Case Study: Real Business, Real Results

The Harbour View Bistro in Portsmouth was struggling with the effects of the region's notoriously hard water. Despite using a premium rinse aid, their glassware was persistently cloudy, and  their Classeq P500 pass-through washer needed frequent descaling, causing service interruptions.

"We fitted the Classeq softener and  the difference was immediate. Our glasses are now gleaming, and  we're not constantly battling limescale. It’s saved our pot wash team so much time and  effort, and  the engineer hasn’t been called out for a descaling job since."

Michael Davies – General Manager

The bistro has since reported a 90% reduction in dishwasher maintenance calls and  consistently perfect wash results.

Installation and  Maintenance Guide

Setting It Up

  • Position the unit on a flat, stable surface next to your warewasher.
  • Connect the inlet hose to a cold water mains supply.
  • Connect the outlet hose to the warewasher's water inlet.
  • Fill the unit with granulated dishwasher salt before first use as per the manual.

Keeping It Going

  • Regularly check the salt level and  top it up as needed to ensure performance.
  • The frequency of salt refilling depends entirely on your water hardness and  usage.
  • Periodically inspect the connection hoses for any leaks or kinks.
  • Follow the manual instructions for the simple regeneration process when required.

Buying Guide: Choosing the Right Commercial Water Softener

Feeling a bit lost in the world of water treatment? Here are a few key pointers to help you Select the right commercial water softener for your dishwasher.

Check Your Water Hardness

Before you buy, find out the water hardness in your area. You can usually find this on your local water supplier's website. This softener is essential for anywhere above 7° Clark (100 ppm).

Match Capacity to Usage

Consider how many wash cycles you run a day. A high-volume site needs a softener, like this 20-litre model, that can keep up without constant regeneration or refilling.

Measure Your Space

These units sit externally, so make sure you have adequate space next to or behind your warewasher. Check the dimensions (900x180mm for this one) against your available room.

Manual vs. Automatic

This model is a manual, non-electric unit, which means it's simple and  reliable but requires you to top up the salt. Automatic softeners exist but are often more complex and  expensive.

Consider Compatibility

While many softeners are universal, choosing one from the same brand as your dishwasher (like this Classeq unit for a Classeq machine) often guarantees a perfect and  seamless fit.

How Base Exchange Stops Limescale in Its Tracks

Ever wondered what 'base exchange' actually means? It's a clever but simple process that acts like a magnet for the minerals that cause limescale. Think of hard water as being full of tiny, sticky troublemakers (calcium and  magnesium ions). Inside this softener is a bed of special resin beads. As water flows past, these beads grab onto the 'hard' minerals and  swap them for 'soft' sodium ions from the dishwasher salt you add. It’s a straightforward trade that neutralises the limescale threat before it has a chance to clog up pipes, coat heating elements, or leave that dreaded cloudy film on your glasses. This simple science is what keeps your machine healthy and  your tableware sparkling.

Who Should Buy This?

  • Busy Restaurants: To guarantee spotless glassware and  cutlery, upholding high standards even during the dinner rush.
  • Local Pubs & Bars: Protects the glasswasher from hard water damage, ensuring pint glasses are always crystal clear.
  • Independent Cafés: Keeps coffee cups and  teapots free from stains and  limescale film, enhancing the customer experience.
  • Hotel Kitchens: An essential for maintaining high-volume warewashers and  preventing costly operational downtime.
