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 *Dowtherm is a trademark of Dow Chemical 8 eAFK – Oerlikon Barmag 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.
Heater Type Secondary set heater Dowtherm* Heater length Titer range den Preferred operational range Dowtherm set heaters with tubes generate evenlyset yarns and can be adapted in process by means of exchangeable tube inserts available in various designs – spiral pinched, half spiral pinched or fl at. Depending on process and product, the Oerlikon Barmag-developed solution allows yarn optimization in terms of loop-free yarns, a particularly important feature for multi- and microfi lament yarns. As standard, the heater is 1.30 m in height and available in standard and low-temperature versions for set treatment of highly-critical yarns. Secondary heaters are used for differential production on either side of the machine.
