Cold Clean is a term coined by Smith Engineering to describe the philosophy adhered to in the manufacture of water treatment systems meeting a variety of purity standards. Cold Clean is an alternative to heated technologies for the production of low/no microbial process water. Typical designed specifications include:
Resistivity/Conductivity
pH
Microbial/Endotoxin Levels
Total Organic Carbon
Methods:
RO or RO/DI feeds Microfiltration/Ultrafiltration
Recirculating Design within the treatment equipment and storage
Zero Dead Leg Design and Components
Continuous Distribution System Velocity
Ultraviolet Sterilization
Routine Chemical Sanitization
Materials:
Quality materials of construction including 316l stainless steel housings and vessels
Sanitary, non-metallic piping materials beyond the last point of treatment.
USP Class VI Plastics and Elastomers
Motivation:
Significantly lower capital cost than traditional stainless steel systems
No utility requirement for steam/heated water
Lower operating cost; no requirement to power expensive
Energy consuming heaters or stills
Easily installed, modified, and expanded
Design thru Qualification capabilities from a single vendor
