Supporting HVAC Efficiency & Operational Performance in Data Centre Environments

Data centres are critical to the modern digital economy, supporting everything from cloud computing and AI infrastructure to financial systems and global communications. As demand for data processing increases, so does the need for efficient and reliable cooling systems capable of maintaining stable operating conditions.

Cooling infrastructure accounts for a significant proportion of data centre energy consumption. Maintaining the efficiency of Air Handling Units (AHUs) and cooling coils is therefore essential not only for operational performance, but also for energy management, sustainability targets and long-term cost control.

Biozone Scientific’s Coilcare Energy solution has been developed to support HVAC efficiency and help maintain cooling coil performance in commercial environments, including data centres.

The Challenge of Cooling Efficiency in Data Centres

Data centres generate substantial heat loads, requiring continuous airflow and cooling to support stable equipment operation. Over time, cooling coils within AHUs can accumulate biofilm, dust and organic build-up, reducing thermal transfer efficiency and restricting airflow.

As coil performance declines, HVAC systems often require additional energy to maintain the desired cooling output. This can contribute to:

  • Increased HVAC electricity consumption
  • Reduced cooling efficiency
  • Higher operational and maintenance costs
  • Increased strain on HVAC infrastructure
  • Additional downtime associated with manual cleaning processes

Traditional coil cleaning methods can also be disruptive, labour intensive and dependent on chemical cleaning agents, making long-term maintenance more challenging in mission-critical environments such as data centres.

Why Cooling Coil Performance Matters

Cooling coils play a central role in regulating airflow temperature and maintaining environmental stability within data centre environments. Reduced coil efficiency can impact thermal transfer performance, forcing HVAC systems to work harder to maintain operational conditions.

Maintaining coil condition can therefore support both cooling performance and operational efficiency across the wider HVAC system.

How Coil Build-Up Affects HVAC Efficiency

Over time, organic build-up on cooling coils can restrict airflow and reduce heat exchange performance. As efficiency decreases, HVAC systems may require increased energy usage to maintain cooling output.

This additional strain can contribute to:

  • Increased operating costs
  • Reduced airflow efficiency
  • Greater maintenance requirements
  • Additional system pressure across HVAC infrastructure

The Coilcare Energy Solution

Biozone Scientific developed Coilcare Energy to support the ongoing performance of HVAC cooling coils in commercial environments.

The system utilises 254nm UV-C technology within AHUs to continuously irradiate cooling coil surfaces, helping to maintain cleaner coil conditions and support airflow efficiency over time.

By operating continuously, Coilcare Energy helps organisations:

  • Support HVAC operational efficiency
  • Maintain cooling coil performance
  • Reduce reliance on reactive maintenance schedules
  • Minimise manual cleaning requirements
  • Reduce downtime associated with coil cleaning

Coilcare Energy systems are designed for retrofit installation and can be integrated into existing HVAC infrastructure with minimal disruption.

How Coilcare Energy Supports HVAC Performance

Coilcare Energy operates continuously within the AHU environment to help maintain cooling coil condition and support airflow performance.

By helping maintain cleaner coil surfaces over time, the system can contribute to improved HVAC operational efficiency and reduced performance degradation.

UV-C Technology Within Commercial HVAC Systems

The system uses 254nm UV-C technology positioned within AHUs to irradiate cooling coil surfaces during operation. This supports ongoing coil maintenance without requiring regular shutdowns or disruptive manual cleaning procedures.

Retrofit Installation for Existing AHUs

Coilcare Energy systems are typically installed as retrofit solutions, allowing integration into existing HVAC infrastructure with limited operational disruption.

Biozone Scientific provides assessment tools to help determine the optimal lamp configuration for individual AHU and coil systems.

Operational Benefits for Data Centres

Supporting HVAC Energy Efficiency

Cooling coil condition can have a direct impact on HVAC performance and electricity usage. By helping maintain cleaner coil surfaces and supporting airflow efficiency, Coilcare Energy can contribute to reduced HVAC energy demand in commercial environments.

In some applications, organisations have reported HVAC electricity savings of up to 24%, helping reduce operational energy expenditure and support sustainability initiatives.


Maintaining Cooling Capacity & Airflow Performance

Efficient airflow and thermal transfer are essential in data centre environments where stable temperatures are critical to operational continuity.

By supporting cleaner coil conditions, Coilcare Energy helps AHUs operate closer to intended performance specifications, contributing to:

  • More consistent airflow
  • Improved thermal transfer efficiency
  • Reduced strain on cooling infrastructure
  • Enhanced operational stability


Supporting Sustainability & ESG Objectives

Reducing energy demand within HVAC systems can also support broader environmental and sustainability objectives.

Additional operational benefits may include:

  • Reduced reliance on chemical cleaning agents
  • Lower maintenance-related travel requirements
  • Reduced maintenance disruption
  • Support for operational carbon reduction initiatives

Coilcare Energy aligns with wider industry efforts to improve energy efficiency and operational sustainability within commercial facilities.


Reducing Maintenance Disruption

Traditional coil cleaning methods often require downtime, manual labour and chemical cleaning products.

By supporting ongoing coil maintenance during operation, Coilcare Energy can help reduce maintenance disruption and improve operational continuity within commercial environments.

Installation & Maintenance Considerations

AHU Assessment & System Configuration

Coilcare Energy installations are typically retrofit solutions designed for integration into existing AHU infrastructure.

Biozone Scientific provides proprietary assessment tools to help determine the appropriate lamp configuration for individual coil systems and operating environments.


Lamp Replacement & Ongoing Operation

For ongoing operational continuity, lamps are typically replaced every 18–24 months depending on system usage and environmental conditions.

Biozone Scientific also recommends maintaining a small stock of replacement lamps onsite to support uninterrupted operation where required.

Conclusion

As data centres continue to grow in scale and operational demand, improving HVAC efficiency remains a key priority for facilities and operations teams.

Biozone Scientific’s Coilcare Energy solution supports cooling coil performance, HVAC operational efficiency and energy management within commercial environments. By helping maintain cleaner coil conditions and supporting airflow efficiency, Coilcare Energy can contribute to improved operational performance, reduced maintenance disruption and long-term sustainability objectives.
