STENTERS CONTROL
DWELL TIME CONTROL
AREL dwell time control guarantees that the processed fabric reaches the requested setting temperature and stays at
that temperature for the requested time.
Top class infrared temperature sensors are mounted in the stenter roof according to the length, the width and the number
of relevant chambers in the stenter. The sensors transmit the exact temperature of the fabric measured points to the
AREL PC based controller.
According to the information from the various sensing points and the stenter speed, the controller increases or decreases
the fabric speed ,so the desired dwell time is attained .The controller continuously logs the stenter speed and
temperatures for reporting and data analysis.
• As AREL’s non contact infrared temperature sensor can withstand the heat setting
temperature of the stenter chambers ,they are normally installed at minimal
distance above the moving fabric.
• Advantages:
1) improved temperature measurement due to minimizing the interferences
between the sensor and the target, fabric to be measured; and
2) prevention of dirt settling on the sensor because the temperature of the sensor
case is similar to the chamber temperature .
• For immediate installation and for easy access for service ,Arel provides the sensors
with complete adjustable stainless steel housing.
• Each sensor operates individually and there is no need for a concentrator . Each
sensor includes temperature display and setting switches .
• The number of sensors per installation is practically unlimited.
• The accuracy of the measurement is better than 1% of the measuring range.
• AREL provides solutions for heat setting of dry fabric ,for heat setting of wet fabric
and for drying only, eliminating the need for residual moisture sensors.
• For energy saving, the AREL controller can optionally reduce the fan speed at the
setting zone, as the energy requirement for heat setting only is relatively small by
comparison to the energy that is needed to increase the temperature of the fabric
before fabric setting begins.
TOTAL CONTROL
In addition to heat setting control, AREL also offers
TOTAL INTEGRATED CONTROL of all the stenter
functions.
Based on recipe management of the required set points
for each quality ,the AREL controllers can monitor and
control:
• chamber temperatures
• moisture retention
• stretch/shrinkage (over feed)
• fabric width
• fabric weight
• padder pressure
• exhaust humidity etc
AREL also offers complete standard as well as
customized reports per batch and summarizing reports
including: speed ,consumption, deviations from
standard and efficiency reports.
DISPENSING
AREL’s technology enables the operation of a common
chemical dispenser to the stenter foulard/padder from each
stenter controller.
The saving of a dedicated dispenser computer simplifies and
substantially reduces the cost of the system. This concept
enables an integrated recipe, including all the operational
parameters of the stenter, together with the recipe for all the
chemicals.
In order to reduce the waste of residual chemicals at the end of
each batch, the chemicals are dispensed in small amounts to
balance the actual pick up against the remaining fabric length to
process.
FINISHING MACHINERY
AREL’s unique software tools, PC based controllers and I/O
modules enable easy configuration of finishing machinery
to any control or monitoring function including:
• Recipe library management
• Process visualization
• I/O allocation and calibration procedures
• Report generators for historical events, trends,
chemicals and energy consumption, and much more.
BACK OFFICE
All AREL controllers can operate individually, or as
part of AREL’s MES- Management Execution System
for the wet processing production floor. In addition to
AREL’s production floor management system, AREL
also offers AREL APM- Process Management Systemfrom YARN TO DISTRIBUTION. AREL APM- Process
Management System covers all plant processes
together with sophisticated applications for Planning
& Scheduling and Global Sourcing.
