Misting and Humidification in Greenhouse

Mist systems are an important part of any greenhouse operation, as they play a vital role in the production of both seed and vegetative plant material. Their fundamental purpose is to deliver an intermittent source of water in low volumes to plant material being vegetatively propagated or to seeds being germinated. Mist systems, when compared to irrigation systems, typically deliver a smaller particle of water for shorter intervals of time. Depending on how a mist system is used and the type of crop it’s being used on, the crop’s production period can either be accelerated or slowed.

The greenhouse humidification and spray equipment can effectively control the humidity and temperature in the greenhouse, effectively adjust the plant growth environment, promote crop production, and use the high-pressure spray system to solve the problem of cooling in the greenhouse in hot seasons.

RELAB supplies various low-pressure and high-presure mist system and components for greenhouse humidification, including misting pump, nozzle, slip lock and compression type fittings, especially the high-pressure slip lock fittings which made from SS304 and SS316, they can work on 70-80 bar.

RELAB Greenhouse humidification and spray equipment are mainly used in large, medium and small greenhouses in agriculture. The principle of greenhouse humidification and spray equipment is to use a high-pressure pump to pressurize the water to more than 40 kg, and atomize it through the high-pressure pipeline to the high-pressure mist nozzle to form flying rain threads, create good and fresh air, and the mist droplets evaporate quickly, thereby increasing the air humidity. , reduce the ambient temperature and remove dust and other multiple functions.

The greenhouse humidification and spray equipment cool down through the cold mist sprayed by the high-pressure mist nozzle. These high-pressure mist nozzles can generate 5 billion droplets per second, and the diameter of the droplets is only 3~15μm, just like the clouds in the mountains and the cooling effect is good. The cold mist can evaporate quickly and does not wet the ground. Preliminary experiments in the greenhouse show that the use of this system can effectively reduce the temperature of the greenhouse and improve the growing environment of crops.

In addition to the functions of cooling, humidification, and dust removal, greenhouse humidification and spray equipment also has multi-purpose functions such as spraying, disinfection, and cleaning. In the industrial industry, it has the effect of killing multiple birds with one stone. The system has low cost, low operation and maintenance cost, economical and practical, and can realize unmanned automatic control. It is better to use it alternately with cooling equipment such as wet curtains and fans to create a fresh air, comfortable and cool greenhouse in hot seasons and increase the yield of greenhouse crops. Greenhouse humidification and spray equipment is an energy-saving and environmentally friendly product.
