MI Strip Heaters Deliver Long Life and Better Performance Problem: 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. Solution: 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/in 2 (15.5 W/cm 2 ) and so easily allowed the manufacturer to raise the required watt density to 65 W/in 2 (10 W/cm 2 ). This improved heater performance and enabled the manufacturer to maintain higher temperatures under varying loads.
