- Modular design,high strength, good rigidity, nice appearance.
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, Low Noise
Adopting small ventilation resistance packing and special designed FRP/aluminum alloy high efficiency fan, greatly reduced the motor power. Double speed motor for optional to power saving according to customers' special requirements.
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. If double speed motor running at low speed in the night, the noise can go down by 2 to 3 db (A).
Good Corrosion Resistance
Tower casing, tank and panel are made up of high corrosion resistance performance FRP material, and Galvanized steel structure improves the corrosion resistance performance of the cooling tower, no need additional anti-corrosion within normal service life.
Convenient Combination and Easy Manitenance
Combinations can be used to meet the requirements of different working condition.If limited space in end user, we can also design for the special cooling tower to meet users' requirements for the performance of thermal and noise.
Components Instruction
Motor
Fully enclosed type, with protection grade: IP55, and insulation class: F. Smooth operation, low failure rate. Options: Siemens, ABB motor, etc.
Fan and Reducer
Adopting low speed, big chord length and width of blade fan, with characteristic of stable wind speed, low noise, few eddy current and high efficiency, etc. Enough air flow can be easily get at low rotating speed of the fan, what's more, the cooling tower fan blade angle can also be adjusted according to different climate condition, therefore, the cooling tower can not only be ensured in the rough conditions but meet the operation requirements of users.
Infill
Brand new PVC infill is vacuum formed of 0.3 thickness or more thicker PVC film with excellent chemical and high distortion resistance, big coefficient of heat transfer, small wind resistance, high ventilation performance.
We have different materials to suit different water temperature. What's more, the PVC filler's compact package design is convenient to take out for cleaning, and the special designed configuration of the filling incorporates the function of drift eliminator, louver and wet deck surface.
Steel Structure
Hop-dip galvanized steel framework to keep the cooling tower great performance and long lifespan, good anti-corrosion, guarantee the use of more than 15 years. Stainless steel hardware parts are also available for options if somewhere special condition needed.
Distribution System
Hot water distribution system is used F.R.P parts, non-corrosive and long life, and are specially designed for uniform distributing and ease of inspection. A distribution cover is attached on top to prevent water from splashing out and other dirt to come into the water.
Inspection Door
Inspection doors are used to provide a convenient access to the interior for inspection, maintenance, adjustment of the internal parts, like float valve, cleaning up the lift-out strainer and flushing of the water basin.
