Heating solutions
First heater
Dowtherm*
Dowtherm contact heaters have been successfully used in
Oerlikon Barmag machines for over 30 years now and are –
even today – state-of-the-art technology, particularly for
multi and microfi laments. Anti-wear nitrated surfaces, deep
V profi le and special pinches for preventing yarn heat-outs
result in high yarn cleanness, extremely even crimping and
excellent dye uptake for the textured yarn.
Oerlikon Barmag Dowtherm heaters are open close
heaters for easier operation and maintenance, equipped
with manually closing doors. They are available in various
lengths suitable for processing different ranges of products.
Depending on the product portfolio customers can optimize
their production with the right selection and combination
of heater and cooling component. The correct selection of
these components can infl uence
– production speed and capacity
– energy consumption
– yarn quality

HTI
The HTI high-temperature heater makes it possible to
achieve high speeds coupled with excellent yarn qualities
due to stable yarn path and uniform heat transfer. The 1 m
long heater consists of two heating zones that, equipped
with special exchangeable inserts – developed and patented
by Oerlikon Barmag – enable fast and simple replacement
during standard maintenance work.
This increases overall machine effi ciency by minimizing idle
machine time resulting from maintenance and cleaning. The
inserts are cleaned outside the machine, hence eliminating
the customary problems associated with heater cleaning.
Inserts are available for both heating zones, either with
pinches or as full contact inserts. Different inserts can be
combined for optimization of the process, catering to the
special needs of highly critical products.
Due to its design, the Oerlikon Barmag HTI heater has
signifi cantly lower energy consumption in comparison to
its Dowtherm cousin. This - combined with signifi cant
potential process speed increase – makes the HTI heater is
a worthwhile alternative investment consideration.
