The Cube Max-CP1L single-stage filtration system improves efficiency while reducing service calls and downtime associated with scale buildup and corrosion damage in commercial ice machines. Unit consists of two 3/8-inch NPT Lead Free brass ball valves, flush kit for easy installation and easy maintenance, and a high-strength polypropylene filter housing mounted on a powder-coated steel bracket. Water pressure gauges on the inlet and outlet port show the pressure drop across the unit to help determine when the filter cartridge needs to be replaced for optimal unit performance. System features one 20-inch carbon and polyphosphate filter for sediment, chlorine and scale reduction.
