Shingare Industries Make Electric Tube Expansion System is operated by Control Panel (Electric). This tube expansion system is used mostly for tube expansion of condenser tube expanders, heat exchanger tube expanders.

The control panel unit controls automatically after reaching the required Torque, Tube Expander retracts out from the tube after pressing the reverse Button. This automatic system ensure tube are rolled to maximum tightness without excessive stress of work in Tube metal hence preventing damage at Tube ends or distorting Ligaments of Tube sheet.

Current based electric tube expansion system is suitable for tube rolling of tube OD ¼” (6.4mm) to 4” (100.4mm).

Note : Highly Advanced – Micro processor based Torque Control Unit – is also avaibalbe – quote on request.



Electric Torque Controller / Wattage Based
Latest Micro-Controller Chip Installed for controlling the functions of Unit & single circuit board for easy maintenance.
The LED on Torque Controller helps to indicate the connection of drive automatically.
To produce indentical results it is accurately calibrated digital torgue setting with resolution of 1 watt which makes torque setting accurate.
For long life of the system soft start is provided for all drive reducing starting curren in the drive.
Four different torque setting suitable for four different drives.
To avoid absued or overused appropriate wattage range is automatically selected for connected drive.
On pressing button on LED actual drive wattage(torque),Set Wattage(torque), drive current & voltage line is displayed on LED.
The system is adjustable for Reverse time from(1sec – 100 sec), Trip time (0.1 – 10 sec), Pause time(interval time between cycles), Adjustable from(01 sec – 100 sec) In emergency case push buttom manual reverse push button can be used.
Two mode is been used Foot Switch & Hand (trigger) also speed of the drive is adjusted with help reverse rotation.
Two mode can be used for Expansion either in Single Mode or Auto repeat Mode.
The Drives are well protected over current by short circuits with help of MCB.
At the time of trouble shooting Plug in type PCB’s are used which reduce down time.
Forward, Reverse & Trip indication are provided on LED Indicators.
The system is designed with High Quality SCT Technology, which have better voltage, current & dv/dt ratings that triacs. This benefit to the power circuit & reliability it becomes failsafe.
Only one Instrument can be used for replacements of spares inside the panel such as PCB’s, Transformers, CT, and Relays DPM etc.
The system can be compatible with PC / Printer also.
