FK-5-1-12 Fire Suppression Cylinders: Capacities, Pressure Ratings and Technical Specifications

Selecting the correct cylinder is an important part of designing an FK-5-1-12 fire suppression system. Engineers must consider the required agent quantity, cylinder capacity, pressure rating, cylinder construction, valve compatibility, and the technical requirements of the complete system.

FK-5-1-12 is a clean extinguishing agent commonly associated with the Novec 1230 trade name. It is used in engineered fire suppression systems protecting applications such as data centers, server rooms, electrical rooms, telecommunications facilities, control rooms, and other suitable critical environments.

An FK-5-1-12 fire suppression cylinder should not be selected by capacity alone. Its pressure rating, permitted filling conditions, compatibility with the selected system, and the manufacturer's technical documentation must all be reviewed.

This guide explains the main FK-5-1-12 cylinder specifications, available capacity and pressure configurations listed by AGNITAR, and the checks engineers should complete before selecting a cylinder for a clean agent fire suppression system.

1. What Is an FK-5-1-12 Fire Suppression Cylinder?

An FK-5-1-12 fire suppression cylinder is a storage vessel used as part of an engineered clean agent system. The cylinder stores the extinguishing agent under the conditions specified for the selected system and connects to the discharge arrangement through compatible valves and associated components.

The cylinder is one part of the complete installation. Its selection must be coordinated with the calculated agent requirement, the approved system configuration, piping network, discharge nozzles, and applicable design requirements.

FK-5-1-12 cylinders may be described in product searches using several related terms, including:

• FK-5-1-12 cylinder
• FK-5-1-12 fire suppression cylinder
• Novec 1230 cylinder
• Novec 1230 clean agent cylinder
• Clean agent fire suppression cylinder
• FK-5-1-12 cylinder specifications

These phrases refer to closely related search topics, but the exact cylinder specification must always be confirmed from the relevant product documentation.

2. FK-5-1-12 Cylinder Capacities and Available Configurations

Cylinder capacity is an important selection parameter, but it should not be confused with the quantity of extinguishing agent required for a protected enclosure.

The required agent quantity is determined through the approved system design method. The cylinder configuration is then selected to accommodate that quantity within the relevant filling conditions and product specifications.

AGNITAR Cylinder Capacity and Pressure Specifications

AGNITAR lists the following cylinder configurations for FM-200 (HFC-227ea) and FK-5-1-12 (Novec 1230) fire suppression applications.

These configurations are based on the available AGNITAR cylinder product specifications. Engineers should confirm the current product documentation and the exact configuration required for their project before specifying a cylinder.

The capacity options listed above do not mean that every cylinder size is available for every pressure configuration. The cylinder's documented maximum working pressure and the system's nominal pressure configuration must be checked separately.

For current product information, review the AGNITAR FM-200 and FK-5-1-12 fire suppression cylinder range.

3. Understanding 25 Bar and 42 Bar Cylinder Pressure Ratings

Pressure rating is an important part of clean agent cylinder selection. However, the pressure rating of a cylinder must not be interpreted as a complete description of system performance.

AGNITAR lists cylinder configurations with maximum working pressure ratings of 25 bar and 42 bar. The relevant pressure configuration must be selected according to the approved system design and the specifications of the cylinders and components used.

25 Bar FK-5-1-12 Cylinder Configurations

A 25 bar cylinder configuration must be selected according to the approved system requirements and the documented capabilities of the cylinder, valve, and associated components.

When specifying a 25 bar FK-5-1-12 cylinder, engineers should verify:

• The cylinder's maximum working pressure
• The permitted agent filling conditions
• The compatible valve and discharge arrangement
• The cylinder capacity required by the design
• The approved system configuration and technical documentation

AGNITAR lists a 267 L TPED-certified, Pi-marked welded cylinder with a maximum working pressure of 25 bar in its combined FM-200 and FK-5-1-12 cylinder range.

42 Bar FK-5-1-12 Cylinder Configurations

AGNITAR's listed 42 bar maximum-working-pressure cylinder options include welded and seamless cylinder types.

The documented welded cylinder capacities are 16, 26, 45, 83, 120, 149 and 180 L. The listed seamless cylinder capacities are 13.4 and 27 L.

A cylinder rated for a maximum working pressure of 42 bar may be suitable for a system configuration specified by the manufacturer, but the actual system pressure arrangement and component compatibility must be confirmed from the relevant documentation.

Does a Higher Pressure Rating Automatically Mean Better Performance?

No. A higher cylinder pressure rating does not, by itself, establish that a system will discharge faster or perform better.

System performance depends on the complete engineered arrangement, including the agent quantity, cylinder configuration, valves, piping network, nozzles, hydraulic calculation, and applicable design criteria.

Pressure rating should therefore be treated as one selection parameter rather than a standalone performance indicator.

