APC by Schneider Electric ACRC301S InRow RC 300mm Chilled Water Cooling Unit
Overview
The ACRC301S is APC by Schneider Electric's InRow RC 300mm chilled water cooling unit, designed for close-coupled cooling in high-density data center rows. The 300mm slim footprint lets it slot directly into a standard equipment row without consuming a full rack bay, keeping cooling proximity tight to the heat load — a real advantage over raised-floor or perimeter approaches in modern high-density deployments. The universal 100-240V, 50/60 Hz input means it can be provisioned in virtually any facility power environment without special transformer infrastructure.
The chilled water design separates the heat rejection path from the air side entirely: facility chilled water does the heavy lifting, so there is no refrigerant circuit to manage, no compressor to maintain, and no DX charge to worry about. That translates to lower long-term maintenance overhead compared to direct-expansion in-row units and is a common reason data center engineers specify chilled water for sustained high-density loads.
For complete technical specifications — cooling capacity (kW), airflow (CFM/m³/h), supply and return water temperatures, static pressure, and physical dimensions — consult the APC by Schneider Electric product datasheet for the ACRC301S directly from the manufacturer. Specifications should be verified against your facility's chilled water plant capacity and row layout before procurement.
Key Considerations
- 300mm form factor: Narrow footprint integrates into a standard 600mm-deep row without a dedicated full-rack footprint, preserving usable rack space in the row.
- Chilled water cooling: No on-board refrigerant circuit means no compressor maintenance, no DX leak risk, and cooling capacity scales with facility plant — not with the unit itself.
- Universal input voltage: 100-240V / 50-60 Hz acceptance removes site-specific power constraints and simplifies global deployment or future facility moves.
- InRow proximity: Close-coupled deployment reduces hot/cold aisle bypass and improves cooling effectiveness compared to perimeter or ceiling units in high-density rows.
Frequently Asked Questions
Q: What does the ACRC301S cool — what is its rated capacity?
A: Cooling capacity specifications are not included in the available evidence for this listing. Consult the APC by Schneider Electric official datasheet for the ACRC301S for kW ratings, airflow, and water flow requirements before sizing your deployment.
Q: What type of cooling does the ACRC301S use?
A: The ACRC301S uses chilled water cooling. It connects to your facility's chilled water plant rather than using an on-board refrigerant circuit or compressor.
Q: What is the input voltage requirement for the ACRC301S?
A: The ACRC301S accepts 100-240V, 50/60 Hz — a universal input range compatible with standard single-phase facility power in most regions.
Q: How wide is the ACRC301S?
A: The ACRC301S is a 300mm-wide InRow RC unit, designed to fit within a standard data center row alongside equipment racks. Verify rack row dimensions against the manufacturer datasheet before ordering.
The ACRC301S is APC's 300mm InRow RC chilled water unit — and the 300mm width is the spec that drives most of the purchasing decisions I see on this model. When a row layout is already tight and you need close-coupled cooling without surrendering a full 600mm rack slot, that slim form factor is the primary reason engineers reach for this SKU over wider in-row alternatives.
Technical Highlights:
- Chilled water circuit: No on-board compressor or refrigerant charge means the mechanical maintenance profile is dramatically simpler than DX alternatives — no refrigerant certification required for service, no leak detection system needed at the unit level.
- 100-240V universal input: Facility power flexibility is built in from the start; no step-down transformer required across standard global voltages, which matters when you are deploying across multiple sites or planning a facility refresh.
- 300mm InRow form factor: Close-coupled placement keeps supply air at the inlet face of servers rather than traversing the room — a measurable improvement in cooling effectiveness per kW delivered in high-density rows versus perimeter cooling.
Deployment Considerations:
- Chilled water units require a facility chilled water plant with sufficient capacity and compatible supply/return temperatures — confirm your plant specs against the APC datasheet before committing to this unit in a new data center build or retrofit.
- Available source evidence for this SKU is limited to product name and model number; full cooling capacity (kW), airflow, water flow rate, and physical dimensions must be verified directly against the manufacturer datasheet prior to procurement and installation design.
The ACRC301S is the right call for high-density colocation rows or enterprise server rooms where close-coupled chilled water cooling is already part of the facility infrastructure and row space is at a premium — not a general-purpose pick for environments without an existing chilled water plant.
