Central air conditioning and cooling equipment Raychow spray equipment with water spray cooling fog-tech electromechanical integration equipment, industrial high pressure water purification host, pressure 4.5MPa above, by high-pressure water pipe hit by a precision nozzle section changes the jet velocity distribution, so large particles atomized droplets broken into small particles, the small particles in the aerodynamic effect of further secondary atomization into numerous 10-20 microns in diameter, "mist", "'mist' floating in the air while absorbing heat in the air from liquid into gas, increasing the humidity in the air and reduce the air temperature, which is Raychow spray cooling device works. A high-pressure pump 2 precision nozzle 3 custom chassis industry-specific equipment, for customized products.
