Emerson Alco 097815 Pressure Control

The Emerson Alco 097815, also known by model PSC-AJS, is a high-precision mini low pressure control engineered for critical refrigeration and air conditioning safety. This heavy-duty Emerson pressure switch features an auto reset mechanism and a versatile SPDT switch configuration, allowing for seamless integration into both control and alarm circuits. With a wide adjustable range of 15" wc to 90 PSI and a factory-set differential, this unit is designed to protect compressors from low-suction conditions and avoid equipment failure. The 1/4" flare with valve depressor ensures a secure, leak-free connection directly to the system's access port. For simplified field installation, this 0097815 identical model includes a DIN plug and 36" cable connection, providing superior strain relief and environmental protection compared to standard terminal lugs. Built to withstand commercial R-410A and HFC applications, this PSC-AJS low pressure control delivers the reliable, repeatable performance professional contractors require for system longevity.

• Enhanced System Protection: Safeguards compressors against low refrigerant charges and evaporator freeze-ups.
• Versatile Electrical Logic: The SPDT contact arrangement supports both system shutdown and remote alarm notification.
• Rapid Installation: Pre-wired 36-inch cable and DIN plug reduce labor time on the job site.
• Compact Form Factor: The mini-size design allows for installation in tight mechanical headers and compact condensing units.
• Internal Valve Depressor: Eliminates the need for separate schrader valve tools during high-pressure side mounting.

Is the 097815 compatible with 0097815?
Yes, these two part numbers are identical in specifications, fit, and function.

Can this be used for condenser fan cycling?
While primarily a low-pressure safety, the SPDT switch and 15-90 PSI range allow it to be utilized for specific fan cycling applications depending on refrigerant pressures.

What is the maximum overpressure for this control?
This low pressure control is rated for a maximum overpressure of up to 360 PSIG, ensuring durability during system pressure spikes.
