Scale removal is an important maintenance activity on heat exchangers and other industrial water handling equipment. Over time, calcium carbonate from hard water builds up on the surfaces of pipes and heat exchangers, reducing water flow and heat-transfer efficiency. Harsh minerals and organic acids like muriatic acid can be applied to address the problem but pose safety hazards due to high corrosivity. To achieve scale removal on a safer level, Cortec introduced EcoClean scale and rust remover HP.
EcoClean scale and rust remover HP is designed to periodically clear away scale buildup on all water-contracting equipment surfaces in a variety of industrial systems, such as heat exchangers, chillers, condensers, cooling towers, and pipes. It also removes corrosion on multiple metal types and contains corrosion inhibitors to counteract the aggressiveness of acids on metals.
Immersion in the product produces results for most substrates and often works within five minutes to an hour, depending on the amount of scale and corrosion. Light abrasion helps speed up penetration and removal of corrosion products. The application should be followed with a neutralising cleaner for further penetration. EcoClean scale and rust remover HP features higher potency and can be used multiple times if filtered and monitored for pH after use.
When using cleaning products or other chemicals, industries need to evaluate how it will affect their waste disposal. Companies today are faced with restrictions on specific chemicals such as phosphates, which contribute to nutrient pollution and algae growth on lakes. They also are required to stay within certain limits of BOD and COD or face extra fees or fines. EcoClean scale and rust remover HP features good disposal profile on both counts. Besides being free from phosphate-free, it is also considered a biodegradable industrial descaler according to product components and is a low contribute to BOD and COD in effluents.
