The Rheem-Ruud AS-58386-91 is a commercial-grade 5KW sheath heater element designed for high-demand electric heating applications and HVAC systems. Engineered for precision performance, this 240V heating element features a robust copper sheath construction that maximizes thermal conductivity while providing superior resistance to mechanical stress. For technicians performing HVAC element replacement, this component offers a cold resistance range of 23.7 to 26.2 ohms, ensuring electrical stability and consistent heat transfer across the entire surface area. As an OEM Rheem replacement part, it eliminates compatibility issues in compatible air handlers and water heating units, maintaining the original equipment’s efficiency and safety parameters. This industrial heating element is specifically built to handle the rigorous duty cycles of professional environments, providing a reliable solution for restoring system capacity without the guesswork of universal alternatives. Ensure you verify the specific model and serial number to confirm fitment before installation.

Key Benefits:

• Optimized Heat Transfer: The copper sheath design ensures rapid thermal response and efficient heat distribution for consistent system performance.
• Precision Resistance: Cold resistance rated between 23.7 and 26.2 ohms allows for accurate continuity testing and electrical load matching.
• OEM Standards: Genuine Rheem-Ruud heater element ensures structural integrity and safety compliance for 240V/5KW configurations.
• Application Versatility: Suitable for a range of commercial electric water heaters and HVAC air handling units requiring high-wattage sheath elements.

Common Questions:

• What are the symptoms of a failing heater element? Technicians should check for no hot water, unusually long recovery times, or circuit breakers tripping. Use a multimeter to verify if the AS-58386-91 has infinite resistance (open circuit) or a short to ground.
• Can this element be used in 208V systems? While physically compatible, installing a 240V/5KW element into a 208V circuit will result in significantly reduced wattage output (approximately 3.75KW), affecting heating performance.
• Why is the sheath material important? The copper construction of this 5KW sheath heater is specifically chosen for its high thermal conductivity and ability to withstand the mineral buildup common in high-temperature applications.
