Filters

Water filtration is the simplest and most effective way to extend the service life of an ice generator and improve the quality of the ice produced in bars and restaurants. The tap water has a moderately high limescale content, which, without filtration, quickly accumulates in the ice generator’s pipes, cooling element, and dispensing mechanism, leading to the need for more frequent maintenance and premature wear.

Types of filters for ice generators

Professional filters for ice generators are available in several types, depending on the water issue and filtration needs. Mechanical filters (sediment filters) — remove impurities and iron, protecting the generator from mechanical damage. Activated carbon filters — reduce chlorides, unpleasant tastes, and odours, improving the organoleptic properties of the ice, such as taste and aroma. Limescale inhibitors (scale inhibitors) — reduce the formation of limescale deposits in pipes and on cooling surfaces without softening the water; more suitable for smaller systems. Ion-exchange softening filters — exchange calcium and magnesium for sodium, effectively reducing water hardness; ideal for regions with high water hardness. Combined filtration systems — integrate multiple filtration technologies in a single cartridge or system for universal water quality improvement. Also explore Ice Storage Bin.

Impact of filtration on ice quality

Water filtration directly affects the visual and organoleptic quality of the ice produced. Ice transparency — cleaner water with lower mineral saturation produces more transparent, visually appealing ice; cloudy ice indicates high mineral content or dissolved gases. Taste and aroma — reducing chlorides and organic substances improves the neutral taste of the ice, which is especially important for delicacy cocktails and tasting beverages. Ice shape — limescale buildup on the cooling surface affects the ice shape and production speed; a filter ensures consistent production of cubes, fingers, or other shapes.

Filter replacement frequency

Regular filter replacement is critical for maintaining effective filtration. Replacement interval — typically every 6 months or after 15,000–20,000 litres of filtered water; higher water hardness requires more frequent replacement. Visual warning signs — reduced water flow through the filter, an unpleasant taste in the ice, or decreased generator productivity all indicate a clogged filter. Replacement process — in most systems, filter cartridge replacement is simple, thanks to a quick-change bayonet connection. Filter testing — a water hardness test before installing the equipment helps determine the most suitable filtration system.

HoReCa usage scenarios

Bar with a premium cocktail programme — high-quality, transparent large-cube ice for cocktails requires clean, filtered water; an activated carbon filter ensures the ice has a neutral taste that does not affect the drink’s aroma. Restaurant with high ice consumption for beverage service — a limescale inhibitor reduces the need for generator repairs and extends its lifespan, lowering overall operating costs. Café with a combined coffee-cocktail bar — a water-softening filter improves the service life of both the ice generator and the espresso machine, reducing maintenance costs.

Frequently asked questions

How often should the filter in an ice generator be replaced? Usually every 6 months or after 15,000–20,000 litres; more frequently in hard water. Contact BHS. Also explore Ice Generators.

Does a filter improve ice transparency? Yes — filtered water with a lower mineral content produces more transparent ice.
