Why the NSWR1200-1600 is built heavy-duty
The NSWR1200-1600 is a wide, heavy-duty jumbo jigger with double frequency conversion. Runda sizes it for large-roll dyeing of open-width and circular knitted fabric.
A touch screen and push buttons control acceleration, stopping and the automatic functions. A PLC drives pneumatic valves to hold bath temperature within 1 °C.
It sits in the dyeing section. Cloth comes from the greige store or a washing range, and goes on to a washing line or a stenter.

Selection points for the NSWR1200-1600
Roll weight. Heavy rolls load the bearings and drive. State your heaviest roll and ask for the frame and shaft rating.
Width. Choose the width for your widest greige and confirm bath width and door opening.
Temperature control. The 1 °C accuracy is a PLC target. Ask for the sensor position and heating method that support it.
Knit fabric. Circular knit run open-width needs light tension and a good spreading roller. Say the knit type.
Auxiliaries. Large rolls benefit from cloth discharge and liquor circulation. Add them at order stage.

NSWR1200-1600 Jumbo Jigger: frequently asked questions
How accurate is the temperature control?
Runda lists PLC control of pneumatic valves to keep temperature within 1 °C. Actual bath performance also depends on heating capacity and insulation.
Can it run circular knit?
Yes, after opening the tube to open width. Keep the tension low.
What is the difference from the NSWR680-1000?
Both are double-inverter jumbo jiggers. Runda lists the 1200-1600 as heavy-duty for large rolls; confirm roll size and widths with us.
