Industrial Humidification

Microcool high-pressure fog

Humidification with MicroCool high-pressure fog is suitable for large process areas or storage areas. The flexibility of the controls and the system allows it to be used for these applications for considerably less investment than “conventional” methods.

MicroCool fog nozzles each deliver 5.50 kg of water per hour in the form of billions of water droplets that quickly evaporate in the air. The standard design of a MicroCool humidification system is to evenly distribute the nozzles through the space to ensure that the control and delivery is even throughout the area.

Systems consist of a grid of nozzles through the building with a simple manifold connecting each one. Zones can be controlled through special sectioning controllers and valves to deliver the humidification only where it is needed.

Control systems are equally important in humidification systems as they need to respond quickly to the fog delivery and keep the humidification level as close to the setpoint as possible. MicroCool has invested time in researching the best controls possible to work with our systems and integrate with the pumps and RO units.

The pump units respond to changes in demand by increasing or decreasing speed, saving energy where necessary and reducing the water usage. We STRONGLY recommend the use of reverse osmosis water where possible as this eliminates dusting (calcium deposits) and significantly increases nozzle life.


When growers heat their greenhouses in the winter months, the resulting drop in humidity levels can seriously affect the crop production or quality. The MicroCool system helps the grower maintain the optimum levels equally through the growing area.

The MicroCool system operates in conjunction with all of the other control elements in the greenhouse to make sure that each component works in harmony to create the right environment.

Grids of nozzles positioned throughout the greenhouse ensure even and constant temperatures and humidity levels (unlike fan & pad systems). Anti-drip nozzles and careful design ensure that there are no drips or excess drain water that can damage crops. Nozzle lines in stainless steel or flexible lines make sure that installation is fast and easy.


Cold Stores

The control of humidity levels at extreme low temperatures presents unique difficulties that the MicroCool system is perfectly poised to address. Cold stores generally hold large quantities of vegetables and perishable goods which can deteriorate rapidly in low humidity conditions.

The chillers and coolers used in these applications “strip” the air of any water thus drastically reducing the humidity level in the cold store. This water deficit needs to be replaced to maintain the correct humidity levels in the cold store.

The amount of water required to raise the humidity level at these low temperatures is extremely small, therefore the MicroCool system must be carefully calculated to add just the right amount of humidity under varying conditions. Fork lift and personnel traffic can quickly change the level needing a fast response from the system.

MicroCool controllers and systems react very quickly to the humidity deficit and use different stages of nozzles to speed up the recovery process if required. Sectioning controllers placed on each cold store can react immediately to the signal giving a very fast reaction time.

Barrel Storage

When wine or alcohol spirits are placed in wooden barrels, the storage humidity level has a great effect on the “leakage” of vapour from the barrel. Often called the “Angels Share”, wine producers can suffer up to 18% loss from each barrel, which increases the alcohol level beyond tolerable levels.

In modern day above ground “caves”, the storage facilities find it much harder to maintain optimum humidity levels resulting in a big difference between the inside and outside of the wooden barrel. Vapours can then travel through the drier staves into the atmosphere. Wines in oak barrels need constant “topping off” over their storage and maturity to maintain the fine balance of alcohol content and taste.

MicroCool humidification systems in barrel rooms help maintain an optimum humidity level equalizing the levels between the inner and outer barrel. Vapour losses are controlled giving the winemaker an extra tool with which to perfect his craft.

The fine balance of temperature, humidity; outside and chilled air enable the wine maker to hone his expertise. MicroCool sensors monitor and maintain the humidity level to his preset demands. The use of a Reverse Osmosis system eliminates any water borne moulds or viruses collecting on the barrels during the process, also keeping the nozzles clean throughout many seasons.


Humidification levels in the Poultry industry are just as important as horticulture, industry and buildings. The correct humidity level in hatcheries helps in many different aspects of the process.

At the “egg” stage, too low humidity levels can affect the strength and density of the shell affecting birth rate and maturity. Once hatched an ideal humidity helps the chicks through the initial stages of growth before being moved to other facilities.

Most hatcheries consist of many different rooms and processes, each of a different size and requiring varying humidity levels. Sectioning controllers at each locations are controlled from external units or part of the climate control scheme. The sectioning controllers feature the MicroCool DCS (drain control system) which controls the drain process and reduces shock and vibration.
