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
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
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.
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
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
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.
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.
