EWC Automatic Cold Water Softener

SKU: CS-5, CS-10, CS-16HX, CS-23, CS-30

From £357.00(£428.40 inc VAT)

The EWC Automatic Cold Water Softener is a timer-controlled inline unit designed to treat incoming cold water before it reaches connected warewashing equipment. It works by removing the dissolved minerals responsible for limescale, protecting heating elements, wash arms, and internal pipework from the gradual build-up that causes performance to decline and shortens equipment life.

In hard water areas, limescale is one of the most common causes of avoidable equipment damage in commercial kitchens. Heating elements scale over and lose efficiency, wash arms become progressively restricted, and service intervals shorten. Treating water quality at source — before it enters the machine — is consistently more effective than descaling after the fact, and for operations running warewashing equipment daily, the impact on running costs and service frequency adds up over time.

Running softened water through your warewashing equipment brings several practical advantages:

Reduces scale accumulation on heating elements, extending their working life
Supports more consistent cleaning and drying results from dishwashers and glasswashers
Lowers the frequency and cost of descaling treatments and unplanned service callouts
Helps protect manufacturer warranties, which are commonly voided by limescale damage
Can reduce ongoing consumption of rinse aid and detergent

The unit regenerates automatically on a timer cycle and requires a supply of block salt along with routine checks to maintain correct operation. Installation is a straightforward inline connection on the cold water feed ahead of the protected equipment — a job for a qualified plumber. When planning the installation, allow adequate clearance around the unit for salt top-ups and routine maintenance access.

This softener is well suited to cafés, pubs, restaurants, and similar small to medium-sized operations running a single glasswasher or dishwasher in a hard water area. Sites with multiple machines or significantly higher daily throughput should consider a higher-capacity unit to avoid frequent regeneration cycles that could interrupt supply.

If you are unsure whether your water hardness warrants a softener, or whether this capacity is the right fit for your setup, our team is happy to talk it through before you commit.

EWC

EWC Automatic Hot Water Softener for Warewashing

SKU: HS-10, HS-16HX, HS-23, HS-30

From £602.00(£722.40 inc VAT)

The EWC Automatic Hot Water Softener is a timer-controlled inline unit designed to treat the hot water supply feeding commercial dishwashers, glasswashers, and similar warewashing equipment. It works by exchanging the calcium and magnesium ions responsible for water hardness with sodium ions, delivering consistently softened water directly to connected appliances. This deals with limescale at source, rather than relying on rinse aid and chemical dosing to manage the effects after the fact.

Across the majority of UK hard water areas, untreated mains water causes progressive scale accumulation inside heating elements, wash arms, boilers, and internal pipework. Left unaddressed, this reduces heating efficiency, restricts water flow, produces uneven wash results, and accelerates wear on components that are costly to replace. Fitting a softener on the hot feed is one of the more straightforward protective measures an operator can take — and one that tends to pay back over time through reduced servicing and longer equipment life.

From a day-to-day standpoint, softened water brings a noticeable improvement in results, particularly on glassware where hard water leaves spotting and film that takes additional chemistry to counteract. The practical advantages include:

Cleaner, spot-free results on glassware and crockery with reduced chemical reliance
Lower risk of spray arm and element blockages causing unplanned engineer callouts
Timer-controlled regeneration scheduled overnight, well away from service periods
Supports manufacturer warranty compliance — many require adequate water treatment
Reduced servicing costs over the working life of connected warewashing equipment

The unit sits inline on the hot water feed to the connected machine and requires a salt supply for regeneration. It is worth establishing your incoming water hardness before committing to a specification — in areas with moderate hardness, the operational benefit is real but more gradual than in very hard water regions such as London and the South East. Sites running multiple warewashing machines simultaneously, or operating at high volume throughout the day, may find it worth discussing whether a higher-capacity unit or a more centralised treatment approach is better suited to the demand.

If you are weighing up whether your site warrants a softener, or have questions about water hardness in your area and where to position the unit, the team is happy to talk it through before you commit.

EWC 8 Litre Manual Water Softener product image

EWC

EWC 8 Litre Manual Water Softener for Glasswashers

SKU: WS8

£102.00(£122.40 inc VAT)

The EWC 8 Litre Manual Water Softener is a compact inline unit designed to protect small commercial glasswashers and undercounter dishwashers from the effects of hard water. It works by passing the incoming cold water supply through a resin bed, which exchanges calcium and magnesium ions for sodium — delivering softened water to the machine with no electrical connection required.

