As manufacturing shifts towards smaller batch sizes and more frequent production runs, component cleaning systems must deliver higher cleanliness standards while remaining economical and resource-efficient. Karl Roll’s new Focus solvent cleaning system has been developed specifically to meet these changing requirements, combining reliable cleaning performance with a compact footprint and low operating costs.

Cost-effective solvent cleaning 

Designed as a cost-effective entry point into high-quality solvent cleaning, the fully enclosed system offers the essential technologies required to achieve demanding cleanliness specifications without the complexity and expense of larger installations. Operating under full vacuum and compatible with both hydrocarbons and modified alcohols, the Focus accommodates components measuring up to 565 x 365 x 250 mm and weighing up to 50 kg, while requiring only an industrial power supply and compressed air connection.

The system features two flooding tanks with separate media cycles, including an option for part conservation.

Pump performance at its core

A key feature of the Focus system is its integrated pump technology, which plays a critical role in both cleaning performance and process efficiency. The machine is equipped with two solvent tanks, each operating with its own media circulation system and bypass filtration.

For applications requiring exceptionally high cleanliness standards, the tanks can be configured for pre-cleaning and fine cleaning stages. Alternatively, users can dedicate one tank to cleaning and the other to conservation processes.

Supporting these configurations are two powerful pumps that ensure rapid evacuation of the working chamber, accelerating cycle times and improving overall process efficiency. By enabling fast and effective solvent transfer, the pumps help maintain stable cleaning conditions while supporting repeatable, high-quality results. The system is further enhanced by integrated ultrasonic cleaning, with frequencies adjustable to suit specific application requirements.

To improve operator ergonomics, the Focus includes a loading aid as standard, with options for automated loading and unloading systems. For manufacturers seeking unattended operation, a barcode scanning system is also available.

Integrated ultrasonic elements ensure reliable, repeatable, and resource-efficient cleaning performance.

Energy-efficient operation 

Karl Roll has placed particular emphasis on minimising operating costs through careful selection of key system components, including the vacuum pumps and drain pumps. These have been chosen to deliver an optimum balance between performance and energy consumption, helping users maintain low running costs without compromising cleaning quality.

The Focus also incorporates the company’s proven solvent management technology. An integrated distillation unit continuously processes and purifies the cleaning medium, while an automatic oil discharge system removes distilled oils, keeping the solvent cleaner for longer and significantly extending its service life.

Additional energy savings are achieved through heat recovery from the distillation process and effective insulation of all heated media. Together with the energy-efficient pump systems, these measures contribute to a highly economical operating profile.

Particulate contamination is captured through an integrated filtration system, while an optional automatic lid-lock mechanism prevents solvent emissions during filter changes by ensuring the filter housing remains securely sealed.

A practical solution

By focusing on the technologies that matter most, particularly efficient pumping systems, solvent management and process stability, the Karl Roll Focus delivers a compelling solution for manufacturers facing lower throughput requirements but higher cleanliness expectations. Combining reliable cleaning quality, low resource consumption and excellent value for money, the system is well suited to the demanding cleaning of precision and small components where efficiency and consistency are paramount.
