The light gray color of the shell is our factory's main color, which fully meets the requirements of the owner.

Lowest noise and most cost-effective

Fan:

Select high-strength aluminum alloy new type large chord arc cooling tower dedicated fan, with high air volume, low noise, and light weight. Surface processing8High adhesion spray anti-corrosion treatment, anti-corrosion and anti-oxidation. Adjustable blade angles meet different requirements and are easy to install and maintain.The number of fan blades should not exceed 4, and the blades should be easy to assemble and disassemble;

Inverted installation of the fan can reduce the noise of the cooling tower3-5dB（A）The beam above the air outlet limits the space.

electric machinery:

Adopting world-renowned brandsABBFully enclosed dedicated cooling tower motor, protection levelIP55Insulation levelFGrade, after more than ten years of use, it has outstanding performance and high efficiency,Low noise and low energy consumption.

Good heat dissipation effect and less floating water

Packing:

Select high-quality polyvinyl chloride（PVC）Material, vacuum formed, with high strength and flexibility, UV resistance, and resistance to crackingNo pores, no bubbles, no obvious impurities, and poorly dispersed auxiliary materials, with no oil stains on the surfaceNo irritating odor,Environmental protection, flame retardancyLong anti-aging life. And the pattern adopts a unique design“V”The waveform diagonal design can effectively extend the contact time between water and cooling air inside the tower, with low wind resistance, good hydrophilicity, and high heat dissipation efficiency. The end is equipped with a honeycomb water collection device to reduce the floating water loss to the circulating water volume0.01%Working water temperature-50℃～58.5℃If it exceeds this value, please chooseP.PMaterial: High temperature resistant filler.

Uniform water distribution and easy maintenance,The packing sheet has good thermal and resistance characteristics, which can fully meet the requirements of cooling tower heat exchange and flow field design. The filling frame and ladder are both made of hot-dip galvanized pipes.

Water distribution system:

Based on years of manufacturing experience and the latest design theory in the international cooling tower industry, the "Dongyang" brand cooling tower adopts a sprinkler basin type water distribution, with low water pressure entering the tower, energy saving, uniform watering, and no moving parts. In addition, the installation of a maintenance channel in the middle of the tower makes maintenance and repair more convenient.

Durable and long-lasting

Aluminum cable structure for external connecting parts:

Using special aluminum alloy material, it has excellent rigidity and strength, light weight, and easy installation of external connecting pipes; The sealing of the cable tube interface is high, and the force on the connecting port is uniform; Surface processing8High adhesion spray anti-corrosion treatment, anti-corrosion and anti-oxidation.

Unrestricted environmental temperature conditions for use:

High temperature or sewage environment:

Circulating water temperature exceeds58.5℃，PHValue exceeds6-8Containing strong acids, strong bases, and total solids in water exceeding5000mg/LOil (tar) content exceeding10 mg/LOr contain a diameter greater than5mmWhen dealing with mechanical impurities, special design and production are required.

Low temperature environment:

When using continuously in low-temperature and icy environments in winter, it is necessary to design and install electric heaters and sprinkler guide rings to prevent water from flowing onto the louvers and prevent icing.

Cross flow type（RT）Advantages of double-sided air intake square cooling tower for water tons:

Extremely low noise

The noise of a cross flow cooling tower is mainly divided into two types:

The first type: wind noise

The governance plan we have adopted is

AAfter long-term testing and on-site inspection by users, our company's aluminum alloy wide blade and large chord arc cooling tower dedicated fan has a noise reduction of at least 3Db compared to fans of the same specifications;

BAdopting the well-known domestic brand ABB high-efficiency and low-noise fully enclosed cooling tower dedicated motor, coupled with imported belts (high temperature resistant, wear-resistant) and pre factory drive parts for static balance treatment, the controllable noise is minimized;

CThe transmission part is equipped with a low-speed transmission method to further minimize noise;

The second type: water noise

The governance plan we have adopted is

AInstall a cover plate on the sprinkler basin to completely seal the noise caused by water entering the pipeline inside the sprinkler basin;

BUpper control of sprinkler layer: The water drop height from the sprinkler basin to the filling material is 180mm, and the surrounding area is fully sealed in the tower with fiberglass plates;

CLower control of water spraying: The filling material is inserted into the water collection basin to a depth of about 50mm, and there is no sound of water falling;

DEquipped with an automatic float valve water replenishment device to prevent the cooling water in the collection basin from being emptied and making noise;

EInstall air inlet louvers around the inlet section to control the sound of water falling from the filling material to the collection basin inside the tower;

Very little floating water:

the EastWhether it is a counter current or cross flow cooling tower, the loss of floating water in the cooling tower is extremely small. The solution we adopt is:

AThe transmission part is equipped with a low-speed motor;

BThe connection port of the sprinkler system is fully sealed;

CThe two sides of the filling end are equipped with honeycomb shaped water collection devices;

DThe connection edge of the fiberglass shell has good sealing performance, and sealant should be applied if necessary;

EInstall inlet louvers around the inlet section to further control water droplet loss within the tower;

FThe water collection basin is equipped with an overflow device, which prevents it from overflowing when the flow rate or replenishment is too high;
