Classeq WS-HC10 Automatic Hot Feed External Water Softener

The Classeq WS-HC10 is an external water softener designed to work alongside Classeq undercounter and pass-through commercial warewashers. It connects to a hot-feed water supply and uses an automatic brine-tank regeneration process to remove the hardness minerals that cause limescale build-up inside the machine. It is a standalone unit, fitted externally, and handles softening before water enters the washer.

In busy commercial kitchens, limescale is one of the most consistent causes of warewasher underperformance. It accumulates on heating elements, spray arms and wash chamber walls, reducing wash quality, increasing energy consumption and — over time — leading to costly breakdowns. A properly installed softener addresses this at the source rather than relying on rinse-aid or descaling chemicals alone. The WS-HC10's automatic regeneration is timed to run during quieter periods, so the softener is ready when service demand is at its highest without interrupting the wash cycle.

Practical advantages of running this unit alongside a Classeq washer include:

• Reduced limescale accumulation on heating elements and spray arms, helping to maintain wash performance over time
• Lower descaling frequency, which reduces chemical costs and labour time
• More consistent rinse results, particularly in hard-water areas
• Automatic regeneration that avoids service interruptions during peak periods
• Compatibility across the Classeq undercounter and pass-through range

Installation requires a connection to a hot-feed water supply, so it is worth confirming your existing plumbing layout before ordering. The unit will need a dedicated position close to the warewasher — the dimensions are reasonably compact but there should be adequate clearance for routine maintenance access. Salt replenishment for the brine tank is an ongoing operational requirement; how frequently this is needed will depend on local water hardness and machine usage volumes. Sites in particularly hard-water regions may find regeneration cycles are more frequent.

The WS-HC10 is well suited to small and medium-sized operations running Classeq undercounter or pass-through machines where water hardness is a known issue. It is particularly relevant for sites in hard or very hard water areas, where running a warewasher without any softening provision will typically lead to noticeable problems within months. For higher-volume sites or situations involving multiple machines, it is worth discussing whether a more robust softening solution would be more appropriate.

If you are unsure whether this unit is the right fit for your water supply, machine type or site layout, we are happy to talk it through before you place an order.
