NC series open circuit cooling towers are developed for industrial process cooling applications with their compact design and reliable performance.
Components
Outer Covering of Tower
As standard, it consists of corrugated galvanized iron sheet or breakage-resistant plastic sheet. It is mounted on the tower in a manner that prevents any air leakage.
Fan
It is specially designed for NC series towers. The fan is manufactured from cast material, with aluminum casting material used for corrosion resistance. It is fully balanced both statically and dynamically, and its blades are adjustable.
Mechanical Elements
The drive shaft, which is manufactured from electro-galvanized steel, is supported from two different points by heavy-duty ball bearings. The vibration problem has been solved thanks to a specially designed elastic coupling or belt-idler mechanism. Noise levels have been reduced to low decibel values in NC towers. A specially designed drive system with a reducer can also be used.
The Hot Water Distribution System
Minimum pumping pressure and long operating life are provided by the natural-flow water distribution system manufactured from hot-galvanized or epoxy-painted steel. Natural-flow water distribution is achieved by specially designed polypropylene water jets.
The Honeycomb Eliminators
The eliminators, manufactured from plastic polystyrene, help reduce the power required from the fan thanks to their efficient airflow characteristics. Their inspection and maintenance are easy. The eliminators effectively retain water droplets carried by the air because they are mounted in a double-pass configuration. Drift loss is below 0.2%. The eliminators can also be specially manufactured from PVC.
The Fan Cylinder
The fan cylinder, manufactured from hot-galvanized or epoxy-painted steel, is designed to provide easy airflow into the fan and therefore ensure efficient operation of the tower. It is also protected by a steel-wire cage that prevents foreign substances from entering.
The Air Access Shutters
The air access shutters are manufactured as standard from corrugated Eternit or breakage-resistant plastic sheets. They are designed to ensure uniform airflow and minimize freezing problems. For inspection and replacement during maintenance, the shutters can be easily dismounted and mounted.
