In every case the atomisers are connected by means of a special High Voltage cable to a HV generator.
Electrostatic oilers – Technical specification
Positioning System – Spray header can move on and off line via a variety of retraction mechanisms. An Operator Panel displaying status of functions and alarms is supplied as standard. Terronics electrostatic oilers provide a better way to oil steel strip for rust protection, lubrication, or stamping.
Also offers roll coating equipment and coil process line maintenance services. When single coil instead of continuos strip are to be oiled the enclosure is equipped with a suitable threading table wich makes possible the passage of the strip head through the cabin and then it is automatically retracted or folder down.
In any case oil flows from the atomiser in form of cuspid wich under the effect of the electrostatic pressure break in tiny droplets forming a curtain of very fine oil mist. The system is ideal for application of very low coating weights of DOS or similar products normally required on Tin-plate, Black-plate and Aluminium lines. Additionally to our portfolio for complete strip processing lines and revamping of existing oilsr, we provide various auxiliary equipment to be used in cold rolling mills and metal strip production and processing plants.
In order to provide you the best suitable solution and discuss special requirements, please get in touch with us.
The easiest way to prevent corrosion is to treat the surface of the thin sheet with special anti-corrosion oils. The blade edge is formed electrosstatic a single plane, externally wetted electrostaticc a row of holes uniformly spaced along the blades body.
The atomising edge of the underside blade is twice the length of the topsite blade to ensure electrostwtic highest possible atomising density and transfer efficiency and is designed specifically to overcome the “flooding” common with conventional slot blades.
We are sure to provide a sound and comprehensive advisory service during a first technical meeting. Oil application is possible from both top-down and bottom-up orientation. We supply a standard two generators, one for each blade to take advantage of the much profitable opposite polarities systeme: Obviously, we also design and build electrostatic oilers for later deep-drawing applications for instance can-stock material or to apply hot melts especially for automotive materials.
Control and instrumentation can be located on coater assembly or remotely. Suitable for use in pickle line, galvanizing line, temper mill, slitting, inspection, and electrosyatic line applications.

The orifice dia is about 10 times wider than the conventional slot blade which is virtually self cleaning and mantenance free. Installation – Units are freestanding, ready for operation after connecting utilities.
Sheets and strips might already corrode shortly after production or processing, i. Flow control or monitoring can be provided optionally but is not considered to be essential to the performance of the machines and set a new standard of automation in this class of machines.
Maintenance – Maintenance requirements are generally minimal, stemming from the system’s elegant, low-energy design and extensive industry testing and operation.
Threading tables are normally driven by air cilynders. Typical Line Speeds – Up to fpm in existing installations, higher speeds are possible.
Special insulating fenders or plates protect the blades against accidental strip impacts. Allows Flexible Processing – A wide range of strip widths can be processed on one machine. System subassemblies include multiple 3 in.

The enormous advantage of the electrostatic principle is its more homogenous, constant and reproducible spreading of well measured oil quantities at variable strip widths and speeds, not at least thanks to a specially developed spraying bar. IThe yield of the oil is therefore eelctrostatic to the theoretical value and there no pollution or effluents treatment problems.
The side walls of the cabin are lined with highly insulating plastic plates wich act as electrostatic refectors. Anticorrosive coating for sheets and strips Electrostatic Oilers Additionally to our portfolio for complete strip processing lines and revamping of existing lines, we provide various auxiliary equipment to be elrctrostatic in cold rolling mills and metal strip production and processing plants. Spray Header Assembly – Consists of multiple 3″ or 6″ nozzles, number is determined by maximum width strip to be processed.
As a first in this field the bells revolutions are electronically controlled. Moreover the oil deposited by elecrtostatic means is free flowing from the sites of coils severely contaminating storage floors. Moreover because of a much lower capacity of the system the energy stored and released in case of a spark is much lower. The oil to be applied enters the A cavity of the blade and overflows from a range of small holes 6 drilled flow throught the blade wall reaching the shatp edge 3 Fig.
ISO Not Specified. With the most modern electronic generators the same results are obtained employing ma 0. Spraying systems electrosttatic always associated with a more or less pronounced overspray which impairs the deposition rate, polluting in the same time the working site. In both cases oil consumption is electfostatic over the theoretical – often even three or four times as much and the uniformity of the coating obtained is very poor.
The provided block and alarm circuits render the use of these generators extremely safe.
