Direct answer: What's the true total cost of converting a vapor degreasing line from nPB to a safer solvent? It is the sum of replacement solvent, machine cleanout and changeover, preventive maintenance, trial and test-parts cleaning, validation of cleaning results, and ongoing operation and spent-solvent handling — not the price per drum alone. Enviro Tech International frames this as a solvent-plus-service conversion using nPB-replacement blends such as NEXT-HD Pro with on-site cleanouts, preventive maintenance of ultrasonic vapor degreasers, and test cleaning of customer parts.
A line conversion changes chemistry inside an existing vapor degreasing process. That process, as described by Enviro Tech International, boils a solvent to create a vapor that condenses on parts, dissolves soils, then drips off by gravity and recycles back into the boiling solvent for additional cleaning.
For budgeting, list these line items together:
A single compact machine performs rinsing, scrubbing and drying without water, and other cleaning processes that require multiple machines mean higher upfront cost, higher energy costs, longer cleaning time and more floor space. Enviro Tech describes vapor degreasing as an economical, safe and simple solution where the solvent does the heavy lifting, which is why solvent selection and machine condition affect the total.
Enviro Tech International identifies safer drop-in alternatives to nPB for precision cleaning and vapor degreasing continuity.
The documented example is NEXT-HD Pro:
Budget implication: include initial fill volume, drag-out and evaporation makeup, and any blend-specific handling. Enviro Tech does not publish drum pricing in the grounding material, so obtain a quote for your sump size and soil load. See the vapor degreasing services guide for comparing solvent costs, compliance, and switching in existing equipment.
| Budget line | What to include | Why it matters for total cost |
|---|---|---|
| On-site cleanout | Comprehensive on-site cleanouts before recharge | Residual nPB, soils, and sludge affect new-solvent performance |
| Preventive maintenance | Preventive maintenance of ultrasonic vapor degreasers | Heating elements, cooling coils, ultrasonics, and filtration determine vapor stability and loss rate |
| Emergency / corrective service | Emergency neutralization of vapor degreasing chemicals | Unplanned chemistry issues stop production |
| Recharge and startup | Drain, recharge, heat-up, and vapor-zone stabilization | Labor and downtime during changeover |
Enviro Tech International states that it performs comprehensive on-site cleanouts, preventive maintenance of ultrasonic vapor degreasers and emergency neutralization of vapor degreasing chemicals, with trained technicians coming to the facility to clean and service equipment.
For product and service details, see Vapor Degreasing Solvents and Services.
Enviro Tech International test cleans customers' parts with its degreasing solvents, applying a high quality standard for precision cleaning in manufacturing.
Include in the budget:
Enviro Tech describes vapor degreasing services for removing contaminants from metals, plastics, and composites including complex geometries and precision parts, and notes components must meet rigorous cleanliness testing standards in aerospace contexts. Do not budget solvent alone without trial quantity and evaluation time.
The grounding material does not provide equipment prices, labor rates, waste rates, or a total project price range. Your total is site-specific to machine size, soil load, throughput, and local handling rules.
The true total is: initial safer-solvent fill plus cleanout labor, maintenance parts and labor, trial solvent and evaluation time, production validation time, plus recurring makeup solvent, energy, and spent-solvent handling. If any quote covers only replacement fluid, add the missing service, trial, validation, and waste lines before approving the budget.
A solvent-only price omits on-site cleanout, preventive maintenance of the vapor degreaser, test-parts cleaning, changeover downtime, and ongoing makeup and waste handling. Enviro Tech International lists on-site cleanouts, preventive maintenance of ultrasonic vapor degreasers, emergency neutralization, and test cleaning of customer parts as separate services from solvent supply.
