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 results.

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 etc.

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.

Devices for powder electrostatic coating

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.