For a broader comparison, see the 25 bar vs. 42 bar clean agent fire suppression systems guide.

4. Cylinder Capacity vs. Agent Fill Quantity

One of the most important distinctions in FK-5-1-12 cylinder selection is the difference between cylinder capacity and agent fill quantity.

Cylinder capacity describes the vessel's internal volume. Agent fill quantity describes the amount of extinguishing agent stored in the cylinder under the specified filling conditions.

These values are related, but they are not interchangeable.

The required agent quantity for the protected enclosure must be established through the approved design calculation. Engineers then determine the cylinder arrangement using the permitted fill quantity, available cylinder specifications, and the requirements of the selected system.

A larger cylinder does not automatically mean that the design contains the correct quantity of agent. Likewise, selecting a cylinder based only on its nominal capacity does not verify that the overall system meets the design requirements.

What Engineers Should Verify

Before approving a cylinder arrangement, check:

1. The required agent quantity from the approved system calculation.
2. The cylinder capacity and permitted fill conditions.
3. The number of cylinders required by the selected configuration.
4. The applicable cylinder pressure rating.
5. The compatibility of valves, hoses, manifolds, and other components.
6. The consistency of the cylinder schedule with the hydraulic calculation and system drawings.

These checks help ensure that cylinder selection remains consistent with the complete fire suppression system design.

5. Welded vs. Seamless FK-5-1-12 Cylinders

Cylinder construction is another specification that should be reviewed when evaluating a clean agent cylinder.

AGNITAR's listed product range includes both welded and seamless cylinders. The available capacities and pressure ratings differ by cylinder type, so engineers should consult the corresponding technical documentation rather than assuming that the two constructions have identical specifications.

When comparing welded and seamless cylinder options, review:

• Documented capacity and dimensions
• Maximum working pressure
• Permitted filling conditions
• Relevant conformity documentation
• Valve connection and compatibility
• Installation requirements
• Availability for the required system configuration

The selection should be based on the documented product characteristics and the requirements of the approved system design. Cylinder construction alone should not be used as a substitute for checking pressure rating, filling conditions, or system compatibility.

6. TPED Certification and Pi Marking

Technical conformity documentation is an important consideration when sourcing fire suppression cylinders for projects subject to applicable European pressure equipment requirements.

AGNITAR lists TPED-certified, Pi-marked cylinders in its relevant cylinder product range. Buyers and engineers should verify the documents that apply to the specific cylinder model and intended application.

The technical review may include:

• Cylinder identification and traceability
• Applicable conformity documentation
• Pressure rating and capacity
• Manufacturer information
• Relevant marking and inspection records
• Compatibility with the selected fire suppression system

Certification and marking claims should be checked against the actual product documentation. The presence of a particular marking on a cylinder should not be interpreted as evidence that every component or the complete suppression system has the same approval.

7. Cylinder Valves and Component Compatibility

An FK-5-1-12 cylinder must be compatible with the valve and discharge arrangement specified for the system.

The cylinder, valve, actuator, pressure gauge, discharge hose, manifold, and other relevant components form part of the engineered installation. Their selection should be checked against the manufacturer's documented configuration and pressure requirements.

Engineers should confirm:

• Valve model and connection details
• Applicable pressure rating
• Compatibility with the cylinder and extinguishing agent
• Actuation requirements
• Relevant accessories and monitoring devices
• The approved discharge arrangement

A valve should not be selected based solely on a similar nominal pressure rating or connection size. Compatibility must be established for the actual cylinder and system configuration.

See the AGNITAR fire suppression cylinder and component range for further product information.

8. How to Select the Correct FK-5-1-12 Cylinder

The correct cylinder selection process begins with the design requirement rather than a preferred cylinder size.

Step 1: Establish the Required Agent Quantity

Determine the required FK-5-1-12 quantity using the applicable standard and the approved design method for the selected system.

Step 2: Identify Compatible Cylinder Options

Review the cylinder capacities and pressure configurations documented for the selected system. Do not assume that every capacity is available at every pressure rating.

Step 3: Check Permitted Fill Conditions

Confirm that the required agent quantity can be accommodated within the cylinder's permitted filling conditions and the manufacturer's specifications.

Step 4: Verify Valve and Component Compatibility

Check the cylinder valve, actuation arrangement, hoses, manifold, and other relevant components against the approved configuration.

Step 5: Coordinate the Cylinder Schedule with the Hydraulic Calculation

The final cylinder arrangement must match the approved hydraulic calculation and system drawings. If the configuration changes, the calculation should be reviewed and revised where required.

Step 6: Confirm Documentation Before Procurement

Verify the product datasheet, conformity documentation, cylinder identification, pressure rating, capacity, and other information required by the project specification.

Following these steps helps engineers and procurement teams evaluate FK-5-1-12 cylinder options without relying on capacity or pressure rating alone.

9. FK-5-1-12 Cylinder Selection Checklist
