| Development of the “R” series for solvent plants, size V1. This new product revolutionises component cleaning. Cycle times are reduced by almost 50%, thus capacity and throughput are almost doubled and on top of that, even more thorough cleaning of the components is achieved. | |
|
| Stepwise completion of the full vacuum plant series up to size V5. PERO now produces all its solvent plants with the full vacuum technology up to size V5. This plant has the capacity of one Euro skeleton box. | |
|
| Market launch of the first “Universal” cleaning plant. The cleaning plant type “Universal” can be operated with CHC, HC, modified alcohols, fluorinated or brominated hydrocarbons (flashpoint >55 °C). Switching of the type of solvent is possible without mechanical alterations any time and in a simple manner. | |
|
| Construction of the first full vacuum plants of size V1. With this development – for the first time, all solvent-bearing areas are operated under vacuum – PERO achieves permanent leakage monitoring of the cleaning plant and the processes run at significantly lower temperatures, which reduces the media consumption and is gentler on the components. | |
|
| PERO developments revolutionise the explosion protection regulations. While competitors of PERO consider negative pressure in plants working with hydrocarbons as sufficient explosion protection, the Königsbrunn company chooses another path: it launches systems with qualified explosion protection, and thus sets the right course: PERO’s explosion protection solution is exemplary. | |
|
| PERO plants cleaning despite CFC prohibition. Due to the ban on CFC, the refrigerant used in plants of PERO cannot be used anymore. PERO therefore develops its own refrigerant made up of permissible substances. | |
|
| PERO serves as a model in the determination of limit values. PERO ushers in a new era with solvent cleaning plants for CHC. The systems are physically closed. The extremely low consumption of the plants serves the legislators as a standard for the limit values of the German Federal Immission Control Act. | |
|
| Development of the front loader. The first hermetically closed solvent cleaning plant. The first front loader in the world for component cleaning plants is developed and launched by PERO. Today, this principle has been acknowledged around the globe as state of the art. | |
|
| Development of the closed-cycle CHC plant. The plants are provided with a facility for drying the components. The work-pieces can be removed dry and without odours. Odour nuisance from these plants is history. | |
|
| Robomat replaces steam-jet plant in repair shops ... and considerably reduces the wastewater volume. The “Robomat” manages to remove persistent contamination and burnt-in oils from the work-pieces and repair components for the first time without personnel interaction. With the cycle operation, the volume of wastewater is reduced enormously. The principle of operation of the Robomat is so successful that until today, the Robomat has been built and sold for the most varying areas of application. | |
|
| Launch of electrical refrigeration. A considerable amount of solvents is consumed by the first cleaning plants. PERO managed to drastically reduce solvent consumption by launching electrical refrigeration. |
