Compressed air and material heating for paint spraying
Atomizing air and coating material are heated right at the point of spraying – at the spray gun and in the airless hose.

Compressed air heater
Airtherm
Heats the atomizing air directly at the spray gun instead of in the line – finer atomization at lower pressure, less overspray, shorter drying time.
20–100 °C, up to 500 NL/min; material savings of up to 30 % according to the brochure; ATEX version
Heated airless hose
WarmUp
Heats the material in the airless high-pressure hose to up to 60 °C – lower viscosity, lower spraying pressure, consistent application even in cold weather.
15 m or 30 m, up to 230 bar
Applications
Automatic surface spraying machines
Integration of the Airtherm in the machine; additional heating for the atomizing air without modifying the material side.
Spraying robots
Installation at the robot atomizer; hose length freely selectable.
Manual spray gun applications
As additional heating: only the air hose is replaced.
Airmix process
Heated atomizing air with air-assisted airless.

Fewer filter changes: "An added advantage of the lower spray losses is that the load on the intake filter is reduced so that it needs to be changed less often." → Andreae paint booth filters
Two Airtherm units on one gun: atomizing and fan air heated separately.
Frequently asked questions
My compressed air is too cold – can I heat the atomizing air?
Yes. That is exactly what the Airtherm is built for. It replaces the air hose of the existing spray gun and heats the compressed air as a flow-through heater directly at the atomizer to the set point (control range 20–100 °C). The cooling of the spray head below 5 °C that compressor air otherwise causes is eliminated.
How quickly is the material warm, and what temperature does the hose reach?
According to VISECO, the preheating phase is approx. 2–4 minutes. The control range goes up to max. 60 °C; the actual material temperature depends on the flow volume. The set point is set on the temperature controller.
What does heated atomizing air do for painting?
According to VISECO: lower atomizer pressure, less material and air consumption, finer atomization and therefore shorter drying times, more coating thickness per operation, a significantly higher runner limit and a constant working temperature in any environment. The brochure (01/2022) states as manufacturer's figures up to 30 % material savings, up to 180 l/min less air and up to 8 dB less noise – measuring conditions are not stated there.
Which length, which pressure, which power?
Two versions: 15 m (DN06, 1/4", 1.5 kW, max. 6.5 A, article no. 140-107-15) and 30 m (DN10, 3/8", 2.1 kW, max. 9 A, article no. 140-107-30). Both up to 230 bar material pressure, both 230 VAC. Other lengths on request.
