OVERVIEW OF APPLICATION

2.1

RANGE OF APPLICATION

The heating-hoses TempSpray-H326, TempSpray-H226 and
TempSpray-H126 are designed for all established Airless paint-
spraying devices, whose operating pressure is below the rated
pressure of the heating-hoses.
With some electronically controlled Airless-
devices, the operation of a TempSpray-H126
can lead to malfunctions. To avoid this,
mount a shock absorber (e.g. a 15m meter
long textile reinforced high-pressure hose)
between the device and the heating hose.
With the heating-hoses, mainly water-based colours can be
heated from 20°C to 60°C, to improve the spraying on the
Airless-nozzle.
Thereby it is possible to improve both spray result and mate-
rial consumption. This depends on the used material and the
calibration of the parameters. The heating-hoses can be used
both in workshops and on construction sites.
Due to the cross-section and the operation length, the Temp-
Spray-H326 is adapted well for high-viscosity materials out-
doors.
Due to its shorter hose, TempSpray -H226 is recommended
for smaller objects and indoor work.
Both hoses are qualified for the operation of an inside-fed
paint roller.
In the lacquer sector TempSpray -H326, -H226 and -H126 can
be used, but pay attention to the safety instructions, especially
in reference to explosion protection.
The TempSpray-H126 is specifically conceived for lacquer
work. Its minor hose-section raises the handling and reduces
the needed volume of lacquer to fill the hose.
The TempSpray-H126 is not capable for high-viscosity materi-
als and big nozzles.
TempSpray heated hoses must not be used in areas that come
under the Explosion Protection Ordinance.
2.2

COATING MATERIAL

Diluting lacquers and paints or those containing solvents, two-
component coating materials, dispersion and latex paints.
No other materials should be used for spraying without WAG-
NER's approval.
In particular, airless spray putty, high-viscosity coating
substances such as, e.g. roof coatings and corrosion protection
No other materials should be used for spraying without WAG-
NER's approval.
Pay attention to the Airless quality of the
coating materials to be processed.
Regard the directions from the colour-
manufacturer (technical data sheets of the
colours):
Some colours will be destroyed, if they are
heated over a certain level. Some colours at-
tain a high viscosity, thus they can damage
the heating wire in the hose.
The TempSpray-H326/H226 can be used for coating materials
with a viscosity up to 25,000 mPas.
The heating-hose TempSpray-H126 can be used for coating
materials with a viscosity up to 5,000 mPas.

COATING MATERIALS WITH SHARP-EDGED
ADDITIONAL MATERIALS
These particles have a strong wear and tear effect on valves
and tips, but also on the heating hose and spray gun. This im-
pairs the durability of these wearing parts considerably.

DESCRIPTION OF UNIT

3.1

GENERAL FUNCTION OF THE DEVICES

For a better understanding of the function see the technical
configuration below:
All 3 heating-hoses are heated via an electric conductor, which
is located directly in the colour-flow in the inside of the hose.
An electric current flows trough the heating conductor, which
is thereby heated up. Thereupon it changes its electrical resist-
ance proportional to its temperature. The electronic system in
the governor housing measures this resistance constantly and
calculates the temperature of the heating conductor out of it,
without any further sensor. The control electronics adapts the
current flow so that the set temperature is kept constant.
The output of the heating-hoses is limited. If the volume flow
rate is too high (nozzle too big) or the temperature of the ma-
terials before processing is too low, the results may vary. Of
course the surrounding air temperature has an effect on the
heating-ability of the heating-hoses, too.
Calculated values for the orientation can be found in the spec-
ification of each heating-hose.
