INDUCED DRAFT cooling tower
TCD Counterflow Closed Circuit Cooling Tower
TCD Series is a closed circuit, induced draft counter flow, film filled, galvanized steel multi-cell cooling tower. The heat exchange coil packs are made of seamless deoxidized copper or stainless steel tubes with high heat transfer efficiency and anticorrosion. The steel construction offers a non-corrosive structure for extended service life. TCD features a compact footprint with excellent heat exchange and reduced maintenance shut down periods.

Three Separate Circuits are Formed:
Four steps are taken by the process fluid as it circulates inside the coil to transfer the heat load: 1. The movement of the fluid inside the coil transfers the head load of the process fluid to the internal surface of the coil. 2. Heat load is transferred from the internal fluid to the external surface of the coil through the pipe wall. 3. Heat load is transferred from the coil’s surface to a water film that is sprayed on top of the coil. 4. Lastly, a piece of the water film evaporates, transferring heat from the water film to the atmosphere.
Spray water is introduced into the water distribution system by the spray pump from the tower’s water basin, where it is pumped up to the spray nozzle and falling through the filling section and mixed with the ambient air. A cycle is then started when cooled water falls over the coils as a thin film, absorbing heat that has been transmitted from the inside of the coil to the water basin of the tower.
The fan draws surrounding air into the coil and filler, where it will collect heat from the water spray, and release the heat into the atmosphere through the drift eliminator.
The modular cooling tower design enables segment assembly at the factory before delivery. Three main sections make up the structure: the spray box section, the filling and coil box section, and water basin. To speed up construction, the cooling tower may be quickly put together by the crane once it arrives at the project site.
High Efficiency of Chiller:
Water in circulation does not come into contact with air as it circulates inside coils, maintaining constant clarity. The system is made to prevent scale or debris from building up inside the chiller and pipework. As a result, the chiller has great efficiency, low power consumption, and minimal maintenance costs.
Low Drift Loss and Low Sunlight Contact:
S type drift eliminators are installed in air discharge to minimize the water drift. Louver of air intake can prevent splash out and restrict sunlight and dust to reduce algae development and clean water.
Handrail and Caged Ladder
