The Guardian Pulse Plus is a smart, proportional constant dosing system built for the precise application of EndoSan. With pulse step-up and step-down technology, it automatically adjusts dosing in line with your water meter signals — ensuring accuracy every time.
A built-in traffic-light indicator makes it easy to see when EndoSan levels are running low, while all components, including lance and bund, are pre-assembled and rigorously tested before delivery.
Simple to install and use, this ‘plug and play’ system takes the hassle out of water treatment, saving you both time and operating costs.
Your package includes full installation, calibration and commissioning by a qualified engineer, an additional site visit within 12 months, and the reassurance of a two-year extended warranty.
Constant dosing – once clean, stay clean
We recommend a full system disinfection during dry dock to remove existing biofilm and contamination in vessel water systems. The challenge is that biofilms can re-form quickly, leaving untreated systems at risk of re-contamination.
With EndoSan, low-level continuous dosing provides ongoing protection in a controlled, automated way, keeping water systems safe and compliant at all times.
