HVAC Chilled & Heating Water Closed Loop Management

Advanced closed loop filtration systems

Chilled and heating water loops are critical to HVAC and process system performance, ensuring consistent temperature control for both occupant comfort and sensitive equipment. Over time, these closed systems face risks including:
  • Corrosion and scale buildup
  • Microbiological growth and biofilm
  • Fouling of pipework and heat exchangers
If ignored, these issues cut efficiency, raise energy costs, and cause early equipment failure—resulting in costly repairs, downtime, and non-compliance.

The Filter Pot Systems

Flowio side-stream filtration units are purpose-built for chilled and heating water loops, ensuring high-performance closed-loop water quality management. Some of our key features:

  • Rare earth magnetic separation for iron oxide (magnetite)
  • Silver-ion antimicrobial cartridge filtration (0.5 micron)
  • Integrated air separation to reduce oxygen and corrosion
  • Built-in chemical dosing points
  • Automatic air vents for added protection

The experts in closed-loop water systems

FLOWIO Group provides expert servicing through Australian Water Treatment (AWT). The AWT team specialises in managing and optimising chilled and heating water loops, supported by in-house expertise and a deep understanding of closed-loop system dynamics.

Key services include:

  • Pre-commissioning flushing and cleaning to BSRIA standards, guaranteeing smooth system handover and long-term performance
  • Corrosion control and precision chemical dosing
  • Microbiological management and biofilm prevention
  • Advanced diagnostics and thermal performance optimisation

As part of our unique offering, we utilise a proprietary non-flush cleaner with a filtration-based method – a sustainable breakthrough in pre-commissioning cleaning. Traditional methods waste enormous volumes of water (a 100,000-litre system typically wastes 500,000 litres during flushing). Our approach delivers the same water quality standards and asset protection without the waste, saving half a million litres on a single system while lowering costs and environmental impact.

With industry-leading tools and real-time remote monitoring, our technicians safeguard water chemistry, spot risks early, and act decisively. We tailor programs for healthcare, commercial, and industrial facilities – ensuring reliable operation, energy efficiency, and full compliance.
