“MAXPAK” Straight, Formed And Coiled Cable Heaters........optimum
"MAXPAK" high performance cable heaters are offered in a
variety of round, square and rectangular cross sectional
constructions. Standard configurations include precision coiled
or formed configurations as well as straight styles intended for
customer forming. Straight “MAXPAK” cable heaters are fully
annealed and are designed to satisfy customer in-house forming
and coiling requirements as well as providing a range of stock
elements for expedited delivery. Formed “MAXPAK” cable
heaters are factory formed to customer specifications. Precision
coiled “MAXPAK” cable configurations are available in both
configurations and custom coiled to customer specifications.
"MAXPAK" cable heaters feature precision wound parallel coil
elements fusion welded to nickel cold pins. The element
assemblies are embedded within high purity ceramic and
encased in an oxidation resistant metal sheath. The cable
heaters are swaged to the final rectangular, square or round
cross-sectional dimensions to compact the internal ceramic core
and ceramic insulation to near theoretical density. This high
density construction maximizes heat transfer and dielectric
properties and provides the high level of reliability and
performance required for even the most demanding of
High performance coiled coiled cable configurations are
engineered for cylindrical heating applications requiring any
combination of high temperature, maximum wattage and abuse
resistance. The coiled heaters inner and outer diameters provide
a large surface area and precision fit to external or internal
cylindrical surfaces. The resulting high rate of heat transfer to
the component maximizes element life and efficiency. Metal
sheathed construction combined with rugged lead terminations
provide superior durability. Common plastic processing
applications include heated bushings and nozzles for runnerless
tooling, sprue bushings and molding machine nozzles.
Coiled cable configurations are precision formed utilizing
computerized numerically controlled coiling machines for
optimum uniformity and precision. For even greater precision
and performance, the coiled cables can be sized to closer
tolerances by means of a secondary compaction process. This
process permits inside diameter tolerances to be held to within
plus or minus .0005 inches and outside diameter tolerances to
within plus or minus .001 inches.
Special cable heater design features including cold sections,
distributed wattage and internal temperature sensors can be
implimented when required. “MAXPAK” cable heaters can also
be equipped with a variety of special mounting fittings. Common
mounting features include tabs, flanges, NPT screw plug,
bulkhead and compression fittings. Lead terminations options
include the standard round cold extension with transition and
leads with a full selection of sleeve, wire braid and armor lead
protection. A variety of custom lead terminations are also
available for applications with special termination requirements.
- High Performance Swaged Construction. Compacted high
performance swaged cable heater design maximizes heat
transfer for optimum heater performance and element life.
- Premium Electrical Properties. High purity ceramic insulation
materials in combination with proprietary post processing
operations maximizes insulation resistance and dielectric
properties. All Duratherm cable heaters feature improved high
voltage stability and reduced ground current leakage values.
- Superior Internal Element Coverage. Cable element coil is designed
for maximum element wire size and surface coverage to increase
wattage capabilities and reduce wire loading.
- High Quality Micro Welded Internal Connections. Cable
element to conductor pin connection are fusion welded for
maximum connection reliability.
- Durable Heavy Duty Sheath. “MAXPAK” cable heaters feature
a rugged, oxidation resistant sheath. Available sheath materials
include various stainless steel and incoloy compositions.
- Versatile Configurations And Cross Sections. “MAXPAK”
cable heaters are supplied in straight, formed and coiled
configurations. Standard styles include round, square and
rectangular cross sections.
- Precision Coiled Styles. “MAXPAK” coiled cable heaters
are formed on computer controlled coiling equipment for for
optimum precision and repeatability in both single zone space
wound and multiple zone distributed wattage configurations.
- Transition Style Lead Terminations. Standard leads exit from a durable
transition providing a reinforced and sealed lead system. Optional
lead insulation materials and lead protection provide trouble free
- Fast Delivery Of Standards And
design system and a streamlined production process assures
fast delivery of both standard and custom cable heaters in
straight, formed and coiled configurations.
