Wire-wound Rubber Heaters
Overview
These silicone rubber heaters have a wire-wound element and
are economical in large sizes.
• Mean time between failure (MTBF) of 100,000 hours+
provides longer heater life under continuous operation
• Rugged construction and high ductility allows repeated
flexing for easier installation
• Element wires sealed inside silicone rubber protects electrical
connections from moisture preventing costly downtime for
field repairs
• Uniform heating to 220°C (428°F)
• Heater lengths to 90" (1.8 m)
• Mount to flat or curved surfaces
• TÜV and UL component recognition marking are standard
• 2.5, 5, 10, 15 watts/in² (0.39, 0.78,1.55, 2.33 watts/cm²)
at 120 or 240 VAC
• Lower leakage current due to capacitive coupling
Typical applications
• Prevent condensation in motors and generators
• Protect instrument cabinets from cold and humidity
• De-icing
• Control fluid viscosity in valves and vessels
• Industrial ovens and thermal processing equipment
•Platens
• Medical devices
Custom options
• Custom shapes and sizes to 22" × 90" (560 × 2285 mm)
• Custom resistance to 200 Ω/in² (31 Ω/cm²)
• Integral thermostats
• RoHS compliance
• Contact Access: Minco Sales and Support for custom
design assistance
