At KL2B, we have developed four models of RIA systems (rigid/semi-rigid fire reels) with foam generation capabilities, designed to provide a first line of defense against fires and are especially useful in industrial, maritime, and highly demanding environmental environments. Instead of directly relying on monitors or large cannons, these devices are positioned as an immediate, simple, and effective resource, with all technical and regulatory guarantees.

What makes them attractive is their combination of speed, operability, and resource savings:

When a fire starts, every second counts. Since these reels are always loaded and ready, response is practically instantaneous, without the need to set up additional equipment or wait for the main operations to be organized. This drastically reduces downtime until larger systems or specialized personnel can respond.

But in addition to speed, there is an element of operational simplicity: the switch from using pure water to foam generation is achieved without manual complications or additional interventions. With a single maneuver, it is possible to increase effectiveness against more aggressive fires. This avoids the operator having to manipulate mixers or auxiliary pumps under pressure, which adds risk and complexity.

Another key aspect: water efficiency. Foam covers the combustion surface more evenly, fills pores, reduces water rebound, and reduces the total amount needed to extinguish. In many cases, this translates into water savings and less collateral impact on sensitive facilities.

Furthermore, these systems are designed to withstand aggressive environments. Made of stainless steel with electrolytic treatments and anti-corrosion finishes, they can be deployed in maritime, chemical, or industrial environments with high humidity and salinity without losing functionality. This resistance gives them real longevity, beyond their theoretical performance.

And no less important: they act as an ideal complement against flammable liquids. By generating foam, they create a sealing layer that limits the release of vapors and acts as a barrier between the fuel and oxygen, something that water alone cannot do. In chemical warehouses or in Hazard B zones, this capacity is crucial.

However, these systems are not intended to replace high-capacity monitors, cannons, or automatic foam systems. Their role is clear: to provide a robust and reliable first line of defense, allowing fires to be contained or fought in their initial stages, while waiting for more powerful systems to arrive.

Technical aspects and available models

Applicable regulations

The RIAs presented have been designed and tested taking into account the European regulations applicable to fixed hose systems. The EN 671 — Fixed firefighting systems: Hose systems standard is structured in several parts: EN 671-1, which specifically addresses semi-rigid hose reels; EN 671-2, which covers lay-flat hose systems; and EN 671-3, which establishes maintenance recommendations for hose reels and systems.

Furthermore, the semi-rigid hoses used in these devices must comply with the requirements and tests specified in EN 694.

At the national level, France has the NF S 62-201 standard, which defines practical rules for the design, installation, acceptance, and maintenance of Armed Fire Extinguishers (RIAs) and complements European requirements for projects and environments where they are required.

Compliance with these standards ensures not only technical compliance, but also acceptance in regulated markets and the traceability and records necessary for inspection and maintenance. CEN-CENELEC

The Four Models

Each of the four developed models is tailored to specific scenarios with variations in lance, rotation, mounting type, and features:

• Model KL-100019: RIA with an integrated foam production device, designed for situations where foam capacity is the primary requirement without the need for external accessories.

• Model KL-100021: Rotating and pivoting reel with an Attack 100 Pro D200 lance, ideal for applications requiring rotation and greater directional flexibility.

• Model KL-100022: Similar to the previous model, but with a 45° rotating lance, similar to the Attack 100 Pro A210, designed for areas with obstacles or nonlinear geometries.

• Model KL-100023: Variant with Attack 100 Pro A210 SUP lance, combined with DN 25 hose, optimized for higher pressure, durability, and coverage requirements.

The materials, treatments, and hydraulic calculations have been sized to offer reliable performance even under demanding conditions: common nominal pressures up to ~1.2 MPa, adequate flow rates, corrosion resistance, and robust turning mechanisms.

Recommended Applications

These systems are especially suitable for:

• Shipping companies, offshore platforms, and ports, where immediate protection against spills and small fires is required.

• Chemical and oil industries, where flammable liquids are present and foam capacity is a major plus.

• Airports, hangars, and technical areas, where an incipient fire must be attacked before it spreads.

• Critical infrastructure, military bases, or remote facilities, where reliable and autonomous equipment is vital.

Maintenance and Operational Recommendations

To ensure these systems are always operational, it is essential to follow a rigorous maintenance program:

1. Periodic visual inspection: verify structural integrity, free rotation of the reel, and absence of corrosion or deformation.

2. Annual functional tests: deploy the hose, open the valve, and check flow, pressure, and nozzle operation under real-world conditions.

3. Pressure testing (every 5 years or according to applicable regulations): Ensure that the unit withstands its maximum design pressure without leaks or deformations.

4. Internal cleaning of the foam device and lance to prevent buildup or blockage due to concentrate residue.

5. Documented records of all tests, as required by maintenance standards (e.g., EN 671-3 for maintenance of fixed systems).
