Mica Thermofoil Heaters
High watt density and temperature range
Mica Thermofoil™ heaters consist of an etched foil element sandwiched between layers of mica. Installed by clamping to heat sinks, mica heaters provide the ultimate temperature and wattage capability for fast warmup.
Salient Features of Mica Thermofoil Heaters
• Broad temperature range of -150º to 600°C provides faster processing and cycle times for greater production output
• High watt density capability to 110 W/in² (17 W/cm²) provides faster processing times than conventional mica strip heaters
• Custom profiled heat density and mechanical clamping offers uniform heat sink temperature which can improve processing yields
• UL certification is available which can save time andmoney for end-use UL device recognition
• Can be factory formed to curves
• Heaters are suitable for vacuum use after initial burn-in
