Case Study - Cooling Towers - BAC Sumps
Project Brief: The Internal Relining of 4 No. BAC Cooling Tower Sumps
System Specification: Solvent Free Polyurethane
Completion Date: 5th January 2010
COVAC Contract Ref: 913
If left untreated, the internal steel substrates would be endangered with a continued risk from progressive corrosion, clogging of the filters and micro aquatic bacterial growth including Legionella, Pseudomonas and Biofilm; this can lead to further deterioration in the towers surface structure, performance and contamination of the down services with the supply and dispersion of unhygienic and potentially harmful water.
The internal surfaces of the sumps having been drained of water prior to any work commencing.
The internal substrates after being prepared by COVAC Operatives in accordance with ISO 8501-1:2007, utilizing mechanical power tools and manual tools.
The substrates having received the1st full coat of Polyurethane coating (cream) Solvent Free Polyurethane, by means of brush and roller.
All intricate areas were again ‘stripe coated’ for a second time. The following photographs show the final application of the 2nd coat of Solvent Free Polyurethane (grey).
