Hot wax technology: liquefy the material inside the unit and spray it
Waxes, oils and release agents are melted in the heated unit and sprayed directly – no pre-melting, no solvents.

Hot wax spray gun
Duoline 2.0
Liquefies wax, oil or release agent in the heated 0.4 l cup and sprays it directly – no pre-melting, no solvents, the material can stay in the cup.
20–95 °C, 1050 g – 30 % lighter than the previous model
Heated material supply for spray guns
Hot wax pressure tank system
Supplies one or two manual or automatic spray guns from the heated 12 l pressure tank through a core-heated hose – the material stays in the system, no flushing.
12 l / 24 l, up to 95 °C, up to 2 spray guns

| Feature | Duoline 2.0 | Hot wax pressure tank system |
|---|---|---|
| Material supply | 0.4 l cup on the gun | 12 l pressure tank (24 l optional) |
| Hose | Hose package gun–control unit (carries air and 40 V) KUNDE: heated/unheated? | core-heated material hose 7.5 / 10 m |
| Guns | 1 manual gun | 1–2 manual or automatic guns |
| Use | Cup quantities, mobile, manual workstation | Continuous demand, stationary system, automatic spraying machine, robot |
| Downtime | Material in the cup KUNDE: confirm for the 2.0 — documented only in the brochure of the previous version 01/2022 | Material stays in tank and hose and is re-melted |
Both systems share the same media approval (solvent-free, up to 95 °C). Whether the Duoline 2.0 gun itself can be operated on the pressure tank is not documented. KUNDE: clarify
A small spray booth for trials and sample production captures the spray mist: small spray booth.
Whether the Duoline 2.0 gun can be operated on the pressure tank is not documented. KUNDE: clarify Whether the Airtherm preheats the atomizing air for the pressure tank system is not documented. KUNDE: clarify — the Airtherm brochure mentions only material hose + double diaphragm pump
Automation: For automatic spraying machines and robots the system supplies the material; according to the Airtherm page, Airtherm air heaters are integrated in automatic surface spraying machines and installed in spraying robots. → Airtherm compressed air heater
Frequently asked questions
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?"
Does the system have to be flushed daily?
No. After use the wax stays in the system and is re-liquefied at the next use, both in the tank and in the material hose. Time-consuming flushing and cleaning is hardly necessary any more.
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.
How long does it take until the system is ready for operation?
According to the brochure, the preheating phase is approx. 15–20 minutes. KUNDE: does this apply to 12 l and 24 l, at which filling level and target temperature?
