New Montex 7000 TT stenter designed
specifically for technical textiles finishing
The new Montex 7000 TT from A. Monforts Textilmaschinen introduces a completely
new concept of finishing specifically for coatings and the technical textiles
sector. Meeting all the requirements for finishing of technical textiles, the
Montex 7000 TT provides the highest product quality with absolute uniform
drying.
The new TT stenter features 4 m long chambers/ modules compared with the
standard 3m long units. For coating purposes, the extended chamber provides an
absolute even nozzle pressure.
A single gas burner or heating element and two ventilators per chamber therefore
make, for example, a coating line comprising three 4 m chambers more economic
than four 3 m chambers.
With the second and subsequent chambers installed in secondary centre type modes
absolutely homogeneous distribution of air flow is assured. Featuring left/right
symmetrical integrated exhaust air ducts, the Montex 7000 TT operates at a
nominal process temperature of up to 190°C. For special technical processes, an
optional version is also available for applications requiring temperatures of
300°C or above.
TwinAir-X
The Montex 7000 TT introduces the new TwinAir-X circulating air system with a
cross-type arranged nozzle system for an absolute homogeneous air and
temperature distribution for the upper and lower process-air, required for
coating processes.
The TwinAir-X system offers reduced production costs thanks to optimised energy
consumption. Each 4 m drying compartment features optional fan outputs of 7.5
kW, 11 kW or 18.5 kW using energy saving frequency controlled EFF1 type fans.
Developed specifically for technical textiles, the TwinAir-X nozzle system
provides double lock air flow into and across the fabric run. The nozzle supply
air ducts and the nozzles can also be cleaned without them being removed.
High efficiency, 150 mm insulation line the drying compartments.
All types of heating are suitable for the system including gas direct, gas
indirect (Exxotherm), thermal oil, steam, hot water and electric heating.
For the first time, Monforts proven elevating doors are fitted on both sides of
the stenter providing optimum access to the stentering chains, nozzles, gas
burners, heat exchangers and the fabric.
Flameless infra-red pre-dryer
The optional front end in-feed features an integrated gas-fired infra-red
flameless burner for pre-gelling foams.
The pre-dryer can be accurately adjusted to enhance performance. Improved
temperature distribution of fresh air intake in the first drying compartment is
assured. An automatic cut-off eliminates any fabric spoiling.
‘Golden’ stentering chains
The new stenter includes the latest Hercules ‘Golden’ stentering chain providing
more than 10,000 hours re-greasing intervals.
The system features fully encapsulated bearings which ensure that the roller
chain runs dry through the stenter. It requires minimum lubrication thanks to
Monforts patented direct lubrication injected into the bearing.
Heat recovery
Monforts Energy Tower 7000 ‘stand alone’ heat recovery system is also available
with the TT stenters. The ‘stand alone’ cabinets installed alongside the stenter
feature five integrated heat recovery modules. With the Monforts system
capitalising on the high temperatures of the exhaust air to heat the fresh air
entering the stenters savings of up to 30% in energy costs can be achieved.
The new stenter also offers CO² fire protection and an ATEX (ex-proof) certified
version for specialised coatings containing hazardous chemicals is available.
A ‘Condensate Protect’ option is also available with dry panels and a drain for
condensate removal on completion of coating treatment.
Qualitex control systems
Either of Monforts Qualitex control systems can be used with the new Montex 7000
TT. The Qualitex control systems can be used with the new Montex 7000 TT. The
Qualitex 540 features touch screen control for many of the most important
production parameters. It is also prepared for the Monforts online assistance
teleservicing with language changeover if required.
Qualitex 750 is a fully programmable logic process controller and is expandable
and adaptable for all tasks associated with in modern textile finishing.

New ‘Stand Alone’ heat
recovery option from Monforts A
new ‘stand alone’ heat recovery option for thermo-treatment
machines and Montex stenters from Monforts is eminently
suited for installations where space above the machine is
restricted by low ceilings.
A new modular ‘stand alone’ heat recovery
system Energy Tower 7000, is introduced as a compact working
option for thermo treatment machines and Montex stenters,
where space above the machine may be restricted by low
ceilings.
The Monforts Energy Tower 7000 can be
used for hot flues, relaxation dryers and continuous dyeing
ranges and also retrofitted to existing Montex stenter
installations. The new Energy Tower is suitable for Infra
Red dryers up to 250°C used in thermal, curing and dyeing
processes.
Fresh air, passed through the heat
recovery system is heated by the exhaust air before entering
the respective thermo-treatment unit. With the Monforts heat
recovery system, capitalising on the high temperature of the
exhaust air, savings of up to 30% in energy costs can be
achieved.
The Energy Tower, housed within a 1.30 m
X 1.70 m X 2.9 m high cabinet, features integrated
ventilation with noise protection.
Large access doors make the system easy
to service and maintain. The exchanger tubes within each
module, for example, can easily be cleaned at ground level
using just high pressure water. Any condensate can also be
easily be collected.
