TechniSwitch TS Series

NJ & VJ Tank Switchers        

Saves money, reduces down time

Technifab’s TS Series tank switchers provide continuous liquid nitrogen supply by automatically switching from the empty dewar to a full dewar.  The TechniSwitch Tank Switchers are available in either a non-vacuum jacketed or vacuum jacketed version. The VJ unit offers low heat leak, minimal boil-off, no condensation, touchable casing and eliminates solenoid chatter. It is the most efficient and safe switcher in the industry.


  • Reduces operating expenses by minimizing employee’s involvement in tank changeover.
  • Saves money by reducing system downtime during dewar replacements.
  • Empty tank alert and dry contact for customer provided alarm.

Additional benefits of the VJ version:

  • Improves environmental safety by eliminating pipe dripping and reducing slip hazards.
  • Reduces workplace hazard because outer casing is touchable.
  • Uses less liquid nitrogen through quicker cool-down enabling faster deliver to end use points.


  • Allows a variety of different tanks and VGLs.
  • Easy operation using touch screen PLC controls with simple adjustment.



Anywhere liquid nitrogen is supplied by multiple dewars. Ideal in laboratories or medical settings where a large outside liquid nitrogen tank is not accessible or possible.
