York S1-025-47843-000 Heater

The York S1-025-47843-000 is an industrial-grade crankcase band heater designed for high-voltage HVACR applications. Operating at 480V and delivering 90W, this 8.5" diameter band heater utilizes a ceramic core (CC) design to ensure stable and uniform thermal distribution around the compressor housing. This specific HVAC replacement part is essential for preventing refrigerant migration and liquid slugging during the off-cycle, especially in low-ambient conditions. By maintaining the oil at an optimal temperature, the York S1-025-47843-000 heater protects internal bearings and critical compressor components from premature wear. Field technicians prefer this OEM York heating element for its precise fitment and rugged construction, making it a reliable choice for commercial packaged units and heat pumps. Its high-temperature stability and 480-volt compatibility make it a standard specification for heavy-duty industrial refrigeration and climate control systems.

• Prevents Refrigerant Migration: Maintains crankcase oil temperature to stop refrigerant from condensing in the oil during shutdown.
• Enhanced Thermal Efficiency: Features 90 watts of power and a ceramic core for consistent, uniform heat transfer.
• Industrial Specifications: Optimized for 480V systems, providing the necessary thermal output for large-scale HVACR equipment.
• Precise Fitment: The 8.5-inch diameter band is engineered to wrap securely around cylindrical compressor shells for maximum contact.

What is the primary function of the York S1-025-47843-000 in a 480V system?
This crankcase band heater is designed to keep compressor lubricant warm, ensuring that refrigerant does not mix with the oil, which could lead to lubrication failure upon startup.

How does a ceramic core (CC) heater improve HVAC performance?
The ceramic core provides superior high-temperature stability and more even heat distribution compared to standard wire-wrap heaters, preventing "hot spots" on the compressor shell.

Is this band heater compatible with other diameters?
The S1-025-47843-000 is specifically sized for an 8.5" diameter. To ensure proper heat transfer and safety, it should only be used on compressors with a matching shell circumference.
