Emerson Alco 035000 Power Assembly

When you're servicing legacy R12 systems or modern replacements, the Emerson Alco 035000 Power Assembly (model XC-726FW55-2B) is the reliable choice for maintaining precise superheat control. This T-Series take-a-part component is engineered for thermostatic expansion valve repair in demanding commercial refrigeration environments. Featuring a 10ft capillary tube length and 1/4" SAE flare external equalizer, it provides the responsive feedback required for stable evaporator performance across a wide application temperature range of -50°F to +50°F.

This assembly includes the necessary capscrews for a secure fit on Alco expansion valve bodies like the TER, TIR, and THR series. The 55 PSI MOP (Maximum Operating Pressure) charge is a critical safety feature, protecting the compressor motor from overload by limiting suction pressure during high-load periods or start-up. Whether you are performing a TXV power element replacement or a full system overhaul, this HVAC expansion valve part ensures the balanced flow necessary to prevent liquid slugging and maximize heat transfer efficiency.

• Universal Compatibility: Designed specifically for use with Emerson Alco T-Series valve bodies (TER, TIR, THR).
• Precise Pressure Control: The 55 PSI MOP charge provides essential compressor protection during high-load pull-downs.
• Durable Construction: Features a 10-foot capillary for flexible sensing bulb mounting in tight evaporator cabinets.
• Complete Kit: Includes high-grade capscrews to ensure a leak-free seal during field installation.
• Optimized for R12: Specifically calibrated for R12 refrigerant to maintain accurate superheat in older refrigeration circuits.

Is this power assembly compatible with refrigerants other than R12?
While optimized for R12, this power assembly is often used in systems converted to R134a or R401A, provided the 55 PSI MOP setting aligns with the new operating parameters. Always verify your saturation curves before installation.

What is the purpose of the 1/4" SAE flare connection?
This is for the external equalizer line, which allows the valve to sense pressure at the evaporator outlet. This is vital for systems with significant pressure drops across the distributor or coil.

Does this assembly include the internal orifice?
No, this is the power assembly only. The orifice cage must be matched separately to the required tonnage of the system.
