Fike Micromist® Self Contained Water Mist Fire Suppression

Powerful water mist fire protection for turbines, generators, and machinery spaces that do not have a reliable water supply. Fike Micromist packages high pressure water mist into a compact, self contained skid that SSI designs, installs, and services across Pennsylvania, New Jersey, New York, Delaware, and Maryland.

Micromist Overview, In One Look

  • Self contained system with integrated water tank and nitrogen cylinders, no connection to building water needed.
  • High pressure water mist generates extremely fine droplets that cool, inert, and wet the fire.
  • Ideal for machinery spaces such as gas turbines, diesel generators, and industrial equipment enclosures.
  • Minimal water use compared to sprinklers, which supports faster cleanup and reduced collateral damage.
  • Engineered and serviced by SSI for facilities across the Mid Atlantic and Northeast.

What Is Fike Micromist

Fike Micromist is a pre engineered, self contained water mist fire suppression system. Instead of relying on a building fire pump or city water main, Micromist uses a dedicated water storage tank and nitrogen cylinders mounted together on a skid.

During a discharge, nitrogen pressurizes the water tank and drives water through specially designed nozzles that atomize it into a fine mist. This mist behaves very differently than a standard sprinkler spray.

  • Many more droplets than a sprinkler, which increases the surface area of water in contact with the fire.
  • Fast heat absorption as droplets turn to steam at the flame front.
  • Localized oxygen reduction as steam expands at the fire and helps interrupt combustion.

Micromist is part of a broader family of water mist solutions that follow the principles in NFPA 750, Standard on Water Mist Fire Protection Systems, which defines water mist as having a droplet size below 1000 microns at the nozzle.

When Micromist Is The Right Choice

Micromist is designed for hazards where you need powerful suppression and cooling, but do not have or do not want to depend on a building water supply.

  • Remote generator buildings without domestic water or fire pumps.
  • Gas turbine enclosures that need intense cooling on hot casings and exhaust components.
  • Diesel generator rooms in hospitals, data centers, and industrial plants.
  • Machinery spaces where a traditional sprinkler system would cause excessive water damage or cannot be installed.
  • Compact retrofit projects where space for pumps and tanks is limited.

For facilities with larger coverage needs or where you want a pump based system that connects to domestic water, see our Fike DuraQuench Pro water mist page.

Key Benefits Of Fike Micromist

Self Contained Fire Protection

Micromist is a fully packaged system. Water storage, nitrogen cylinders, controls, and discharge nozzles are engineered to work together. That means:

  • No reliance on city water or separate fire pumps.
  • Predictable discharge performance based on known tank and nozzle data.
  • Installation flexibility in remote or standalone structures.

High Efficiency Cooling With Less Water

Water mist uses far less water than traditional sprinklers for the same protected volume. The fine mist absorbs heat quickly and cools surfaces, which helps limit distortion and damage on turbines and engines.

For a deeper look at water mist principles, see this NFPA water mist overview and the water mist section in the fire sprinkler system article.

Safer Alternative To CO2 In Many Machinery Spaces

In some applications, CO2 can be effective but brings additional risk in areas that may be entered by personnel. Micromist provides powerful cooling and suppression using water, which can be a safer choice for certain machinery spaces when designed correctly.

For comparison, you can review our fire suppression solutions overview, which includes clean agents, inert gas, CO2, and water based options.

How Micromist Extinguishes Fires

Micromist combines multiple suppression mechanisms that are described in NFPA 750 and other water mist guidance documents.

  1. Cooling The mist absorbs heat from flames and hot surfaces. As droplets turn into steam, they remove significant energy from the fire, which reduces temperature below the point where combustion can continue.
  2. Oxygen Reduction At The Flame Steam produced at the fire front expands and helps locally dilute oxygen and fuel vapors, which interrupts the combustion process.
  3. Surface Wetting Droplets that do not instantly vaporize help wet surfaces and residual fuel, which reduces the risk of re ignition once flames are knocked down.

These combined effects make water mist particularly effective for machinery spaces, turbines, and generators where both cooling and oxygen reduction are important.

Water mist fire protection concepts are also discussed in external resources such as NFPA 750 explanatory material and water mist standards summaries like global water mist standards overviews.

Typical Micromist Applications

Gas Turbines And Generator Enclosures

Micromist is well suited to turbine and generator housings where fire risk comes from fuel, oil, and hot surfaces. The system can be configured to provide total flooding within the enclosure or local application at the most critical areas.

Remote And Standalone Buildings

Where a building does not have a reliable water supply or fire pump, Micromist offers protection without adding major infrastructure. Examples include remote telecom shelters, generator sheds, and small industrial outbuildings.

Industrial Machinery And Process Equipment

Micromist can be engineered for certain machinery spaces where localized cooling and limited water usage are priorities. SSI evaluates each hazard against applicable standards and manufacturer test data before recommending this technology.

For broader special hazard design guidance, review our Design Considerations for Special Hazards article.

Micromist System Components And Technical Data

Fike Micromist systems are offered in multiple skid configurations. Common features include:

  • Water storage tank sized for the protected compartment and design discharge duration.
  • Nitrogen cylinders that provide the driving pressure for the water.
  • High pressure distribution piping and Micromist nozzles sized to match hazard and coverage requirements.
  • Release controls that can be integrated with detection systems such as Fike Cheetah Xi where appropriate.
