Recirculating Cooling Towers


Maximising Performance, Protecting the Environment

Recirculating Cooling Towers

Chlorine Dioxide solutions from Scotmas offer operators a unique opportunity to achieve cost savings while protecting the environment

Quick Fact

Annual savings of £1,600,000 and a reduction in carbon emissions of 9,000 tonnes were achieved, whilst operating on a complex site of Special Scientific Interest

Cooling tower operators are faced with increasing pressure to ensure safety from bacterial infections such as Legionella, whilst also being under pressure to reduce operating costs.

Biofilm build up on condenser plates and cooling tower packs acts both as an insulating layer, slowing down heat transfer, reducing water flow and increasing pumping costs, as well as being a harbour for dangerous legionella bacteria which live alongside scale, pseudomonas and other bacteria in a slimy layer found on plate surfaces and pipework.

As well as the risk from Legionella, biofilm also poses a threat to asset integrity. Bacteria at the base layer of the film can create an anaerobic, corrosive environment and can feed from plastic and metal structures, passing on nutrients to other nearby bacteria. This phenomena, called biocorrosion regularly leads to pack collapses and poor water flow throughout the tower, requiring expensive and disruptive pack changes and increased energy costs to pump water around the tower.

Scotmas Chlorine Dioxide solutions for cooling towers are designed to minimise these risks. Our online, fully automatic dosing systems add a controlled amount of chlorine dioxide sufficient to remove biofilm leading, keeping heat transfer surfaces clean and free of biofilm. Frictional losses and pumping costs are reduced and there are significant improvements in ∆T.

Applied by your water treatment professional as part of a wider program of cooling tower hygiene, Scotmas Chlorine Dioxide solutions can be used in the smallest forced draft towers and wet chillers, typically used in the injection moulding and plastics extrusion industry, through to the largest industrial cooling networks such as found in power stations and petrochemical refineries.

Project Engineerign Specialists for CIO2

Scotmas offer a range of chlorine dioxide generators in containerised solutions to help support your water purification or water disinfection project. Choosing a containerised system means that the Chlorine Dioxide Generator can be built and fully tested to the highest of standards in our factory prior to delivery on-site. On delivery, a containerised ClO2 system is installed for minimum downtime and on-site disruption.
