MIOTTI Anti-Condensation Heater SCSS07.1473.LB500, long stator, 1473 mm, 220 V AC, 70 W, 500 mm leads, for motors and generators

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.

Technical parameters

Storage recommendations

The provided materials do not specify detailed storage conditions. To maintain product quality, store the heater in its original packaging, in a dry place, away from moisture, heat sources and direct UV exposure. Avoid bending or mechanical damage to the lead wires and fiberglass sleeve.

FAQ
