•Installation, operation, and maintenance instructions.

•Start-up and operator instruction service.

•Advanced motor protection.

CenTraVac Motor

The motor provided in the Trane CenTraVac chiller is a specially designed squirrel cage, two pole induction motor suitable for 50 and 60 hertz, three-phase current.

Trane CenTraVac motors are cooled by liquid refrigerant surrounding the motor windings and rotor. Use of liquid refrigerant results in uniform low temperatures throughout the motor, thereby promoting long motor life.

Refrigerant/Oil Pump Motor The oil pump motor is a 120 volt, 50/60 hertz, 3/4 hp, 1 phase motor with protective fusing and panel mounted contactor.

Purge

The purge unit motor is a 120 volt, 50/60 hertz, 3/4 hp, 1 phase motor with integral overload protection and panel mounted contactor.

The use of an air-cooled condensing unit obtains separation temperatures in the purge drum as low as 0°F. Normal operating efficiency does not exceed 0.002 lbs. of refrigerant lost per pound of dry air removed. The purge system can be operated at any time, independent of chiller operation.

Optional Features

Trane offers a selection of optional features to either complete the basic chiller installation or to allow modification for special purpose applications.
