A vacuum solvent machine only cleans well if its vacuum, distillation and filtration are in good condition. WashTech provides preventive and corrective maintenance for HEMO, NGCT, SAMT and other-brand solvent degreasing equipment, with technicians who know this technology.
On a solvent machine, problems almost always start quietly. These symptoms mean an inspection is due before cleaning quality or production are affected.
Solvent has to be topped up often or gets dirty quickly: distillation or vapor recovery is not working properly.
Parts no longer reach the required cleanliness or come out with an oil film: contaminated solvent, filtration or vacuum drying to be checked.
The machine takes longer to reach vacuum or finish the cycle: possible vacuum pump wear, leaking seals or valves.
Stops due to vacuum, temperature or level alarms: sensors, interlocks or cycle parameters to be checked.
More frequent filter changes or lower immersion flow: filtration and bypass to be checked.
Traces of solvent in the drip tray or around the machine: address immediately for safety.
Each visit covers the systems that determine cleaning quality, solvent consumption and machine safety.
Vacuum pump, valves, seals and chamber tightness.
Evaporator, condenser and purge of the separated oil, to keep the solvent clean.
Chip and fine filters, bypass circuit and immersion flow rates.
Vacuum and temperature sensors, door interlocks and drip tray.
Solvent heating, heat exchangers and vapor condensation.
Program parameters, times and pressures of each cycle step.
Check of the result on your parts and process adjustment if needed.
Visit report with the machine condition and recommended actions.
Annual contract with visits scheduled according to your shifts and oil load. Complete inspection of the installation, adjustments and report. Fewer unplanned stops and longer solvent life.
Your machine fails or no longer cleans as it should: we diagnose, repair and restart the equipment, verifying the cleaning result.

Yes. We maintain HEMO, NGCT, SAMT and other-brand solvent cleaning machines, even if they were not installed by WashTech.
We recommend at least one complete inspection per year. The ideal frequency depends on the number of shifts and the amount of oil carried in with the parts; we define it with you in the preventive contract.
Yes. Our technicians are based in Querétaro and serve plants throughout Mexico.
Machine brand, model and year, the solvent used and the symptoms you observe. Photos of the nameplate and of the alarms on the screen help us prepare the visit.
Vacuum solvent machines normally run on modified alcohols or hydrocarbons. During the visit we also check the condition of the solvent and its distillation.
