Operation Principle
Thermax Dry Coolers are also known as Radiators/Remote Radiators, Fin Fan Coolers, Air Cooled Heat Exchangers.
They work on the principle of convection and conduction to dissipate heat from process fluid to the air stream created by the fans mounted on it.
By suitably selecting the tube material, we can use a dry cooler to effectively cool or condense process water, chemicals or any heat transfer fluid, even if it is corrosive or contaminated with particulates.
Dry coolers are closed loop systems which eliminate any kind of water loss and thus eliminating the continuous requirement of make-up water.
Being a closed loop circuit, the water treatment cost is also negligible as compared to conventional evaporative cooling towers.
Construction
Thermax offers two types of Dry coolers - 'V' type and 'H' type based on the application or requirement.
The fans can be mounted according to induced draft or forced draft type, depending on the application.
The fans are of direct drive type, but options with gear box or belt drive are also available.
The tubes which carry the process fluid are of copper, carbon steel or stainless steel with aluminum fins to maximize the heat transfer.
We offer two variations in fin configuration based on the operating fluid temperature such as- Continuous fin and High Fin tube bundles to optimize selection.
The side panels are epoxy coated which makes it corrosion resistant and gives it an excellent appearance.
Product Range
Fluid Temperature: 30°C to 240°C with a minimum approach of 5°C above dry bulb temperature.
Cooling Capacity range: 200 kW onwards
Thermax can offer custom built dry coolers based on the application and nature of working fluids.
Advantages of Thermax Dry coolers
Modular designs of Thermax Dry Coolers helps in space optimization
Highly efficient fin to tube heat transfer
Zero usage of water which results in
Zero water wastage: Due to closed loop operation and no evaporation
No water treatment plant: As it doesn't require continuous supply of makeup water
Negligible maintenance cost: As water treatment, makeup water and replacement of fills not required
No periodic cleaning requirement
Separates process side from any contamination due to closed loop system
Plenum made of Epoxy coated galvanized iron, enhanced corrosion resistance
