Taurus 60 Compressor Set and Mechanical Drive

 

 

12.2Standard Features

12.2.1Inlet and Exhaust Ventilation Silencers

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

12.2.2Single-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.

12.2.3Enclosure 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.

12.2.4Pressurization System

For completely enclosed packages, the driver section of the enclosure has a negative pressure to prevent the escape of the internal atmosphere through the enclosure seams. The driven section of the enclosure has a positive pressure to prevent the entry of potentially hazardous external atmospheres. A differential pressure switch is provided to indicate an alarm when low enclosure pressure is detected.

12.2.5Lighting

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

12.2.6Equipment Handling Kit

An internal gas turbine and component handling kit is provided that consists of the following:

•Internal maintenance frame trolley rails

•3048-mm (10-ft) external extensions to the maintenance frame trolley rails with support frame (shipped separately)

•Rail hugger chain-fall hoists and trolley

•Internal vertical support beams (shipped separately)

The trolley beam extension allows gas turbine removal through the side of the enclosure. One end of the beam extension attaches to the inside trolley rail; the other end is floor- standing. The gas turbine can be removed through either enclosure side and placed on a truck bed or cart.

12.2.7Sound 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
