Gas-Based Fire Suppression Systems

In a server room, a data centre or a switchgear room, water does as much damage as the fire. Spray a rack of live equipment and you’ve turned a small incident into a total write-off. That’s the problem gas-based fire suppression solves. It floods the room with a clean agent( non conductive gas) or an inert gas that puts the fire out in seconds and leaves no residue, so your equipment survives the save.

These systems protect the spaces where downtime and lost data cost far more than the building itself. They’re also the systems most often installed once and forgotten, right up until a discharge that doesn’t hold, or an inspection that fails.

Zap Fire designs, installs and maintains gas suppression systems for data centres, industrial and institutional clients. We’re headquartered in Gurugram and we run projects for clients across India. We’ve done this since 2008, and we cover the whole job, from agent selection and concentration design through to the annual tests that prove the system still fires.

What a gas suppression system includes

A total-flooding gas system is a chain of parts that has to act in the right order, fast:

Agent cylinders and manifold

Agent cylinders and manifold

High-pressure cylinders, single or banked on a manifold, holding enough agent to flood the protected room.

Discharge nozzles and piping

Discharge nozzles and piping

Engineered pipe runs and nozzles that spread the agent evenly across the space within seconds.

Detection

Detection

Cross-zoned smoke and heat detection that confirms a real fire before release, so the system doesn't dump agent on a false alarm.

Release and control panel

The dedicated panel that reads the detection, runs the countdown and fires the system.

Manual release and abort stations

Manual release and abort stations

Manual actuators to trigger a discharge, and abort switches to hold it while people clear the room.

Alarms and signage

Sounders, strobes and discharge warning signs, so nobody is inside when the gas drops.

Auxiliary shutdowns

Auxiliary shutdowns

Interfaces that trip the HVAC, close dampers and shut down equipment so the agent stays in the room.

The agents we work with

We design around the agent that fits your room and the people who work in it:

The agents we work with

Water-based suppression is off the table in these rooms. It conducts electricity and wrecks the very equipment you’re trying to protect.

01

FM-200 (HFC-227ea)

A halocarbon clean agent that suppresses fire by absorbing heat. A fast, compact agent that’s safe for occupied spaces like staffed server rooms.

02

NOVEC 1230 (FK-5-1-12)

A clean agent stored as a liquid, with the lowest environmental footprint of the group. Non-conductive and residue-free, suited to data centres and high-value electronics.

03

Inert gas (Inergen / IG-55)

Nitrogen and argon blends that drop oxygen below the level fire needs, while staying breathable for anyone still in the room.

04

CO2.

A cost-effective flooding agent for unoccupied spaces only, since it works by removing oxygen. We design it with strict evacuation and lockout controls.

Concentration and enclosure integrity

A gas system only works if the room holds the gas. NFPA 2001 requires the agent to stay at its design concentration for at least 10 minutes after discharge, long enough to put the fire out for good. If the room leaks through unsealed cable entries or gaps under doors, the agent drains away and the fire can reignite the moment it’s gone.

That’s why we run a room integrity test, the door fan test, on every total-flooding system. It measures how tightly the enclosure holds pressure and predicts how long the agent will stay put. We seal what needs sealing before we sign off, and we re-check it under AMC, because rooms change as cables and equipment get added. 

A clean agent system that discharges into a leaky room empties your cylinders and saves nothing. Zap Fire runs the door fan test so your room actually holds the agent long enough
to work.

Services we provide

Gas suppression is precision work, and we cover every stage of it with our own engineers and crews. 

After a discharge, or every year at the cylinder weigh-in, the question never changes: will it fire when you need it? A Zap Fire AMC makes sure of it, with the functional test on record. Email

Built to Indian and international codes

We design and install to the codes that govern gaseous suppression: 

Designing to these is about more than approval. It’s what keeps an inert system breathable for the people in the room, and keeps a CO2 system from discharging while anyone is still inside. 

Where we install gas suppression

We design and maintain gas suppression for clients across India, in spaces such as: 

Server rooms and data centres

Electrical rooms, LT and HT panels

UPS and battery rooms

Telecom and control rooms

Archives, records rooms and libraries

Museums and high- value storage

Generator and turbine enclosures

Switchgear and transformer rooms

Why building owners choose Zap Fire

These systems sit silent for years and then have to perform once, perfectly. That’s the standard we build and maintain to. Here’s what you get with us:

Agent matched to the room

We pick the gas around your space and the people in it, not a one-size default.

Room integrity built in

Door fan testing on every total-flooding job, not an afterthought once the cylinders are up.

One team from design to AMC

The people who design your system are the people who maintain it.

In-house engineers

Trained on clean-agent and inert-gas systems, not general site labour.

ERP-tracked service

Every cylinder weigh, functional test and integrity check logged and ready.

A partner since 2008

Turnkey gas suppression delivered across India.

Frequently asked questions

1
FM-200, NOVEC 1230 or CO₂, which gas suppression agent do I need?
FM-200 and NOVEC 1230 are clean agents suitable for occupied spaces such as staffed server rooms. CO₂ systems are designed for unoccupied areas only, as they suppress fire by reducing oxygen levels. We recommend the right agent after assessing your room conditions, equipment, and occupancy requirements.
2
Is gas suppression safe for people?
Clean agents and inert gases are designed to be safe at their approved working concentrations in occupied rooms. CO₂ systems require strict evacuation procedures and safety controls because they reduce oxygen levels. Every system is designed with the safety of occupants as a priority.
3
What is a door fan test, and do I need one?
A door fan test measures how effectively a room can retain the extinguishing agent after discharge. NFPA 2001 requires the agent concentration to be maintained for a specific period, typically 10 minutes, making testing essential for total flooding systems. We also repeat testing during AMC when room conditions change.
4
Do you refill cylinders after a gas suppression discharge?
Yes. After a discharge, we refill or replace the extinguishing agent, reset the system, test all components, and re-commission the system to ensure complete protection is restored quickly.
