NATURA™-Micro Inert Gas Fire Suppression System

Self-Contained Fire Protection for Cabinets, Enclosures, and Critical Equipment

The NATURA™-Micro Inert Gas Fire Suppression System is a self-contained fire detection and suppression solution designed to protect cabinets, enclosures, and localized hazards. By combining early detection with clean IG-100 inert gas suppression in a compact, integrated unit, NATURA™-Micro enables rapid response directly at the source of a fire.

As part of the KiddeFenwal NATURA™ portfolio, NATURA™-Micro extends inert gas protection to smaller, high-value environments—helping prevent incidents from escalating while minimizing downtime, damage, and disruption.

Key Advantages
  • Self-Contained Detection and Suppression
    Integrated detection and IG-100 inert gas suppression in a single unit simplifies installation and accelerates response time
  • Early Fire Detection at the Source
    Detects fire conditions within cabinets and enclosures before escalation, enabling fast, targeted suppression
  • Clean, Residue-Free Protection
    Non-particulate inert gas discharge protects sensitive electronics without leaving residue or causing corrosion
  • Minimized Downtime and Business Impact
    Suppresses fires in the incipient stage, supporting operational continuity and faster system recovery
  • Simple Installation and Operation
    No special software or commissioning tools required, reducing setup complexity and deployment time
  • Modular and Scalable Design
    Up to 8 units can be connected toget

Applications

NATURA™-Micro is designed for localized fire protection in enclosed environments where sensitive equipment and continuous operation are critical, including:

  • Electrical and control cabinets
  • Server racks and data enclosures
  • Telecommunications equipment
  • Industrial control panels
  • High-value or mission-critical equipment
Applications for NATURA™-Micro Inert Gas Fire Suppression System
System Architecture

System Overview

NATURA™-Micro integrates detection, activation, and suppression into a compact system designed for direct, localized protection.

Suppression Method

  • Utilizes IG-100 inert gas to reduce oxygen concentration and extinguish fire
  • Non-particulate discharge preserves equipment and eliminates cleanup
  • Rapid suppression at the source of ignition

Cool Gas Generator (CGG) Technology

  • Generates low-pressure nitrogen at ambient temperature upon activation
  • Disperses clean gas directly into the protected enclosure
  • Provides reliable, maintenance-friendly suppression with a 10-year life time

System Integration

  • Includes activation module, internal power supply, and battery backup
  • Provides three relays (pre-alarm, alarm, and fault) or two relays (alarm and fault) for system monitoring, depending on system type chosen
  • Designed for standalone operation or integration into broader safety systems

Detection Options

NATURA™-Micro is available in two detection configurations to meet different application requirements:

NATURA™-Micro ASP (Aspirating Smoke Protection)
Designed for early warning detection, ASP continuously samples air using multiple optical sensors to identify smoke at the earliest stages.

  • Three optical smoke sensors for continuous monitoring
  • Ideal for high-sensitivity environments and critical equipment
  • Enables rapid detection before visible fire develops

NATURA™-Micro LHS (Linear Heat Suppression)
LHS provides reliable heat-based detection for applications where robust, straightforward detection is required.

  • Linear heat detection cable for direct temperature sensing
  • Ideal for harsher or less controlled environments
  • Simplified installation and dependable operation

Available Models

NATURA™-Micro systems are available in multiple sizes to match enclosure volume and protection requirements:

ASP Models

  • ASP 750 – up to 44.1 ft³ (1.25 m³)
  • ASP 1500 – up to 88.3 ft³ (2.5 m³)
  • ASP 2250 – up to 132.4 ft³ (3.75 m³)

LHS Models

  • LHS 750 – up to 44.1 ft³ (1.25 m³)
  • LHS 1500 – up to 88.3 ft³ (2.5 m³)
  • LHS 2250 – up to 132.4 ft³ (3.75 m³)

Up to eight units can be connected to protect larger combined volumes up to approximately 1,059 ft³ (30 m³)
