What
does Ameritherm do?
We manufacture solid state RF power supplies for precision
induction heating applications. MORE
ABOUT AMERITHERM
You
can use our power supplies for brazing, annealing, heat
treating, bonding, curing, catheter tipping - virtually any
process that requires selective heating of conductive
materials.
What
is induction heating?
It's
a great alternative to furnaces, ovens and torch heating;
induction produces fast, clean, non-contact and controllable
heat INSIDE the part. That's right - you heat from the
inside out! MORE
ABOUT INDUCTION HEATING
What
are you demonstrating?
We
are demonstrating fast, controllable precision heating using
our new Nova Star technology. Our new induction heating
power supplies feature automatic digital tuning for process
repeatability, a convenient remote heat station, full
display and control capability and a broad operating
frequency range suitable for many different parts and
applications.
For
our demonstration, we're using a 3 kW RF power supply, set
at 286 kHz, to heat stainless steel tubes (on a turntable)
up to 1,750°F in approximately 4 seconds. Then we maintain
this temperature for approximately 6 seconds to complete a
10-second heat cycle. You can view a series of still
photographs of the demo by clicking on the graph at left.
Okay,
where's your power supply?
It's
located behind the backdrop of our booth and connected with
about 30 ft. of cable. Our remote
heat stations bring precision heating directly to your
workbench or assembly line. Depending on your application,
the heat station can be located up to 200 ft. away from the
power supply.
How
much deliverable power can you supply?
As
low as 30 W, as high as 120 kW. We make compact
table models, bench models and floor models.
Excuse
me, where are the restrooms?
Two
rows down, right next to the $4 hot dogs.
Will
this work with my process and parts?
The
best way to find out is to send samples to our Applications
Laboratory for a free evaluation &
system recommendation. Our engineers will review your
parts & process requirements, and give you their best
advice up front. How can you lose?
How
do you know you're getting the right amount of heat?
For
precise temperature control in our demonstration, we use a
closed loop temperature control system with an Ircon Optical
Pyrometer. A fiber-optic sensor sends a signal to a
controller mounted in the base of the display. This is a
two-color device to allow for changes in emissivity of the
part and for a partially obstructed field of view.
Why
is this running at such a high frequency?
The
higher operating frequency increases the coupling efficiency
of the magnetic field to the part, resulting in improved
energy transfer to the part, and higher process efficiency
with reduced heating time.This means you can efficiently
heat smaller parts & thin walled tubing. With shorter
heating times, you can increase your throughput. We have an
8-page tech note "Precision Induction Heating"
with more information on high frequency induction heating.
You can download it from our on-line
database.
Hey,
do you know where I can get some food?
Two
rows down, right next to the line for the bathrooms...
I
have an old 30 kW power supply. Do I need to replace it with
another 30 kW unit?
Not
necessarily. It depends on how much of the 30 kW is actually
used to heat the part. We often find that the efficiency our
solid state power supplies allows you to replace your old
unit with a more efficient yet lower power model. Our 3
kW Nova Star power supply can replace older units of 5
kW output or even higher, depending on the application, and
do the same job.
Would
you help me with installation and training?
Sure.
We often send out a field technician for two days to provide
technical direction and instruction in the operation and
maintenance of the equipment. The cost varies with the
product, and we increase the standard one year warranty to
two full years.
How
tough is it to set up on my assembly line?
For
easy integration into automated manufacturing systems, our
Nova Star power supplies can be connected to a Programmable
Logic Controller using an isolated 24-volt I/O. The RS-485
interface provides full serial I/O control and status
reporting.
My
feet are killing me. Do you mind if I sit down?
Not
at all, but you have to read all of our sales literature
before you stand up again...
Why
should I work with you & not with another company?
We
specialize in individual induction heating solutions. We
won't send you an oversized power supply and hope that it
works by brute force. We've done thousands of applications
in our lab, and we have the expertise to find the best
induction heating solution for your application. MORE ABOUT AMERITHERM
Okay,
this might work for my process. Now what?
Call
us at 1-800-456-HEAT (toll-free USA) or (716) 889-9000. Or send
us an e-mail, and tell us more about what you want to do
with induction heating. We also invite you to send us some
sample parts for a free evaluation and system
recommendation. Visit the Applications
Lab section of our website for details.
