Preface
45% of all beautiful crops that grow on our fields ends up wasted. This not only puts a heavy
burden on our environment, but is also unacceptable in a world with a growing population and
so many mouths to feed.
Dry Misting is a technology that spreads tiny drops of water in the air, creating a thin layer of
mist. As the mist evaporates, the humidity rises and the temperature drops naturally. When
applied on fresh products, Dry Misting results in retaining freshness, colour and nutrients.
Extending the shelf life of these products up to twice as long and hereby reducing food waste.
At Contronics, we are on a mission is to reduce food waste by applying Dry Misting throughout
the entire fresh food supply chain.
Thank you for your purchase and joining us on this mission!

2.2.Description
The function of the humidifier is to generate and transport humidified air. This is done as
follows:
1.Water is transported into an internal water reservoir. Excess water is discharged.
2.Air is sucked into the humidifier by a fan. The air passes through a filter to remove
any pollution.
3.High-frequency vibrations (1.7 MHz) are generated by transducers at the bottom of
the water reservoir.
4.Water droplets (1 – 3 µ) are ejected above the water surface.
5.Water droplets mix with the air.
6.Humidified air is transported out of the humidifier into the connected distribution
system.

2.5.Ozone generator
The humidifier is equipped with an ozone generator. This component generates volatile
ozone (O3) gas that kills pathogens. The ozone is transported through the humidifier and
distribution system to disinfect every component.
NOTICE
The amount of ozone generator modules varies per model:
• The EP DM4 has 1.
• The EP DM8 has 2.
• The EP DM12 has 3.
