The Watlow EB metric cartridge heater is a proven performer like the industry-standard Watlow
FIREROD®. The same premium materials and tight manufacturing controls go into the
construction of the Watlow EB metric cartridge heater. The only difference is that the Watlow EB
metric cartridge heater is packaged in a more economical metric-sized design. Instead of having
the high watt density capabilities of the FIREROD®, the Watlow EB metric cartridge heater is
made for medium watt density applications while still providing the superior heat transfer, uniform
temperatures, and resistance to oxidation and corrosion for which Watlow heaters are known.
Watlow EB metric cartridge heaters are built using only the finest materials and construction methods,
and are backed with extensive quality assurance programs. Years of testing have proven certain
construction materials and manufacturing methods to yield the best performance for Watlow EB
metric cartridge heaters. Following are the standard materials used in Watlow EB metric cartridge
heaters:
- The Insulation:
-
Watlow uses only high purity MgO, compacted (swaged) to a carefully predetermined
and closely monitored density. This assures high dielectric strength and efficient, fast
heat transfer. Swaging has the added benefits of: permitting the resistance wire to
operate at lower temperatures, a critical factor in longer heater life; enabling users to
achieve process temperatures faster; providing more uniform heating to the application;
reducing energy costs through better heating efficiency; and, making the heater more
durable and more resistant to shock and vibration.
- The Resistance Wire:
-
Watlow's nickel-chromium wire of computer calculated gauge, length and spacing is
wound on a supporting core and precisely centered assures even, efficient distribution
of heat to the sheath.
- The Lead Wire:
-
Watlow uses only the finest high temperature wire available. Flexible stranded wires,
with silicone-fiberglass sleeve, insulate the wires to temperatures of 250°C
(480°F).
- The Pins:
-
Metallurgically-bonded conductor pins, crimp-connected to the resistance wires, ensure
trouble-free electrical continuity. This process provides lead flexibility just 8 mm (5/16
inch) from the end of the heater.
Due to Watlow's experience and tight manufacturing controls, the Watlow EB metric cartridge
heater provides an economical solution for medium watt density applications while still providing
the superior heat transfer, uniform temperatures and resistance to oxidation and corrosion for
which Watlow heaters are known.
