Cold Storage

MeeFog Systems Optimize Storage with Precise Humidification Control

Humidifiers maintain optimum conditions for maximum storage and shelf life of the produce. Close attention to fruit and vegetable conditions will yield increased returns. MeeFog systems create high volumes of ultra-fine droplets that evaporate quickly and help to reduce deterioration due to water loss.


  • Improved keeping quality.
  • Minimize loss of weight and value.
  • Enhanced visual features.
  • Ultra-fine fog droplets – no wetting.

Water Pre-Treatment

Water Pre-Treatment

Basic water treatment, namely, a water softener is required for mineral removal. Based on dust-free requirements for the space additional components including reverse osmosis with automated membrane flushing and pre-treatment filtration can be added. 

MeeFog Pump

MeeFog Pump

The high-pressure pump maintains 1000 psi water pressure in order to atomize the water into tiny droplets that can evaporate overhead. The pump rack has a VFD with panel-mounted controller that maintains pressure when zone valves open and close.

Zone Valve Panel

Zone Valve Panel

The MeeFog Zone Valve Panel provides control for up to five fogging zones. It can use an on-board humidity sensor or signal from other controllers to actuate ball valves that are slow acting to eliminate water hammer.

Swirl Jet Nozzles

Swirl Jet Nozzles

The MeeFog Swirl Jet nozzles are stainless steel with a .006” orifice and output 7 lbs. per hour of fog. Fog nozzles mounted on stainless steel tubing can be spaced one per 200 square feet or denser for areas with open bay doors or in need of higher humidity.

System Overview

Nozzle Comparison

At an operating pressure of 2000 psi, the resulting average droplet size is roughly one tenth the diameter of a single strand of human hair.

MeeFog System Benefits

  • Compressor not required.
  • Quiet operation.
  • Reduces topping.
  • Uniform humidity distribution.
  • Precise control.
  • Ultra-fine fog droplets – no wetting.
  • Flexible and easy to retrofit.

Droplet Comparison

Small droplets have a larger surface to volume ratio compared to larger droplets. This allows them to evaporate much more rapidly than larger droplets.
