Refurbishment & Upgrading of existing Cooling Towers
IWC has been active in the refurbishment of cooling
towers and bulk-air air coolers of all makes, types and sizes over
the past two decades. This includes the installation of fill material,
drift eliminators, spray systems and nozzles as well as fan mechanicals.
Old cooling towers can often be satisfactorily refurbished as an alternative
to the purchase of new ones.
In many old towers wood fill and drift eliminators have been replaced with more modern plastics and stainless steel. Also it is often found that the type of fill originally installed has not been well-suited to the water conditions and the existing fill has been replaced with more suitable non-clogging fill materials such as polypropylene or stainless steel splash-pack.
In many cases it has been possible to upgrade the performance of an existing cooling tower by judicious redesign of the internal components and fan system. The adjacent image shows our injection moulded polypropylene splash pack and downward low pressure sprayer found in conventional induced draft cooling towers.
IWC is the African leader in natural draft cooling tower refurbishment, having undertaken the vast majority of these projects in our region over the past 18 years. Having also developed methods to do this work online, IWC can aid in reducing downtime and production cuts that would normally be associated with this type of project.
