Turbomachinery Package Specification 
Titan 
250 Generator Set 
11.2 Standard 
Features 
11.2.1  Inlet and Exhaust Ventilation Silencers 
The enclosure ventilation openings are equipped with silencers with weather louvers. 
11.2.2 Single-Fan 
Ventilation 
A single high efficiency motor-driven fan provides enclosure ventilation. The ventilation 
fan provides airflow to ensure the enclosure internal air temperature remains within 
acceptable limits. Fan size can vary depending on the ventilation system filtration 
configuration. Fan motor wiring is terminated at the motor junction box. Enclosure 
ventilation openings are provided to facilitate airflow circulation. For additional ventilation 
or certification requirements, a dual fan ventilation system may be selected as an option. 
11.2.3  Enclosure High Temperature Alarm 
A heat sensor, completely separate from the fire system thermal detectors, is mounted in 
the enclosure. The sensor is set to activate an alarm if enclosure temperature is 
abnormally high. 
11.2.4 Pressurization 
System 
The ventilation airflow through the enclosure can be controlled to provide either positive 
or negative pressure relative to the outside pressure. Hazardous area classifications and 
the applicable codes and regulations will determine the pressurization requirements for 
specific projects. 
11.2.5 Lighting 
Fluorescent lighting is provided to illuminate the enclosure interior. Lighting on/off 
switches are provided on the enclosure exterior. 
11.2.6 Sound 
Attenuation 
The sound-attenuated enclosure is intended for use with suitable gas turbine air inlet and 
exhaust silencing systems in environments where low noise levels are required. 
Enclosure ventilation openings are equipped with silencers to achieve maximum sound 
attenuation. The actual achievable noise reduction is a function of the noise source, 
installation considerations, other equipment in close proximity, and the acoustical 
characteristics of existing buildings and barriers. 
The intent of the enclosure design is to comply with U.S. Occupational Safety and Health 
Administration (OSHA) standards for eight-hour employee exposure. Transmission loss 
of the panels in decibels is available upon request. Further information is available in 
Solar’s publication SPNP, “Noise Prediction Guidelines for Industrial Gas Turbines.” 
11.3 Optional 
Features 
11.3.1 Enclosure 
Configuration 
An enclosure can be selected to house both the gas turbine and generator or only the 
gas turbine. 
11.3.2  Dual Fan Ventilation 
The enclosure can be ventilated with a dual AC motor-driven fan system. The fan motor 
wiring is terminated at the motor junction box. Openings are provided to ensure adequate 
airflow is circulated through the enclosure. For Conformité Européenne (CE) Mark 
certification, the second or backup ventilation fan is mandatory and must be powered by
