MI Strip Heaters Deliver Long Life and Better Performance


A wave soldering equipment manufacturer was constantly replacing failed mica strip heaters. The heaters were stressed to performance limits while trying to maintain a minimum 600°F (315°C) temperature under increasing production loads.


Watlow's MI strip heaters cut the manufacturer's costs attributed to frequent downtime. The high thermal conductivity of the MI strip heater's mineral insulation provides watt density capabilities to 100 W/in2 (15.5 W/cm2) and so easily allowed the manufacturer to raise the required watt density to 65 W/in2 (10 W/cm2). This improved heater performance and enabled the manufacturer to maintain higher temperatures under varying loads.
