York 2TP04521846 Electric Heater

The York 2TP04521846 is a robust 18KW 460V electric heater assembly designed for seamless integration into commercial and industrial HVAC systems, including rooftop units (RTUs) and high-capacity air handlers. Engineered for high-demand thermal output, this field-installed electric heat kit ensures consistent temperature control in environments where standard heating is insufficient. Built by Johnson Controls, the 18-kilowatt heating element provides rapid heat transfer through heavy-duty resistive coils, optimized for 460V three-phase electrical configurations. This OEM replacement part is critical for maintaining system efficiency and internal climate stability. Its compact 12x12-inch footprint allows for precise fitment within the heater compartment, reducing bypass air and maximizing the thermal discharge across the duct system. For technicians performing retrofits or emergency repairs, the 2TP04521846 offers a reliable solution for supplemental heating needs in large-scale air distribution networks.

Key Benefits:

• Precise 18KW heating capacity optimized for 460V industrial three-phase power supplies.
• Genuine York OEM replacement part ensures exact dimensional fit and electrical compatibility with native control boards.
• Rugged construction features high-grade insulating porcelain and durable heating elements for high-cycle applications.
• Engineered for commercial HVAC equipment, including air handlers and multi-zone rooftop units.
• Integrated safety features prevent overheating conditions during low-airflow events.

Common Questions:

What air handlers are compatible with the York 2TP04521846?
This 18KW heater is designed for York flagship commercial air handlers and rooftop units that support 460V power. Always verify the cabinet size and minimum CFM requirements in the unit nameplate before installation to prevent high-limit tripping.

Does this heater kit include the necessary limit switches?
Yes, as a professional-grade assembly, it includes the factory-integrated thermal limits required to protect the heat exchanger and ductwork from excessive temperature rises.

Can I use this 460V heater on a 230V system?
No. Using a 460V resistive heater on a lower voltage will significantly reduce the KW output and may cause control circuit failure. Match the voltage exactly to the system's power supply.
