APC by Schneider Electric ACRD601 InRow RD 600mm Air-Cooled Data Center Cooling Unit
Overview
The ACRD601 is APC by Schneider Electric's InRow RD 600mm air-cooled precision cooling unit designed for high-density data center rows. Running on 460/480V at 60Hz, this unit deploys directly alongside server racks to deliver targeted cooling exactly where heat is generated — rather than relying on perimeter cooling that leaves hot spots between aisles. At 42U tall and 23.6 inches wide (600mm), it fits a standard rack footprint, letting you integrate cooling capacity into the row without dedicating separate floor space to remote CRAC units. For enterprise data centers, colocation facilities, or large network operations centers scaling beyond what perimeter cooling can handle, the ACRD601 represents a purpose-built data center cooling solution sized for production deployments.
Key Features
- 460/480V Input at 60Hz: This is a North American three-phase voltage unit — confirm your facility's electrical infrastructure before specifying. Three-phase 460/480V distribution is standard in purpose-built data centers and allows the unit to draw the same power budget as adjacent APC by Schneider Electric UPS and PDU equipment on a shared electrical plan.
- 600mm (23.6-inch) Cabinet Width: Matches the physical footprint of a standard 600mm-wide server rack, so the InRow unit slots directly into a row without gap panels or custom framing. This matters during aisle containment buildouts where physical alignment between racks and cooling units determines containment integrity.
- 42U Nominal Height (78.4 inches): Full rack height ensures the cooling column spans the same vertical extent as the server racks flanking it, which is critical for hot-aisle/cold-aisle containment to function correctly. A shorter unit leaves an unsealed gap at the top that bleeds conditioned air into the hot aisle.
- R410A Refrigerant: R410A is the current industry-standard refrigerant for precision cooling equipment of this class. It delivers higher efficiency than legacy R22 systems and is widely serviceable by qualified data center mechanical contractors. Note that R410A has a planned phase-down timeline under EPA regulations — factor this into long-term facility planning for units expected to operate beyond 2030.
- 862 lb Installed Weight: At 862 pounds, floor loading is a real constraint. Verify your raised floor or concrete slab rating before deployment — most raised floor systems specify 250–300 lb per square foot, but concentrated point loads from a unit this heavy require engineering review, especially on older raised floor grids.
- 42.1-inch Depth (Length): The unit extends 42.1 inches front-to-back. In aisle containment deployments, this depth must be accounted for in overall row length planning to ensure containment doors close flush and airflow paths aren't compromised.
Integration and Compatibility
The ACRD601 is designed for integration into APC InRow cooling architectures and is intended to be managed alongside APC's broader power distribution and monitoring ecosystem. InRow RD units in the ACRD6xx family are typically managed via APC's EcoStruxure IT or NetBotz environmental monitoring platforms, enabling centralized temperature, airflow, and energy monitoring across the data center row. Pairing with APC network management cards allows SNMP/web-based remote monitoring — confirm exact management card compatibility with APC for this voltage variant before procurement. The 460/480V electrical requirement means this unit is not interchangeable with the 208V variants in the InRow RD family; ensure your mechanical and electrical contractors are spec'd to the correct model from the outset.
Frequently Asked Questions
Q: What voltage is required to operate the ACRD601?
A: The ACRD601 requires 460/480V at 60Hz — this is a three-phase North American voltage unit. It is not compatible with 208V single-phase or standard 120V circuits. Confirm your facility's electrical distribution before specifying this model.
Q: What refrigerant does the ACRD601 use?
A: The ACRD601 uses R410A refrigerant, the current standard for precision cooling equipment of this class. It is widely serviceable but subject to EPA phase-down timelines; factor this into long-term facility planning for deployments expected to run beyond 2030.
Q: What is the physical footprint of the ACRD601?
A: The unit is 600mm (23.6 inches) wide, 78.4 inches tall (42U), and 42.1 inches deep. It weighs 862 pounds installed, which requires floor loading verification before placement.
Q: Is the ACRD601 compatible with hot-aisle/cold-aisle containment systems?
A: Yes — the 42U full rack height and 600mm width are specifically sized to integrate with standard row-based containment architectures. The unit's dimensions must align with adjacent racks to ensure containment integrity; gaps in height or width will compromise aisle separation.
Q: Can the ACRD601 be managed remotely?
A: InRow RD units are designed for integration with APC's EcoStruxure IT and NetBotz environmental monitoring platforms. Remote management capability typically requires compatible APC network management cards — confirm specific card compatibility with APC for this voltage variant before ordering.
The ACRD601 is a unit I'd spec specifically when you're dealing with three-phase 460/480V electrical infrastructure and need InRow cooling to fit a 600mm rack row. At 862 pounds and 42.1 inches deep, this isn't a unit you drop into a small server room — it's engineered for purpose-built data center environments where row-based cooling architecture is already part of the design. The ACRD601's 42U height is the detail that makes or breaks containment: if you're building a hot-aisle containment enclosure, every rack and cooling unit in that row needs to be the same height or you're engineering air bypass back into the system.
Technical Highlights:
- 460/480V Three-Phase Input: This voltage requirement is non-negotiable at the electrical planning stage — the 460/480V variant draws from three-phase distribution infrastructure standard in enterprise data centers, but it means this unit cannot be shared across sites with 208V infrastructure without a separate model specification.
- 600mm / 23.6-inch Width: Exact match to standard 600mm rack width means no gap panels, no custom framing — the unit integrates cleanly into the row for containment alignment. Any width mismatch in an InRow deployment is a containment failure waiting to happen.
- R410A Refrigerant: Widely available and serviceable today, but the EPA's phase-down schedule for R410A is a real facilities planning factor. For a unit this size and investment level, confirm your mechanical contractor's servicing position on R410A availability in your region over the expected equipment lifecycle.
Deployment Considerations:
- At 862 lb, floor loading review is mandatory before placement — particularly on raised floor grids rated for distributed loads rather than concentrated point loads. Engage your structural engineer or raised floor vendor before finalizing the deployment plan.
- The 460/480V input means electrical infrastructure must be confirmed early in the project — this is not a unit you can substitute with a lower-voltage model at the last stage of a build without redesigning the branch circuit.
The ACRD601 is the right specification for enterprise data centers and colocation facilities running three-phase 460/480V distribution where row-based precision cooling needs to integrate directly into a 600mm rack row without physical compromise to aisle containment architecture.
