APC by Schneider Electric ACFC75266 112kW Roof-Mounted Fluid Cooler
Overview
The APC by Schneider Electric ACFC75266 is a roof-mounted evaporative fluid cooler rated at 112kW of heat rejection capacity at 110°F–120°F ambient conditions — built for data center and critical infrastructure environments where mechanical cooling must keep pace with dense compute loads under high ambient temperatures. At 549.5 kg and spanning 3,528 mm wide, this is a purpose-engineered rooftop unit designed for facilities teams commissioning large-scale thermal management systems, not a retrofit appliance. If your project involves a new data hall build-out or a major capacity upgrade in a warm climate, the ACFC75266 belongs on the short list for evaluation alongside your MEP engineer.
The unit runs on three-phase power infrastructure at 208–230V, 60 Hz — the standard voltage range for North American commercial electrical distribution. That means no step-up transformer is required for most US facilities operating standard 208V three-phase panels, which simplifies both the electrical design and the ongoing utility relationship. Three-phase input at this scale also distributes load evenly across phases, reducing demand spikes on your electrical infrastructure during startup cycles.
Key Features
- 112kW Cooling Capacity at 110°F–120°F: This rating specifies performance under genuinely high ambient conditions — not a sea-level, 70°F lab number. If your rooftop ambient regularly hits triple digits in summer (desert Southwest, industrial sites, high-density urban rooftops), a capacity figure qualified at those temperatures tells you what the unit will actually deliver when you need it most, not what it delivers on a cool day.
- Roof-Mount Form Factor: Locating the cooler on the roof keeps heat rejection outside the building envelope entirely, eliminating the recirculation risk you get with ground-level units placed too close to air intakes. It also frees up the building perimeter for other infrastructure and simplifies access control around critical equipment.
- 208–230V, 3-Phase, 60Hz Input: The wide voltage window (208–230V) accommodates real-world voltage sag on loaded distribution panels without tripping on undervoltage faults. For facilities running 208V three-phase from a 480/277V main — common in US commercial construction — this unit connects directly without additional power conversion hardware.
- Evaporative Cooling Design: Evaporative fluid coolers leverage the thermodynamics of water evaporation to achieve heat rejection efficiencies that dry coolers cannot match at high ambient temperatures. In climates where wet-bulb temperatures are significantly lower than dry-bulb, this translates into either higher capacity at the rated condition or reduced energy consumption at partial load — both relevant for annual PUE calculations.
- Physical Footprint — 3,528 × 1,344 mm: At roughly 11.6 ft wide and 4.4 ft deep, structural and crane planning are non-trivial. The shipping package extends to 3,683 × 1,524 mm, so dock clearance and rigging radius both need to be confirmed before scheduling the delivery. Structural engineering review of the roof deck load capacity — accounting for the 549.5 kg operating weight plus snow/wind loads — is a required step, not optional.
- 549.5 kg Operating Weight: Rooftop structural loading at this mass class typically requires a formal load calculation from a structural engineer. Factor in dynamic loads from fan vibration in addition to the static weight when specifying isolation pads and curb mounting hardware.
Integration and Compatibility
The ACFC75266 is a mechanical cooling component designed to integrate into a broader data center cooling infrastructure — typically as part of a fluid-side loop paired with computer room air handlers (CRAHs), rear-door heat exchangers, or in-row cooling units on the floor. Compatibility with your specific piping design, glycol concentration, and flow rate targets needs to be confirmed with the facility's MEP engineer and the APC product documentation before procurement. This unit is not a plug-and-play appliance; commissioning involves fluid system integration, controls wiring, and startup verification by qualified mechanical contractors.
For larger deployments evaluating full APC by Schneider Electric power and cooling solutions — including UPS systems, PDUs, and rack enclosures — coordinating the cooling and power infrastructure from a single vendor can simplify controls integration and service coverage.
Frequently Asked Questions
Q: What is the cooling capacity of the ACFC75266 and under what conditions is it rated?
A: The ACFC75266 is rated at 112kW of heat rejection capacity at ambient conditions of 110°F to 120°F. This is a high-ambient rating — it reflects what the unit delivers under hot rooftop conditions, not a controlled lab baseline.
Q: What electrical supply does the ACFC75266 require?
A: The unit requires three-phase power at 208–230V, 60 Hz. This aligns with standard North American commercial three-phase electrical distribution, making it compatible with most US data center and industrial facility electrical infrastructure without step-up transformers.
Q: How much does the ACFC75266 weigh, and what are the physical dimensions?
A: The operating weight is 549.5 kg (approximately 1,211 lbs). Dimensions are 3,528 mm wide × 1,344 mm deep × 1,405 mm tall. Shipping package dimensions are 3,683 × 1,524 × 1,524 mm at 613.6 kg. Roof structural review and crane/rigging planning are required before installation.
Q: Is the ACFC75266 designed for indoor or outdoor installation?
A: The ACFC75266 is a roof-mounted unit — it is designed for outdoor installation on a rooftop, rejecting heat outside the building envelope. It is not an indoor unit.
Q: Does the ACFC75266 require a water supply for operation?
A: As an evaporative fluid cooler, the unit uses water evaporation as part of its heat rejection process. The specification confirms the removable water tank option is not present on this model (listed as 'No'), which indicates the water supply is handled via the building's plumbing connection rather than a standalone tank — confirm water supply and treatment requirements with your MEP engineer during system design.
The ACFC75266 is one of those units where the rated condition matters as much as the rated number. A 112kW capacity figure qualified at 110°F–120°F ambient is a fundamentally different data point than a rating taken at 70°F — it tells you this unit was sized and validated for hot rooftop environments, not just favorable test conditions. If you're specifying cooling for a data hall in Phoenix, Las Vegas, or a sun-exposed industrial rooftop in the Southeast, that ambient qualification is the spec that earns this unit a spot on the equipment schedule.
Technical Highlights:
- 112kW at High Ambient: Heat rejection capacity rated at 110–120°F means you get the published number on your worst summer days — the times your cooling infrastructure is under maximum load and failure costs the most.
- 208–230V Three-Phase, 60Hz: The voltage window absorbs real-world distribution sag without nuisance trips; no step-up transformer required for standard US 208V three-phase panels, which keeps the electrical BOM clean.
- 549.5 kg Operating Weight: This is a 1,211-lb rooftop load — structural engineering sign-off is non-negotiable before installation. Factor dynamic fan loads on top of static weight when specifying the curb and isolation mounts.
Deployment Considerations:
- The 3,528 mm wide shipping footprint means you need to confirm crane swing radius, roof hatch or staging area dimensions, and dock clearance well in advance — this is a logistics coordination project, not a drop-ship installation.
- The water supply connection (no removable tank on this model) requires building plumbing integration and a water treatment plan; evaporative coolers are sensitive to mineral scaling and biological growth without proper chemical treatment, which directly affects long-term capacity and maintenance intervals.
This unit is the right specification anchor for a new data hall build in a warm-climate region where rooftop ambient temperatures routinely exceed 100°F — particularly colocation facilities, edge data centers in the Sun Belt, or industrial control rooms where wet-bulb advantage makes evaporative cooling the economically correct choice over compressor-based alternatives.
