Solvent washers

Washing of parts with industrial degreasing agents

Coniex supplies solvent washers for the washing and degreasing of metal parts. This type of parts washer is suitable for all types of production volumes and for parts of large size and/or complicated geometrical shapes, since the rotation of the basket with the parts on a rotating platform guarantees the washing of the parts on all their sides, avoiding dead angles.

Industrial degreasing by means of closed circuit solvent washers is ideal when a quality surface treatment is required at a reasonable cost, as well as a guarantee of consistent results.

The equipment is available in standard and special operation versions with chlorinated solvents, aliphatic hydrocarbons, hydrofluorocarbons, brominated solvents and HFE .

Solvent washers are particularly effective for degreasing complex parts with difficult geometries, such as blind holes, through holes, welding, etc. This equipment achieves good degreasing through repeated spraying, immersion and vapor phase stages.

Solid dirt particles, such as powders, metal powders and inorganic salts are effectively removed by a process of action combined with specific movements of the cleaning baskets. On the other hand, burnt oil components or other contaminating solids on the part (oxides and polishing pastes) require ultrasonic action, which can be installed upon request.

The main advantages of this solvent degreasing system are the following:

  • Negligible emissions for the environment (much lower than the limit indicated in the VOC 13/99 regulation).
  • Savings of more than 90 % of the solvent system compared to open channels
  • Exceptional washing and drying performance (possible application in the medical, aerospace, electronics and precision industries)
  • Total elimination of all residues (oils, metallic powders, wax, foundry sand, etc.).
  • Dry with clean solvent and distillate in each cycle (constant quality wash).
  • Clean and tight drying

Range of solvent washers

Solvent equipment is divided into models using brominated chlorinated solvents (MD-V range, SF-V, EV), models using high flash point aliphatic hydrocarbons – Class A3 (Gamma MDK, SFK), and models using special solvents (hydrofluorocarbons, etc.).

The choice of solvent and of the washing and degreasing equipment depends on the degree of affinity of the solvent with the contaminants to be removed, and on the nature of the material of which the part is made.

Our solvent washers are very versatile and can be customized to the needs of each application:

  • The SF-V and EV range, whether solvent or chlorinated hydrocarbon (K Series), are equipped with a single large door basket (on request up to 1,500×3,000×1,500 mm) and are suitable for large parts.
  • The MD and MDK series multi-basket models are adapted to high productivity demands. Depending on the model, you can have rotation options, or TILT ROTATE THE BASKET.

Thanks to their flexibility, solvent washers can incorporate different processes:

  • Degreasing by high-pressure spraying, immersion baths with hot and cold water, and treatment (partial or total) with ultrasound.
  • Washing and rinsing by spraying, immersion, and solvent vapor phase.
  • Ultra-cleaned filtration phase to 5 microns.
  • Vacuum drying or air recirculation.
  • Subsequent passivation phase with special additives for a long conservation of the parts.

Accessories for our solvent washers:

  • 1 hot solvent storage tank
  • 1 solvent cold storage tank
  • 1 module of continuous distillation to solvent regeneration
  • Gravitational double water tab – solvent
  • Closed-loop condensing of the complete system with refrigeration equipment (chiller) for the heat pump
