Product description
MIOTTI Heater SCSS07.1473.LB500 is an anti-condensation heater designed to help protect electrical machines against moisture and condensation inside the enclosure. The manufacturer recommends it for motors, generators and alternators operating in high-humidity conditions (e.g., offshore, marine environments, cranes, well pumps, tropical climates). This version is 1473 mm long, rated for 220 V AC and delivers 70 W, in the “L” (long stator) version.
Advantages and unique features
- Helps reduce condensation and moisture risk inside electrical machines in humid environments.
- Built with 5 separate heating filaments for stable operation and even heating.
- Protective silicone rubber layer and a fiberglass sleeve for industrial applications.
- Suitable for class F and H applications and for machines exposed to vibration and shock.
- Wide operating temperature range: -60°C to +200°C.
Properties and applications
- Application: helps reduce condensation inside rotating electrical machines (e.g., motors, generators, alternators) in demanding environments.
- Installation: applied around the base of the winding heads before impregnation.
- Installation rules: cover at least three quarters of the circumference; if the heater is longer than the head circumference, do not overlap it—leave at least a 5 mm gap to prevent localized overheating.
- Voltage check: verify the heater’s nominal voltage matches the power supply voltage before installation.
