A valued client from the automotive coating industry visited our factory today to conduct a full simulation test of waste super fast-drying thinner with our vacuum solvent recycling equipment, achieving impressive recycling and cleaning results that fully satisfied the customer’s production demands.
1. Test Raw Material & Weight Data
The customer brought waste super fast-drying thinner generated from automotive painting and parts cleaning processes for on-site distillation recovery testing. We recorded full weight data throughout the whole trial:
- Original waste solvent drum gross weight 1: 23.75 KG
- Original waste solvent drum gross weight 2: 24.10 KG
- Total recovered clean solvent output: 35.90 KG
- The gross weight of two waste solvent drums is 47.85 KG, with a tare weight (empty drum) of 2.5 KG, so the net weight of waste super fast-drying thinner fed into the machine is 45.35 KG.
The total regenerated solvent includes 35.90 KG of collected clean solvent plus around 2 KG taken out for on-site cleaning test, barrel rinsing and sample storage.
The comprehensive solvent recovery rate of this on-site test reaches approximately 83.57%.

The clear, transparent regenerated solvent after distillation formed a stark contrast against the original dark, contaminated waste thinner, visually verifying our equipment’s strong impurity separation capacity.
2. Continuous Stable Distillation Process Recording
Our technical team tracked and documented real-time working parameters every 15 minutes during the entire recycling cycle, including heating oil temperature, vacuum negative pressure, steam temperature, flow status and distillate quality:
- The machine ran stably under segmented temperature control from 36°C up to a maximum heating oil temperature of 176°C, with steady negative pressure maintained around -0.001MPa.
- Continuous fine, smooth distillate outflow was sustained for long periods with no surging or blockage.
- Impurities like paint sludge, resin glue and metal dust were fully intercepted and left in the residue tank after recovery.
All operation data was logged in our official JBETEP solvent recycling test report, forming complete traceable records for the customer’s reference.
3. Customer Field Verification: Regenerated Solvent Matches Virgin Thinner
Midway through the recovery trial, the customer immediately took the freshly recycled clear solvent for on-site cleaning tests on metal automotive workpieces:
- Degreasing and oil stain removal for stamped metal parts
- Resin glue and coating residue stripping cleaning
After practical use, the customer gave highly positive feedback: the cleaning power, volatilization speed and surface finish effect of our recycled solvent are nearly identical to brand-new purchased fast-drying thinner. There is no negative impact on subsequent painting adhesion and surface quality, which can directly replace virgin solvent in daily workshop production.
4. Core Advantages for Automotive Coating Factories
- High recovery yield: Distillation removes paint slag, pigment, heavy oil and resin impurities thoroughly, delivering transparent, reusable solvent.
- Low operating cost: Massive cuts on virgin thinner procurement expenses, while hazardous waste disposal volume and fees are greatly reduced.
- Wide compatibility: Our TE-series vacuum solvent recycler adapts to various automotive coating chemicals, including fast-drying thinner, cleaning solvent, PMA, ester solvents and hydrocarbon wash liquid.
- Safe & low-maintenance full design: Explosion-proof configuration, automatic temperature & overpressure protection, easy residue discharge after cooling down below 60°C.
5. Customer Intention & Market Outlook
The automotive coating customer recognized our equipment’s stable performance and outstanding recovery quality after the whole on-site simulation test. They will evaluate the recycling data and formalize equipment procurement plans to realize closed-loop solvent circulation in their painting workshop.
