Emerson Alco 058085 Power Element

For service technicians and contractors maintaining low-temperature refrigeration systems, the Emerson Alco 058085 Power Element (X26300-SW45-1) is a critical replacement component for HF and HFK series thermostatic expansion valves. This high-performance TXV power head is engineered to provide precise superheat control in demanding environments. Featuring a 5-foot capillary tube, it allows for flexible remote bulb mounting, ensuring accurate sensing of the suction line temperature. The element is specifically designed for R404A, R507, and R502 refrigerants, making it a versatile choice for commercial walk-in freezers and reach-in cases.

The X26300-SW45-1 utilizes a low-temperature MOP (Maximum Operating Pressure) charge rated at 45 PSIG. This pressure-limiting feature is vital for protecting the compressor from overloading during high-load periods or post-defrost pulldown by capping the maximum suction pressure. Built with stainless steel construction, this 058085 Alco power element offers superior corrosion resistance and long-term durability in moisture-heavy refrigeration environments. When your refrigeration expansion valve requires a rebuild, this OEM element ensures the balanced port valve maintains peak system efficiency and reliable evaporator performance.

• Optimized System Protection: The W45 MOP charge limits suction pressure to 45 PSIG, preventing compressor motor overload during startup.
• Broad Refrigerant Compatibility: Designed specifically for high-pressure refrigerants including R404A, R507, and legacy R502 systems.
• Durable Construction: The stainless steel power head resists corrosion and ensures hermetic integrity in harsh conditions.
• Flexible Installation: The 5' capillary tube allows for optimal bulb placement on the suction line, even in tight evaporator housings.
• OEM Precision: Guaranteed compatibility with Emerson HF and HFK series valve bodies for a leak-free, drop-in replacement.

What is the purpose of the SW45 MOP charge on this element?
The SW45 charge provides a Maximum Operating Pressure limit of 45 PSIG. This prevents the expansion valve from feeding excess refrigerant during high-load conditions, such as after a defrost cycle, which protects the compressor from high suction pressure.

Is this power element compatible with R22 systems?
No, the X26300-SW45-1 is specifically calibrated for the pressure-temperature curves of R404A, R507, and R502. Using it with other refrigerants will result in incorrect superheat settings and potential system failure.

Can I use this on an HFK series balanced port valve?
Yes, this is a standard replacement power element for both HF (fixed) and HFK (take-apart) series valves, provided the refrigerant and temperature requirements match the system specifications.
