Mixed Flow Closed Cooling Tower

Closed cooling tower is an efficient and energy-saving cooling equipment, which is widely used in industry, commerce and HVAC systems. Different from the open cooling tower, the closed cooling tower exchanges heat through a closed circulation system, which avoids the direct contact between the cooling medium and the outside air.

Mach cooling can provide customers with a variety of cooling equipment and processes, which mainly include closed-circuit cooling towers, open cooling towers, air coolers, and industrial water tanks. At the same time, it produces and operates various specifications of cooling tower packing, cooling tower fans, cooling tower motors, reducers, and other fiberglass cooling tower accessories. It also undertakes cooling tower renovation and maintenance services. The company's products can be widely applied in areas such as high-speed railways, precision air conditioning, metallurgy and forging, oil and power, chemical and pharmaceutical industries, and heat treatment.

Mixed Flow Closed Cooling Tower Features

• Efficient cooling

  
  

  Mixed-flow closed cooling tower adopts efficient heat exchange design, which can quickly and effectively transfer heat from cooling medium to ensure stable cooling effect.

• Water-saving and energy-saving

  
  

  The closed circulation system greatly reduces the evaporation loss and splash loss of water, and the water circulation utilization rate is high, which significantly reduces the demand for water replenishment and saves water resources.

• Stable operation

  
  

  The circulating water of closed cooling tower usually adopts soft water closed circulation, which effectively prevents the equipment from being damaged by scale generated in the tower or user equipment during long-term use.

• Environmental protection

  
  

  The circulating water of the closed cooling tower through the closed inner circuit is not polluted and can be used continuously. The relative evaporation of spray water is less, which protects the environment to a great extent. 

• Easy Maintenance

  
  

  Since the cooling medium circulates within a closed system, it prevents the entry of external impurities and contaminants. This significantly reduces issues such as scaling and corrosion in the cooling system, extends the equipment's service life, and decreases maintenance workload and costs.

• Intelligent control

  
  

  Closed cooling towers are usually equipped with fans and pumps controlled by frequency conversion, which can dynamically adjust the running state according to the actual cooling demand to avoid unnecessary energy.

• Low noise design

  
  

  Closed cooling towers usually adopt low noise design, and the frequency conversion control of fans and pumps further reduces the operating noise and improves the working environment.

Mixed Flow Closed Cooling Tower Application

Mixed-flow closed cooling tower is suitable for many industrial fields, such as metallurgy, aviation, electric power, chemical industry, machinery, petroleum, food, plastics, rubber and so on.

Mixed Flow Closed Cooling Tower Maintenance Precautions

1. Maintenance of equipment：

Regularly clean the dust, oil stains, and other debris on the outer shell, and also remove the scale on the heat exchange coil. Regularly clean the spray filter. The scaling material is the biggest influencing factor on the heat dissipation effect of the heat transfer coil.

2. Water quality management and maintenance：

Due to the good heat dissipation effect inside the heat exchange coil and long-term exposure to hot water circulation, it is relatively easy to scale. Therefore, soft water must be used for the internal water of the heat exchange coil. The outer layer of the cooler is sprayed with a spray pump, and the spray water is tap water. If it frequently comes into contact with hot copper pipes, scaling will definitely occur, and it should be regularly cleaned.

3. Maintenance and upkeep of pumps：

① The inlet pipe must be highly sealed;

② The imported pipeline must be filled with liquid, and the pump is prohibited from running for a long time in a cavitation state;

③ Regularly check the current of the motor and ensure that it does not exceed the rated current of the motor;

④ The pump should be supervised by a dedicated person during operation to prevent accidents;

⑤ It is strictly prohibited to arbitrarily turn off the cooling water supply during high temperature operation;

⑥ After long-term operation of the pump, if the noise and vibration of the unit increase due to mechanical wear, it should be stopped for inspection. If necessary, vulnerable parts and bearings can be replaced. The maintenance period of the unit is one year.

4. Maintenance and upkeep of mechanical seals inside the pump：

① Mechanical seal lubrication should be clean and free of solid particles;

② Mechanical seals are strictly prohibited from working under dry friction conditions

③ Before starting, the pump (motor) should be turned a few times to avoid damaging the seal when suddenly started.
