GARDUS is a flexible, robust, leak-detectable dual containment hose system that is utilised in the water treatment industry for its safety and cost benefits. GARDUS conveys aggressive and high-concentration chemicals safely, eliminating the potential risk to personnel and the environment by containing leaks. Any potentially leaked liquid stays between the inner and outer hose, and with no air gap, wastage is minimised. In addition, with no leakage into the surrounding area, there is no potential risk to health or environment, or disposal of harmful chemicals from a catch pot.

GARDUS is suitable for a broad range of chemical dosing and water treatment applications for potable water, waste water and industrial water processing in the water treatment, chemical, mining, pharmaceutical, and manufacturing sectors in both new and retrofit installations.

What sets the innovative GARDUS system ahead of the market, is the unique GARDUS Sentinel leak alarm and alert function. In the unlikely event of a leak, the system will immediately shut down the pump and raise the alarm to notify plant controllers via control panels or sms alerts.
