Emerson Flow Control (Alco) 059189 Power Head Assembly for R-404A Refrigerant with 5' Capillary

The Emerson Flow Control (Alco) 059189 is a replacement power head assembly designed for thermostatic expansion valves (TXVs) in commercial refrigeration systems using R-404A refrigerant. This power head features a 5-foot capillary tube that provides the sensing element for accurate temperature-based valve control.

Key Features:

• Engineered specifically for R-404A refrigerant applications
• 5-foot capillary tube length for flexible installation options
• Direct replacement power head for Alco thermostatic expansion valves
• Precision temperature sensing for optimal superheat control
• Durable construction for long-term reliability in commercial refrigeration environments

The power head assembly is a critical component that actuates the expansion valve based on suction line temperature, ensuring proper refrigerant flow and system efficiency. The 5-foot capillary allows for proper positioning of the sensing bulb on the suction line while maintaining accurate temperature response.
