See chapter 4.1.1
The Evobell 3500 is a component of stationary equipment for electrostatic coating with
flammable liquid coating materials, in accordance with EN 50176.The spray system meets
the requirements of category 2G type B-L.
However, non-flammable liquid coating materials may also be processed with the Evobell
3500. In this case, the requirements of EN 50348 (Stationary equipment for electrostatic
coating with non-flammable liquid coating materials) must be complied with. Depending
on design, the spray system is categorized as type A-NL (discharge energy W < 350 mJ) or
type B-NL (W > 350 mJ).This categorization must be carried out before commissioning the
system, and marked accordingly on the system.

Danger zone:
The distance between the workpieces and the parts of the spray system under high volt-
age must be large enough to prevent a sparkover during normal operation. A minimum
distance of 200 mm; 8 inches is recommended in the area of the atomizer bell and a mini-
mum distance of 100 mm; 4 inches in the area of the cylindrical cover. If required by the
application or if demanded by the design, these distances can also be smaller. In this case
it is necessary to check that sparkovers do not occur.

2.5 SETTING UP STATIONARY ELECTROSTATIC SPRAYING EQUIPMENT
Safe handling of WAGNER spray units
Mechanical sparks can form if the unit comes into contact with metal.
In an explosive atmosphere:
Do not knock or push the unit against steel or rusty iron.
Use only tools that are made of a permitted material.
Ignition temperature of the coating material
Ensure that the ignition temperature of the coating material is above the maximum
surface temperature.
Medium supporting atomizing
To atomize the material, use only weakly oxidizing gases, e.g. air.
Surface spraying, electrostatic
Do not spray unit parts with electrostatic (e.g. electrostatic spray gun).
Cleaning
If there are deposits on the surfaces, the unit may form electrostatic charges. Flames or
sparks can form if there is a discharge.
Remove deposits from the surfaces to maintain conductivity.
Use only a damp cloth to clean the unit.
The high-rotation atomizer is a component of a stationary spray system. EN 50176 must be
observed when stationary spray systems are installed. One of the requirements is that
activation of the high voltage is only possible by using a key. De-activation of the high
voltage must also be possible without a key.

4.1 FIELDS OF APPLICATION, USING IN ACCORDANCE WITH THE INSTRUCTIONS
EVOBELL 3500 is an air-bearing high-rotation atomizer. The device is suitable for atom-
izing liquid materials, in particular coating materials, under the influence of electrostatic.
4 DESCRIPTION
This high-speed rotation atomizer can be used to process both flammable liquid coating
materials (solvent-based paints) and non-flammable liquid coating materials (water-based
paints).
When using flammable liquid coating materials
It is imperative that the high-rotation atomizer be equipped with the resistance block. In
this case the system is classified as Type B-L (W < 350 mJ) in accordance with EN 50176. A
danger thus exists through explosive energy, but no danger through electric shock.
Coating paints, primers, corrosion protection, structure paints, etc. with a specific resist-
ance > 50 k(to WAGNER/Ransburg scale) are suitable for processing. The electrostatic
effect has no effect at strongly conductive materials and at such materials with an exces-
sive electrical resistance, i.e. no „paint wrap-around“ is present on the spray object. The
suitability of the sprayed material with regard to the charging ability can be read from the
actual values for the high voltage (kV) and for the spray current (µA).
e.g.
➞High kV value, low µA value (no wrap-around) = Paint with excessive electrical
resistance.
➞Low kV-value, high µA-value (no wrap-around) = Excessive conductivity of the paint.
When using non-flammable liquid coating materials
If water paints are used, the entire system (high-rotation atomizer with paint supply) is
brought to high-voltage potential. The system corresponds to Type A-NL (W < 350 mJ) or
Type B-NL (W > 350 mJ), depending on the structure in accordance with EN 50348. If the
system is classified to Type B-NL, a danger exists through electric shock
The complete system must be safely earthed before being accessed by people.
In the event of application problems, contact your WAGNER branch or the paint manufac-
turer.
4.1.1 PROCESSABLE MATERIALS
A large portion of stationary electrostatic paint spray systems are currently being con-
verted to water-based paints. At the same time the fire and explosion protection of these
systems can be eased considerably, if the water-based paints used can demonstrably be
considered non-flammable.
4.1.2 CATEGORIZATION OF WORKING MATERIALS
17
Evobell 3500
OPERATING MANUAL
EDITION 05/2010 PART NO. DOC387841
Water-dilutable paints such as are in principle divided into 3 groups:
Green Non-flammable (non-combustible) paints
Yellow Paints with low flammability
Red Flammable paints
Non-flammable:
Paints in this group have the following composition:
Gew. % H2O > 1.70 x Gew. % LM + 0.96 x Gew. % ORG
Where:
Gew. % Weight percent
H2O Water
LM Liquid organic phase (solvent mainly consisting of higher ethylene glycol esters)
ORG Solid organic phase (solids mainly consisting of binding agents and pigments)
Such paints behave like water in respect of flammability in liquid form (liquid phase) and in sprayed form.
Cleaners and thinners must also be non-flammable. A possible cleaner and thinner is, e.g. water with less than
35 weight percent 1:1 butylene glycol/N-propanol.
Paints in this group are categorized as non-flammable liquid coating materials.
When using non-flammable spray materials, the requirements of EN 50348 (mainly protection against contact)
must be complied with.
Low flammability:
Paints in this group have the following composition:
Gew. % H2O > 1.50 x Gew. % LM + 0.49 x Gew. % ORG
Spray clouds of these paints cannot be ignited by sparks with an energy < 4 J. Explosion protection in the spray
area is not usually necessary if ignition sources with an energy of more than 2 J do not occur.
Paints in this group are categorized as difficult to ignite.
When using spray materials that are difficult to ignite, the requirements of EN 50176 must be complied with.
Flammable:
Paints that do not meet the criteria for non-flammable or difficult to ignite.
Paints in this group are categorized as flammable liquid coating materials.
When using flammable spray materials, the requirements of EN 50176 must be complied with.
Please contact your local WAGNER dealer and the paint manufacturer if you encounter application problems.
