1. Cooling capacity for one cell is 800 to 4500m3/H, relevant refrigerationton is 1180 to 6640. Several cells can be fixed together. 2. Body frame: A. JBNG series: Made up by steel bar, round and square steel pipe. All components are hot dip galvanized or handled with other special embalmment. Thus it is anticorrosion and high intensity. This steel structural framework is stable to stand typhoon of 12th degree and earthquake measuring 7.0 on the Richter Scale. The tower flat can bear pressure bigger than 200 kgf/m2. B. JBNS series: Made up by reinforced, cement and concrete. The whole structure is featured by stability, low vibration, anticorrosion, and long service life. Supportand casing components are hot dip galvanized or handled with other specialembalmment. 3. Casing: Made of reinforced compound material. The body surface is imported colorizedgel-coat surface, which contains ultraviolet radiation absorbefacient. As a result, its surface is smooth and clean, corrosion-free as well as antiultraviolet. This kind of surface will bear aging and fading. Customer may the color freely. 4. Drive system: Use horizontal shaft drive gear reducer. For easier maintenance, motor is fixed outside fan stack while oil ruler outside fan stack. All the motors, fans, reducers are most well-know manufacturers in China. Standard motor is of single speed, but if customer requires specifically, we can also provide double or three-speed motor. As to fan and reducer, we can customer ed brand or use imported ones. 5. Distribution system: Use distribution pipe fixed with advanced gravitational nozzle in the world. It may work at low water supplier pressure, sprinkle water equally, and never jam. 6. Sprinkling fill: Use high efficient PVC fill. The piece mould is tested by authority department, compared to other fill, it has such advantages as larger surface, small air resistance, good hydrophile, large heat transfer coefficient, firm assembly, never jam, easily to clean, good fire resistance and bearing aging. The fillcan work at high temperature 35oC to 65oC. 7. Eliminator and louver: Use national advanced special three-dimensional eliminator, impact of which is rather remarkable, with drift loss of less than 0.005 percen
