From Firbimatic experience in the industrial activity and also thanks to the gratifying successes that has followed the specialization in the cleaning of precision engineering components as well as aerospace parts, our hermetically solvent degreasing machine are capable to perform a cleaning and drying treatment cycle under high vacuum level.
Our solvent cleaning machine are prepared for use different solvents:
Systems with Hydrocarbon Solvents (class AIII) or Modified Alcohols
Systems with Chlorinated Solvents
Both of them are designed to ensure the best quality of cleaning, thanks to the hermetic vacuum operation, which ensures the best cleaning results on complex surfaces, inside of the cavity and blind holes.
The prior degassing of the solvent which continues during the full immersion phase, ensures absolute absence of air bubbles and so the penetration and homogeneity of the dipping bath.
At the end of the cycle, thanks to the drying stage with vacuum values less than 2-3 mBar, parts come out completely deodorized and without any solvent residue that can contaminate the work environment.
The solid particles of dirt, such as dust, metal chips and inorganic salts, are effectively removed by the mechanical action of the cleaning cycle combined with the selected movement of the basket.
Any layers of burned oil and additional contaminated solids deposited on the component (eg: Oxides and lapping and polishing pastes) require instead the action of ultrasonics that can be installed on request in the majority of our closed-circuit systems.
The distillation process, vital function of solvent machines, consists of two distinct phases which allow an almost total separation between solvent and oils and it is distinguished by a negligible presence of solvent in the distillation residues.
In particular, the continuous distillation of the solvent (main phase of distillation) is alternated to the phase of Boil down of the still residues. This boil-down phase is made typically at the end of the day in the main distiller (or, if the option is present, through the secondary distiller).
Boil down of oil sludge has the purpose of reducing the solvent content to values <1-2% of the sludge, which are then automatically ejected in a timed phase (under temperature control).
The operator NEVER comes in contact with the solvent since all the management operations of sludge of distillation and the cleaning of filters take place automatically.
In our solvent cleaning machines, we can estimate an average consumption of very few liters of solvent per year if the following conditions are met:
- Correct choice of the treatment program; that is by using only the pre-loaded programs in the machine by our technicians during commissioning and start-up of production.
- Proper management of the distillation of the solvent; that is by performing the steps of distillation according to the amount of contaminant brought to machine and not manually forcing the procedure of distillation.
- Regular maintenance and cleaning; operating according to the appropriate time period indicated in the user manual.
The technical dept. of Firbimatic, once properly appraised each specific cleaning problems of any affected customer, will then present a customized proposal for the best suited cleaning system to achieve a guaranteed cleanliness result.
