Copeland Comfort Control (Alco) 099022 Pressure Control

The Copeland Comfort Control 099022 (formerly Alco/Emerson Flow Control) is a professional-grade PS1 Series Single Pressure Control designed for high-precision low-pressure monitoring. This PS1-X3A low pressure control serves as the direct replacement for 097894, offering an adjustable setpoint range from 9"Hg to 102 psig. Built for heavy-duty commercial refrigeration and HVAC applications, it utilizes an auto reset mechanism to ensure continuous system operation without manual intervention after a pressure trip. The 1/4" SAE male flare connection provides a reliable, leak-resistant interface with the refrigerant line. With a robust differential range of 15 to 73 psig, this low pressure switch allows technicians to fine-tune compressor cycling and protect against suction pressure drops. Whether you are servicing a walk-in cooler or a rooftop unit, this OEM component delivers the repeatability and field durability required by contractors.

Key Benefits:

• Broad Compatibility: Functions as an OEM replacement for legacy Alco and Emerson PS1-X3A models.
• Precision Calibration: Wide setpoint range of 9"Hg to 102 psig allows for versatile pressure management across various refrigerants.
• Durable Construction: High-cycle life bellows and snap-action SPDT contacts provide reliable switching in demanding environments.
• Tool-Free Adjustments: Features visible scales for both setpoint and differential, simplifying field configuration.
• Automatic Reset: Eliminates unnecessary truck rolls by automatically clearing the fault once pressures return to the safe operating range.

Common Questions:

Can the 099022 be used on high-pressure applications?
No, this is a low pressure control specifically designed for suction side monitoring and protection. For high-side discharge protection, a PS1 or PS2 high-pressure series control should be utilized.

What is the contact rating for the SPDT switch?
The internal SPDT switch is typically rated for 120/240V AC applications, capable of handling inductive loads common in compressor contactor circuits and alarm signals.

Is this part compatible with modern HFC and HFO refrigerants?
Yes, the Emerson PS1 Series is compatible with most non-corrosive refrigerants, including R-22, R-134a, R-404A, R-407C, and R-410A.
