Overview
The Hotwatt SC62-3 cartridge heater is a standard industrial heating element designed for HVAC, refrigeration, and process heating applications. With a 220V supply and 180W output, this unit delivers consistent, localized heat in a compact form factor. The heater is designed as a slide fit into a standard reamed hole, with thermal expansion creating a snug fit for optimal heat conduction.
Key Features
- Voltage & Wattage: 220V, 180W
- Physical Dimensions: 5/8″ diameter × 3″ length
- Material: Stainless steel sheath for corrosion resistance
- Insulated Leads: 12″ fiberglass insulated leads (SF1)
- Low Watt Density Design: Reliable operation and extended element life
- Temperature Capability: Maximum surface temperatures to 1,250°F
Technical Specifications
Cartridge heaters provide localized heat to restricted work areas requiring close thermal control, with dies, platens and a variety of processing equipment efficiently heated. The SC62-3 configuration meets industrial standards for heating element reliability and longevity.
