We offer current based torque controlled tube expansion system and wattage based electronic torque controllers. These have solid state design with no moving parts thus no wear and tear of parts. The systems are designed for no noise emission and long life. Along with efficient product design, durability and competent functionality, price competency is a prime highlight of our Torque Rolling Control systems.

BHARTIYA Electric Tube Expansion Drive Unit is governed by a separate Electronic Control Panel which is adjusted by a simple Digital Display. When the Electrically Driven Motors reaches the desired Torque, the Control Unit Mechanism automatically shuts off the Power and on pressing the Reverse Button the Tube Expander retracts out from the Tube. The Fully Automatic system ensures the Tubes are rolled to maximum tightness without excessive cold worked stress in Tube Metal which prevents injuring Tube ends or distorting Tube Sheet Ligaments.

Note: Latest Design Highly Advanced - Micro processor based torque control unit - Also available - quote on request.

FEATURES:

• Fully Solid State Design - no moving parts - no wear and tear of parts - no noise - consequently long life.
• Uses the latest micro-controller chip for control functions.
• Uses one main circuit board for easy maintenance.
• Accurately calibrated digital torque settings with a resolution of 1 watt makes torque settings accurate and can be easily reproduced for identical results.
• Connected drive is automatically recognized & indicated by means of LED on the torque controller.
• Soft start has been provided for all drives, which reduces starting currents in the drive. As a result, life of carbon brushes & drive increases.
• Torque setting arranged in four different ranges to suit four different drives. Appropriate wattage range is automatically selected for the connected drive, hence drives can not be abused or overused.
• Actual drive wattage (torque) is displayed. Set wattage (torque), drive current and line voltage can be seen by press of a button.
• Adjustable reverse time from ( 1 sec to 100 secs.)
• Trip time adjustable from ( 0.1 sec to 10 secs. )
• Pause time (time interval between cycles) adjustable from ( 1 sec to 100 secs.)
• Manual reverse by push button, in case of emergency.
• Drive Speed adjustable in reverse rotation.
• Hand (trigger) mode or foot switch mode, both are available.
• Expansions can be carried out either in single cycle mode or auto repeat mode.
• MCB has been provided to protect the drives against over current by short circuits.
• Plug in type of PCBs reduce down time to minimum during trouble shooting.
• LED indicators provided for forward, reverse & trip conditions of drive.
• Superior SCR technology has been incorporated rather than triacs. SCRS have much better voltage, current & dv/dt ratings than triacs. This leads to greater reliability & the power circuit becomes almost failsafe.
• All the spares inside the panel viz : PCBs, Transformers, CT, Relays DPM etc. can be replaced by use of only a screw driver.
• PC/Printer compatible.
