The System:


Spray cleaning Equipment  -  Environmentally Friendly Solvents
Fume Containment Glove Box – Fume Extraction System


System 4450CA – Mini Clean Room

The Cobehn System 4450CA "Mini Clean Room" is a process controlled, fully integrated cleaning and fume containment system designed for hi-rel applications which require strict control over the duration of the staging, cleaning, and drying cycles which make the Cobehn system so effective in cleaning in cleaning critical components. 

A digital process controller provides the ability to program the number of seconds for each of the cycles to ensure the most effective and efficient cleaning and drying for each component, regardless of size or complexity of the device being cleaned.  In addition, the controller allows the settings for both operating pressure and temperature to allow flexibility in using different solvents depending on the contaminant to be removed at each step of the manufacturing process.  Once all parameters have been set, they can not be changed without access to the 4 digit security code.

The custom engineered stainless steel glove box serves two purposes. Not only does it provide a "mini clean room" environment to ensure components are not exposed to new contaminants after cleaning but it protects the technician from exposure to any vapors that might be present during the cleaning process. When connected to the Cobehn Fume Extractor unit the system becomes a self-contained, air tight system protecting everyone within the work environment from chemical exposure.

Flexibility and adaptability is a trademark of all Cobehn equipment and the System 4450CA is no exception. To ensure the ability to clean even larger devices the system is equipped standard with a dual nozzle and shut off valve to disable one nozzle when cleaning standard size components.   Since larger size components generally require more flexibility in the cleaning process a simple switch converts the system to manual operation allowing the technician to control the length of the spray cycle using a foot pedal.

For larger volume applications the unique Cobehn design allows the incorporation of custom designed parts holding devices which, when combined with the air driven, oscillating parts transporter, permits the automated cleaning of multiple parts in a consistent and uniform manner with only minimal operator intervention to load and unload the parts racks.

FUME EXTRACTION EQUIPMENT  

The unique nature of our industry occasionally dictates that a solvent be used that is toxic, emits VOC's, or has odors which are unpleasant in a work environment. The Cobehn Fume Filtration System, used in conjunction with the custom crafted glove box, provides the ultimate in work place safety. Available in a variety of sizes, these explosion rated units use activated carbon and pleated filters to remove flammable or noxious fumes and trap them completely. All emissions are contained, leaving only the filters to be changed when needed.
With the complete Fume Filtration System in place, the Cobehn process can safely be used in facilities without ventilation equipment as well as in parts of the country where increased environmental sensitivity is a factor.

 

COBEHN MODEL 1400 

The Cobehn Model 1400 provides a low cost and environmentally friendly solution for the critical cleaning of electronic, mechanical, and optic devices from the very smallest to 12" in size that require cleaning to ensure long term reliability, appearance, or secondary process requirements.
Using a patented venturi design atomizing sprayer it gently removes both organic and inorganic contaminants including fluxes, oils, fingerprints, dust, and particulates.   It can be used with virtually any solvent or alcohol to thoroughly clean printed circuit and smt boards, micro-electronic components, optic devices, ball bearings, other precision mechanical devices, and any component requiring either basic or more critical cleaning.
Using only a minute amount of solvent its gentle impingement process quickly cleans and dries even the most intricate and complex components without the need to deal with any hazardous waste disposal issues.  Devices are cleaned and dried in a one short 10 to 20 second process that can be performed without skilled labor.
Whether used in conjunction with, or as alternative to, ultrasonics, vapor degreasing, plasma, or simple hand cleaning, its cost effective and simple process have been used in a variety of manufacturing and lab applications installations for over 50 years.

Solvents – Ultra Pure Solvents Filtered to 2 Microns
Cobehn solvents are used for many different cleaning applications including the removal of ionic (polar), non-ionic (nonpolar) and particulate soils.  Each product has different characteristics to address specific critical cleaning needs and Cobehn can offer suggestions and product testing for your evaluation.
Cobehn Systems, clean room processed solvents are filtered to 2 micons to eliminate particulate matter.  This exclusive processing procedure eliminates the contamination inherent in bulk packaged electronic grade solvents supplied in pails and drums.
To assure purity all Cobehn Solvents are packaged only in quart and gallon containers which have been washed, solvent rinsed and dried.  After the filling process they are cello-sealed to preserve integrity and controlled by manufacturing lot number.

Vertrel Series
Vertrel SMT – a non-flammable hydroflourocarbon, is intended for use in removal of flux, grease, oils, waxes, and ionic residues.  SMT’s low surface tension makes it an excellent particle eradicator.  SNAP listed.  Acceptable TLV’s.
Vertrel MCA (+) – a non-flammable hydroflourocarbon with cycopentane – is intended for use in precision cleaning applications such as precision cleaning of metals, removal of heavy oil, grease, wax, vacuum oil and difficult soil situations.  Very effective when removing silicon based oils and mineral oils.  SNAP listed.  Acceptable TLV’s.

Cobehn Spray Clean Solvent
Cobehn non-flammable Spray Clean Trichloromethane is intended for use in difficult flux removal situations as well as in the removal of grease, oils and particulates where no other material will handle the job.  While not a CFC or ODS spray clean solvent is extremely cost effective, but is a VOC with a low TLV requiring that it be used with a Cobehn Fume containment Chamber to assure that vapors cannot escape into the work area.

AK225
Cobehn’s non-flammable AK225 is an environmentally safe HCFC designed to replace CFC’s and PFC’s which have high ozone depletion potentials.  Like other Cobehn ultra pure solvents AK225 is filtered to 0.2 microns and is an excellent choice for the final cleaning of precision mechanical and electronic devices.  It is safe on most metals and plastics and is not a VOC.
