Machine Description

Used 2018 Union MDMV 1 industrial metal degreasing and component cleaning machine, designed for precision cleaning of small and complex metal components using super-stabilised perchloroethylene (PCE / PER / tetrachloroethylene).

This is a closed-circuit hermetic vacuum solvent cleaning system incorporating washing, rinsing, vapour degreasing, solvent recovery/distillation and vacuum drying within an enclosed process.

The machine has a maximum basket load of 50 kg and is equipped with Union Dialog control, an Industrial Frigo GR2A 30/Z industrial water chiller, and 2 x SAFECHEM SAFE-TAINER chemical storage/handling units complete with stainless steel containment trays.

Union describes the MDMV range as being specifically designed for small components and components with complex geometries such as blind holes. The machines operate under vacuum and incorporate continuous solvent distillation with automatic final stripping of residues.

This makes the MDMV 1 particularly suitable for demanding industrial cleaning applications in sectors including precision engineering, CNC machining, aerospace, automotive, medical component manufacture, toolmaking and general metalworking.

Cleaning Process & Machine Functions

The Union MDMV series is designed as an enclosed solvent-cleaning system capable of combining several cleaning processes in a programmable cycle.

The principal MDMV functions are:

• Basket rotation and oscillation
• Spray cleaning
• Immersion cleaning
• Solvent vapour cleaning / vapour degreasing
• Vacuum drying
• Integral solvent recycling by distillation
• Activated-carbon vapour abatement
• PLC-controlled operating cycles

This particular machine also has a substantial integrated solvent-management system incorporating working and recovery tanks, solvent pump, fine filtration, swarf filtration, still/distillation system, condenser, heat exchanger, separator, decanter, vacuum pump and active-carbon treatment.

Continuous Solvent Recovery

A particularly useful feature of the MDMV design is the continuous solvent distillation/recovery system.

Union states that MDMV machines operate under vacuum for rapid washing cycles and use continuous vacuum distillation with automatic final stripping of residues, allowing contaminated solvent to be regenerated and reused during production.

This gives the machine an important advantage over simple open solvent tanks or manual degreasing systems: solvent cleanliness can be maintained automatically rather than continually replacing contaminated solvent.

Union Dialog Control

The machine is fitted with Union Dialog electronic control for managing the cleaning process and cycle parameters.

Earlier Union technical literature for this machine family describes the Dialog system as allowing operators to select and modify cleaning processes including:

• Hot or cold solvent washing
• Immersion washing
• Spray washing
• Solvent vapour treatment
• Drying cycles
• Programmable operating sequences

Industrial Frigo GR2A 30/Z Chiller Included

The machine is supplied with a 2018 Industrial Frigo GR2A 30/Z air-cooled industrial water chiller.

Chiller Specification

Manufacturer: Industrial Frigo

Model: GR2A 30/Z

Year: 2018

Serial Number: 46050

Refrigerant: R407C

Refrigerant Charge: Approx. 5 kg

Electrical Supply: 400 V / 3 Phase / 50 Hz

Rated Current: Approx. 23 A

Nominal Water Pressure: Approx. 3.2 bar

Temperature Set-Point Range: -10°C to +25°C

Weight: Approx. 390 kg

Industrial Frigo data for the GR2A 30/Z indicates a nominal cooling capacity of approximately 28 kW, pump capacity of approximately 80 litres/min, approximately 3.2 bar pump pressure and approximately 170 litre internal tank capacity, depending on operating conditions and specification.

The GR2A is an air-cooled industrial process chiller designed for dedicated or centralised cooling circuits.

Also included are:

2 x SAFECHEM SAFE-TAINER chemical / solvent storage and handling units

Complete with stainless steel containment trays

The SAFE-TAINER system is specifically designed as a closed-loop solvent handling system. SAFECHEM describes the system as using separate protected containers for fresh solvent supply and collection of used solvent, reducing the handling and exposure associated with transferring cleaning solvents.

SAFECHEM states that the SAFE-TAINER system can be connected to closed cleaning machines and is suitable for handling chlorinated solvents as well as modified alcohols.

These are therefore a useful addition to the Union installation rather than simply loose chemical storage tanks.
