Economical and
Reliable Source for
Industrial
Equipment
The Watlow mica strip heater is an economical and reliable
source of heat for industrial equipment. A mere 15 mils
(0.4 mm) thick mica insulator on both sides of the resistance
element provides complete electrical insulation and offers little
resistance to efficient heat flow. Plus mica withstands high voltage
spikes, resists moisture and is inert to most chemicals. UL®
component recognition is available for applications to 900˚F
(480˚C) sheath temperature, file number E52951.
Features and Benefits
Low mass construction
• Heats up fast to provide quick response to control input
Flat resistance ribbon
• Heat is generated over a broad area; this design solution
puts the heat source closer to the work
Rust-resistant, zinc-coated steel sheath
• Material gives the heater rigidity and improves emissivity
Performance Capabilities
• Sheath temperatures to 900˚F (480˚C) on zinc-coated units
• Sheath temperatures of 1200˚F (650˚C) on stainless steel units
• Watt densities to 55 W/in2 (8.5 W/cm2)
Optional stainless steel sheath
• Available for more corrosive atmosphere
• Maximum voltage 480VÅ(ac)
Nickel-plated steel terminal posts
• Posts are securely riveted to ensure a positive,trouble-free
connection to the resistance circuit
Applications
