Closed Circuit Cooling Tower: Cross Flow, Counter Flow & Mixed Flow Coolers

To put it simply, closed circuit cooling tower has two separate circuits, that is, an internal circuit and an external circuit.

• Internal circuit: Docking with the targeted equipment, it forms a closed loop to cool the equipment, remove the heat of the equipment and transfer it into the cooling units.
• External circuit: In the cooling tower, it cools the tower itself. It will not contact with the circulating water in the internal circuit directly. It only undertakes heat transfer and dissipation via coil exchanger within the tower. In this cooling mode, through automatic control, motor operation is set according to the water temperature.

Closed circuit cooling tower generally consists of tower body made of stainless steel or galvanized plate, heat transfer (it can be single coil exchanger, tubular exchanger, a combination of coil exchanger and packing or a combination of tubular exchanger and packing), fan, spray system, PVC drift eliminator, water tank and circulating water pump.

• All-round corrosion protection
  • Tower body is made of stainless steel 304 or DX51D+AZ120 aluminized zinc plate.
  • Coil is constructed of stainless steel or copper pipes.
  • Framework and lifting lugs are made of hot galvanized plate.
  • Bolts and fasteners are made of stainless steel materials.
• Stable tower structure
  • Reasonable reinforced framework design
  • The joints of the tower body are fastened with bolts and bolts are reasonably and densely arranged.
• Great cooling effect
  • Advanced system design
  • Efficient fan
  • High quality coil, packing and heat transfer
• 100% cooling capacity assurance
  • We have professional thermal performance test platform.
  • All series of products have passed normative tests.
• Various design types for your option
  • Counter flow cooling tower
  • Cross flow cooling tower
  • Mixed flow cooling tower
• Easy maintenance, repair & cleaning
  • Cross flow & mixed flow cooling towers are equipped with large access doors and channels.
  • Counter flow cooling tower maintenance does not require whole tower disassembly. Remove panels at the ends of water condenser and the maintenance can start.
  • Efficient water tank can avoid channel blockage and reduce cleaning frequency.

According to water flow direction and air intake direction, closed circuit cooling tower can be divided into counter flow cooling tower, cross flow cooling tower and mixed flow cooling tower.

In the counter flow closed circuit cooling tower, the air is introduced at the bottom of the tower and flows from bottom to top, in the opposite direction of spray water, therefore, it is named as counter flow closed circuit cooling tower.

In the cross flow closed circuit cooling tower, the air is introduced from the side of the tower and flows horizontally, making a right angle to the direction of spray water, therefore, it is named as cross flow closed circuit cooling tower.

Mixed flow closed circuit cooler has two air inlet directions. In one direction, the air enters from the top of the cooling tower and flows from top to bottom, in the same direction as the spray water. In the other direction, the air enters from one side of the tower at the bottom and flows from bottom to top, in the opposite direction of spray water, therefore, it is called as mixed flow closed circuit cooling tower.
