Zip Chillmaster – Free Standing Chilled Water Zip Chillmaster is a free standing chilled filtered water appliance for hospitals, clinics, reception areas and schools. It comes with a carafe, bubbler, stainless steel bowl and case and a standard five micron triple action filter or an optional sub micron triple action filter. Five Micron filters remove dirt, rust and particulates that contaminate drinking water. They also remove organic contaminants and eliminate offensive odours by reducing chlorine and other chemicals. Sub Micron filters perform all of the above but in addition filter out asbestos fibres and micro-organisms such as cryptosporidium and giardia to International Standards 42 and 53. We recommend filter replacement at intervals of 6 to 12 months depending on levels of usage and water quality.
