PERO – Technological Milestones

Introduction of revolutionary refrigeration technology in parts cleaning, reducing solvent consumption by 50%.

Development and manufacture of water-based cleaning units – the popular ROBOMAT is born, replacing steam jet cleaners in maintenance shops.

Launch of first front-loading machines for industrial parts cleaning. This loading method has since become the standard in hermetically sealed cleaning units.

PERO wins the German Innovation Award for its innovative integrated treatment system for solvents.

PERO sets the standard for German Federal Emission Control Act
When setting the permissible limits for solvent consumption, the German lawmakers apply the innovative, hermetically sealed systems from PERO as the new standard.

PERO units provide excellent cleaning results despite FCHC ban
In response to the FCHC ban, PERO develops a proprietary refrigerant that fully conforms to the new regulations.

With the PERO V1, the company launches its first water-cooled vacuum degreasing system. All machine sections containing solvent are operated under vacuum. The unit is continuously monitored for leakage, while the cleaning processes are performed at temperatures that are significantly lower than with conventional machines. This protects not only the parts, but also the cleaning medium.

PERO developments revolutionise explosion protection regulations
In contrast to plant manufacturers who consider underpressure as sufficient to prevent explosion in parts cleaning plants operated with hydrocarbons, PERO offers units with qualified explosion protection.

Extension of PERO's V series with new models from V0 (typical batch size: 380 x 220 x 200 mm) to V5 (for Euro wire mesh boxes).

Launch of "Universal" cleaning unit
The new "Universal" cleaning unit can be operated with modified alcohols, hydrocarbons (flash point > 55°C) or halogenated hydrocarbons. Changing cleaning medium is extremely quick and easy, and requires no mechanical modifications.

Launch of PERO R1, the first model of the R series, the successor of the V series. The R1 revolutionises parts cleaning, as it is the fastest cleaning unit in its batch-size class. Cycle times are virtually halved, while throughput rates are nearly doubled. Greater technical cleanliness can already be achieved with the standard model. Automated filter-drying, automated oil discharge and a range of maintenance programmes make the unit particularly user-friendly and cost-efficient.

The PERO R2 is launched, replacing the PERO V2 model. Thanks to its novel design, the R2 sets new standards, as it allows for much higher throughput rates at reduced energy consumption, thus significantly reducing the cleaning costs per part.

PERO launches the S1, an entry-level unit for parts cleaning with solvents.

PERO celebrates 60 years of INNOVATION
PERO offers a comprehensive range of wet cleaning units run with water-based media, and for operation with modern solvents. The PERO portfolio covers everything from manual on-the-spot cleaning devices, turn tables and chamber units to powerful high-tech plants for large batches and deep cleaning.

Launch of PERO R4 and PERO R5 models, replacing the V4 and V5 respectively.

The new R0 model for parts cleaning with solvents is the latest model of the R series that now replaces the entire V series.

With the NEPTUN, PERO adds another innovative model to its water-based parts cleaning unit range.

PERO introduces an automatic shift function for its R0 to R5 models, providing unrivalled user comfort in parts cleaning with solvents.

With the completely redesigned, extra compact automatic charging unit for the R1 model, PERO offers an enhanced loading and positioning system for parts carriers.
