VACUUM TO VACUUM SYSTEMS

Work Area Safety
Vacuum-To-Vacuum Degreasing Systems are designed to contain less than 25 ppm in the degreaser prior to opening the chamber door. EPA testing consistently measured less than 15 ppm in the Degreasing chamber.

Low Emissions to the Environment
The Vacuum-To-Vacuum Degreasing System is a completely closed looped system. Emissions can escape only when opening the chamber. Because of this, Vacuum-To-Vacuum Degreasing Systems have practically zero emissions.

Low Solvent Usage
Vacuum-To-Vacuum Degreasing System typically recovers 99.9% of vapor and liquid solvent from the chamber during the drying process.

Flexible Operating Temperatures
Because Vacuum-To-Vacuum Degreasing System units operate under full vacuum, the solvent in the system is boiling at any temperature. The concentration of the vapor in the chamber, however, is dramatically affected by the temperature. The Vacuum-To-Vacuum Degreasing System utilizes solvents at approximately 60-90% of the boiling point temperature, adding flexibility especially when processing temperature-sensitive material.

Better Cleaning Efficiency
Temperature is an important parameter when considering cleaning efficiency. Higher temperatures lower the viscosity of both the contaminant and solvent. Higher temperatures also promote faster solvent condensing and greater flushing volumes of solvent. The Vacuum-To-Vacuum Degreasing System can be optimized to operate at the highest, safest temperature for your particular cleaning equipment.

Excellent Drying
The Vacuum-To-Vacuum Degreasing System utilizes vacuum drying. Vacuum levels are so deep that solvent actually boils off the parts since heat is held in the parts. This heat source along with deep vacuum levels ensures all solvent removal from the part and chamber.

Reduced Waste
The Vacuum-To-Vacuum Degreasing System utilizes vacuum during distilling and solvent recovery. The solvent remaining after distilling is generally less than 0.1%. This minimizes the amount of solvent in the waste stream, which can lower costs considerably.
Elimination of Water Mixing With Solvent The Vacuum-To-Vacuum Degreasing System is designed to eliminate any air/solvent vapor mixing. By preventing this interaction and the resulting corrosion concerns the Vacuum-To-Vacuum Degreasing System can be fabricated with common carbon steel materials, reducing equipment cost.

Solvent Compatibility
Since oxygen is removed prior to solvent vapor entering the vessel, flammable solvents can be used. Since there is no requirement on the solvent producing heavy vapors, solvents with low molecular weights can be used. Vacuum Processing Systems has designed units that use an alcohol.

Low Energy Costs
The Vacuum-To-Vacuum Degreasing System uses heat and cooling only when operating. There is no wasted energy in boiling off and condensing vapors when the machine is idle.

Reduced Reporting and Permit Costs
Vacuum Processing Systems designs systems so that emissions fall under the minimum permit requirements. Generally, this requires only the reporting of annual solvent usage. Since solvent usage is reduced 95% or more, as opposed to open top vapor degreasing, little record keeping and paperwork is required when utilizing Vacuum-To-Vacuum Degreasing System compared to open top vapor degreasing.

Reduced Maintenance Requirements
Our Vacuum-To-Vacuum Degreasing Systems are self-cleaning. Since contaminants and water are continuously removed from the system, no shutdown and clean-out of the system is required.

Increased Capacity
Vacuum-To-Vacuum Degreasing System units have higher capacity than equivalently-sized open top degreasers because the airless design eliminates the need to limit the rate at which heat is added to the process chamber.

Solvent VCN Systems
Solvent VCN systems combine the capabilities of an Airless degreaser with the power of the VCN process.
