Fogging - The Science of Evaporative Cooling + Humidification

For centuries, the principle of evaporative cooling has been used to combat heat and add humidity. MicroCool melds this age-old principle with the very latest technology to create advanced engineering solutions for controlled humidification in a variety of applications.

How a MicroCool Fogging System Works

How Fogging Works

Fogging Technology. There is a difference.

When comparing MicroCool fogging systems to other methods of process cooling and humidification (electrode and steam humidification), it soon becomes obvious that MicroCool technology has many advantages in cost, distribution and operation.

And buyer beware, as the market is awash with fogging/misting systems marketed by companies who make exaggerated claims and promises using low-cost, imported equipment that is primarily designed for domestic outdoor cooling situations.

MicroCool fogging solutions (whether IBEX or FOCUS), on the other hand, are designed for demanding industrial applications that utilize the latest in electronic controls and pump technologies. And, we provide the technical specifications to back up our statements.

Misting Nozzles

Patented Nozzles

MicroCool’s new-generation, American-made nozzles are designed to last longer and provide more consistent delivery than lesser, imported components.

  • Unprecedented versatility — Instead of having every nozzle positioned identically, the patented rotatable collar enables mist to be pointed in any direction. This flexibility in positioning provides even humidity levels throughout a location.
  • FOCUS nozzle systems — Each nozzle can be positioned and controlled separately to deliver fog wherever it's required
  • Integrated filter — Protects nozzle from contamination in the line
  • High-volume drain valve — Nozzle line empties on shutdown to eliminate bacteria from forming in stagnant water
  • Drip-free design — The nozzle closes after operation to eliminate any dripping
  • Made in the USA — Equipment is assembled in our California factory using local parts and materials where available
Ibex Pump


Our exclusive powerful IBEX and FOCUS pumps are designed to deliver economical, long-life performance.

  • Variable-speed drive — Automatically adjusts pump speed to water flow and number of nozzles, reducing electrical usage and pump wear
  • Compact, quiet — less intrusive, can be mounted closer to production areas, eliminating long runs of pipework
  • Saves energy, money — Reduces electricity use by more than 60%
  • Extended pump life — Less wear and tear on the pump
  • Inlet pressure switch — Prevents the system running dry and damaging the pump
  • Pressure transducer — Maintains optimal system pressure for MicroCool nozzles
  • Remote operation — Ties into external sensors, BMS systems (analog) and climate control systems
  • Drain valve — using a PLC controller, the valve opens just enough to release the pressure, saving valuable water usage
  • Built to 508 UL standard — Safety, reliability
  • Powder coated steel frame — Strong, long-lasting durability
  • 1-year warranty — Backed by responsive MicroCool service
Stainless Steel Nozzles
Stainless Steel Lines

Simply put, MicroCool misting lines look better, perform better and last longer.

  • Stainless steel lines and fittings – No corrosion
  • 3/8" diameter — More rigidity and longer nozzle runs.
  • Innovative rotating collar — The ROC collar is a MicroCool exclusive, allows each nozzle to be rotated through 180° independently
  • Corrosion proof, weld-free — Nozzle attachment prevents warping
  • Made in the USA — Dependable quality
  • Strength — Our stainless steel lines are tested to 3,000 psi to ensure integrity
