Applications

Degreasing systems of the VARIO series are the right choice in many cases of need in turning technology. An abundance of possible options guarantees the optimal design of the plants for very special and difficult cleaning and degreasing tasks. The working chambers can be built for all common basket dimensions or also for special baskets of any design.

The plants can be loaded and unloaded manually or equipped with fully automatic feeding devices which allow unmanned operation for up to several hours.

One of our specialties is the cleaning of optical components.

Many tasks in the optical industry have already been realized by us with different cleaning media. EVT systems of several series are used by well-known companies in this industry.

We would like to invite you to visit our factory in Sternenfels. Here we can explain details in practice, discuss initial approaches to realization and carry out cleaning tests in our technical center.

A large number of EVT systems are already in use in aircraft, helicopter and engine technology.

In most cases, the GIGANT system type is used with correspondingly large working chambers, where the size of the working chamber depends on the size of your components.

The degreasing of engine parts, honeycombs for stabilizing wings, rotor blades, landing gear parts, etc. requires very special options above and beyond the standards of a mature process technology in order to perfectly treat even critical and difficult-to-clean zones of the parts. Safety and quality are always our top priorities.

The treatment of pipes, with a focus on degreasing the interior of the pipes, has been a specialty of EVT for many years. By using the proven vertical oscillation, both short and long tubes can be cleaned effectively.

Another innovation is our solution for the degreasing of tube coils.

For the cleaning of tube coils, there are different possibilities of connections, so that different inner diameters can be processed in one system. Also the outside cleaning of the tubes can be combined with the inside cleaning within one plant. We have experience for lengths up to 3 km.

EVT systems cover the wide range of cleaning and degreasing tasks in stamping and forming technology.
The special requirements and needs of the individual case are the first step in designing the right degreasing system with all the necessary additional equipment. The next step is to select the right cleaning and degreasing medium.

Our sophisticated process technology guarantees that even complicated parts with unusual geometry and undercuts are perfectly cleaned. After degreasing, our drying processes ensure rapid drying of the parts and speedy decontamination of the working chamber to enable the fastest possible batch times.

Contract degreasing is confronted with rapid and diverse changes. From one day to the next, different dimensions, weights or other changed properties of the components can occur.

Here, systems with large working chambers that can withstand plenty of weight and have numerous cleaning options are in demand. Flooding, spraying, turning, vacuum distillation, chip filters, etc. are standard in these applications.

Our many years of experience as a reliable partner to contract manufacturers, makes our plant technology highly suitable for your requirements.

The heat treatment of metals requires a perfect degreasing of the parts to be hardened.

Similarly, the glowing steel or cast iron parts are quenched in an oil bath. Following this procedure, the removal of the oil from the part is required in any case. The EVT-GIGANT machines are partly especially designed for this process step before and/or after hardening.

Batch weights of up to 14 tons have already been realized here.

The advantage of non-flammable solvents, such as CHCs (chlorinated hydrocarbons), is that the curing oven and cleaning system can be located in the immediate vicinity of each other. In this way, the available space in the production hall can be optimally utilized.

EVT plants can be loaded in different ways: Rail car, robot, manually, automatically or with an ant.

The cleaning of plastics and adhesives poses particular challenges to the production process.
These substances are usually extremely stubborn and difficult to remove. The solvent methylene chloride is regularly used here, which is not as uncomplicated to handle as some other substances.

We not only have years of experience in handling methylene chloride, but have also developed a new process for cleaning agitator containers in which plastics and adhesives are mixed.

The components to be cleaned in electrical engineering mostly consist of small and smallest parts, very different shapes and geometries, and thus go hand in hand with correspondingly different requirements for the cleaning and degreasing processes.

We built a VARIO-L for a company operating throughout Europe in this sector, which degreases up to 864 baskets per day in two working chambers. A very special requirement for this project was the degreasing of the parts in closed shearing boxes. The system is loaded via a three-lane loading device that guides the baskets under a reading bridge with basket detection on their way to the two independently operating working chambers. As the baskets pass, the selected programme is read from a plasticised exchangeable chip and passed on to the control system, which feeds the baskets to the next available working chamber and cleans them accordingly.

The system meets all the customer’s specifications and even exceeds them in terms of throughput per hour: degreasing in closed shearing boxes, basket loading and unloading at the same place, up to two hours of unmanned operation, throughput of 36 baskets per hour.

We look forward to meeting your challenges.

Our VARIO is used i.a. for cleaning dental implants and our GIGANT successfully degreases joint implants.

The result of the project work and the joint exchange is presented in the form of individual and affordable special systems which, thanks to their needs-based configuration, enable the high standards of the industry to be met in the long term in a process-safe manner.

Surfaces can only be “refined” if they have been perfectly degreased beforehand.
