Amraiwadi, Ahmedabad, Gujarat

We offer corona generator with the latest IGBT based technology and working based on high frequency characteristics. High frequency operation permits electrodes to produce much higher density corona which results in better treating at lower power level and reducing power cost. safety features like over load current and zero speed switch provides to cut off power when incoming web breaks, and current exceeds the preset value indicating on panel light and sounds buzzer.

Corona treater is made in a totally enclosed  Configration providing safety in Opration. Treating  rollers are having good  quality Silicone Sleeves and rollers are dynamically balanced. Segmented electroade assembly provide easy working. Pnumetically operated  Split treater  box design provide easy straight threading of the web through the treater box. Air extraction blower removes the unwanted ozone gas from the teater box. The high voltage Transformer is placed near by the treater box to avoid long high voltage caring cable Connection.   Specification:- 1.Treatment width available from 1500mm to 3000mm. 2. treater roller diameter : 100-125-150mm 3. Easy threading arragement. 4. Line speed can be Matched as per Custamers requirement. 5. Trement side  can be single or  both sides. 6. Segmented electroed assambly or S.S. pipe arrangement. 7. Treater box can be operated Manually or pneumetically. 8. Ozone blower is Provided to romove Ozone gas.

We are engaged in offering a wide range of corona treatment system for blown film plant. Web size from Narrow (50 mm) to wide width (2500) are treated to the required Dynes density. Segmented electrodes provide easy and simple operation to selected treating width of films. The use of live roller system gives better efficiency and is covered with specially developed god quality silicone sleeves.

Multiple treatment systerm can be use whenever specially high treatment level is require. Treater units are placed  in series to enhance the treatment level of the film.

Narrow web corona treater are primarily used in converting applications like label printing / adhesive coatings substrates like teflon / fibre glass cloth  etc. Narrow web treater are generally single side treater with max. Width upto 12 inch and running at a line speed more than 100 mtrs. /min. In this type of narrow web treaters treatment rollers are of  6 inch dia covered with silicone rubber sleeves and two bare guide rollers. It has cantilever type of construction with segmented electrode ( 4 fins / 6 fins )  system covered with frp for operators safety. These treaters are comes with ozone extraction system and assembly open h. T. Interlock for operators safety. It has pneumatically operated electrode system for threading of the film.

Corona treaters for multilayer film plants are specially designed for higher output power capacity as per the client’s requirements. IGBT base corona generator ensure easy and reliable working at a higher frequency in the range of 20 k c/s to 40 k c/s. The heart of Corona genrator is high frequency invertor. Specially selected Components are used from the components suppliers like Semikron , Epcose (Siemens Germany) to ensure long life service. The body of panel is Powder coated to keep the unit dust free & stain free. The Display pannel is at a sutable lavel for Easy Working.   Specifications :-  1. High frequency working based on IGBT technology 2. Inpute voltage single or 3 phase as per requirement. 3. Capacity to deliver output power from 1.5 K.W. to 10.0 K.W. 4. Working frequency in the range of 35 kc/sec. 5. Internal sencers for Overload Trip. 6. "Zero speed Switch" to cut off power when incoming film breaks. 7. Trip alarm systerm.
