Why Traditional Chiller Tube Cleaning Methods Are Holding You Back

The Downside of Traditional HVAC Maintenance

Are Your HVAC Cleaning Methods Costing You More Than You Think?

In commercial buildings, industrial facilities, and data centers, HVAC efficiency is crucial for energy savings and operational reliability. However, many businesses still rely on outdated cleaning methods like manual tube brushing and chemical descaling, both of which come with major drawbacks:

❌ High Maintenance Costs ❌ System Downtime ❌ Temporary Solutions ❌ Environmental Impact

As energy prices rise and sustainability becomes a key focus, businesses must rethink HVAC maintenance strategies. This article explores why traditional cleaning methods are holding you back and how Automatic Tube Cleaning Systems (ATCS) can revolutionize HVAC performance.

Understanding Traditional HVAC Cleaning Methods

1. Manual Tube Cleaning: The Costly, Labour-Intensive Approach

Manual cleaning involves mechanical tube brushing and high-pressure flushing to remove scale and debris. While effective in the short term, this approach has significant downsides:

• ❌ Requires chiller shutdown, leading to productivity losses.
• ❌ Labour-intensive and expensive, increasing operational costs.
• ❌ Limited effectiveness, as fouling begins forming immediately after cleaning.

2. Chemical Descaling: Short-Term Fix, Long-Term Damage

Chemical descaling uses acidic solutions to dissolve mineral deposits and biofilm inside tubes. However:

• ❌ Harsh chemicals corrode tube walls, reducing equipment lifespan.
• ❌ Environmental concerns due to chemical waste disposal.
• ❌ Frequent re-application needed, as fouling reoccurs over time.

3. Scheduled Cleaning Cycles: Reactive, Not Preventive

Many facilities follow fixed maintenance schedules, but the problem is:

• ❌ Fouling occurs between cleanings, decreasing efficiency.
• ❌ Energy waste accumulates, leading to higher electricity bills.
• ❌ Unexpected breakdowns still happen, requiring emergency repairs.

Automated Brush System

The brush system is a cleaning mechanism that removes fouling from tubes using brushes

• ❌Diverter Valve Maintenance: The diverter valve is a critical component in the brush system, and it has moving parts prone to maintenance.
• ❌Increased Pressure Drop: The four-way diverter valve, combined with the internally housed brushes, results in a higher pressure drop than a ball system.

🔍 Fact: A thin 0.6mm layer of fouling can decrease heat exchanger efficiency by up to 40%, significantly impacting energy consumption and operating costs.

Industries That Benefit Most from ATCS

🏢 Commercial Buildings – Consistent cooling with minimal maintenance. 🏥 Hospitals – Reliable HVAC for patient safety and medical equipment. 💾 Data Centres – Prevents overheating and ensures uninterrupted operations. 🏭 Manufacturing Plants – Maintains stable production temperatures. ⚗️ Chemical /Pharmaceutical –Avoiding costly shutdowns & supporting green initiatives

🔍 Case Study: A leading Data centre reduced its chiller energy costs by 18% after installing ATCS, with an ROI achieved in just 14 months.
