The Turbo Air 3000 Centrifugal Compressor Operator’s Manual
Optional Features
Although the following components are not required for safe operation of the Turbo Air 3000 Compressor,
they will bring added convenience to the overall operation of the lubrication system. If not
included with the initial compressor package, they may be added at any time.
Oil Reservoir Heater
The minimum startup oil temperature for the compressor lubrication system is 60°F (15° C). Therefore,
compressors that are installed outdoors or in unheated buildings may require the use of the Oil Reservoir
Heater option. Such emersion heaters are rated at 1.5 kW and are available in any standard threephase
voltage up to 600 volts. The heater is installed in the oil reservoir. Figure B—3 shows the Oil
Heater option.

Thermostatic Mixing Valve
With the standard package, oil temperature is maintained by regulating the flow of cooling water
through the oil cooler. This method, though effective, may require seasonal adjustments. Including the
Thermostatic Mixing Valve option will automatically control oil temperature by regulating the oil flow
around the oil cooler, thus keeping the temperature of the oil entering the compressor constant. The
Thermostatic Mixing Valve option is shown in Figure B—4.
