Online Cleaning
Non-disruptive cleaning for continuous operations
Online cleaning allows critical systems to remain operational while contaminants are safely removed. This facilitates consistent output, improves asset reliability and ensures our customers can meet production targets while preventing unnecessary shutdowns and lost productivity.
InterGroup’s chemists and technical experts work with our customers to develop safe, effective online cleaning protocols. We draw on decades of on-site experience and industry-leading techniques and technology to maintain operations while meeting all regulatory and safety standards.
Using customised low-impact techniques and tailored cleaning agents, we perform cleaning of systems, tanks, lines and exchangers without interrupting production. This includes:
- Non-invasive flushing and chemical circulation through closed-loop systems for internal tank and pipe cleaning
- Application of foam or gel cleaning agents that cling to surfaces, allowing longer contact time to break down stubborn residues
- Precision spray systems such as rotating spray balls or low-pressure nozzles that deliver even, controlled coverage inside sensitive assets
- Side-stream filtration to continuously remove loosened contaminants during the cleaning process without interrupting system operation
- Heat-assisted or chemically enhanced flushing when required to accelerate cleaning in high-fouling environments
We adapt our methods to each client’s operational parameters, ensuring residue, scale, or biofilm is removed effectively while sensitive systems – such as heat exchangers, process vessels, and pipelines – continue to run safely and efficiently. Our team works closely with plant operators and HSE managers to align cleaning protocols with site-specific risk, product handling and compliance requirements.
Benefits to our customers
- Zero unplanned downtime: Online cleaning enables ongoing production while cleaning is performed, reducing the need for costly shutdowns and maintaining delivery timelines.
- Lower maintenance costs: By addressing fouling and residue build-up proactively, our customers avoid costly repairs, asset degradation and emergency callouts.
- Consistent system performance: Clean systems operate closer to design efficiency, resulting in better thermal transfer, improved product quality and reduced strain on equipment.
- Enhanced safety and compliance: Cleaning can be done without exposing workers to hot work or high-risk environments, supporting safer practices and helping meet site-specific compliance obligations.
