Misting systems work by forcing mains water via a high pressure pump module and tubing through a specially designed mist nozzle. The brass and stainless steel nozzle has an orifice size of .02mm, thereby producing a micro-fine mist.
The millions of water droplets created are so small that they instantly flash evaporate and absorb the heat in the air. Flash evaporation can reduce the surrounding air temperature by as much as 14 C° in just seconds. Ozmist pump modules pressurize water to 1,000PSI. or 70 BAR.
Static Misting Systems
Consist of either a high pressure nylon or stainless steel tube with a series of nozzles inserted in a line. Static systems are commonly used to cool outdoor and indoor areas, provide constant humidification in green houses or dust suppression.
Stainless steel misting rings are commonly fitted to the face of high velocity fans for greater cooling effect. As with our other systems, misting fans use the process of evaporative cooling, otherwise known as Thermal Dynamics. The hotter it is, the quicker evaporation will occur. The quicker the evaporation, the more heat is used in the energy exchange process and the better our misting fans will work. Fans are normally used inside buildings and spread around the area to be cooled. Fans are linked by a high pressure nylon tube to the pump module. Multiple fans can be connected to one pump module.
Q: What sort of temperature reduction will I achieve?
The amount of cooling that can be achieved will depend upon a number of factors. Basically the hotter the ambient temperature and the lower the relative humidity, the quicker evaporation will take place, giving a greater temperature reduction.
Many companies claim that their misting systems are capable of reducing temperatures by up to 22°C. Working from a psychometric Chart this is feasible but it is very unlikely that you could ever achieve such a reduction in temperatures. In our experience it is possible to gain a temperature reduction of between 10° to 14°C in low to medium humidity conditions.
