ISER is an immersion gas burner which is ideally suited for a variety of galvanizing
applications. Immersion heating is in extensive use in the wire processing industry, and
is now being successfully applied by Thermix in processes where electric heating was the
only available option. Thermix Melters have many advantages, some of which include the use
of less expensive natural gas, easy maintenance, and no costly down time compared to when
inductors unexpectedly fail on electrically heated applications.
Thermix has been at the forefront of the development and implementation
of this exciting new technology, and has made the process of conversion of existing
equipment easy and cost effective. These objectives were achieved by working closely with
our clients engineers and consultants. Thermix offers a design and supervision
service, along with prepackaging of the gas controls and electrical systems that are an
integral part of every new Thermix Melter. In addition, Thermix offers complete
fabrication and installation packages. Thermix presently has melters in Primary Zinc
Producers, Continuous Pipe Galvanizing, Continuous Tube Galvanizing, Continuous Strip
Lines and Wire Lines. Reference list available upon request.
The Thermix Melter is a completely ceramic lined vessel that contains
the working volume of liquid zinc. Durable refractories, graded to ensure low heat losses,
operational integrity and long life, are used inside a fully welded steel shell. The
thermal gradient that exists between the zinc inside the Melter and the casing ensures
that zinc never comes into contact with steelwork. In practice the lining is self-healing,
giving a service life of upwards of 25 years, even under the most severe working
Thermix Melters are inexpensive to run and provide exceptional
temperature control, often within 5F. The ISER burner is a compact
heat source, pumping out the equivalent of 40KW of electric heat for each fitted burner.
Thermix Melters are similar in size to equivalent induction furnaces and are often
significantly smaller than traditional galvanizing kettles, or ceramic hood furnaces. This
leads to very short return on investment times (ROI), even for quite small installations.
Add the low operating cost to the advantage of no down time, no costly inductors or
kettles to hold in inventory, long service life, and accurate temperature control, and it
is clear that the new Thermix Melter is an obvious choice for galvanizing
