The Gielle Systems are automatic suppression systems using Novec 1230 Fire Protection Fluid and consisting of four basic components and their associated accessories.

System Components
Completer Kits
Detection and Alarm Devices
Control Panels

The system components consist of agent containers, container supports (racks), and discharge nozzles.

The completer kits consist of warning signs, hoses, connection fittings, pressure gauges or solenoid valves, and the actuator required to operate the cylinder valve.

The detection, alarm devices and accessories provide fire detection, audible and visual pre-alarm warnings and annunciation of the Novec 1230 fluid discharge.

The control panel monitors the detection, actuates the alarms, initiates the agent discharge and controls auxiliary functions such as shut down of vital equipment and ventilation dampers.

The system and its components are agency tested for total flooding applications and should be used in accordance with the guidelines contained in National Fire Protection Association 2001. A total flooding application can be defined as injecting Novec 1230 fluid into an enclosure or volume having the structural integrity to retain the agent during and after discharge. The design of such a system requires that the Novec 1230 fluid be discharged from its container in between a minimum of 5 and a maximum of 10 seconds and be thoroughly mixed throughout the protected volume, reaching a minimum concentration level of 4.2%, but not exceeding 10% in normally occupied spaces.

Novec 1230 Fire Protection Fluid is a highly efficient fire extinguishant designed especially for "special hazards." These are defined as spaces — such as telecommunication switch rooms, computer and electronic control rooms — where maintaining continuous operation of high-value equipment is critical.

Novec 1230 Fire Protection Fluid is a highly-effective clean extinguishing agent that: 
Evaporated cleanly and completely during discharge 
Leaves no residue for clean up 
Is electrically non-conductive, non-corrosive and compatible with most metals, plastics and elastomers 
Is ideal for protecting high value assets such as electronics, electronic media and delicate mechanical devices that are vulnerable to conventional water, foam and dry chemical extinguishing agents 

Safety Advantages:
Special hazards applications typically include the presence of people, so life safety becomes a critical issue. Novec 1230 Fire Protection Fluid's low toxicity and wide margin of safety gives occupants more time to evacuate the area after a system discharge.

Environmental Profile: 
Non ozone-depleting 
Five-day atmospheric lifetime 
Global Warming Potential of 1 
This environmental profile is unmatched by any other halogenated agent, and helps make Novec 1230 Fire Protection Fluid today's long-term solution for protecting high value assets.
