DOLFİN-KBN1 series parts washing machines are used before and after overhaul in repair and maintenance services, especially for washing large and heavy parts. Apart from revision workshops, it is also used for cleaning the surfaces before assembly or packaging in enterprises and factories that produce parts in series. They are special devices designed for large sized and heavy parts such as engines and parts of construction machines, power plant turbines. While the parts placed in the device are rotated on its own axis by means of the washing basket, pressurised detergent hot water is sprayed. Thanks to the pressure, temperature and chemical effect, all oil and dirt on the parts are cleaned.

Dolfin RTS series Rotational basket washing machines, washing small and complex surfaces It is a compact parts washing machine used for precise and high-level cleaning of problematic part types. The parts that are placed in the washing basket one by one by positioning and / or in bulk are first sprayed with alkaline chemical washing liquid at high pressure to every point of the parts in the device. Then the washing cell is filled with this liquid and the parts are contacted with ultrasonic sound waves. Therefore, thin section detail points, internal holes and channels are cleaned at a high level. In the process, the basket is rotated on the vertical axis and both spraying and ultrasonic effect is penetrated to every point of the part. At the end of this process, the washing liquid is directed to its own tank, while the same process is applied for rinsing and/or liquids in the other tank.

Dolfin KNV series conveyor belt washing machines are parts washing machines used for washing parts produced in series in large quantities. The parts placed at the entry point are moved towards the exit point of the device by means of the conveyor. The parts guided on the conveyor line are washed with high pressure, pre-washing, washing, rinsing, spraying with passivation liquids. At the end of the cleaning process, these parts are dried with pressurised hot air and discharged at the exit point. If desired, it can be integrated into production processes and robotic loading and unloading options are also available. While the entire device is fully automatic, all washing details are parametric. Cleaning is provided at any desired level by means of spray nozzles specially designed according to the part geometry.

"DOLFİN- VDL series Drum (Spiral) parts washing machines are used especially for cleaning small parts with high production quantities and produced in bulk. The materials poured from the inlet part of the spiralised drum in the device are directed towards the outlet part of the drum by the spirals inside the drum. While the drum moves on its own axis according to the set rotation speed, the parts are subjected to washing (degreasing), rinsing, passivation and drying processes respectively (depending on the model). Since these processes are sequential and continuous, all processes are completed quickly and effectively in a single device. Full penetration is achieved by pressurised spraying and immersion effects in each section. It is a very functional model used especially for washing bolts, nuts, washers, or small parts of this type, and fittings, nipples, couplings and fittings processed in high quantities on cnc and automat machines.
