Frequently Asked Questions
Are There Temperature Limits?
Yes. The UHI element in its mylar covering is limited to 80°C
(176°F). The element however can be covered in other
materials with higher temperature ratings. Contact our engineers
for details.
Are There Shape Limitations?
Yes, as a rule we avoid curves. Rectangles or shallow
trapezoids are the standard shape but if you have a problem
please talk to us. We frequently solve many application problems
using unique methods.
Is the Heat Even?
Yes. The carbon element provides 100% coverage unlike
wire or foil heaters which have unheated spaces between hot
strips of metal. Carbon elements provide full coverage and
even distribution over it's entire surface. Our superior heat
coverage often allows us to heat an area with less wattage.
What Temperature will the Element Run?
We make the element to your size, voltage and wattage needs.
The temperature it runs at is determined by the environment
you install the heater into.
Is the Element Safe?
Yes. We have both CSA and UL component approvals*. In addition,
many of our customers have attained product approval using
heating elements in Korea, Japan, Australia, New Zealand,
North America and most of Europe.
Is the Element Self-Limiting?
No. UHI elements are constant output heaters which consume
the same power regardless of temperature. Temperature limiting
must be done by devices such as thermostats or controllers.
Does it Matter if I Use AC or DC?
No. The element is similar to a resistor flattened
into a sheet.
Can I Bend the Element?
Yes. The heater will curve to follow contours but should not be
repeatedly flexed or folded on itself.
Can I Put Holes in the Element
Due to the parallel circuit nature of our heating element, cutouts and
holes can be integrated in to the heater design. Care must be used to
ensure that dielectric protection is maintained.
How Long Does the UHI Element Last?
Our heating element, properly applied, will last decades. UHI elements
do not contain metal and therefore, will not have metal fatigue failure,
the leading cause of foil heater failure.
How Do You Electrically Connect to the Heating Element?
We have over 40 different methods and/or parts that can be used to
connect power to the heating element such as soldering wires,
riveting terminals and crimping terminals.
Do You Have a Catalogue?
No. UHI designs custom heating elements to fit your application.
Over the past 30 years our engineers have developed over 4000
different shapes, sizes, voltages, and wattages.
