Emerson Alco 058074 Power Element

For service technicians maintaining light-to-medium commercial refrigeration systems, the Emerson Alco 058074 Power Element is a critical replacement component for ensuring precise superheat control. Also identified by the industry part number X-26300MC-1, this unit is designed specifically for R134A refrigerant applications utilizing a medium temperature charge (MC). The X26300-MC-1 features a durable stainless steel construction to prevent corrosion and long-term fatigue, a common failure point in high-vibration condensing units. The integrated 5' capillary tube offers sufficient length for versatile mounting of the sensing bulb onto the suction line, facilitating accurate thermal response to change in evaporator load.

This Alco powerhead is essential for refurbishing or repairing thermal expansion valves (TXV), maintaining the energy efficiency and system durability required in professional HVACR environments. Its interchangeable power element design allows contractors to keep systems operational without needing a full valve body replacement, reducing downtime on the job site. When replacing an existing 058074, ensure the sensing bulb is properly insulated and secured for optimal performance.

• Universal Compatibility: Works as a direct replacement for the Emerson X26300-MC-1, ensuring seamless HVAC troubleshooting and repair.
• Corrosion Resistance: High-grade stainless steel construction protects against moisture-related failure in demanding environments.
• Optimized for R134A: Specifically calibrated for medium temperature applications, providing stable refrigerant flow control.
• Simplified Installation: Features a 5-foot capillary tube for flexible bulb positioning on diverse evaporator coils.

Common Questions:

Is the 058074 compatible with R-12 systems?
While historically similar, the X26300-MC-1 is specifically charged and optimized for R134A refrigerant. Consult manufacturer P-T charts if attempting to use this in retrofit scenarios.

Can I use this power element on any Alco valve body?
This element is designed for the HF and HFK series valves. Verify your existing valve body series to ensure the threading and pin depth match 058074 specifications.

What does the "MC" charge designation signify?
The MC charge indicates a medium temperature charge, typically used in applications where the evaporator temperature remains above freezing, such as reach-in coolers or mid-temp display cases.
