EWC 20 Litre Manual Water Softener

The EWC 20 Litre Manual Water Softener is a compact, inline softening unit designed to reduce limescale build-up in commercial dishwashers operating in hard or very hard water areas. It works by exchanging calcium and magnesium ions in the mains supply for sodium ions, delivering softened water to the machine before it enters the wash cycle. No electrical connection is required — the unit operates purely on water pressure, making installation straightforward in most under-counter or pass-through dishwasher setups.

In practical terms, hard water is one of the most common causes of premature dishwasher deterioration in commercial kitchens. Scale accumulates on heating elements, spray arms, and pump components, reducing efficiency and increasing running costs over time. A correctly specified inline softener helps protect that investment and maintain wash quality consistently across a busy service period.

Key operational advantages include:

• Protects dishwasher heating elements and spray arms from limescale damage
• Helps maintain consistent wash and rinse performance over time
• No electrical supply required — simple installation alongside existing pipework
• Stainless steel construction suited to the demands of a commercial kitchen environment
• Flexible hose fitting allows for straightforward connection in tight spaces

The unit requires periodic regeneration using salt — the resin bed that captures hardness minerals becomes exhausted over time and needs flushing through to restore capacity. Regeneration frequency will depend on your local water hardness and the volume of water your machine processes. It is worth noting that this unit is intended for dishwashers and glasswashers only. It should not be used on equipment that produces a consumable product — ice machines, coffee machines, and combi ovens require a different type of filtration treatment and this softener is not appropriate for those applications.

This unit is well suited to smaller commercial operations running a single pass-through dishwasher in a hard water area. For sites with higher throughput, more frequent wash cycles, or very high water hardness, a higher-capacity softener may be a more practical long-term choice.
