Maintain a Healthy Indoor Environment with an Energy Efficient
Adiabatic Humidification System

While most people consider proper humidification a matter of comfort, it also plays a key factor in maintaining health. The human respiratory system requires and creates warm, saturated air in the lungs and airways. Low humidity environments put a strain on this system and inhibit proper lung function. Additionally, studies have shown that maintaining RH levels above 40% inhibit the spread and viability of airborne virus. Low RH levels can lead to slow recoveries and even hospital acquired infections.

Recently, ASHRAE Standard 170-2013 Addendum m approved the use of energy efficient high-pressure fogging systems for hospital humidification.

The fogging process is very simple and straightforward. First the water supply is rigorously purified and sterilized, then the water is pressurized to 1,000 psi via the MeeFog pump skid. The water is then fed to MeeFog nozzles, which inject pure water fog into the air stream. This allows for accurate control of humidity to a specified RH%.

MeeFog humidification includes the necessary reverse osmosis water treatment systems, and valves for recirculating water in the pressure lines back to a UV treated holding tank.

To find out more about how the system can work for you, contact one of our sales engineers.

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.

Theory of Operation

Droplet Comparison Chart

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