Ice is often treated as an afterthought, but the water entering an ice machine can affect both the quality of the ice and the performance of the equipment.

For restaurants, cafés, hotels and other foodservice businesses that rely on ice throughout the day, the right water filtration system can help reduce water-related issues such as scale, sediment and unwanted tastes or odours.

How Water Affects an Ice Machine

An ice machine repeatedly freezes incoming water. Depending on the water conditions, dissolved minerals and particles can gradually accumulate inside the equipment.

Scale build-up can affect components such as distribution lines, evaporator plates and pumps. Appropriate filtration and scale control can help reduce clogging and water-related maintenance problems in commercial ice machines.

Filtration can also help improve the taste and appearance of the water used to produce ice.

This is particularly relevant for ice served directly in beverages, where unwanted tastes or odours may affect the overall drinking experience.

What Does an Ice Machine Water Filter Do?

The exact performance depends on the filtration system used, but commercial ice-machine filters can be designed to address several areas.

Reduce Sediment and Particles

Fine dirt and particles entering the machine can accumulate within internal components.

Mechanical filtration helps capture these particles before they enter the ice machine.

Reduce Chlorine Taste and Odour

Chlorine is commonly used in drinking-water treatment.

NSF/ANSI Standard 42 covers filtration claims relating to aesthetic effects such as chlorine, taste and odour.

A filter certified for the relevant claims can help reduce these characteristics in the water before it is frozen.

Help Manage Scale

Scale forms when minerals in water accumulate on equipment surfaces.

In an ice machine, excessive scale can contribute to reduced performance and additional maintenance.

Some commercial filtration systems therefore include scale-inhibition technology specifically designed to help protect equipment.

Everpure Filtration for Ice Machines

The Everpure i20002 is designed specifically for ice-machine applications.

The system combines filtration with scale inhibition to help reduce chlorine taste and odour, fine particles and water-related scale problems.

The i2000 series is designed to help reduce scale formation and particulates while providing filtered water for commercial ice applications. Systems in the range are also certified under NSF/ANSI Standards 42 and 53.

How Often Should an Ice Machine Filter Be Replaced?

Filter replacement depends on the cartridge capacity, water conditions and actual water usage.

For the Everpure i20002, Pentair recommends changing the cartridge as part of a regular six-month preventive maintenance programme, or earlier if its rated capacity is reached or water flow becomes inadequate.

Following the manufacturer's recommended replacement schedule helps ensure that the filtration system continues performing as intended.

GFS Innovation supplies Pentair Everpure filtration systems for ice machines, cafés, restaurants, hotels and other foodservice applications.

Selecting the right filtration system can help maintain ice quality while protecting the equipment that produces it.
