Solar offers integrated compressor set packages with the Saturn 20 driving Solar centrifugal gas compressors, designed for long-term operation and conforming to API 617 standards.

Solar compressors feature vertically split barrel-type construction, tilt-pad bearings, and modular rotor construction for easy maintenance and economic feasibility.

The seal gas system includes primary and secondary gas face seals to prevent process gas escape, with air or nitrogen as separation gas to isolate lube oil.

This system uses a circumferential buffer air or nitrogen seal to separate compressor bearing lube oil from dry gas seals.

Compressor casings and end caps undergo hydrostatic pressure testing per API 617 at 1.5 times the maximum casing design pressure.

The standard shaft interconnect is a Kop-Flex dry coupling, with preliminary alignment done at the factory.

The Saturn 20 gas turbine mechanical-drive package is versatile for driving various equipment, offering unitized and non-unitized packaging options.

The gearbox is designed for continuous-duty operation, matching turbine output speed to compressor requirements.

The start system provides torque for engine rotation, using either a direct-drive AC starter motor or a solid-state variable frequency drive.

The Direct-Drive AC start system features a squirrel cage, three-phase AC induction motor with a solid-state variable frequency drive.

The VFD controls motor speed, gradually increasing until the gas turbine reaches purging speed, then activating the fuel system.

The starter motor provides high breakaway torque and acceleration, with explosion-proof features and over-temperature protection.

The VFD controls motor speed with pulse-width modulated power, designed for non-hazardous locations.

The system requires customer-furnished three-phase AC input, with additional wiring connecting the VFD to the starter motor.

Key specifications include a voltage input range of 380 to 460 VAC, a power factor of 0.96, and an efficiency of 98%.

The pneumatic start system uses process gas or compressed air, consisting of a strainer, shutoff valve, and pneumatic starter motor.

The fuel system controls ignition and fuel flow, with configurations for gas fuel and conventional combustion.

Acceptable fuels include natural gas and propane, with specific pressure and flow requirements.

The lubrication system circulates oil to the gas turbine and driven equipment, maintaining optimal temperature with a thermostatic control valve.
