In refrigerated shipping containers, efficient defrosting is critical to maintaining consistent cooling and preventing ice buildup on evaporator coils. The reefer units - defrost heater plays a pivotal role in this process, ensuring reliable operation even in subzero environments. Here’s an in-depth look at its specifications, functionality, and why quality matters.

• Sheath Material: 321 stainless steel offers superior corrosion resistance and durability in harsh maritime conditions.
• Power Rating: 750W ±5%/-10% at 230V ensures precise heat output for effective ice removal.
• Current Leakage: ≤0.850mA at 2305V minimizes electrical hazards and system stress.
• Insulation Resistance: 200MΩ safeguards against short circuits and voltage fluctuations.
• Cold Resistance: 72Ω ±10% at 20°C ensures stable performance during startup.
• Epoxy: SWCRM3705 provides thermal stability and moisture-proof protection.
• Temperature Range: Operates reliably from -40°C to 85°C, ideal for global reefer routes.

Why Defrost Heater Performance Matters

A malfunctioning defrost heater can lead to reduced airflow, increased energy consumption, and premature compressor failure. High-quality reefer units - defrost heaters comply with standards like UL 499 for safety and IEC 60335 for electrical integrity, ensuring long-term reliability. Proper insulation and corrosion-resistant materials also prevent costly breakdowns in saltwater or humid environments.

Choosing the Right Defrost Heater for Your Reefer

Operators should prioritize heaters with sealed sheaths to prevent refrigerant leaks and epoxy coatings that withstand repeated thermal cycles. For extreme climates, select models certified for -40°C startup and 85°C ambient temperatures. Always verify compatibility with your reefer’s voltage and control system.
