DISTATIC
Di · static version
For liquids for which processing without a scraper is suitable. Depending on the residue, a Rec-Bag is used or the kettle is emptied by tilting.
FORMECO / SOLVENT DISTILLERS AND EVAPORATORS
More useful.
Less residue.
FORMECO distillers for solvent regeneration and evaporators for water-based process fluids and emulsions. The technology is selected according to the fluid composition and the target of separation or reuse.

SPECIALIST IN LIQUID SEPARATION
FORMECO.
Since 1971.
The Italian manufacturer develops and produces solvent distillers, process water evaporators and fractional distillation systems. Its solutions are used in surface treatment, paint and printing ink production, metalworking and other industrial processes.
Equipment selection is supported by its own laboratory and pilot units. This allows the actual fluid to be tested before deciding on the size and version of the plant.
About the manufacturer and technology development ↗UNDERSTAND THE PROCESS
What goes into the machine.
What we get out of it.
The solvent or water evaporates and then condenses. Less volatile components remain in the concentrated residue. The equipment and process settings are adapted to the incoming fluid.
Water-based process fluidVacuum evaporatorCondensation
INLET
For example, used oil emulsion or wash water from production.
SEPARATION
At reduced pressure, water evaporates at a lower temperature. The resulting vapour is cooled and condensed.
RESULT
The aqueous fraction is collected as distillate; oils and other less volatile components concentrate in the residue.
Simplified illustration of the principle. The quality of the distillate, the proportion of liquid removed and the handling of the concentrate are checked for the specific mixture.
01 / SOLVENT REGENERATION
Solvent from washing or degreasing.
Ready for a new use cycle.
Distillation separates suitable solvents from resins, pigments, paints, oils and other less volatile residues. The solvent is heated via a jacket with thermal oil, and the resulting vapour is condensed by air or water cooling.
DYNAMIC
DiQ · scraper version
An internal scraper moves the contents and reduces residue sticking to the walls. The version is selected according to the behaviour of the liquid during concentration.
| Data | Di 30 Ax LCD | DiQ 60 Ax LCD |
|---|---|---|
| Useful fill | 30 l | 60 l |
| Total kettle volume | 43 l | 103 l |
| Internal scraper | No · static version | Yes · dynamic version |
| Connected load | 2.04 kW | 4.2 kW |
| Electrical connection | 230 V / 50 Hz, single-phase | 400 V / 50 Hz, three-phase |
| Condenser cooling | Air | Air |
The data apply to the stated Ax LCD versions from the catalogues. Useful fill is not the total kettle volume; connected load is not the energy consumption per cycle.
Professional and Industrial: when you need more automation
The Professional series enables multi-stage process control and, depending on the equipment, sequential batches, automatic filling or emptying. Industrial is intended for larger quantities and for integrating regeneration into production.
The DQ 250 example has a useful fill of 250 l. The DQ 250 Wx catalogue lists water cooling of the condenser, a connected load of 16 kW and a three-phase 400 V / 50 Hz connection. Versions and additional equipment are agreed with the manufacturer.
For solvents with a higher boiling point, a suitable vacuum version may be appropriate. Explosion protection requirements, seals and temperatures are checked according to the fluid safety data sheet.
FORMECO · industrial versions ↗02 / WATER PROCESS LIQUIDS
Production water can also
be reusable.
Used washing and rinsing water, cooling lubricating emulsions and other water-based liquids contain various impurities. FORMECO offers evaporators and concentrators for their treatment.
Vacuum evaporation with a heat pump
The HP series operates at reduced pressure. The heat pump provides heat for evaporation and cooling for condensation. This produces two separate streams: water distillate and concentrated residue.
HP-S · emulsions and less deposits
Immersed heating exchanger. For suitable oil emulsions and liquids from degreasing and die casting that do not cause significant deposit build-up.
Manufacturer programme: 10–500 l/hHP-R · liquids that form deposits
An evaporation chamber with an internal scraper helps maintain heat transfer when the residue is thickening. Suitable for water-based liquids with paints, printing inks or salts.
Manufacturer programme: 10–250 l/h| Data | HP-S 10 Opentop | HP-R 10 Opentop |
|---|---|---|
| Catalogue capacity | 240 l/day | 240 l/day |
| Installed power | 4 kW | 5 kW |
| Power consumption according to the catalogue | 1.5 kW | 2.2 kW |
| Design | Immersed heating exchanger | Internal scraper |
Data from the HP catalogue, pp. 2–3. Actual capacity and consumption depend on the liquid composition, the desired concentration and operating conditions. The photo shows the HP-R family, not necessarily the model compared.
EXAMPLE: OIL EMULSION
Water distillate + concentrate with oil.
During treatment of a suitable emulsion, water is removed, while oils and other less volatile components remain in the concentrate. This in itself does not mean obtaining clean oil for reuse. The required water quality and any additional treatment are determined according to its subsequent use.
SMALL QUANTITIES / CONCENTRATION
Ci and CiQ.
Another route for aqueous liquids.
Concentrators with heating through a thermal oil jacket are of interest for smaller quantities and a higher required concentration of the residue. Static versions Ci and scraper versions CiQ are available.
- Example
- Ci 30 Ax LCD
- Useful fill
- 30 l
- Connected load
- 3,6 kW
- Electrical connection
- 230 V / 50 Hz
Data from the concentrators catalogue, p. 3. The selection of equipment for aqueous liquids is checked separately; the Ci designation does not mean the same design as the Di solvent still.
Concentrators from the manufacturer ↗Higher flow rates and other heat sources
HP-Cf
Forced circulation of the liquid through the evaporation unit for larger daily quantities. Multi-stage versions are also available; for further concentration, the system can be supplemented with a suitable second unit.
HP-Cf programme ↗HW / HS
External heat source: hot water for HW or steam for HS. It makes sense to check this when such a source is already available in production. Versions with scraper and forced circulation are available.
External heat source ↗MVR
Mechanical vapour recompression. The compressor raises the energy level of the generated vapour, which is reused as a heat source in the evaporation process.

FROM LIQUID TO SUITABLE EQUIPMENT
We start with your process.
You describe the liquid
Which process it comes from, how much is generated and what it contains. Safety data sheets for the materials used and any available analysis help.
We check the treatment
Together with FORMECO we coordinate the need for a laboratory or pilot test and the target for the distillate and concentrate.
We agree on the version
Capacity, heat source, cooling, machine materials, automation and residue handling follow the verified process.
Are these wastewaters or process liquids?
“Aqueous process liquids” describes water-based liquids that arise or are used in production. When used up or contaminated, manufacturers often treat them as industrial wastewater. This may include washing waters and oil emulsions. Their treatment is determined by composition and by the way they are generated and used further.
Can the distillate be returned to production immediately?
Suitability is assessed according to the required quality for the next process. Some components may also pass into the distillate, so the result is checked by test or analysis. Reuse, additional treatment and handling of the residue are determined for the specific liquid.
What about separating two different solvents?
For separating liquids according to different volatility, FORMECO also offers fractionating columns. This is a special field, which we assess based on the composition of the mixture and the required separation.
Fractional distillation ↗ENQUIRY FOR YOUR LIQUID
Solvent, emulsion or washing water?
Write which process the liquid comes from and approximately how much is generated. Together we will define the next step.
