HEATING
ELEMENTS THAT EXCEED YOUR STANDARDS
In addition to being custom designed
to your requirements, all heating elements are fabricated
in accordance with the requirements of UL, CUL, and CSA.) 
Fiberglass Insulated
Flexible Heating Elements (Rope Heater)
 |
Fiberglass
Rope Heaters "Rope"
heating elements are ideal for counter-top appliances
such as coffee brewers, slow cooker, buffet warmers
and many industrial and commercial applications where
long life, low cost flexible heating is required. |
Flexible
fiberglass heating elements (often referred to as "Rope"
heaters because of their flexibility and appearance) are fabricated
by helically wrapping resistance wire around a core material.
This cordage can then be covered with one or two walls of braided
fiberglass yarn as the insulation. We currently produce rope heaters with resistance
values from 0.05 Ohm/Ft up to 11,000 Ohm/Ft. Multiple alloys, gauges
and stranding combinations are available. All fiberglass rope
heaters are built per UL-499 standard (Electric Heating Appliances)
and are recognized per UL file# E218455. Different thicknesses
of the insulating sleeving are available to meet different dielectric standards if required.

length, watt density, insulation color, termination

requirements. |

If
you require moisture resistance in low wattage flexible heaters,
Jen-Ter PVC or silicone insulated heaters can provide the
solutions. The core of these heaters resembles our high-temperature
elements, but PVC or silicone insulation offers both moisture
and heat resistance. The temperature rating of the moisture
resistant heaters is much lower than the fiberglass counterpart.

Foil
heaters can be used with any temperature ranges below 650°F
(343°C), foil laminated flexible heating elements can eliminate
expensive and complicated bracket mounting while providing a reliable
heat source. Foil heater elements can be constructed as strip
or blanket heaters. Foil laminated heaters typically contain a
flexible fiberglass heating element (see description above) laminated
between two sheets of foil coated with a liner-backed silicone
(600°F or (316°C) max. operating temperature) or acrylic
(350°F/302°F (177°C/150°C) max. temperatures -
two types) adhesive. These adhesives are very aggressive and provides
a strong initial bond, as well as a good ultimate bond. The aluminum
foil helps produce more efficient heat transfer than heating elements
that do not make complete surface contact.

Open
Coil Heating Elements
Open
coil heating elements remain one of the most popular heating elements
in use today. Whether utilizing nickel/chrome or iron based alloys,
open coil heating elements provide controllable electric heat
in a variety of residential, commercial and industrial applications.
Jen-Ter
Wire & Element Inc., can produce these heaters on ceramic or
mica forms using AWG 12 to AWG 40 gauge wire. These elements typically
contain one or more resistance coils, a thermostat and a thermal
fuse. Some complete assemblies will contain voltage dropping coils
to provide a low voltage source for PM motors. Plus, Jen-Ter does
have the capability to repair faulty open coil assemblies.
