Turbomachinery Package Specification 
Titan 
250 Generator Set 
an AC source independent from the package power system. This independent power 
source is not provided by Solar. 
11.3.3  Dust Protection System 
The enclosure ventilation inlets are equipped with a single-stage, disposable, barrier-type 
filter unit equipped with a differential pressure alarm switch. The ventilation exhaust 
openings are equipped with back-draft dampers to prevent the entry of dust when the unit 
is not running. 
11.3.4  Dust and Moisture Protection System 
The enclosure ventilation inlet can be equipped with a two-stage filter unit consisting of a 
first-stage vane separator and a second-stage filter. The moisture eliminator section is 
hinged for filter access. The unit is equipped with a differential pressure alarm switch and 
gauge. The ventilation exhaust opening is equipped with back-draft dampers to prevent 
the entry of dust and water when the unit is not running. 
11.3.5 Standby 
Lighting 
Standby lights provide emergency, automatic, and backup lighting inside the enclosure in 
the event of an AC power loss. Power is supplied from the package battery system. To 
avoid battery system drainage, the circuitry includes a shutoff timer. 
11.3.6 Marinization 
Increased stiffening of enclosure structural components and additional flexibility of 
enclosure and flexible joints between the gas turbine and enclosure can be provided. 
11.3.7 Door 
Open 
Alarm 
The enclosure doors can be equipped with a door position switch that will initiate an 
alarm when any enclosure door is not closed securely. 
11.3.8  Fire and Gas System 
Enclosed packages must include a fire and gas control system. The typical fire and gas 
system shown in Figure 22 provides gas monitoring, fire detection, and extinguishing 
agent release using an advanced distributed architecture to monitor gas, heat, and 
optical flame detectors. The system communicates with the Turbotronic 4 control system 
to initiate a shutdown if a fire or a high gas level is detected. On the package exterior, 
indicator lights, strobe lights, and an alarm horn provide system status. A keyswitch is 
provided to inhibit the system and a push button switch is provided to manually release 
the fire-extinguishing agent. 
The primary fire detection system uses multi-spectrum IR (MIR) flame detectors. The 
system includes an automatic optical integrity feature to provide a continuous check of 
the optical surfaces, detector sensitivity, electronic circuitry of the detector-controller 
system, and automatic fault identification with digital display of system status in numerical 
code. The secondary detection system consists of rate-compensated thermal detectors. 
The two detection systems act independently in detecting and reporting a fire. The 
number of detectors may vary depending on the enclosure configuration. 
The fire system control panel provides system supervision (for open circuit, ground fault, 
or loss of integrity), initiates alarm and release of fire suppression agent, and visual 
display of system status. The suppression system agent release is activated 
automatically with release solenoids located on the fire suppression skid. The optional 
CO
2
 or water mist suppression system can also be activated manually by switches 
mounted on the gas turbine enclosure or at the suppression skid. If a fire is detected, the 
fire detectors transmit an electrical signal to the fire system control panel to activate the 
fire alarm and suppression system
.
