We are specialists in delivering ATEX-zone 2 cleaning systems used for explosion hazardous liquids and our standard system is available with both washing, rinsing and drying in an automatic and manual version. This system is cleaning the parts with ultrasonic cleaning and can be used for solvents and alcohols with a flash point of down to 12°C.

The system comes standard with ultrasonic cleaning, rinsing and drying in a unique design, where safety and functionality are paramount, which is clearly reflected in the amount of standard equipment.

The explosion protection is such that we add nitrogen to the ultrasonic cassette where the transducers are placed inside the ATEX zone, thereby removing the risk of ignition. The uniqueness of our system is that we do not have a continuous addition of nitrogen during operation, which would create a large consumption and need for a large nitrogen container, often creating some other safety issues.

Instead, we have a constant pressure monitoring of the ultrasonic cassette which is connected to a small container of nitrogen which simply maintains the nitrogen pressure and gives an alarm if a pressure drop occurs.

In addition, the cleaning system is supplied with two fans which in normal operation, operate at half capacity and in case of a breakdown on one fan, the equipment automatically switches to full operation on the other so that the risk of creating an explosive atmosphere is minimized.

In addition, both fans are equipped with a UPS which, in the event of a power failure ensures that the extraction continues for a limited period of time so that the equipment can be emptied of liquid, thereby avoiding an explosive atmosphere.

The ultrasonic cleaning system is supplied with antistatic bracelet for the operator, which ensures grounding during operation of the equipment so that the risk of ignition is eliminated during operation of the advanced cleaning system.

This cleaning system is widely used in the 3D printing industry for cleaning SLA-printed parts in epoxy and acrylic resin, but is offered for all tasks where it is necessary to work with explosive liquids. It is supplied both as a standard and special solution depending on the customer’s needs.
