36. to raise the relative humidity The atomizing humidifier is an efficient humidification system that is especially suitable for larger installations where high flow rates of water are required without the necessity of excessive energy expenditure When the humidity value in the environment is less then the desired value as measured by a probe or external controller the controller starts the volumetric piston pump which sends the treated water to the nozzles The treated water using a reverse osmosis or deionizer system is pumped at a pressure of 1000psi 75bar and sent via the connection pipes to the atomizing nozzles The nozzles then reduce the jet of water into a multitude of very fine water droplets 10 20 microns Because of the fine droplet size the water can then easily change its state and vaporize The energy required for this transformation is supplied by the ambient air at a rate of 690 W per liter hour Consequently there is a decrease in temperature in the environment being humidified and this process may be useful in many applications adiabatic transformation The humiFog unit must be supplied with treated water for the following reasons e To reduce the introduction into the environment of dust due to the mineral salts found in the untreated water e Tominimize the clogging of the nozzles probes external regulator ATOMIZING MANIFOLDS ATOMIZING NOZZLES 800 1 000 psi Mist Eliminator 1
