All kinds of Fresh produces humidification with Misting
Cool Group misting system re-establishes to optimal values the humidity level, blocking dehydration process, keeping the freshness of food for longer time
Our misting system periodically emit an ultra-light mist of water directly onto the product or goods usually for 1 to 5 seconds every 10-15 minutes. Due to their teeny dimensions, these small water droplets evaporate without wetting, keeping humidity and coolness in the environment air, reducing dehydration and maintaining product weight and condition.
Without the proper level of humidity, vegetables and fruits suffer. Produce that shrinks, wrinkles or spoils quickly likely has been stored in too high or too low humidity.
Fruit and vegetables are largely composed of water. The loss of freshness is mainly due to a quick dehydration of the product, further to the evaporation of the water. Water evaporates, due to a difference between its values contained into the vegetables and in the surrounding air. By means of a misting system, the humidity level in the air re-establishes its optimal values, blocking the dehydration process. Additionally, a misting system, following the adiabatic principle, reduces the temperatures and cools the products displayed at the counters.
Vegetables needing high relative humidity between 85 percent and 95 percent include asparagus, beets, broccoli and cabbage, carrots, cauliflower, celery, beans, peas, radishes, corn and turnips. Greens, scallions and lettuces also need high humidity, but should be kept separate. Keep things dry, below 85 percent humidity, for pumpkins, squash, onions and garlic.
Fish products are also subjects to the loss of freshness by dehydration, as they are composed of water in the measure higher than 70%. Moreover, the misting system can control the spread of smells in the surrounding areas. Misting system can be easily assembled inside refrigerated displays.
Some types of meat and cold cuts are subjects to dehydration, too: our fog systems can restore naturally their suitable special microclimate, to preserve or keep seasoning them. Misting system can be easily assembled inside refrigerated displays.
In few cases, greenhouses may require cooling systems. This occurs when the daily average temperature is too high for the crops / plants to function properly. In this case, cooling the greenhouse is the only way to keep the crops inside healthy and productive. Cooling a greenhouse is more expensive than heating a greenhouse. An investment in a cooling system must therefore be a well-considered decision.
Misting systems are used with enormous advantages to keep the right climate inside greenhouses of any dimension.
Misting systems (or Fog systems) play an important role in the greenhouse climatic control. They are also used with enormous advantages to keep the right temperature and humidity in the environment, under conditions of forced or natural ventilation.
In summertime the quick evaporation of the fog will cool the greenhouse due to the principle of evaporative cooling, meanwhile it humidifies the environment in case of low relative humidity. During the wintertime or in cold season the system keeps the correct humidity rate preventing the dehydration of the crops caused by heating systems. The environment produced by our Mist & Cool misting system is appropriate for the most delicate crops (ex. the growing of young seeding, the cultivation of tropical plants and in bloom plants) where it is not possible to use traditional spraying methods like standard spraying.
Fog system works on a pressure of 1000 PSI (70 Bar) and it is designed to produce water droplets smaller than 5-10 microns diameter that, for theirs dwarfish size remains suspended in the air for a long time producing the fog effect.
Typically all growers have the problem of low humidity and high temperatures. Serious problems occur when the humidity in the greenhouse environment drops below 30% RH. Plants / crops will suffer and typically slow or halt the growing process. In fact, many greenhouses in arid conditions close down for the summer months until ambient temperatures will reduce to an acceptable level.
Very low cost of our systems are an important aspect of misting in greenhouse, if compared to other solutions for the climate control. The energy costs are low, simple and fast installations, considering that the systems are supplied in various solutions or D-I-Y Kits, or by the simple solutions of quick couplings. Our systems are designed to operate with very low costs and with a minimum maintenance.
Another preferred cooling method for a greenhouse is through evaporative cooling. Evaporative cooling is the process of having particles of water evaporate, which leads to a drop in temperature through increased humidity.
There are two systems which use this principle in commercial greenhouses: high pressure fogging and the Pad & Fan cooling system. In the few years, semi-closed greenhouses have been developed based on the same principles as the Pad & Fan system.
The Pad & Fan cooling method is a widely applicable cooling system due to its simplicity. As the name indicates, it uses a combination of wet-pads and ventilators. A set of a huge / big fans blow air out of the greenhouse, causing a suction-draught through the greenhouse area. On the opposite sides of the fans, the pad-walls are installed which are kept wet through the water line system. The suction-movement caused by the fans, forces hot outside air to be pulled into the greenhouse through the wet pads. Water from the pads evaporates into the hot air, increasing its humidity whilst lowering the temperature.
Wood factory and manufacturing, such as its storage, benefits from environment control. Wood is a hygroscopic material that absorbs or releases water depending on the relative humidity. In high relative humidity conditions, wood absorbs humidity, until obtaining the same level of the surrounding air. During the 2/3rds of the year, the relative humidity is insufficient for manufacturing and varnishing processes.
Misting systems maintain the proper moisture content inside the wood fibers and efficiently reduce many of the quality problems associated with woodworking, preventing: shrinkage, swelling, deformations, splits and cracks. These situations are caused by different humidity values, varnish diffusion problems, static electricity and dust.
Compared to alternative methods such as dust extraction or collection, suppressing dust with fog can be done at a fraction of the price. Capital cost, running costs and power consumption are all significantly lower than power-hungry extraction or collection machines. Misting systems emit fine controllable fog, which suppresses airborne dust without wetting. This protects your staff against dust–related respiratory conditions such as silicosis and COPD. The microscopic water droplets agglomerate dust, forcing it to fall from the air.
Dry air in a theatre is uncomfortable for singers, actors, audiences. A “comfort zone” humidity level must be obtained to prevent dryness of the mouth and other vocal annoyances during live performances and presentations. In addition to overall ambient comfort, a theatre misting system helps to reduce the dust in the air that can be annoying to actors, dancers and singers.
Adequate air humidity makes the environment more at ease and comfortable and protects the respiratory tract ensuring that actors, singers, dancers and musicians feel good in their workplace.
Creating the right environment is a rigorous process. Nozzles must not be visible, and residual water droplets must be avoided. Because every theatre, cinema, platforms and Opera are unique. Cool Group work with the managers to maintain the best humidity level for the audience, the performers, and the patrons.
