We offer various cooling tower solutions tailor made to our clients requirements, whether it be for a clean water e.g. HVAC or dirty and aggressive slurry cooling applications, IWC has a suitable solution:
Package cooling towers
Our package cooling towers are constructed from non-corroding materials design for long under extreme conditions. The shell is constructed from heavy duty fibreglass with structural members from 3CR12.
Internal components are either, PVC, 3CR12, stainless steel or other plastic materials, specific to client application and all fasteners are grade 304 stainless steel. The towers are manufactured in our works and transported to site complete and ready for installation.
Field-erected mechanical draught cooling towers
IWC designs, supplies and erects large field erected cooling towers in a variety of bespoke solutions, materials of construction are chosen to suit site conditions and to date IWC has successfully supplied cooling towers constructed from:
- Cast-in-place steel-reinforced concrete
- Structural steel
- Pultruded fibreglass sections
- Polymer-lined fibreglass panels;
Cooling tower refurbishment
We are the South African leader in the refurbishment of natural draught cooling towers, have undertaken the cast majority of these projects in our region over the past 24 years. We have also developed methods to do this work on-line thereby reducing down time and production cuts that would normally be associated with this type of project.
We offer various services for cooling towers:
- Turnkey cooling water installations
- Water treatment equipment – filters and dosing equipment
- Testing and evaluation of cooling towers
- Parts and accessories for all cooling towers

Products and Services
Plate Heat Exchanger Maintenance
The conventional plate heat exchanger was first developed in the 1930's. The PHE of today consists of a number of thin, corrugated plates that have rubber gaskets separating them or are welded together (or a combination of these).
Evaporative Water Cooling for Power Applications
Industrial Water Cooling specialises in evaporative water cooling products and services for numerous applications in the power sector.
