APC by Schneider Electric ACAC75014 Flooded Receiver 20L ASME with Heater
Overview
The APC by Schneider Electric ACAC75014 is a 20-liter flooded receiver engineered for refrigerant liquid-line storage in commercial cooling and precision air systems. At 219mm in diameter and 640mm in length, it occupies a well-defined footprint that integrates into rack-mounted and floor-standing precision cooling infrastructure without requiring structural modification. The integrated heater prevents refrigerant migration during off-cycles — a common source of compressor slugging in facilities where ambient temperatures drop significantly.
The ASME pressure vessel certification means this unit has been independently validated to the American Society of Mechanical Engineers Boiler and Pressure Vessel Code — a hard requirement for many commercial and industrial installations where a jurisdiction authority having jurisdiction (AHJ) mandates code-stamped components. If your project specs call for ASME-certified receivers, the ACAC75014 satisfies that requirement without a field waiver or engineering exception.
Key Features
- 20-Liter Capacity: Sized to handle refrigerant charge storage for mid-range precision cooling units — enough buffer to absorb load-shift transients without starving the expansion valve or triggering low-pressure lockouts on the compressor.
- 219mm Diameter / 640mm Length: Compact cylindrical form factor designed to fit within standard APC precision cooling enclosures; the 219mm diameter aligns with common receiver mounting saddle dimensions, reducing field-fabricated bracket work.
- ASME Pressure Vessel Certification: Code-stamped to ASME standards, satisfying jurisdictional AHJ requirements on commercial HVAC/R projects. Eliminates the need for third-party re-certification or field engineering sign-off in most US jurisdictions.
- Integrated Heater: Prevents refrigerant pooling and migration to the compressor crankcase during extended off-cycles — particularly relevant in data center environments where cooling systems cycle frequently with variable IT loads.
- 2-Input / 2-Output Alarm I/O: The 2/2 alarm I/O configuration lets you wire pressure-fault or heater-fault signals directly into a BMS or building automation system, so a receiver-side anomaly generates an alert in your monitoring dashboard rather than a silent failure.
- Flooded Receiver Design: Maintains a liquid refrigerant head above the outlet, ensuring consistent subcooling delivery to the expansion device — critical for stable system efficiency across varying load conditions in data center cooling applications.
Integration and Compatibility
The ACAC75014 is designed as a component within APC by Schneider Electric precision cooling system architectures. The 2/2 alarm I/O terminals support integration with building management systems and EcoStruxure-based monitoring platforms. Installers should verify refrigerant type compatibility and system charge capacity against the host cooling unit's engineering documentation before commissioning. The ASME stamp facilitates permit-driven installation on projects where the mechanical permit requires code-certified pressure vessels — coordinate with the AHJ early if your jurisdiction enforces ASME B&PV Code Section VIII.
Frequently Asked Questions
Q: Is the ACAC75014 ASME certified?
A: Yes. The ACAC75014 is rated and stamped to ASME pressure vessel standards, satisfying most US jurisdictional AHJ requirements for commercial HVAC/R installations without additional field certification.
Q: What is the capacity and physical size of the ACAC75014?
A: The ACAC75014 has a 20-liter flooded receiver capacity, measures 219mm in diameter and 640mm in length.
Q: Does the ACAC75014 include a heater?
A: Yes. An integrated heater is included to prevent refrigerant migration during system off-cycles, protecting the compressor from liquid slugging.
Q: What alarm I/O does the ACAC75014 provide?
A: The unit provides 2 alarm inputs and 2 alarm outputs (2/2), enabling integration with building management or monitoring systems for fault alerting.
Q: What cooling system types is the ACAC75014 designed for?
A: The ACAC75014 is designed for use within APC by Schneider Electric precision cooling systems, including data center and commercial facility deployments requiring ASME-compliant refrigerant receivers.
The ACAC75014 is a component-level purchase that shows up on projects where the mechanical contractor or data center facilities team needs an ASME-stamped flooded receiver to satisfy the AHJ permit review — and needs it to drop into an existing APC precision cooling system without field engineering surprises. The 20L capacity and 219mm diameter are not arbitrary; they are sized to the host system's refrigerant charge and enclosure geometry.
Technical Highlights:
- 20L Flooded Design: Maintains a liquid head at the outlet at all load points, delivering consistent subcooling to the expansion valve — reduces efficiency degradation during partial-load operation common in variable IT-load data halls.
- Integrated Heater: Addresses refrigerant migration during off-cycles proactively rather than relying on crankcase heaters alone — relevant in environments with frequent start/stop cycling or wide ambient temperature swings.
- 2/2 Alarm I/O: Direct BMS wiring path for pressure or heater fault signals; keeps receiver health visible in the facility monitoring layer without adding a separate monitoring module.
Deployment Considerations:
- Confirm refrigerant type and charge volume compatibility with the host APC cooling unit before ordering — the 20L capacity is fixed and must match the system design charge.
- The ASME stamp covers the vessel itself; associated piping, relief valves, and isolation valves must meet local code independently — the receiver alone does not make the full assembly compliant.
This unit is the right call on data center retrofit or new-build projects where the AHJ requires ASME-certified pressure vessels and the host system is within the APC precision cooling family — skip it if you are working outside that ecosystem.
