

contained, automatically controlled, uid-chilling units featuring

oil-free, magnetic bearing compressors. All Magnitude

chillers

are equipped with a single evaporator and a single condenser

along with either one or two compressors depending on the

model.

Magnitude

chillers are designed for indoor, non-freezing

installation only. The chillers use refrigerant HFC-134a that

operates at a positive pressure over the entire operation range,

so no purge system is required.

Only normal eld connections such as water piping, relief valve

piping, electric power, and control interlocks are required,

thereby simplifying installation and increasing reliability.

Necessary equipment protection and operating controls are

included.

All McQuay International centrifugal chillers must be

commissioned by a factory-trained McQuay International

service technician. Failure to follow this startup procedure can

affect the equipment warranty.

The standard limited warranty on this equipment covers parts

that prove defective in material or workmanship. Specic

details of this warranty can be found in the warranty statement

furnished with the equipment.
