Thermal and evaporative system management services

Legionnaires’ disease outbreaks

• Evaporative cooling systems provide an ideal environment for Legionella bacteria to thrive, especially in stagnant or untreated water.
• Legionella-contaminated aerosols can spread through air conditioning and cooling tower drift, putting employees, visitors, and the public at risk.
• Non-compliance with ACoP L8 and HSG274 can result in severe legal penalties and reputational damage.

Reduced energy efficiency

• Scale and biofilm buildup on heat exchangers and cooling tower components reduce thermal transfer efficiency, forcing systems to work harder.
• Higher energy consumption leads to increased operational costs and greater environmental impact.

Compliance failures

• Businesses must adhere to HSG274, ACoP L8, and BG50 guidelines for safe operation.
• Non-compliance with water hygiene regulations can lead to legal action, fines, and potential shutdowns.
• Inadequate record-keeping and monitoring can result in failed audits and regulatory scrutiny.

Increased operational costs

• Unplanned maintenance, repairs, and system downtime from corrosion, scale, or biofouling lead to expensive emergency interventions.
• Poor water treatment can shorten equipment lifespan, requiring premature replacements.
• Inefficient systems drive higher water and chemical usage costs.

Proactive management is essential

To mitigate these risks, businesses must implement:

• Ongoing monitoring – Continuous water quality checks to detect early signs of contamination or scaling.
• Effective water treatment – Preventative dosing, filtration, and scale/corrosion inhibitors.
• Regulatory compliance adherence – Regular risk assessments and logbook maintenance.
