Puretec CO-RO4 High Flow Reverse Osmosis Undersink Water Filter System with Bypass

The Puretec CO-RO4 High Flow Reverse Osmosis Undersink Water Filter System with Bypass is a premium commercial-grade water filtration system designed for food service, espresso and hospitality applications requiring ultra-pure water with adjustable mineral retention. Combining advanced reverse osmosis technology with a unique bypass and remineralisation system, the CO-RO4 allows cafés and commercial operators to fine-tune water quality for optimal coffee extraction, beverage flavour and equipment protection.

Designed specifically for high-performance espresso and food service environments, the CO-RO4 removes up to 96% of dissolved impurities including fluoride, salts, chlorine, chemicals, heavy metals, bacteria, viruses and sediment through its advanced 4-stage filtration process. Unlike traditional reverse osmosis systems that completely strip minerals from the water, the integrated bypass and Mg+ remineralising technology help restore balanced mineral content to improve flavour while reducing the risk of corrosion and flat-tasting water.

Its adjustable bypass valve allows operators to customise TDS levels and flow rates depending on water quality requirements and equipment specifications. The system also features an integrated membrane flushing design to help minimise bacterial build-up and extend membrane life, making it ideal for demanding hospitality and commercial applications.
