Thera® Inert Total Flooding Gas Fire Suppression 200 Bar & 300 Bar
The Thera® Inert Engineered Gas Fire Suppression system provides clean, total flooding fire protection. This advanced system complies fully with NFPA 2001 standards. It holds both UL Listing and FM Approval. Inert gas fire suppression is available in four variants: IG-01, IG-55, IG-100, and IG-541.
System Hardware and Storage
The extinguishing agent is stored in seamless cylinder assemblies. These cylinders are manufactured to ISO-9809 standards and are TPED tested. Cylinders are available in 80-litre and 140-litre capacities. They are pressurised to 200 Bar or 300 Bar at 15 Deg C.
Key system components include:
- Valve Assemblies: Pressure differential valves are available as discharge valves or solenoid discharge valves.
- Actuators: The system includes manual, pneumatic, and pneumatic-manual actuators with safety pins to prevent accidental discharge.
- Discharge Nozzles: Nozzles are available in $180^\circ$ and $360^\circ$ patterns to ensure proper agent distribution.
- Distribution Accessories: Equipment includes constant pressure regulators, manifolds, flexible discharge hoses, actuation hoses, check valves, bleed valves, and pressure gauges.
Key Applications
The Thera® Inert system effectively suppresses Class A, B, and C hazards. It is safe for occupied spaces. Ideal applications include data centres, telecommunication facilities, and power generation plants. Other suitable locations are marine vessels, offshore oil and gas sites, gas turbine enclosures, and archives.
Extinguishing Mechanism and Properties by Agent Variant
Inert gas systems operate by lowering oxygen content below combustion levels. Each variant possesses distinct composition properties:
- IG-01 (Pure Argon): This system utilises IG-01, which is one hundred percent argon. Argon has a slightly lower density than air, fills enclosures completely, and remains in upper areas. High storage pressure allows it to achieve great heights and distances.
- IG-55 (Nitrogen and Argon Blend): This system utilises a blend of fifty percent nitrogen and fifty percent argon. It distributes balanced proportions throughout the protected enclosure.
- IG-100 (Pure Nitrogen): This system utilises one hundred percent nitrogen. Its density is very close to normal air density, which maintains an even mix.
- IG-541 (Nitrogen, Argon, and Carbon Dioxide Blend): This system utilises fifty-two percent nitrogen, forty percent argon, and eight percent carbon dioxide. The carbon dioxide component stimulates human respiration in low-oxygen atmospheres.
Summary
The Thera® Inert system offers reliable, clean fire suppression for critical assets. It combines robust engineering standards with flexible agent options to protect sensitive environments safely.
