Titan 250 Generator Set

 

 

11.2Standard Features

11.2.1Inlet and Exhaust Ventilation Silencers

The enclosure ventilation openings are equipped with silencers with weather louvers.

11.2.2Single-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.

11.2.3Enclosure 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.

11.2.4Pressurization 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.

11.2.5Lighting

Fluorescent lighting is provided to illuminate the enclosure interior. Lighting on/off switches are provided on the enclosure exterior.

11.2.6Sound 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.”

11.3Optional Features

11.3.1Enclosure Configuration

An enclosure can be selected to house both the gas turbine and generator or only the gas turbine.

11.3.2Dual 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
