IWC Package Cooling Towers
We offer the full range of iconic IWC industrial cooling towers which include the EWK, FGS and FM ranges.
The IWC EWK & FGS cooling tower is an evaporative cooling tower enclosed in a robust, durable and compact GRP casing. EWK & FGS cooling towers have truly stood the test of time and thousands of these units are still operational after decades of reliable service.
The IWC FM range of cooling towers is a modular range of multi-fanned factory assembled cooling towers which provide high cooling capacity that are easily transported and maintained.
Non-Corroding
Designed for a long life under extreme damp and contaminated conditions, every industrial cooling tower is constructed from non-corroding materials. The shell is constructed from heavy duty GRP. All internal parts are made of PVC, 3CR12, stainless steel or polypropylene and all fasteners are grade 304 stainless steel.
Efficient Operation
All IWC cooling towers are have a counterflow-induced draught design for optimum performance. The water enters the induced draught cooling tower at the top and is evenly distributed over the fill material while the air enters through the inlets at the bottom and is discharged vertically by the fan. Various types of film and splash packing in different materials can be installed to accommodate any operating conditions.
Thank you for completing the work at site so quickly and accommodating us at short notice. Great jobs guys.

Reliability
Each IWC industrial water cooling tower is fitted with a static water distribution system with non-clogging nozzles. The exclusion of all moving parts except for the motor-fan assembly gives the towers excellent reliability with minimal maintenance.
Easy Installation
Even the large Package Cooling Towers, which are fully assembled prior to delivery, can be lifted and placed in position by a mobile crane preventing extended on-site erection periods.
Closed Circuit Cooling Towers & Evaporative Condensers
Depending on the duty required, the Closed Circuit Cooling Tower is fully compatible with any of our EWK, FGS or FM ranges.
A closed circuit cooling tower involves no contact between the air and the fluid being cooled. The cooling tower has two separate fluid circuits, one in which the fluid is recirculated on the outside of thesecond circuit, which is a bundle of tubes through which the hot water is flowing. The air drawn through this water provides cooling similar to an open cooling tower, except that the cooled water never makes direct contact with the air.
The fluid to be cooled (or gas to be condensed) flows through the tubes of a serpentine tube type heatexchanger (the closed circuit) without coming into contact with the external air stream thereby preventing dirt or pollution from entering the system. Heat is transferred from the fluid (or gas) through the tube walls to the cooling water which is sprayed continuously over the coil.
Either an axial or radial fan drives air through the cooler thereby evaporating some of the cooling water and in so doing releases the required heat into the atmosphere. The remainder of the cooling water is recirculated by means of a spray pump from the cooling tower basin to the spray nozzles.
Benefits of a closed circuit cooling tower:
- Capacity to withstand entering fluid temperatures up to 80 Degrees Celsius
- Cleaner Process fluid yields cleaner internal heat exchange surfaces
- Lower water treatment costs
- Prevents contamination of the process water
- Lower System maintenance costs