Hard water is one of the most consistent causes of premature wear in warewashing equipment. Scale accumulates on heating elements, spray arms, and internal pipework over time, gradually degrading wash quality and shortening machine life. In medium-to-hard water areas, the damage can be measurable within months. Fitting an inline softener on the cold water feed is one of the most straightforward protective measures an operator can take.

Protects heating elements and spray arms from limescale accumulation
Helps maintain consistent wash and rinse results over time
No electrical supply required — fits directly on the cold water feed
Stainless steel construction suited to a commercial environment
Manually regenerated with salt, keeping ongoing running costs low

The unit connects via the fitted flexible hose to the machine's cold water inlet. Regeneration is a manual process using salt, carried out once the resin capacity is exhausted. How often that's needed depends on local water hardness — operators in very hard water areas should expect to regenerate more frequently. This unit is not suitable for ice machines, coffee equipment, combi ovens, or any application where the water forms part of a consumable product.

This softener is well suited to small single-phase glasswashers or undercounter dishwashers in lower-volume settings such as small bars, cafés, or staff canteens. For higher-throughput sites, larger machines, or areas with severe water hardness, a higher-capacity unit is likely to be the more practical long-term choice.

If you're unsure whether this unit is the right fit for your machine or your local water conditions, the team is happy to talk it through before you commit to an order.

EWC 12 Litre Manual Water Softener product image

EWC

EWC 12 Litre Manual Water Softener for Dishwashers

SKU: WS12

£120.00(£144.00 inc VAT)

The EWC 12 Litre Manual Water Softener is a compact inline unit designed to reduce water hardness in the supply line feeding a commercial dishwasher or glasswasher. It works by passing incoming water through a resin bed that exchanges calcium and magnesium ions — the minerals responsible for limescale — for sodium ions, delivering softened water to the machine without requiring any electrical connection.

Hard water is one of the most consistent causes of premature failure in commercial warewashing equipment. Limescale accumulates progressively on heating elements, spray arms, and wash chamber surfaces, reducing cleaning effectiveness, increasing energy consumption, and shortening equipment life. Fitting a softener upstream of the machine addresses the problem at source rather than managing the consequences later.

For day-to-day operation, this unit offers a straightforward set of practical advantages:

No electrical connection required — purely plumbed inline installation
Regenerates manually using standard salt — no automated controls to maintain or calibrate
Stainless steel construction suited to commercial kitchen environments
Flexible hose fitting included to ease connection to existing pipework
Compact footprint suits installations where under-sink space is limited

Installation requires the unit to be plumbed into the cold water supply line ahead of the machine. Regeneration is a manual process — the operator flushes the resin bed with salt solution at intervals determined by local water hardness and daily throughput. It is worth noting that this softener is not appropriate for equipment producing a consumable output, such as ice machines, coffee equipment, or combi ovens with steam injection. Those applications require a separately filtered or treated supply.

This unit is well suited to small cafés, bars, pubs, and hospitality operations running a single glasswasher or compact dishwasher in a hard water area. Sites with higher-throughput machines, harder water, or multiple units to protect should consider a larger-capacity softener to match the demand.

If you are unsure whether this unit is the right match for your machine or your local water conditions, the team is happy to help you work it out before you commit.

EWC 16 Litre Manual Water Softener product image

EWC

EWC 16 Litre Manual Water Softener for Dishwashers

SKU: WS16

£122.00(£146.40 inc VAT)

The EWC 16 Litre Manual Water Softener is an inline water treatment unit designed to protect commercial dishwashers and glasswashers from the effects of hard water. It connects directly to the cold water feed supplying the machine and passes incoming mains water through a resin bed, which exchanges hardness minerals — primarily calcium and magnesium — for sodium ions. The result is softened water delivered to the machine on an ongoing basis, with no electrical connection required. Regeneration is handled manually using standard dishwasher salt.

Hard water is one of the more consistent causes of premature wear in commercial warewashing equipment. Limescale builds progressively on heating elements, spray arms, and internal pipework, reducing wash performance over time, drawing more energy, and compressing the intervals between required servicing. Treating the water before it reaches the machine is a straightforward way to slow that process and maintain reliable results across the machine's working life.

From an operational standpoint, the practical advantages include:

Reduces limescale accumulation on heating elements, helping sustain consistent wash temperatures
Extends intervals between descaling treatments, easing routine maintenance demands
Helps protect internal components and pipework over time
No power supply required — simple to fit and operate
Flexible hose connection aids installation in tight under-counter spaces

Because regeneration is a manual process, kitchen staff will need to monitor usage and treat the resin bed with salt at appropriate intervals. It is worth factoring this into your regular cleaning schedule. The unit is sized for a single dishwasher or glasswasher and is not intended for equipment that produces consumable output, such as ice makers or coffee machines.

