Cool Clean CO2

  • Bonding surfaces are heterogeneous
    • Contaminating film types/thickness vary with area and from part to part
    • Combinational materials pose additional challenges
  • Unknown contaminant types and levels
    • Finger oils – complex acids/oils
    • Particles
    • Process residues
    • Mold release agents
  • Plasma only
    • Time sensitive – can’t work consistently (or possibly not at all) through uneven films and solid residues.
  • Integrated Spray only
    • No activation of bonding sites through oxidation or functionalization / surface activation mechanisms

“This technology provides significant environmental benefits and eliminates concerns such as wet chemistries, environmental permits, hazardous waste, bath degradation, bath maintenance, water and air pollution, and toxic chemicals.” -- COOL CLEAN

WHAT IS CO2?

~ CO2 (Carbon Dioxide) is captured as a by-product of natural and industrial processes (recycled CO2).
~ Cool Clean Technologies uses recycled CO2 which is environmentally friendly, as supported by the EPA.
~ Recycled CO2 has excellent characteristics such as low surface tension and viscosity to penetrate micro-surfaces for cleaning and cooling which are perfect for many industrial processes, to reduce energy usage and eliminate waste.
~ Recycled CO2 is non-toxic, non-corrosive and non-flammable (same as used in carbonated beverages).

WHY RECYCLED CO2?
~ Users of recycled CO2 are not generators of CO2 (EPA). ~ Recycled CO2 is non-cryogenic and can be temperature controlled. ~ CO2 cleaning technology is a cost effective and performance effective alternative for a variety of environmentally undesirable industrial agents. ~ Readily available by CO2 suppliers.

THE CLEANING POWER OF CO2
As a liquid or super critical fluid, CO2 has good solvent properties for removals of oils, greases and other common machining contaminants. Liquid CO2 (LCO2) has low surface tension and very low viscosity, which improves the likelihood that the solvent will wet the surface to be cleaned and penetrate into small crevices and blind holes. For certain contaminations, CO2 is useable with bio-based washing agents for increased cleaning power. In addition, LCO2 is an effective dry rinsing agent. The CO2 cleaning process can meet a variety of cleanliness requirements, ranging from visually clean and microscopically clean to total mass loss (TML), scanning electron Microscopy (SEM) and even acoustic microscopy (AM). CO2 possesses a unique cleaning solvent scheme which can be applied to many different types of challenging (and more general) device cleaning applications such as:

Applications:

  • Hard Disk Drives
  • Medical Devices
  • Microelectronics
  • Coatings
  • Fiber Optics
  • Solar Energy Devices
  • Many Others

Environmental Advantages

Clean Working & Production Environment: No discharge of pollutants into the air, water, and soil. No hazardous chemicals needed for superior cleaning results

Energy-Efficient: Use Cool Clean’s Cleaning Technology and consume less energy for cleaning, plus use less energy by eliminating energy intensive secondary processing such as drying and baking.

Recycled CO2: Cool Clean uses recycled CO2, the same as used in carbonated beverages. No new CO2 is generated

Environmentally Friendly: Reduction in waste generation, no hazardous materials needed, no toxic chemicals. The use of recycled CO2 is supported by the Department of Energy and the National Science Foundation.
