Why It Wins

Vapour degreasing, the modern way

Vapour degreasing survives in modern industry for a reason: nothing matches distilled-solvent final cleanliness on high-volume precision work. What changed is the chemistry — DOWCLENE 1601's modified-alcohol formulation replaces the legacy chlorinated solvents with a cleaner-profile fluid engineered for today's closed machines.

It belongs exclusively in sealed vapour-degreasing plant — never open tanks — where its dual character handles both non-polar oils and polar residues in one distillation-refreshed cycle.

For operations running or considering vapour plant, we supply the fluid and the conversation about the machine that closes around it.

Bath Life

This is not a single-use chemical

A common misconception treats industrial chemistry like dishwater — used once, tipped out. A defended bath of DOWCLENE 1601 works for weeks of production: the oil-splitting formulation sends released oils to the weir, solids leave through the filter, and the chemistry keeps working until genuine depletion.

Change out on evidence, not anxiety: when cycle times stretch or results fade at correct concentration, the bath has earned its retirement. Top-ups at specification carry it between changes.

Keep It Honest
  • Skim or weir oils continuously — oil load is bath killer #1
  • Filter solids; drain settled sludge from the sump
  • Verify concentration on schedule — titration method on the product TDS
  • Log it — the trend predicts top-ups before cleaning fades
Storage

Drum and bath, both looked after

The Concentrate
  • Store cool, ventilated and sealed, out of direct sunlight
  • Segregate from incompatible chemistry and ignition sources
  • Original labelled containers only detail from SDS pending
Compliant with the product SDS.
The Working Bath

Lid the tank between shifts — holds temperature, limits evaporation, keeps dust out.

Idle periods: a warm, stagnant aqueous bath can support biological growth over extended stagnation. Circulate periodically, keep concentration at specification, never leave an open tank standing for weeks.

Extended shutdown: drain to sealed, labelled containers — or schedule changeover for restart day.

DOWCLENE 1601 FAQ

Asked at the tank

What dilution and temperature do I run?
Per TDS at working temperature — and the trial sets your exact process values against your soil. Running richer than specified wastes chemical without cleaning faster. That range is the chemistry’s window — not the whole answer. The substrate sets its own ceiling, and it is usually lower: aluminium and anodised finishes discolour above about 65 °C, zinc and coated parts lower again, and magnesium is governed by pH before temperature. Run at the lower of the two. Bath temperature — chemistry vs substrate →
When do I change the bath?
When cycle times stretch, results fade, or filtration stops holding the debris. Drain, clean the tank, refill — never lay fresh solution over settled sludge.
Can algae grow in the bath if it sits unused?
Over extended stagnation, any warm diluted aqueous bath can support growth as preservative systems deplete. Prevention: circulate periodically, hold concentration at specification, lid the tank. If a bloom happens: drain, clean the tank including weir and lines with hot fresh solution, rinse and refill — never dose on top of growth.
Can I get the SDS before buying?
Yes — every product ships with its SDS, and documents are available ahead of purchase for your chemical register and risk assessments.

Prove it on your parts

The trial pairs DOWCLENE 1601 with your components — concentration, temperature and cycle documented before you order a drum. Wrong chemistry for your soil? The trial says so.
