Universities & K-12

Central Humidifier Supplies Diverse Humidity Loads

Universities require the ability to supply proper levels of humidity to a wide range of climate zones. In a University setting labs require the most load in order to exhaust all of the air, classrooms and common areas will have separate requirements.

MeeFog uses a central pumping unit that supplies multiple air handlers and is an energy efficient solution. Each rack includes a programmable logic controller (PLC) which allows the system to operate safely in automatic mode using the building control system.

Unlike steam systems, there are no calcification issues, no elements to burn out, no floats to get fouled, and no bubble indicators. Fog system maintenance requires only oil changes and filter checks. Meefog humidification systems use substantially less energy than other humidification technologies, including compressed air, ultrasonic, and especially steam systems.


  • Reduced energy consumption.
  • Lower maintenance costs.

To find out more about how the system can work for you, contact a MeeFog sales engineer.

Reverse Osmosis Water Purification

Reverse Osmosis Water Purification

City water is treated using the Reverse Osmosis water treatment rack. This purifies the water, removing minerals, particulate, and microorganisms. Systems include automated membrane flushing, pre-treatment filtration, and UV Re-Circulation.

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 into the air stream. The pump rack has a VFD with panel-mounted controller that maintains pressure when staging valves open and close.

Staging Valves

Staging Valves

The valve panel allows precise control over how much humidification is injected into the air stream based on a signal from the BMS. It is possible to control the humidification level in the space to plus or minus 1% RH.

Nozzle Manifolds

Nozzle Manifolds

Fog nozzles are mounted on stainless steel tubing inside the air handler. These nozzles produce droplets in the 10-micron range. These precision nozzles are manufactured and tested in Mee Industries' own facility.

Mist Eliminator

Mist Eliminator

The mist eliminator removes water droplets larger than 5 microns. The filter pads can come off their stainless steel frames and can be washed or replaced easily.

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

  • Evenly distributed humidification.
  • Increased reliability.
  • Reduced energy costs.
  • Does not require compressed air or steam.
  • Reduces electrostatic shock.
  • Low energy consumption.
  • Precise humidity level control.

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.
