HM Range

The HydroFLOW® HM Range is designed for marine and offshore environments, tackling limescale and biofouling in seawater and freshwater systems. It offers durable, saltwater-ready performance to protect heat exchangers, desalination plants and utility lines.

The HM Range is built for ships, ports and offshore platforms where seawater and variable quality makeup water can drive scale, slime and biofouling. HydroFLOW® treatment helps keep plate coolers, heat exchangers, desalination pretreatment, ballast and utility lines cleaner for longer by discouraging adhesion of minerals and biofilm. The technology works with existing materials and can be added without pipe cutting, supporting planned maintenance windows. By aiding heat transfer and filtration and by reducing manual cleaning, HM helps operators pursue steadier output and lower whole-life costs across marine assets.

Features

  • Up to 200 mm OD (≈ 7.9”)

  • Suitable for industrial plants, boilers, heat exchangers, and cooling towers

  • Requires hardwired installation. No pipe cutting needed.

Marine-Grade Build

The HM unit is DNV-certified, confirming it meets the rigorous standards required for marine and offshore use. This ensures reliability, safety, and compliance for shipboard and desalination applications.

Protects Your Applicances

Controls Biofouling

Helps prevent the build-up of biofilm and algae in seawater systems, pipework, and heat exchangers. This improves flow efficiency and reduces cleaning frequency.

Kinder to Skin and Hair

Protects Desalination Plants

Helps maintain desalination performance by limiting scale and fouling on membranes and pipe surfaces, extending service life and lowering operating costs.

Keep Healthy Minerals in Water

Non-Invasive Installation

Clamps easily around existing pipework with no cutting or downtime, making installation straightforward and suitable for a wide range of marine piping.

Protects Your Applicances

Cuts Maintenance Costs

With less scale and fouling to manage, plant operators spend less time and money on cleaning and descaling. This means fewer shutdowns, lower chemical use, and more consistent output across your systems.
