Through our knowledge and experience of local conditions, we are able to provide flexible, tailored solutions to suit any project, at home or abroad. Our products and services are easily exported to any country.

Our extensive product range includes package cooling towers, large field erected mechanical and natural draught cooling towers, as well as their refurbishment. We also supply plate heat exchangers manufactured by Sondex to sub-Saharan Africa. Our service offering includes the design, manufacture and development of cooling systems, cooling towers and equipment, repairs and refurbishment, spares and other associated services. With heavyweight clients such as Eskom, Sasol, ArcelorMittal, Foskor, Impala Platinum, Anglo Platinum. It is safe to say that we set the benchmark in the industry.

We are a long standing member of the CTI, Cooling Technology Institute, based in the US. This association has as its members both constructors as well as end users of cooling towers.

Our company focus is based on the high quality (ISO 9001-2008 accredited company) and excellent service standards, while always maintaining a competitive price structure. Our portfolio of projects illustrates our activity across the SADC region; we have provided solutions in Zambia, Tunisia, Ghana, Mauritius and Swaziland.

Comprehensive cooling solutions

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
  • Timber
  • 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

Plate heat exchangers

Our plate heat exchangers are supplied by SONDEX, a leading Danish company specialising in the development and production of plate heat exchangers and distillers. The range offers the optimal technical solution for any possible task through a numerous connection sizes. The freshwater distiller range covers capacities from 1t-100t per 24 hours.

The range includes:

  • Free flow plates
  • Semi-welded plates
  • Sonder safe plates
  • Brazen plate heat exchangers
  • All welded plate and shell exchangers

Glass-reinforced plastics solutions

We offer various GRP related design, manufacturing and installation products:

  • Freestanding GRP cells and GRP liners for electrolytic and electro winning metal refineries
  • Scrubbers, cooling towers, process vessels and GRP storage tanks
  • Piping, fittings and ductings
  • GRP overwrapped thermoplastics & fluoroplastics
  • Chimney stacks
  • Underground storage tanks for petroleum storage
  • Firewater mains
  • GRP corrosion resistant linings

We offer the following GRP services:

  • The erection of plant and equipment
  • Onsite GRP repairs and maintenance
  • EPC projects

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).

Noor Ouarzazate Solar Complex

The Noor Ouarzazate Solar Complex is a 580MW power plant located 10km north-east of the city of Ouarzazate, Morocco.
