The answer to the highest requirements for degreasing and cleaning marks free

SOLvent VACuum System

Abbreviation of SOLvent VACuum System , the SOLVACS vacuum degreasing machine meets the highest requirements for marks free cleaning / degreasing and drying performance.

  • Chamber heating by steam

  • Immersion degreasing up to 203°F (95°C)

  • Ultrasons and active immersion simultaneously

  • Steam phase degreasing

  • Anti-corrosion protection by immersion

  • Intensive vacuum drying

Vacuum solvent and hybrid solvent degreasing machine work chamber

Fully vacuum

The entire system in contact with the solvent (<100 mbar) works under vacuum to make it possible to clean at a temperature above the flash point of the solvent in both immersion and steam phase.

For 3-shift operation, the machine incorporates a thermal cooling exchanger by a secondary circuit to increase cooling capacity.

Optimal Safety

The TWIN SAFETY GUARD system performs continuous monitoring of solvent flashpoint and the vacuum level via a dual safety (hardware and program).

  • Indirect heating of the solvent

  • Draining and automatic drying filters

  • Monitoring all valves and check valves

  • Condensation of air discharges to reduce solvent emissions

  • Retention tank with sensor

Industrial parts cleaning and degreasing machine maintenance

Custom-made chamber

The SOLVACS vacuum degreasing machine is available in 5 different sizes, depending on the dimensions and the volume of the parts to be processed.

For special applications, the work chamber can be custom-made.

Continuous distillation

More than a degreasing machine, SOLVACS incorporates continuous distillation of the solvent to ensure optimal life and repeatable results.

In addition to that, an additional distillation minimizes the solvent content (<10%) in the waste being discharged.

Water and other substances are automatically removed at low boiling temperatures by the desaturation process.

HYBRIDE > Solvent + Aqueous Solution

The SOLVACS Hybrid provides marks free cleanliness by combining the action of solvent and aqueous solution to remove organic and mineral dirt.

This is particularly the case for vacuum deposits processing operations (plasma, nitration, etc.).

This system eliminates all types of organic and non-organic contaminations, with total compatibility of materials from the parts to be processed.

Hybrid process for industrial parts cleaning

Process reliability

HEMO GmbH as the inventor of the technology has complete control of the process.

  • Automatisation of each process steps

  • High level of equipment as standard

  • TRIPLE filtration system

  • Filling and draining the work chamber by fine filtration

  • By-pass filtration

  • Tanks, condensers and pipes welded under inert gas

Manual or automatic flow

Manual loading > manual transfer of the load to the work chamber from a table 1 or 3 positions.

Automatic loading > transferred from a roller conveyor, the load is lifted and loaded automatically into the machine chamber.

At the start of the cycle the door is closed and locked automatically.
