This cabinet type 120L red HFC-227ea gas suppression system packages a full total flooding installation into one lockable steel enclosure, making it the practical choice for server rooms, telecom shelters and small technical spaces where a pipe network would be over-engineered and over-priced. Inside the cabinet, a 120 litre red cylinder holds up to 114 kg of HFC-227ea clean agent at 2.5 MPa, together with the release valve, flexible discharge hose, solenoid actuator, pressure gauge and the detection and control board.

The unit operates as a standalone zone: smoke and heat detectors watch the protected room, the panel confirms the alarm, a 30 second delay allows occupants to leave, and the agent floods the enclosure in under ten seconds, extinguishing the fire without leaving residue on circuit boards, cable trays or documents.

• All-in-One Cabinet Architecture: Cylinder, valve, hose, nozzle, detectors and release panel share a single 550 x 550 x 1900 mm enclosure, which cuts floor space, cabling and commissioning time compared with a piped multi-component system.
• 120L Red Cylinder with Visible Gauge: The red epoxy cylinder is mounted behind a glazed door so that pressure can be read during a walk-round inspection without opening the cabinet or interrupting protection.
• Modular Expansion to Dual Zone: Two 120L cabinets can be linked to a common release panel to protect adjacent rooms, so a growing server hall can be extended zone by zone without replacing the original unit.
• Fast Total Flooding Discharge: A matched valve and nozzle set discharges the complete charge in ten seconds or less and maintains an extinguishing concentration long enough to prevent re-ignition of Class A and Class B fuels.
• Safe for Occupied Rooms: HFC-227ea has a no observed adverse effect level of 9 percent by volume, well above the design concentration used for these rooms, and it is electrically non-conductive, so it can be discharged while staff are evacuating and while equipment remains energised.
• Low Maintenance Standalone Control: Self-diagnosing electronics supervise detector loops, battery backup, solenoid continuity and mains failure, reporting faults locally and to an optional building management contact.

The unit is designed for compact, high-value rooms that sit inside a working building: server and network rooms, telecom base station shelters, UPS and battery cabinets, substation control rooms, laboratory instrument rooms, hospital equipment suites, archive and document stores, library stack areas, small clean rooms and control cabins on production lines. It is equally suited to retrofit projects, because the cabinet needs only a floor anchor, a 220V supply and a wall penetration for the discharge nozzle, and it can be installed while the surrounding facility stays in operation.

Every cabinet leaves the factory pre-piped, pre-wired and pressure tested, with the nozzle position matched to the room volume declared on the order. Site work is limited to anchoring, power connection and a discharge test of the actuator circuit. The cylinder is refillable after a genuine discharge, the solenoid and detectors are plug-in replaceable, and the control board logs alarm and fault history for maintenance review. A five-year quality guarantee applies to the cylinder and valve, supported by eight-hour technical assistance on working days.

Systems ship in a plywood outer case with bubble bag wrapping and paper edge protection, strapped and sealed against moisture for container transport. Each unit is accompanied by an agent filling certificate, a hydrostatic and leak test report, a wiring diagram and an English installation manual. Standard lead time is 15 to 20 working days after payment or L/C confirmation, and annual capacity exceeds 30,000 sets, allowing mixed container loads with other fire fighting equipment from the same factory.
