Approximate height of package is 10 feet, 8 1/4 inches (3258 mm) and may vary with ancillary equipment and generator selection. Four lifting gussets are provided on each section.

Drip pans are welded beneath the package frame to collect potential liquid spills. The drip pans also provide a tight seal for containment of fire suppression agent for packages supplied with an enclosure.

Tube Fittings. All tube connections use compression fittings. Tubing and fittings are 316 stainless steel.

Piping. Package piping is designed and fabricated to ANSI B31.3.

Electrical System. The Taurus 60 IPG generator set is designed to comply with the requirements of the National Electrical Code and is intended to be installed in a non-hazardous location per the NEC.

Unless otherwise noted package motors and heaters are rated for 460 Vac, 60 Hertz, 3 phase. Motor space heaters are provided for motors over 5 hp (3.75 kW) and are rated for 120 Vac, 60 Hertz, 1 phase. Except where indicated, contactors and motor starters are not included.

Fire Detection and Suppression System. The gas turbine enclosure will be provided with ultra violet fire detectors and fire monitoring system. The fire suppression system agent is CO2. In the event of a fire being detected within the unit, the unit will shutdown, the enclosure ventilator louvers will close, and horns will sound.

Gas Detection System. Gas detection monitors are provided in the turbine enclosure. Upon detection of 20% LEL, alarms will sound. Upon detection of 75% LEL, the unit will shut down and all louvers will open, and all ventilator fans will activate.

II. GAS TURBINE ENGINE

The Taurus 60 gas turbine engine is a single shaft axial flow engine. The output gearbox, including accessory drive pads, is a separate, close-coupled unit located at the inlet end of the turbine.

The engine assembly consists of:

Gear unit with accessory drive pads

Air inlet collector with flexible flange connection

Axially split case in the vertical plane, eleven‑stage axial flow compressor with variable temperatures.

Geometry control on inlet guide vanes and first two rows of stators

Annular SoLoNOx combustor with 12 lean premix fuel injectors

Three‑stage turbine assembly

Turbine exhaust collector

The components of the Taurus 60 engine are maintained in accurate alignment by mating flanges with pilot surfaces and are bolted together to form a rigid assembly. The speed reducing gear box is driven by the compressor rotor shaft. Accessory pads drive the main lube oil pump and other accessories, depending on the application, and supports the starter motor.

The gas turbine output shaft is mechanically connected to both the compressor and turbine sections of the engine to form a ”solid” or ”single” shaft configuration. This feature enhances speed stability and response under constant and varying load conditions -- a highly desirable feature in generator applications requiring precise frequency control.

A turbine engine cleaning system is provided. The system includes nozzles installed in the air inlet housing and on skid piping and controls. The cleaning system is designed for operation while the engine is cranked by the start motor.

III. SPEED REDUCING GEARBOX
