  • 600RT counter flow cooling tower Counter Flow Round Type Cooling Tower NRT-600

    NRT series cooling towers' performance was strictly examined by "Quality Supervision and Inspection Center of National Glass work" in 2006, the result showed NRT series cooling towers completely comply with all national standards.   Design Features NRT series counter flow induced draft cooling tower is designed with bottle type structure, So that the volume of prevailing air is minimized. Every part of the cooling tower is designed and made precisely and further permits easy installation and endurance due to light weight and strong structure. The testing report of cooling capacity proves its high efficiency.   Casing and Water Basin Adopting small ventilation resistance packing and special designed FRP/aluminum alloy high efficiency fan, greatly reduced the motor power. Smaller motor power are designed for low noise model, save more power, double speed motor for optional to power saving according to customers’ special requirements.Fiberglass reinforced polyester(FRP) is applied with water-resistance resin and high quality fiberglass mat. With good moisture, high gel,high strength, spray the gel-coat on FRP parts by machine and is thermal formed. The surface is as smooth as mirror and could resist ultraviolet radiation. Also, it is colorfast and durable.   Fan Blades Aluminum alloy axial flow fan with adjustable pitch blades are applied and being balanced so that it can operation stably and quietly. Blades of fan can be adjusted according to the requirement of air volume.To assure that the maximum effective of exhausting air.     Fan Drive Small capacity cooling tower adopts direct drive low noise fan. Bigger capacity fan equipped with Belt drive speed reducer. Adjust belt tension through automatic spring to save the manual maintenance. Total enclosed structure can assure the low noise operation. This series of cooling tower have passed the GB7190.1-1997 quality certification of supper low noise. Further more the belt is durable without negative effect from water vapor and sunshine.   Water Distribution   The using of high coefficient rotating sprinkler heads made of reinforced plastic or aluminum alloy can reduce the pressure of friction loss. Besides, the water can be distributed evenly to achieve the max thermal performance.       Infill    Standard and low noise cooling tower are using high class thermal formed PVC sheet. The sheets are added with industrial plaits material and long fiberglass to slow the aging and increase the strength. Moreover the water film is thinner and longer so that the infill cabbage coefficient is higher. The infill is formed in the factory, instead of at construction site. To avoid uneven problem during installing. And it cold be easily cleaned and maintained in future. High temperature cooling tower is using P.P. Infill that could withstand up to 90 degreeC water temperature. The surface of such infill is corrugated to increase the filling pitch to make sure that infill is clog-free and overcome the problem of water quality.    

  • 800m³/h cross flow cooling tower cross flow cooling tower NST-800

    Features of NEWIN square type cross flow cooling tower Space saving, light-duty structures Using specially designed infill which ensure high efficient heat transferring, heat transfer area increased significantly, smaller installing area, due to the optimization design of steel structure, operating weight greatly reduced accordingly. Energy saving Adopting small ventilation resistance packing and special designed FRP/aluminum alloy high efficiency fan, greatly reduced the motor power. Smaller motor power are designed for low noise model, save more power, double speed motor for optional to power saving according to customers’ special requirements. Low noise Special designed low noise FRP/aluminum alloy material wing type axial flow fan and motor, so as to reduce the running noise of cooling tower. Lower running noise for super low noise models, fully meet the environmental friendly requirements. If double speed motor running at low speed in the night, the noise can go down by 2 to 3 db (A). The user who needs double speed motor please comment when placing the order. Good corrosion resistance Tower casing, tank and panel are make up of high corrosion resistance performance FRP material, adding light stabilizer to the gel coating to make it good anti-aging performance and not fade. Galvanized steel structure to improve the corrosion resistance performance of the cooling tower, no need additional anti-corrosion within normal service life. Convenient combination Combinations can be used to meet the requirements of different working conditions, users can decide combine or not according to the field situation. What’s more, adjust the cooling tower combination appearance according to surrounding buildings’ structure characteristics. If limited space in end user, our company can also design for the special cooling tower to meet users’ requirements for the performance of thermal and noise. Easy maintenance This series of cooling towers are modular design, air chamber of adjacent cooling towers are separated from each other, maintenance, packing cleaning, pipe cleaning, water tank cleaning can be done under cooling tower normal working.
