Stenter Frame

Stenter Frame ensures proper transportation & heat treatment of fabric

Newly developed Fan house and Patented Uniflo Nozzle provides up to 15% higher drying efficiency with same power consumption compared to earlier design
2 numbers circulation fans per chamber will be provided; one for air flow from top nozzle and one for air flow from bottom nozzle
Common AC Inverter Drive (VFD) will be provided between 2 upper or 2 lower circulation fan motors
As a standard circulation fan motors up to 1500 rpm will be provided; as an option circulation fan motors up to 1750 rpm is available
Nozzles are drawable hence can be pulled out easily from doors for cleaning
Pneumatic Bypass System can be provided as an option; this system will help in reducing nozzle marks and yellowing of fabric during small machine stoppages

Separate drive for Left and Right Chain; duly synchronised by encoder system
Horizontally reversed chain with side lubrication facility with metaloplast / engineered plastic bush; duly greased with long-life grease
Re-greasing is required only after 6000-8000 working hours (depends on average working temperature and speed)
Steel Fabricated Track with Graphite Rail will be provided
Special Shock Absorbers are provided for smooth turning of chain
Less Friction as graphite is self-lubricating material
Fabric Protection Pipe can be provided to ensure higher overfeeding of fabric
Top side graphite rail enables chain to stretch the fabric up to desired level
Sturdy Track & Chain Design ensures high speed (up to 150 MPM) and higher stretch ability
