Your benefit: Outstanding cleaning results

  1. Operation of the complete solvent processing system under vacuum (< 100 mbar), thus offering the possibilityto work during both, flood washing and vapor degreasing above the flash point of the solvent (concernshydrocarbons and modified alcohols).。
  2. Outstanding cleaning and drying results even on parts of difficult shape.
  3. Heating of the working chamber by means of solvent vapor for a better cleaning quality of vapor degreasing andmore effective drying, with heat recovery and enhanced distillation capacity.   
  4. Pressurefloodingvianozzlebars.
  5. Power-Sonic-Cleaning (PSC): Simultaneous operation of ultrasonic (optionally) and circulation flooding at highertemperatures.
  6. Immersion cleaning with temperatures up to 95°C. Thus higher quality of degreasing and more efficient drying
  7. Vapor degreasing without vacuum reduction. Thus constant process over predefined parameters.

Your benefit: High flexibility for the future

  1. Operation of the machine alternatively with hydrocarbon solvent or modified alcohol.
  2. System extensible for the use of chlorinated solvent or reverse anytime

Your benefit: Outstanding economic efficiency

  1. Less operating effort by fully automatic processes like e.g. filter drying.
  2. Visualization is standard equipment thus easy operation of the system.
  3. Fast and user friendly sampling for media monitoring during machine operation by means of sampling units installed at all necessary tanks (e.g. flood tanks, evaporator, distillation, water separator)
  4. Integrated solvent preparation by continuous distillation. Possibility to connect an additional (enhanced) vacuum distillation (continuous oil drag-out)
  5. Little space requirement due to compact machine design.
  6. Heating of the flood tank by means of solvent vapor with heat recovery.
  7. Heat insulation of all tanks, thus less heat transfer to environment.

Your benefit: High process reliability

  1. TRIPLE-Filtration System: (grid in work chamber, swarf filter for pump protection and fine filter). Thus reducedfilter costs and less abrasion of pumps and valves.
  2. Filling and emptying of the work chamber via fine filter.
  3. Bypass filtration of the flood tanks via fine filter selectable.
  4. Separation of low and high boiling point substances by means of a fractionated distillation, thus constant solvent quality, no influence of the boiling point (valid for hydrocarbons and modified alcohols) and longer lifetime of the solvent
  5. Chiller system for condensation of the solvent vapor equipped with secondary loop (brine cooling system), for more cooling capacity and safety in case of a chiller breakdown. Because of cooling temperatures > 0 °C, there is neither ice formation nor acid formation on the condenser surface. Thus there is no need for deicing of the condenser like on systems with direct injection of the refrigerant.
  6. Tanks, condensers and solvent pipes are made of stainless steel, welded with inert gas
  7. Automatic drag-out of water and other low boiling substances.
  8. Automatic request (machine message) for execution of essential maintenance op-erations.
  9. Indirect heating via steam tubes, no steam bottom. Due to minimized dirt deposits on heat transfer surfacesoptimized heat transfer to the solvent.

Your benefit: Optimum safety

  1. Generally indirect heating of the solvent with hot water, maximum temperature on the heating device surface <160°C, thus explicitly below ignition temperature of the solvent (no additional source of ignition).
  2. TWIN-SAFETY-GUARD: Safety monitoring of solvent flashpoint and vacuum in re-dundant design by hardware (explosion proofed) and software.
  3. Automatic emptying and drying of filters, thus less solvent contact during change of filters and prevention of an explosive mixture
  4. Monitoring limit position of all safety relevant valves and flaps
  5. Additional exhaust condenser after vacuum pump for circulation condensation and reduction of the solvent emission.
  6. Integrated floor pan, visible due to base structure with leakage sensor.
This is a compact, automatically operating cleaning system, which meets highest requirements concerning cleaning / degreasing results, drying results, flexibility, environmental friendliness as well as economic efficiency.
The system works completely under vacuum. The system can be operated with organic solvents like hydrocarbons (AIII) or modified alcohols.
