Catering Insight has taken a look at the latest commercial kitchen water filtration technology on the market, and found the following:
Brita Purity C Steam
The Brita Purity C Steam is designed to maximise steam cooking and baking, while protecting vital catering equipment by providing optimally filtered water. Brita’s Systematic Filter Technology decarbonises water in four steps to ensure both quality and consistency of food preparation.
The steps comprise pre-filtration to retain coarse particles; carbonate hardness reduction to prevent limescale formation; water runing through an activated carbon filter to reduce taste- and aroma-impairing substances; while a fleece retains fine particles.
The IntelliBypass technology used allows for a constant by-pass water rate, irrespective of the volumetric flow. This should ensure a consistently high water quality, particularly in case of low water throughput rates.
The filter cartridges, specially developed for small to medium-sized combi steamers and ovens, reduce carbonate hardness in drinking water and, as a result, should prevent limescale formation in equipment. In addition, the filter medium retains metal ions such as lead or copper and reduces substances, for example chlorine, that can negatively affect the taste and aroma of baked products, fish, meat and vegetables.
The iX Water filter is an eco-friendly cartridge water filter, made in Britain. Using insert refill technology, users can decide whether to quick change by easily fitting a replacement cartridge – or saving costs and reducing environmental impact by changing the insert by using the special tool provided.
Insert refill technology is designed to provide a sustainable and cost effective alternative to cartridge filters already in the marketplace. It also allows supplier European WaterCare to recycle all the plastics returned to the company. In addition, it regenerates the resin media inside the refills and re-uses it in the replacements. This allows the firm to keep end user costs to a minimum whilst providing an ethical service and minimising the amount of plastic used to manufacture.
The filter is designed for ease of maintenance. The iX Water head has quick shut off valves and a digital flow meter so the volume of water that the filter has treated can be seen. This is designed to enable quality treated water at all times, as filters can be changed with accuracy rather than on an estimated timed period.
The iX Water filter can be used on coffee machines, water coolers, ice machines, vending machines and catering applications.
3M High Flow Series
3M High Flow Series water filters are specialised for ice machines and help to prevent scale build-up and sediment particles that put the units at risk of breakdowns, increased maintenance and inefficient operation, and could cause profits and customer experiences to suffer.
A single cartridge has high flow rates and capacities which were previously available only with three or four cartridge systems. They are designed to last for up to 12 months and feature Sanitary Quick Change (SQC) encapsulated cartridge design for fast and easy change-outs.
The series provides direct or easily adaptable connections to existing plumbing lines, and is certified to NSF Standard 53 for cyst reduction. With a claimed reduction of 99.99% of waterborne bacteria, the filters are designed to deliver ‘recipe quality water’ for all commercial foodservice applications.
The 3M product employs Integrated Membrane Pre-Activated Carbon Technology (IMPACT) featuring polypropylene housing, and media with a pleated membrane design helps provide cyst and bacteria protection and sediment holding capabilities with minimal pressure drop. Carbon block technology is claimed to have more than four times the chlorine taste- and odour-reduction capacity of a competitor’s pre-coat filter, plus the pleated membrane media in the HF90 model reportedly has six times the surface area of a competitor’s filter. Furthermore, cartridges feature a 5 micron prefilter wrap.
