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)
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 is then covered with one
or two walls of braided fiberglass yarn. We currently produce rope
heaters with resistance values from .45 Ohm/Ft up to 6000 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 standards if required.
Moisture Resistant Flexible
Heating Elements
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. (see Flexible Heating

Foil Laminated Heating Elements (Foil Heater)
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.
