Chlorinated solvents systems (hermetically sealed process)

The range of chlorinated solvent machines for metal cleaning, which are in our production program since almost 50 years and object of an ongoing renewal process, is split-up into two sub-ranges  all operating with the hermetically sealed process : series Logica-SF-E that exploit the  super-stabilised perchloroethylene and the models that exploit methylene chloride or special solvents (hydro-fluorocarbons, HFE, etc.).

Still today, in the majority of cases, the systems of this range exploit super stabilised perchloroethylene that has an  high solvent power and it is compatible with most metals, especially those that oxidise easily, such as aluminium, magnesium, zinc and alloys such as brass and other.

FUNCTIONALITY: Ideal to remove pollutants such as processing oils, chips and micro dust on different types of materials (brass, steel, iron, aluminum, zinc alloy, precious metals). Also, the Logica-SF-E ranges  are ideal for the cleaning of polishing pastes polluted components.

PRODUCTIVITY: The washing cycles can be programmed for both functions and time according to the specific needs of the operator.

MAXIMUM EFFICIENCY: low consumption of the product thanks to continuous distillation and high energy savings achieved through innovative design, privileging the complete hermeticity.

SAFETY: Maximum safety for operators and for the working environment due to sophisticated control systems of temperatures, pressures and of all the devices of the system. Warranty of use in complete safety. All our plants are built in full compliance with local environmental law.

Perchloroethylene – Methylene chloride –  Hydro-fluorocarbons

Upon request customized and larger chamber versions, with Top Loading, are available 

 Systems designed and built to work over 3 shifts

• Reduced electrical consumption thanks to the “Energy Saving Device”  (the distillation heat is recycled to heat the solvent in the tanks).
• Ample possibility of employing a variety of different chemical  additives enhancing the component features
• Optimised and safe operation of the systems thanks to the fact that the main physical operational parameters are continuously monitored by the Siemens ET 200 SP PLC
• Distillation system with single or double still (also under vacuum).
• Basket drive by means of a gear motor managed by an inverter and encoder.
• Improved technical assistance thanks to the rational arrangement of the machine’s components
• Continuous monitoring of the vacuum seal, thus minimising emissions and risks.
• Exposure limits of operators are well above the emissions of the system, which complies with all standards, even the strictest.
• Possibility to fill and discharge residues without vapour emissions in the workplace.
