Liquefies solvent-free waxes, oils and release agents directly in the gun — in the heated 0.4 l cup and the heated nozzle, up to 95 °C — and sprays them without pre-melting. The gun weighs 1050 g KUNDE: clarify — empty / with cup / with hose package; figure appears on the website only and runs on 40 V safety extra-low voltage from the control unit.

Solves your problem if …

  • You process solvent-free waxes, oils, oil-wax combinations, release agents or greases that are pasty or solid at room temperature and melt at 95 °C or below. KUNDE: Media approval taken from the 2011 manual (previous model) — does it apply to the Duoline 2.0? liability-relevant
  • You work in cup quantities: 0.4 l per filling, refilling during operation. For continuous demand from tank and hose: hot wax pressure tank system.
  • You have compressed air at 0.5–1.5 bar at the workplace and 230 V (or 110 V, optional) for the control unit.
  • You need a thin, even coat without pre-melting in a pot and without solvents — wood surface, injection mold, plastic foundation sheet, candle.
  • You want a gun the operator holds at 40 V safety extra-low voltage, not at 230 V.

Not the right choice if …

  • You want to hot-spray solvent-based paints or media. The Duoline is not explosion-proof; solvent-based media are not approved.
  • Your medium has a melting point above 95 °C.
  • You want to apply sealing wax, craft wax or hair wax — the Duoline is an industrial device with compressed-air connection and control unit.
  • You process several litres per shift without refilling or want to supply an automatic gun on a production line → hot wax pressure tank system.

Duoline 2.0 hot wax spray gun – front view with heated flow cup

How the Duoline 2.0 works

The problem: Waxes and many oils cannot be sprayed at room temperature. Cold application means rubbing on with a cloth, removing the excess and a long polishing window. Pre-melting in a pot and decanting costs time, and in an unheated nozzle the material solidifies.

The solution: The material is heated in the gun's heatable flow cup and liquefies completely. The spray nozzle is heated as well — the material stays warm until it leaves the gun, is easier to apply and spreads more evenly over the surface. Cup and nozzle heating are regulated by the control unit, set point 20–95 °C; the gun itself runs on 40 V safety extra-low voltage. Atomization uses compressed air at 0.5–1.5 bar, air cap optionally flat or round jet.

Frequently asked questions about the Duoline 2.0

Does the hot wax spray gun need compressed air and electricity?

Yes, both. For atomization the Duoline 2.0 needs compressed air at 0.5–1.5 bar working pressure (recommended). The control unit is connected to 230 V (optional 110 V) and supplies the gun with 40 V safety extra-low voltage for cup and nozzle heating. According to VISECO, air consumption is low. KUNDE: state the value in l/min — answers the question "is a small compressor enough?"

Which waxes and oils can I process, and at what temperature?

Solvent-free waxes, oils, oil-wax combinations, release agents and greases with a melting point of 95 °C or below. KUNDE: Media approval taken from the 2011 manual (previous model) — does it apply to the Duoline 2.0? liability-relevant The control range is 20–95 °C. For a specific product (manufacturer, designation), send us the safety data sheet — we will check suitability.

May I hot-spray solvent-based paints? Is the gun explosion-proof?

No. The Duoline 2.0 is not explosion-proof; solvent-based media are not approved. Only solvent-free media are approved.

Which nozzle is the right one?

Standard is 1.2 mm. For low-viscosity media and a fine coat there is 0.8 mm, for more viscous media and higher throughput 2.0 mm. KUNDE: confirm nozzle ↔ medium assignment The air cap is available as flat or round jet.

Can the wax stay in the gun after work?

Non-reactive materials can remain in the cup after use and be re-liquefied at the next use — this is how VISECO describes it in the brochure of the previous version (01/2022). Oxidatively drying oils and waxes should be flushed out. The gun is designed for simple assembly and disassembly. KUNDE: confirm this statement for the Duoline 2.0; cleaning recommendation in two sentences

How much wax does a surface need?

The trade press quotes approx. 10 g/m² for the hot wax process of the predecessor company MK Heißwachstechnik (BM online 07/2000). KUNDE: confirm the current guide value for the Duoline 2.0 — otherwise delete the question; not in the FAQ schema until then

Can waxed parts be stacked immediately?

VISECO makes no statement of its own on this. Users report it in a forum (woodworker.de, 2010), and the wax manufacturer AURO states for its hard wax no. 171 in the hot-spray process that it can be polished within one hour instead of 1–2 hours with cold application. KUNDE: release a statement of your own or delete the question; not in the FAQ schema until then

What is the difference between the Duoline 2.0 and the pressure tank system?

The Duoline is the cup solution for manual workstations, the hot wax pressure tank system the tank solution for continuous demand. Material reserve, hose, guns and use are listed in the comparison on this page.
