Procurement and engineering teams shortlisting a CO2 fire suppression system supplier or a gas fire suppression system manufacturer for an EPC-specified scope need the same three answers: what the container holds, how the system starts, and what arrives with the order. This page uses the supplied 70L 5.7MPa CO2 gas fire suppression system as the reference unit — agent quantity, storage and maximum operating pressures, activation paths, discharge time and operating temperature — so you can line those figures up against your specification before the request for quotation goes out.
Vendor qualification usually fails on gaps rather than on price. These are the questions a technical buyer should put to any gas suppression vendor, with the answer the supplied CO2 system supports.
Storage pressure is 5.7MPa at 20°C. Maximum operating pressure is 12.4MPa at 50°C. The first figure describes the container as supplied; the second is the design ceiling on the high-temperature side.
Three start paths: electromagnetic start at DC24V / ≤1.5A, mechanical emergency start, and manual start. The modular design is intended for integration with existing fire detection and alarm architectures.
The container is 70L holding 42kg of CO2, with a stated discharge time of ≤60 seconds.
The stated operating range is 0°C to +50°C, which is the window to compare against ambient conditions in the protected room and the cylinder location.
Deployment is total flooding for enclosed spaces or local application for targeted discharge. CO2 is non-reactive and residue-free and dissipates quickly, so cleanup on equipment is minimal.
The product data states that CO2 is toxic to humans, and the system is for unmanned areas or requires safety measures in occupied spaces. Occupancy, egress and interlocks belong in the design decision, not in a footnote.
Everything below comes from the supplied product data for the 70L 5.7MPa CO2 gas fire suppression system. Treat it as the unit to size against, then confirm final quantities with the factory against your room data.
| Parameter | Value |
|---|---|
| Fire extinguishing agent container | 70L / 42kg |
| Storage pressure (20°C) | 5.7MPa |
| Maximum operating pressure (50°C) | 12.4MPa |
| Agent discharge time | ≤60s |
| Starting method | Electromagnetic start (DC24V / ≤1.5A), mechanical emergency start, manual start |
| Operating temperature range | 0°C ~ +50°C |
| Deployment | Total flooding (enclosed spaces) or local application (targeted discharge) |
| Suitable fires | Gas (where the supply can be cut off), liquid, meltable solids such as wax, solid surfaces, deep-seated materials such as fabric and paper, and electrical |
5.7MPa describes the stored condition at 20°C. 12.4MPa at 50°C is what downstream components must be planned for — check the room's summer ambient before fixing the pipework.
Electromagnetic release draws DC24V at ≤1.5A. That figure sizes the control output you need from the panel or loop interface.
Discharge completes in ≤60 seconds. Egress arrangements, warning devices and interlocks should assume a near-immediate release after actuation.
The stated operating range of 0°C to +50°C applies to the equipment. Compare it with the coldest and hottest conditions your installation will actually see.
CO2 is toxic to humans. The system is intended for unmanned areas, or for occupied spaces only with safety measures in place. Plan detection, alarm, delay and egress provisions around that statement before the system is specified into a manned room.
The protected space type drives more of the specification than the agent choice does. Use the scenarios below to connect a room type to the system facts that decide the design, then confirm the detail with the factory.
CO2 is residue-free and dissipates quickly, and the discharge time is ≤60 seconds.
Confirm the hall is normally unoccupied and that the DC24V / ≤1.5A release ties into the detection loop.
Electrical fires are within the stated suitable-fire list, and three starting methods are available.
Use electromagnetic start from the panel, and keep manual and mechanical emergency release reachable outside the door.
Deep-seated materials such as fabric and paper are covered, and the agent leaves no residue on records.
Total flooding needs a sound enclosure; check room tightness and keep the occupied-space safety plan current.
The equipment is rated for 0°C to +50°C, covering most plant-room conditions.
Match the room's ambient extremes to that window and plan the high side around 12.4MPa at 50°C.
Liquid fires are covered, and gas fires are covered where the supply can be cut off.
Verify that the fuel or gas supply can be shut off, since the agent's stated coverage depends on it.
Local application discharges directly at the targeted hazard rather than flooding the whole room.
Use local application where the risk is one machine or enclosure; use total flooding where the whole room is the hazard.
Take the room list from the project drawings, assign each space to one scenario above, and note which specification fact decides it. Rooms where nobody can confirm occupancy or fuel shut-off should be flagged before an agent is chosen — those two answers change the design more than the container size does.
Where a scope mixes room types, the same 70L 5.7MPa CO2 container can serve total flooding in one space and a local application in another, provided each hazard is reviewed on its own terms.
EPC submittals are usually held up by missing documents rather than missing hardware. Build the document list into the request so the response arrives against your requirements instead of a generic brochure set.
70L / 42kg agent, 5.7MPa storage at 20°C and 12.4MPa maximum operating at 50°C, stated in the format your reviewer expects.
Interface detail for the DC24V / ≤1.5A electromagnetic release, plus mechanical emergency and manual start provisions.
Arrangement information for the container, release and distribution so the installer can coordinate with other trades.
Handover material for the facility team covering normal condition, inspection points and the stated operating window.
State the checks you want witnessed or documented at the factory, and the format your review file requires.
Confirm packing method, marks and the export paperwork set your destination requires before the order is placed.
The document list above is the set to name explicitly in your enquiry. Requests are answered against the project scope, so include the standard or authority you are submitting to and the format the reviewer accepts — that avoids a second round of correspondence.
A structured request shortens the quotation cycle. Include the items below so the first reply can be a scoped, priced quotation rather than a clarification message.
Send the items on the left with your room data. Project enquiries, quantity requirements and documentation requests are all handled through the contact route, so one message covers the technical and commercial questions at the same time.

Engineered with 10L capacity, this system provides rapid fire control. Source from a reliable fm200 gas fire suppression system supplier for industrial safety.
View productthe supplied product is the 70l 5.7mpa co2 gas fire suppression system: a 70l agent container holding 42kg of co2, with a storage pressure of 5.7mpa at 20°c and a maximum operating pressure of 12.4mpa at 50°c.
5.7mpa at 20°c describes the container as supplied. 12.4mpa at 50°c is the highest operating pressure to plan for, which is why the ambient temperature of the protected room matters when the installation is laid out.
three start paths are stated: electromagnetic start at dc24v / ≤1.5a, mechanical emergency start, and manual start. the modular design is intended to integrate with existing fire detection and alarm systems.
the agent discharge time is ≤60 seconds and the operating temperature range is 0°c to +50°c.
the product data states that co2 is toxic to humans and that the system is for unmanned areas or requires safety measures in occupied spaces. occupancy, warning and egress provisions should be treated as part of the design decision.
