Product description
Miotti Heater SCSS027.0500.SB500 is an anti-condensation heater designed to protect the inside of electrical machines against moisture and condensation. It is recommended for motors, generators and alternators operating in demanding conditions (e.g., offshore, marine environments, cranes, well pumps, tropical climate). This version is 500 mm long, rated for 220 V AC and delivers 27 W.
Advantages and unique features
- Low-cost and effective protection against condensation inside electrical equipment.
- Built with 5 separate heating filaments for stable operation and even heating.
- Protective silicone rubber layer and a fiberglass sleeve.
- Suitable for class F and H applications and for machines exposed to vibration or shock.
- Wide operating temperature range: -60°C to +200°C.
Properties and applications
- Application: helps protect windings and internal parts of electrical machines against moisture and condensation in humid environments.
- Installation: applied around the base of the winding heads before impregnation.
- Installation rule: 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.
