Site Survey Service
The site survey is the first step of a gas fire suppression project — an on-site inspection of the protected space's physical, architectural, and infrastructure conditions that grounds the design in real, verified data.
Gas Fire Suppression System Services
From site survey to engineering calculation, from installation to periodic maintenance — services covering the full lifecycle of a gas fire suppression system.

Gas Suppression System Design and Engineering
Design and engineering is the standards-compliant engineering phase where pipe diameter, nozzle selection, and cylinder quantity are determined from site data through hydraulic flow calculation.
Material Supply Service
Material supply is the sourcing of the cylinders, valves, piping, nozzles, control panels, and detection devices specified in the design, all as internationally certified products.
Gas Suppression System Installation (Mechanical and Electrical)
Electrical and mechanical installation is the physical, on-site build-out of the suppression system's piping, cylinder racks, nozzles, control panel, and detection wiring, executed exactly to the engineering project.
Commissioning and Supervision Service
Commissioning and supervision is the final verification phase where the entire detection-to-release chain of an installed gas suppression system is tested and installation quality is supervised throughout the project.
Room Integrity Construction Service
Room integrity construction is the structural improvement work that physically seals a protected space's wall, ceiling, and floor penetrations so the suppression gas stays inside the volume for the required hold time.
Room Integrity Testing (Door Fan Test) Service
Room integrity testing (the door fan test) uses a fan mounted in the protected space to create a pressure differential, calculating exactly how long the suppression gas will actually remain in the room — without an actual gas discharge.
Hydrostatic Testing and Refill Service
Hydrostatic testing and refill verifies the pressure integrity of gas suppression cylinders at the intervals required by pressure vessel regulations, then refills cylinders that pass and returns them to service.
Gas Suppression System Periodic Maintenance
Periodic maintenance is an on-site inspection service, performed at least twice a year, that checks a gas fire suppression system's pressure levels, detection function, valve condition, and overall readiness to keep it ready to activate at all times.
Fire protection systems
Beyond gas suppression: fire protection for the whole building
While gas suppression protects the critical rooms, we also design, install and maintain sprinkler, fire pump, foam and kitchen hood suppression systems for the rest of the building, so the whole facility is protected under one engineering approach.
Sprinkler (Water-Based) Fire Suppression Systems
Automatic sprinkler systems with water supply, fire pumps, alarm valves and sprinkler heads for whole-building fire protection: design, installation and maintenance.
Fire Pump Systems
Electric, diesel and jockey fire pump sets for sprinkler, hydrant and hose cabinet systems: capacity selection, installation, commissioning and maintenance.
Foam Fire Suppression Systems
Foam suppression for flammable liquid fires: foam concentrate types, low, medium and high expansion, monitors, foam chambers and high-expansion generators.
Kitchen Hood Fire Suppression Systems
Wet chemical kitchen hood suppression for commercial kitchens: automatic protection of cooking appliances, hood and duct; design, installation and maintenance.
How does a gas suppression project run?
A gas suppression system may stand by for years without operating and must then work flawlessly within seconds. That is why every step from survey to maintenance builds on the output of the one before:
- Site survey: the protected spaces' dimensions, occupancy, leakage paths, cylinder room options and existing detection are inspected on site.
- Design and engineering: agent selection, design concentration, hydraulic flow calculation, pipe and nozzle layout and detection zones are defined.
- Material supply: cylinders, valves, nozzles, control panels and detectors are sourced to the approvals specified in the design.
- Installation: pipework, cylinder racks and nozzles, the control panel and detection cabling are installed exactly to the design.
- Room sealing works: cable and pipe penetrations, vents and dampers are sealed so the room can hold the gas.
- Commissioning: the whole sequence from detection to release is verified with function tests, and users are trained.
- Room integrity testing: a door fan test confirms, without discharging gas, that the design concentration is held for the required time.
- Periodic maintenance: cylinder pressure, detection, valves and actuation are checked at least twice a year.
- Hydrostatic testing and refilling: cylinders are pressure-tested at the intervals set by regulation and refilled after a discharge.
What information is needed for a quote?
- Dimensions of the rooms to be protected (length, width, clear height; any floor and ceiling voids)
- Whether people are present, and the type of equipment protected
- Space available for a cylinder room, and any architectural or electrical drawings
- The existing fire detection and alarm system
