ALF-NANO
Compact spark detection & extinguishing system
Local protection for production lines with a risk of sparks, embers or hot spots. EWS ALF-NANO detects and extinguishes sparks at localized risk points, with up to two protection areas, pre-configured system logic and safety event logging

Local protection for combustible-material handling
Spot the spark. Protect the line.
Detects and extinguishes sparks at localized fire and explosion risk points in production lines.
Designed to reduce fire risk, protect machinery and limit production line downtime with a cost-conscious investment.

Built for straightforward local protection
Part of the Electronic Wood Systems ALF family, ALF-NANO follows ALF-9000 design principles and is optimized for small applications. Its focus is fast spark detection, reliable extinguishing and simple deployment at the plant.
Compact system
Designed for small applications and local protection of individual machines or limited areas.
Plug-and-play integration
Direct connection of detectors, extinguishing valves and sensors; no complex manual configuration required.
Fast commissioning
Pre-configured operation reduces installation effort and startup time.
Internal supervision
Automatic monitoring of detectors, valves and wiring supports system readiness.
Extinguishing monitoring
Monitors water flow, leakage, water supply status and connected external safety devices.
Event logging
Stores safety-related events for later inspection and maintenance, supporting operational traceability.
Suitable installation points
- Individual machines, conveyors, small work areas, transfer points and material conveying lines
- Early spark detection and extinguishing to help prevent fire spread, dust fires and production line stoppages.
- Retrofit projects and space-constrained locations
- Add safety protection without major modifications to the existing line structure.
