Cross Flow Closed Cooling Tower
Application:Casting, forging, air compressor, central air conditioner, ground source heat pump, printing machine
This type applies to the project which needs a large cooling range ( △T = 15-45 ℃ ) , and which place has requirements to keep low noisy and environmental protection , such as hospital and City Center.
The difference between the closed cooling tower and the open cooling tower is: The closed cooling tower exchanges heat between the cooling medium and the cooling water and air outside the tube through the coil, forming a closed circulation system, avoiding the cooling medium and the air. Contact and lead to pollution, resulting in the waste of cooling medium, equipment blockage and other failures that affect normal use.
The heated working fluid inlet from cooling coils,then the waste heat be took away by the fall down spray water and cross flow with the cold dry air which is inlet from the sides of the tower and form to saturated vapor in the process. The heat is exhausted out of tower by the top fan and the water is collected to bottom tank and circulate continuously by the special evaporator.Different from Counter Flow type, there are PVC fills inside.They per-cool the spray water, and flows in the vertical direction with cold water inlet, it will make more effective.
1. Low noise
PVC fills make high work efficiency and also can reduce the noisy of spray drops. Configure low noise fans.
2. Avoiding scaling
The spray water’s temperature is lower than scaling temperature, smooth flow the cooling coil and the coils are damped completely, highly reduce scaling.
3. Convenient Maintenance
Modular design is easy to assemble, disassemble and maintenance.There is a maintenance passage inside the tower.It can be repaired and cleaned without stopping the machine.They are maintenance ladder and fence,which are convenient for staff to entrance to examine and repair.
