Emerson Alco 095813 Power Assembly

The Emerson Alco 095813 is a high-performance TLE-Series Power Assembly engineered for precision refrigerant flow control in R22 HVAC systems. This specific component, synonymous with model XB-1033HW100-1B, features a 1/4" flare external equalizer and a 5' capillary tube length to ensure versatile mounting options and accurate pressure sensing. A critical technical feature is the MOP 100 PSI (Maximum Operating Pressure) setting, which protects the compressor from overload during high-load conditions or startup. Designed for field replacement or new system builds, this power assembly provides the mechanical feedback necessary for consistent evaporator superheat regulation. Its rugged stainless steel construction minimizes the risk of diaphragm fatigue, ensuring the thermostatic expansion valve (TXV) maintains system equilibrium. Professionals utilize this model for its reliable MOP charging characteristics, which are essential for preventing suction pressure spikes in R22 applications.

Key Technical Benefits:

• System Compatibility: Correctly calibrated for R22 refrigerant systems requiring external equalization.
• Compressor Protection: Integrated MOP 100 PSI charge prevents motor overload during high-suction pressure transients.
• Durable Construction: Features a corrosion-resistant stainless steel diaphragm for long-term cycle life.
• Flexible Installation: The 5-foot capillary tube allows for optimal remote bulb placement away from turbulent airflows.
• Direct Interchangeability: Unit is the exact replacement for the XB-1033HW100-1B specification.

Common Technical Questions:

What is the purpose of the 100 PSI MOP on this power assembly?
The Maximum Operating Pressure (MOP) feature limits the expansion valve's opening once suction pressure exceeds 100 PSI, protecting the compressor motor from excessive torque during hot-start conditions.

Can I use the Emerson 095813 on an internally equalized valve body?
No, this unit is designed specifically for external equalizer configurations. Using it on an internal equalizer body will result in inaccurate superheat control and potential system hunting.

Will this work with refrigerants other than R22?
This power head is cross-ambient charged specifically for the pressure-temperature curve of R22. Using it with other refrigerants will lead to improper valve modulation and possible liquid slugging.
