Watlow Electric Mica Strip Heater Electric Heater User Manual


 
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

MICA STRIP HEATERS
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
Optional stainless steel sheath
Available for more corrosive atmosphere
Nickel-plated steel terminal posts
Posts are securely riveted to ensure a positive,trouble-free
connection to the resistance circuit
Computer-aided design engineering
Design combination of ribbon gauge, total wattage and
winding spacing maximizes heat transfer and life of the
heater
Excellent dielectric strength guaranteed
All incoming mica receives a quality control inspection
