Hydrokinetic washing machines

Washing of parts by immersion and spraying

Coniex designs and supplies hydrokinetic washers for the washing of parts and components of special complexity that require a high quality final wash. We have different models for different productivities. Our hydrokinetic washers operate exclusively with water-based detergents.

Hydrokinetic washers are flexible machines and equipment, ideal for cleaning complex parts with blind holes and cavities. They are one of the few equipment that allow to wash parts placed inside dedicated stainless steel structures with high precision.

These are washing machines that include a rotating drum for hot washing with spraying and immersion. This equipment guarantees a simple loading and unloading process, in accordance with ergonomic and safety principles.

The machine is equipped with PLC system and can be manufactured with several washing and degreasing phases or cycles. The washer is capable of performing the immersion and spraying phases separately or simultaneously.

The equipment ensures a high degree of cleanliness, even without the need for specific washing tools, thanks to the rotation of the parts immersed in an aqueous solution (water + detergent), which is agitated with pressurized water jets.

The system continuously filters the washing and rinsing baths, carrying out the separation of oily residues through integrated oil separators.

The rotation of the parts on the horizontal axis facilitates drainage, avoiding the stagnation of fluid in it. Depending on the type of parts to be treated, it is possible to select the type of rotation: alternating, continuous, oscillating, or even static for very delicate components.

The drying phase is carried out in a closed circuit of forced convection and/or vacuum, depending on the type of parts to be treated and the materials of which they are made.

The compact dimensions of the equipment make it particularly suitable for integration into work islands, or for placement near a machining center. For high production volumes, it can be supplied with a roller conveyor for manual handling, or with an automatic motorized loader of the baskets.

They are constructed in high quality AISI 304 stainless steel with the tank area separated from the treatment area.

Hydrokinetic washers contribute to operating cost savings by incorporating innovative heat recovery systems.

The start-up of the washing machine is carried out from a PLC with touch screen. The entire process is fully automated.

The pieces are placed on a rectangular stainless steel grid basket that the operator manually inserts into the drum, where cleaning and degreasing are carried out. Once the front door is hermetically closed, washing starts automatically.

During washing, the basket rotates slowly so that all parts of the piece can be accessed. Speed and rotation mode, continuous or tilting, are set on the touch screen panel.

In each of the available programs, all the working phases can be freely configured: spray washing, immersion washing, compressed air blowing, heat drying and immersion ultrasound.

Hydrokinetic washers offer various options for washing complex parts, such as intermediate or final rinses, or drying by means of vacuum pumps or ultrasonic emitters that increase efficiency and cleanliness.

Drying is carried out with hot air and, as mentioned above, can be enhanced with a vacuum pump system.
