3.1 Intended use
The Fluid Heater can be used, according to version (HP or LP), in
high- or low-pressure applications for heating the applied materials and/or the
compressed air supply.
The following types of coating materials may be heated:
➤ Paint and lacquers
➤ Protective coatings (oil and grease)
➤ Stripping agents
➤ Insulation and fire-protection coatings
➤ Tar-epoxy and bituminous paints
➤ Polyurethane
➤ Water
3.1.1 Models 1800 and 3500 HP
Max. operating pressure: 450 bar / 6525 psi
The
High-Pressure Fluid Heater is especially suitable for use with Air-
less spraying systems, Airless plural component units und Air Combi systems.
The advantages of the hot-spray process include higher coating thickness,
shorter drying times and top-quality finishes.
Coating materials which are normally difficult or impossible to process due to
their consistency become easily sprayable when warmed up using a
Fluid Heater.
With the addition of a mounting kit, the fluid heater can simultaneously be
used for heating of the compressed air supply:
a) as pre-heater for a
air motor, to prevent icing caused by low out-
side temperatures and high humidity.
b) for the heating of the atomizing air for Air-Combi systems. Through ad-
ditional heating of the atomizing air, the quality of the finish is improved
further and the drying time is shortened.
3.1.2 Model 3500 LP
Max. operating pressure: 200 bar / 2900 psi
The
Low-Pressure Fluid Heater is suitable for heating materials to be
applied in low-pressure processes.
Futhermore, the
Low-Pressure Fluid Heater can be used for the sup-
ply of heated air to the air motor (de-icing) or for preheating materials being
fed to plural component spraying systems.
