Thermax Dry Coolers are also known as Radiators/Remote Radiators, Fin Fan Coolers, Air Cooled
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
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.
Thermax offers two types of Dry coolers - 'V' type and 'H' type based on the application or
The fans can be mounted according to induced draft or forced draft type, depending on the
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
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
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
