Hydratech manufacture the Coolflow range of specialist antifreeze, secondary refrigerants and heat transfer fluids for chillers, HVAC systems, solar panels & geothermal heat recovery systems.

A key objective since formation in 1998 has been the establishment of technical B2B partnerships with those responsible for plant design, installation and operation to ensure system optimisation. System optimisation includes;

• thermal and pumping efficiency - for maximum COP, ROI and energy savings

• corrosion, scale & biological control - for long life and reduced maintenance

• ecological assessment - to minimise human, animal and environmental impact

• fluid maintenance–monitoring of fluid and system condition to ensure efficiency


Products include monopropylene and monoethylene glycol based coolants blended with synergistic corrosion, scale and algae inhibitors.

Coolflow can be supplied premixed with deionized water as a one shot solution and is available with tracer dyes and taste denaturants at no extra charge. All products are held in stock and can be dispatched the same day.
