Principles of Cold Clean Technology

ccimg1

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

ccimg2

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

ccimg3

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:

    ccimg4
  • 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
  • Green design
