Series manual apparatuses
for powder paintinng type CESS®
The series Manual apparatuses for powder painting type CESS®,
offered by COATTECH Ltd, include 6 types of apparatuses in classical
and special carrying out. They all are delivered ready to work.
The classical and special versions differ principally in electropneumatical
module - CESS®-PPS or CESS®-ATEL.
The pneumatical module CESS®-PPS is filled with conventional
pneumatical elements – manometers, regulators etc. The powder
dosing is realized by pressure change, the high voltage is indicated
by light-diode scale and the voltage regulation to the spray
gun is potentiometric. The electropneumatical module CESS®-ATEL
is designed on new principle.
The built-in electronics allows accurate adjustement of optimum
powder flow and high voltage to the gun and the set parameters
can be controlled on digital display. Previously remembered
work regimes are automatically given, depending on choosen coating
program. These programs ensure optimum and reproducible painting
Optimum painting regimes of plane details, profiles, tubes,
complex details, already painted ones are realized by choosing
three different painting programs – “Painting plane details”,
“Painting profiles and details with grooves” and “Repainting”.
Besides mentionned programs, the system allows programming
of other ones, such as painting with metallic paints, enamels
The different diagnostic functions of module are indicated
by light-emitting diodes. When the apparatus is switched off
the settings are automatically remembered and can be called
at any time.
The main components of series Manual apparatuses are the
following: electropneumatical module CESS®-PPS or CESS®-ATEL,
manual spray gun type EPM-100S and ejector.
The apparatus type “V”
(CESS®-PPS/V and CESS®-ATEL/V) is designed for
powder use directly from the powder packing and for quick and
easy colour change.
The apparatus type “T”
(CESS®-PPS/T and CESS®-ATEL/T) is designed for treatment of
big powder quantity, when big powder flow is required or at
work with two component paints. The apparatus contains reservoir,
having fluidization option.
The apparatus type “6L”(CESS®-PPS/6L and CESS®-ATEL/6L) contains fluidizing
6 l reservoir. It is exceptionnally suitable and effective for
small series details and quick colour change.
Series manual and automatic
coating sets type CEN®
The electrostatic coating sets, developed and produced by COATTECH
Ltd are basic equipment of installations and technical lines, offered
by the firm.
The wide variety of metallic details and products and the wide
range of requirements, such as productivity, kind of paint etc,
have provoked the creation of different equipment types. Regardless
of variety of types, series CEN® of coating sets include the following
regenerating unit with automatic blowing through system;
air purifying booth with built-in explosion protected ventilator
and high efficient air filters;
powder supplying system;
coating system including electrostatic gun, electrostatic
modules, ejectors etc;
type CEN®-17/U3 is remarkable with its closed booth.
The details that will be coated are put in the aperture for coating.
It is suitable for small production series of details of maximum
size 1 000 mm..
The sets type CEN®-08/U4,
CEN®-08R/U4, CEN®-12/U4 and CEN®-21/U3 are universal
coating equipment. They include universal changeable regenerating
unit with 4 filter elements, as well as universal powder feeding
apparatus. They find application in the production of wide range
of products, such as tube furniture, boilers, electrical switchboards,
refrigerators, illuminants, shelfs etc. They can be built into conveyor.
Set type CEN®-08/U5
has additional opposite operation post, served by second gun. It
is suitable for painting of details of big length (up to 6-8 m),
such as tube articles, metallic doors, parapets etc
Set type CEN®-19/U6
is passage with two operation posts, one-sided situated. It is suitable
to build into technological installation with big productivity.
Set type CEN®- 18/U6
is passage with two opposite posts. It includes two regenerating
units with 3 or 4 filter elements, two powder feeding apparatuses
and two electrostatic coating systems. It is designed for building
into mechanized technological lines, requiring two-sided coating
of long detaiils, such as aluminium and steel profiles, metallic
sheets, doors, woodwork etc.
Set type CEN®-20/U8
is designed for automatic painting in technological lines with continuously
moving conveyor. It includes automatic regenerating system with
two units, equipped with 4 filter elements, system for continuous
sieving of polymer powder. It has 2 manipulators and 4 automatic
guns. The set control is realized by central control unit that can
be equipped with system for identification of products by size.
An operation post with manual gun is foreseen in case of coating
correction. It finds application in technological lines for batch
production of articles, such as radiators, boilers, refrigerators
Devices for powder
The Electrostatic powder coating machine APEN® - 30 G 1(2) is
one of the latest COATTECH
machines, designed as a result of a consequent further development
of the preceding models APEN®, CESS® and especially of the model
APEN® - 150/2.
This new machine can be used for powdering of cables, wires,
hoses, profiles and bands with powders like talc, stearate, superabsorbent
powders (SAP) and so on. APEN® - 30 G 1(2) provides precise coating,
in order to meet the needs for high speed and quality. It has some
new systems, concerning fluidization, process of purifying filters,
microdosing and spraying. This give us an opportunity to decrease
dimensions, air consumption to 3-4 times and capacity about 2 times,
keeping the quality and output.
