Gas Suppression Agents - FM200, NOVEC 1230, INERGEN
A comprehensive comparison of the primary clean agents used in modern gaseous fire suppression systems. Selecting the correct agent depends on room occupancy, space availability, environmental specifications, and structural requirements.

Where Gas Suppression Is Required
Water-based fire fighting systems can damage high-value assets and electronics, causing severe downtime. Clean agent gas suppression systems are mandatory or highly recommended for the following critical environments:
Electronic equipment cannot tolerate water or dry powder.
Critical power infrastructure requires non-conductive, clean agent fire suppression.
Protects core industrial process control electronics and operations centres.
Continuous operation is critical for core communication systems.
Protects irreplaceable paper documents, blueprints, and digital media.
Protects rooms where specialized rapid fire suppression is required.
Used where dry chemical is unacceptable for product quality.
Preserves high-value, irreplaceable historical assets and artwork.
Protects main electricity panels and Motor Control Centres.
Critical Design Requirements
Gas suppression system design is engineering - not guesswork. An undersized system will not extinguish the fire. An oversized system wastes agent and increases cylinder storage requirements. The following must be calculated and documented for every installation:
Enclosure volume
Precise internal volume measurement including dead space above false ceilings and under raised floors.
Design concentration
Agent-specific minimum concentration required to extinguish fire (confirmed by agent manufacturer test data).
Leakage rate
Evaluates door perimeter sealing, cable penetrations, structural joints, and HVAC damper closure reliability.
Enclosure integrity test
Door fan pressure test (EN 15004 / NFPA 2001) confirms the enclosure holds agent concentration for a minimum of 10 minutes.
Nozzle placement
Uniform agent distribution throughout the protected volume, accounting for structural obstructions and beam depths.
Cylinder sizing
Total agent quantity calculated from volume × design concentration × fill density and altitude correction factors.
Pipe sizing
Flow calculations to ensure simultaneous nozzle discharge within the specified time (typically 10 seconds for FM200).
Pressure relief vent
Required to prevent enclosure structural damage from sudden pressure peaks during agent discharge.
Installation Process
We follow a disciplined, rigorous engineering workflow to ensure every clean agent gas suppression installation is fully documented, completely safe, and built to last.

Standards and Compliance
Every gaseous fire suppression system we design, install, and service is engineered in strict compliance with national and international standards to ensure maximum safety, reliability, and smooth fire NOC approvals.

TAC Guidelines
Insurance Advisory
Tariff Advisory Committee standards outline fire protection requirements that facilities must implement to meet commercial insurance criteria and secure premium discounts.
Kitchen Hood Suppression Systems
Commercial kitchen fires in grease-laden exhaust ducts and hood areas represent one of the highest-risk fire scenarios in the food service industry. Wet chemical kitchen suppression systems are specifically designed for this hazard. On activation, the system discharges wet chemical agent onto cooking surfaces and into the exhaust duct - simultaneously triggering automatic gas fuel shut-off and exhaust fan shutdown.
We install kitchen hood suppression systems for restaurants, hotel kitchens, institutional canteens, food production facilities, and cloud kitchen operations across Gujarat.
Tube-Based Direct Release Suppression
For smaller enclosed equipment - electrical panels, CNC machine enclosures, transformer bays, battery storage rooms, and generator compartments - tube-based suppression systems offer a compact, self-contained solution.
The suppression tube (filled with agent under pressure) runs through or around the hazard. When exposed to heat or flame, the tube bursts at the hottest point and directly discharges agent onto the fire source. No control panel, no external power, no delay.
Maintenance and Recharge
Gas suppression systems require annual inspection and periodic agent weight checks to confirm cylinder integrity. We provide full-service support including:
Frequently Asked Questions
Have questions about gas suppression system design, standards, or installation requirements? Find answers to commonly asked questions below:
FM200 (HFC-227ea) is not currently banned in India. However, it has a high Global Warming Potential (GWP of 3220) and is subject to phase-down under the Kigali Amendment to the Montreal Protocol. For new installations where environmental performance is a priority, NOVEC 1230 (GWP of 1) is the preferred alternative. Existing FM200 systems are not required to be replaced.
The protected enclosure must hold the design concentration of suppression agent for a minimum of 10 minutes after discharge. This is verified by a door fan (enclosure integrity) test conducted before commissioning. Inadequate sealing around cable penetrations, doors, and HVAC openings is the most common reason for failed integrity tests.
FM200, NOVEC 1230, and INERGEN (at correct design concentrations) are classified as safe for use in normally occupied spaces. However, a pre-discharge alarm and evacuation time delay (typically 30–60 seconds) is always provided to allow occupant evacuation before agent release. Agent discharge should never be inhibited when the area is unoccupied.
Accidental discharge in an occupied room requires immediate evacuation and ventilation. The suppression agent itself is not acutely toxic at design concentrations but displaces oxygen at high concentrations. Ventilate the space thoroughly before re-entry. The system must be recharged before it provides protection again.
Cost depends on protected volume, agent type, number of nozzles, and integration requirements. A single server room of 20–40 sq.m. with FM200 typically ranges from ₹1.5 lakh to ₹3.5 lakh installed. Larger installations scale with volume and complexity. We provide detailed quotations after a free site survey.
Yes. Gas suppression systems use dedicated cross-zone detection within the protected enclosure - typically two independent detector types or two independent detection circuits. This cross-zone logic (both zones must activate) reduces accidental discharge. The detection can be standalone or integrated with the main building fire alarm system.
A single server room system (20–50 sq.m.) takes 3–5 working days from start to commissioning. Larger multi-zone systems or systems requiring significant pipework may take 2–3 weeks.
An enclosure integrity test (door fan test) measures the leakage area of a protected enclosure by pressurising and depressurising it with a calibrated fan. The test result is used to calculate whether the enclosure can retain agent at design concentration for the required 10-minute hold time. It is a mandatory pre-commissioning requirement per NFPA 2001 and EN 15004.
