NRT series cooling towers are high efficiency that designed by our veteran engineers on basis of different environment and climate around the world, with reference to China standard "medium and small sizes glass fiber reinforced plastics cooling tower GB7190.0-2008", which fit with various environmental changes in different countries, better solved the problem that environment changes affect the cooling effect of the cooling tower, which also guarantee the matched equipment run normally and save energy to the largest extent.
Features:
1. Frame
Designed by using chains structure, the frame is stable and with good rigidity. The load is evenly distributed among each foundation, which makes operation more smooth. All structure parts are processed by hot assault zinc and has excellent performance of anti-rust and anti-corrosion.
2. Glass fiber reinforced plastics
Using good quality surface sizing, UPR and glass fiber as raw materials, with standardized abrasive tools for production, glass fiber reinforced plastics surface is glossy, evenly colored, aging resistance, fastcolours and durable.
3. Motor
Using totally closed cooling tower's exclusive motor, protection level IP54, good sealing, which is suitable for running in damp and hot environment with low noise and long lifetime.
4. Fan
Using wide blade, raked space twisted, low rotate speed and aluminum alloy axial fan, which is low rotate speed, large air quantity, low noise in operation and good dynamic balance etc., its angle is adjustable, which suits customers' requirements on air quantity and noise etc. Aspects very well
5. Reducing gear
Reducer casing using imported bearings and triangle belt, which guarantee cooling tower's reducing gear run smoothly with low noise and makes tower's lifetime longer.
6. In fill
Made of good P. V. C plain film that is processed through hot water heating and compression, which makes cooling tower's reducing gear run smoothly with low noise and lifetime longer.
7. Sprinkler head
Using aluminum alloy, imported bearings inside, high precision installation, close fit, smooth running, long lifetime.
8. Water basin
Designed on basis of large water reservation and high water level, which avoids pump-out while starting and guarantees equipment run normally.
