Mica
insulated heaters are constructed of nickel-chrome resistance
wire wound uniformly around the mica winding card and insulated
by select quality mica either natural Muscovite or Heat Resistant
Paper Micanite, for a maximum operating temperature of 550 °C.
The main function of mica for the above applications is to support
and separate heating elements and nickel-chrome resistance wire.
To ensure trouble free operations, the resistance ribbon joints
and terminals are either spot welded or riveted as and where
required. Nickel plated eyelets are used as & where needed.
Mica
insulated heaters offer a cost-effective approach for all types
of heating applications because the mica construction provides
for an extremely rugged heater with thermal efficiency of over
87%.
The
low mass of the mica-insulated heater allows rapid heat-up and
cool down thus respond rapidly to control and operate at high
efficiency. The heat generated by the element in a mica-insulated
heater is spread over a larger surface area which by lowering
element temperature therefore gives longer lifetime of element.
Micatech Corporation
designs and manufactures custom mica insulated heaters with
greater design flexibility. Requirements for size, wattage and
voltage specifications can be precisely met with a custom designed
heater. Micatech Corporation has a proven track record of excellent customer
service and on-time delivery. |
