False Ideas
Misting can cool down relative air temperature by 15°C: FALSE
In our temperate regions of mainland France, this is unthinkable!
The temperature can be reduced at best by 5 to 7°C in the driest and hottest regions. Around the seaside, one can generally reduce the temperature by 1 to 3°C. Reducing the temperature is possible and really works (see purposes - cooling).
Generally, cooling will be more efficient when there is a higher temperature and lower hygrometry. A decrease of 15°C is possible in extreme weather conditions such as one can find in the desert (Marrakech,...).
For example, in normal weather conditions (T=30°C and RH=50%), after misting, one can obtain: T=26°C and RH=70%, a reduction of almost 4°C.
Misting can cool down offices and closed spaces: FALSE
Misting cannot cool down a closed space!
Misting can cool down the relative air temperature. The difference is outstanding. Cooling by air condition is a physical cooling process that passes through a heat exchanger. The air in the room is not necessarily renewed.
In misting, the water is pulverized into micro-droplets in the air. This water evaporates and the process reduces the ambient temperature and increases the hygrometry. The air not being renewed will result in its saturation (100% hygrometry) and the condensed water will remain in a liquid state.
In misting, the renewal of the air is necessary for cooling. It can only be efficient in a well ventilated area (hall, train station, open workshop, outdoor terrace,...). These properties should be taken into account when proceeding with calculations to install a misting system inside a building.
Misting is a watering system: FALSE
Misting can humidify but it is not a watering system!
DID Clim high pressure misting is a procedure that disperses micro-droplets of water into the air. Even when the air is saturated (100% hygrometry), the quantity of water disseminated by misting condenses, which does not wet objects sufficiently. This is too weak to compensate for the transpiration of most plants.
An additional watering system must then be installed along with the misting system.
Sanitary measures are not important in misting: FALSE
Maintenance is not important in misting: FALSE
A defective design and a lack of maintenance in a misting system can be fatal!
The bacteria present in the water that is to be dispersed into the air can be extremely dangerous. The prevention of sanitary risks in a misting installation should be the first priority of the operator.

We have developed a system called DID Bio Protect to handle these problems. We insure though this process an automatic maintenance of misting equipment.

A well integrated and esthetic misting installation is impossible: FALSE
We are working on developing esthetic solutions to discreetly integrate the misting installations into the surroundings. Our DID Line (PCT patent) designs are perfectly adapted and bring a practical and personalized solution.
They assure an immaculate and discreet finish. The product range of DID Line designs has been conceived to facilitate the arrangement of the nylon tubes and the easy to install connections of the misting system.

In certain cases, we recommend the use of stainless steel lines the quality of the finish being unbeatable. For more information, visit our page [stainless steel lines]
Residential air [brewers], a solution adapted to misting: FALSE
Certain terraces are equipped with air fans and misting systems. Generally, one does not want to be caught in the breeze produced because it is very unpleasant.
Air fans are [axial helicoids] fans that have quite a weak performance and are very noisy. Moreover, to not look like industrial turbines (that can have an excellent productivity rate), they have a “pleasant” design which makes them into “aerodynamic waste bins” (high rate of recycling the air between the upstream and downstream movements of the fan, high speed propellers,...).
Finally, most of these air fans are made in South-East Asia with quality requirements inferior to ours and which are simply pieced together in Europe with misting ramps that are brought-back. This is not a properly finished product (problems with corrosion, with water-resistance, with weather resistance, with electrical compatibility (water/electricity),...).
The solution:
In terms of portable misting, it is better to use products that are specifically designed for ventilated misting. The DID360 has become especially notorious among professional clients. Its silent functionality, water-resistance and high aerodynamic productivity, without an air flux and water flux aimed directly at the users, make it a product highly recommended by professionals.

Nylon tubing is not adapted to high pressure misting: FALSE
The high pressure nylon tubing that we use is specially designed for high pressure misting!
Its bursting point at 20°C is above 190 [bars]. Moreover, the sites that we have equipped many years ago are proof of its sustainability. Whether it be in hot (Morrocan desert,...), cold (Luxembourg,...), dry and humid environments, it has demonstrated its dependability through these tests.
For a perfectly finished installation of high pressure nylon [ramps], it is essential to use [DID Line designs].
In misting, one needs a minimum pressure of 100 bars: FALSE
Most of our colleagues use nozzles that require a minimum pressure of 100 to 120 bars to function. Bellow this, their nozzles generate water drops that are too large and that wet.
Our nozzles are specially developed for high pressure misting at 55 bars guarantee water-droplets of 5 microns on average. 90% of the droplets have a diameter inferior to 10 microns. This misting quality is the envy of our competitors but is never matched.