This softener is well suited to pubs, cafes, and smaller restaurant operations running a single commercial dishwasher or glasswasher in a hard or medium-hard water area. Sites with multiple machines or significantly higher throughput would be better served by a larger or twin-tank softening system.

If you are working out whether this unit is the right match for your water conditions or machine setup, we are happy to talk it through.

EWC 20 Litre Manual Water Softener product image

EWC

EWC 20 Litre Manual Water Softener for Dishwashers

SKU: WS20

£194.00(£232.80 inc VAT)

The EWC 20 Litre Manual Water Softener is a compact inline unit designed to protect commercial dishwashers and glasswashers from limescale damage in hard or very hard water areas. It works by exchanging calcium and magnesium ions in the incoming mains supply for sodium ions, delivering softened water directly to the machine before it enters the wash cycle. No electrical connection is required — the unit operates entirely on water pressure, which keeps installation reasonably straightforward alongside most under-counter or pass-through dishwasher setups.

Hard water is one of the more consistent causes of early dishwasher deterioration in commercial kitchens. Scale builds gradually on heating elements, spray arms, and pump components, reducing wash performance and increasing energy consumption well before a machine reaches the end of its working life. An appropriately sized inline softener addresses that directly and helps sustain consistent results across a busy service period.

Protects heating elements and spray arms from progressive limescale accumulation
Helps maintain consistent wash and rinse performance over time
No electrical supply required — fits neatly alongside existing pipework
Stainless steel construction suited to a commercial kitchen environment
Flexible hose connection allows installation in tighter under-counter spaces

The resin bed that captures hardness minerals will exhaust over time and requires periodic regeneration using salt. How frequently that is needed depends on your local water hardness level and the daily volume your machine processes — sites with very hard water or high throughput will regenerate more often. It is also worth noting that this unit is intended specifically for dishwashers and glasswashers; it is not appropriate for ice machines, coffee equipment, or combi ovens, which require different filtration treatment.

This unit is well suited to smaller operations running a single dishwasher or glasswasher in a hard water area. Sites with higher throughput, more frequent wash cycles, or particularly severe water hardness may find a larger-capacity softener a more practical long-term choice.

If you are unsure whether this size is right for your water conditions or daily usage, we are happy to talk it through before you order.

EWC

EWC Prima Calcium Treatment Units for Coffee Machines

SKU: PRIMA-5, PRIMA-5-PK, PRIMA-10, PRIMA-10-PK, PRIMA-16, PRIMA-16-PK, PRIMA-23, PRIMA-23-PK, PRIMA-30, PRIMA-30-PK

From £154.00(£184.80 inc VAT)

The EWC Prima range of Calcium Treatment Units (CTUs) are water conditioning filters designed specifically for use with espresso machines and bean-to-cup coffee systems. Rather than simply filtering sediment, they work by treating the calcium hardness in the mains water supply — the primary cause of limescale build-up inside boilers, group heads, and heat exchangers. Left untreated, scale accumulation shortens equipment life, increases energy consumption, and affects extraction quality.

In a busy café or hospitality environment, consistent water quality is as important as the coffee itself. Hard water causes gradual but significant damage to espresso machine components, and descaling reactive maintenance is both disruptive and costly. A correctly sized CTU fitted inline before the machine provides continuous protection without interrupting service, and the treatment process also helps to stabilise the water profile in a way that supports better flavour and clarity in the cup.

From an operational and environmental standpoint, the Prima units offer a practical advantage over single-use plastic cartridge filters:

Regenerable resin means units can be returned, recharged, and reused rather than discarded
Reduced plastic waste compared to conventional disposable filter cartridges
Range spans from compact tabletop units through to multi-machine installations
Suitable for sites with varying water hardness levels across the UK
Long litre capacity between regenerations helps reduce ongoing maintenance intervals

Sizing is an important consideration. The correct unit depends on your local water hardness, daily coffee volume, and whether you are protecting a single machine or several. Fitting a unit that is too small for the throughput means more frequent regeneration cycles; fitting one that is oversized is rarely harmful but represents unnecessary outlay. The range covers tabletop single-group machines through to multi-machine setups, so there is generally a suitable option regardless of site size.

Installation is straightforward for a qualified plumber — the unit connects inline on the cold water feed to the machine and requires no electrical supply. Access for periodic regeneration or exchange should be factored into where the unit is positioned.

If you are unsure which size is appropriate for your water hardness and coffee volume, or whether a CTU is the right treatment approach for your particular machine, we are happy to talk it through before you order.
