Product description
MIOTTI Heater SCSS03.0432.LB500 is an anti-condensation heater designed to protect the inside of electrical machines against moisture and condensation. It is used in electric motors, generators and alternators operating in high-humidity conditions (e.g., marine, offshore, tropical environments). This model is 432 mm long, rated for 220 V AC and delivers 30 W.
Advantages and unique features
- Effective prevention of condensation inside electrical equipment (helps protect windings and insulation).
- Construction based on 5 separate heating filaments, welded at the terminations.
- Protective silicone rubber layer plus a fiberglass sleeve (robust for operating conditions).
- Suitable for class F and H applications and for machines exposed to vibration or shock.
- Wide operating temperature range: from -60°C to +200°C.
Properties and applications
- Anti-condensation protection: for equipment running in humid environments (e.g., marine equipment, cranes, well pumps, tropical conditions).
- Winding 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—leave at least a 5 mm gap to prevent localized overheating.
- Voltage selection: verify the heater’s rated voltage matches the power supply voltage.
