KiddeFenwal Advanced Delivery System (ADS™): Advanced Clean Agent Fire Suppression

Greater flow rates. Extended coverage. Reliable fire protection.

The KiddeFenwal Delivery System (ADS™) delivers enhanced clean agent fire suppression performance, offering greater design flexibility, improved agent distribution and efficient protection for larger, more complex hazard areas.

Designed to optimise the performance of conventional 360 psi (25 bar) and 500 psi (35 bar) clean agent systems, ADS™ uses a nitrogen driver to propel the suppression agent through the piping network.

Featuring patented piston-flow technology, the ADS™ achieves agent mass flow rates up to 2.5–3 times greater than conventional clean agent systems. This advanced technology enables longer pipe runs, more complex piping configurations and smaller pipe diameters, providing greater flexibility when protecting large or challenging environments.

Engineered for Performance and Reliability

Clean agent is stored in welded steel cylinders compliant with ISO 9809-2 and certified to DOT requirements. System activation and agent discharge are controlled through a pressure-regulating valve, with safety burst discs providing additional protection.

A range of cylinder sizes is available to accommodate different agent quantities and installation requirements, helping maximise available floor space. Cylinder-valve assemblies are supplied with anti-recoil and safety transport caps to minimise the risk of accidental discharge during handling and transportation.

Flexible Multi-Zone Fire Protection

The ADS™ can protect multiple hazard areas using a single central bank of cylinders, providing an efficient and flexible solution for facilities with multiple protected spaces.

In multi-zone applications, selector valves direct the suppression agent to the specific area where a fire has been detected. These valves are pneumatically operated using regulated pressure, with a nitrogen pilot cylinder providing the pressure required for activation.

This configuration allows a centralised suppression system to protect multiple hazards while optimising cylinder storage and system infrastructure.

Precision-Engineered Agent Distribution

The ADS™ incorporates specially designed discharge nozzles available in 180° and 360° configurations, suitable for upright or pendant installation.

Nozzle orifice sizes and system configurations are calculated using KiddeFenwals’ Flow Calculation Software Suite (version 4.0 or later), ensuring accurate agent distribution and system performance.

The software calculates critical design parameters, including pressure drops, pipe diameters, nozzle orifice sizes and vent area requirements, based on:

• Clean agent selection
• Cylinder size
• Nozzle configuration (180° or 360°)
• Single-zone or multi-zone arrangements using two-way selector valves

This precision-engineered approach supports effective system design across a wide range of applications.

Rapid Fire Suppression. Minimal Business Disruption.

When activated, the ADS™ rapidly discharges clean agent into the protected area, suppressing fire before it can escalate and cause extensive damage.

Unlike traditional suppression methods that may leave residue, clean agents provide effective fire protection without the need for extensive post-discharge clean-up.

Following a discharge, appropriate ventilation and safety clearance procedures allow facilities to return to normal operations, helping minimise repair costs, equipment damage and business downtime.

For facilities where operational continuity and asset protection are critical, ADS™ provides an efficient and reliable fire suppression solution.

Key Benefits of the KiddeFenwal ADS™

• Enhanced agent delivery: Mass flow rates up to 2.5–3 times greater than conventional clean agent systems.
• Extended protection coverage: Longer piping distances and flexible configurations support larger, more complex hazard areas.
• Optimised installation costs: Smaller pipe diameters can reduce material and installation requirements.
• Efficient agent storage: Higher cylinder fill capacities help optimise available floor space.
• Flexible multi-zone protection: A single cylinder bank can protect multiple hazard areas.
• Clean, residue-free suppression: Helps protect sensitive equipment and reduces post-discharge clean-up.
• Suitable for occupied spaces: Clean agent systems can be designed for use in normally occupied areas, subject to applicable safety standards and exposure limits.
• Reduced business interruption: Rapid suppression helps minimise fire damage, recovery costs and operational downtime.
