Product Code
As our leading product to the drinking water product range, Supreme SS is designed for high use environments such as in busy restaurants, where there is demand for large quantities of boiling water at point-of-use.

Supreme SS is a wall-mounted unit and is easy to install, it requires only a cold water supply and mains electrical connection. The unit has a simple 'ready' indicator to confirm when ready for use and has many innovative features such as an integral electronic water conditioner to reduce scaling and a lockable heavy duty tap for added safety.

There are four larger capacities (10, 15, 25 or 40 Litres) of Supreme SS units to choose from, providing up to an impressive 560 cups of boiling water per hour or 240 cups immediately, one after the other. The stainless steel casing is not only a stylish feature; it is fingerprint resistant and is perfect for environments where hygiene integrity is important.

Biomaster® is an antibacterial silver-ion agent that is added to the Supreme on-wall water dispensers, to prevent the growth of bacteria, which is paramount in hygiene-critical environments.

It guarantees fast, effective antimicrobial protection for the effective lifetime of the Supreme, helps to keep its surfaces clean and hygienic and reduces the risk of cross-contamination, aiding HTM 04-01 compliance.
