Cold-Clean™ Technology

Cold-Clean™ refers to Smith Engineering’s line of DI-Ultrafiltration Purified Water Systems that are a perfect fit for manufacturing applications that require low/no microbial and/or endotoxin content. Our Cold-Clean™ line provides purified water meeting the quality requirements found in USP Purified and WFI, all without the use of heat. System sizes begin at a 5 gpm flow rate  and can be built in multiples of that size. Typically incorporation of a serpentine distribution loop is required; materials are chosen based on the final water quality specification requirement.

Cold-Clean™ is a term coined by Smith Engineering to describe the philosophy adhered to in the manufacture of water treatment and distribution system meeting a variety of purity standards. Cold-Clean™ is an alternative to heated technologies for the production of low/no microbial process water. Typical design specification include the following:

• Resistivity / Conductivity
• pH
• Microbial / Endotoxin Levels
• Total Organic Carbon
