APC by Schneider Electric ACCD76059 141 kW Air-Cooled Condenser
Overview
The APC by Schneider Electric ACCD76059 is a 141 kW air-cooled condenser engineered for high-density data center and industrial cooling infrastructures where outdoor heat rejection capacity and electrical efficiency are primary design constraints. At 208–230 V, 3-phase, 60 Hz input, this unit integrates directly into standard North American commercial electrical infrastructure without requiring a transformer step-up — a real labor and cost savings on new builds. Explore the full APC by Schneider Electric cooling catalog for companion precision cooling units and UPS systems designed around the same architecture.
With a unit weight of 871.8 lb and a footprint of 11.6 ft wide × 52.9 in deep × 55.3 in tall, the ACCD76059 is sized for rooftop or ground-level pad installation alongside computer room air handlers (CRAHs) in a chilled-water or refrigerant-loop configuration. If you're sourcing a condenser to pair with precision cooling equipment, confirm your loop sizing matches the 141 kW rejection capacity before committing — oversizing the condenser relative to the indoor unit wastes fan energy and creates control instability.
Key Features
- 141 kW Cooling Capacity: This rejection capacity supports medium-to-large data center cooling loops — roughly the heat load of a dense 200–300 kW IT room depending on your COP target. Pair it carefully against your indoor CRAH nameplate to avoid unbalanced refrigerant pressure under peak load.
- Fixed and Variable-Speed, Low-Noise Fans: The hybrid fan array (fixed-speed for baseline airflow, variable-speed for modulation) trims energy draw during partial-load conditions — a meaningful operational savings over a purely fixed-speed array running 8,760 hours per year. The low-noise designation also matters if the unit is sited near occupied rooftops or property lines with noise ordinances.
- 95 °F Ambient / 120 °F Condensing Operating Range: The 95 °F ambient ceiling covers the majority of continental U.S. outdoor design temperatures, including hot-summer climates like Phoenix and Dallas. The 120 °F condensing limit sets the upper boundary for refrigerant head pressure — exceed it and your indoor compressor will fault on high-pressure cutout. Design your loop with this ceiling in mind.
- 208–230 V, 3-Phase, 60 Hz Input: Standard North American commercial power — no step-down transformer required. Three-phase input distributes load evenly across legs and keeps conductor sizing manageable at this wattage, reducing installation cost versus single-phase equivalent draws.
- RoHS and REACH Compliance: Both EU directives restrict hazardous substances and chemical reporting requirements. Relevant if you're deploying in facilities with environmental compliance mandates or operating under ESG procurement policies.
- 871.8 lb Unit Weight / 950 lb Shipping Weight: The 78 lb delta between shipping and operating weight is packaging only — factor the full 871.8 lb for structural loading calculations on rooftop pads or equipment platforms. Coordinate rigging and crane specs before delivery; this is not a unit that field crews hand-carry into position.
Integration and Compatibility
The ACCD76059 is designed to pair with APC's precision cooling indoor units — specifically CRAH units in the same kW class — as part of a closed-loop air-cooled refrigerant system. Confirm refrigerant compatibility, line-set sizing, and charge requirements with your mechanical contractor before procurement. For larger deployments, consider UPS systems from the same APC ecosystem to bring power protection and cooling under unified EcoStruxure management. If your facility runs a building management system (BMS), verify the condenser's control interface is supported — APC's precision cooling portfolio typically integrates via BACnet or Modbus depending on the controller revision.
For facilities planning thermal infrastructure from the ground up, pair this condenser with the appropriate power distribution units to ensure the electrical infrastructure feeding your cooling plant is sized for the full connected load — cooling draws are often underestimated in initial PDU sizing exercises.
Frequently Asked Questions
Q: What is the cooling capacity of the ACCD76059?
A: The ACCD76059 is rated at 141 kW of heat rejection capacity. It is designed for use in air-cooled refrigerant loop configurations paired with compatible indoor precision cooling units.
Q: What power supply does the ACCD76059 require?
A: The unit requires 208–230 V, 3-phase, 60 Hz input — standard North American commercial power. No step-up or step-down transformer is needed for typical U.S. commercial installations.
Q: What are the physical dimensions and weight of the ACCD76059?
A: The unit measures 55.3 in (H) × 11.6 ft (W) × 52.9 in (D) and weighs 871.8 lb. Shipping weight is 950 lb. Structural loading and rigging plans should be confirmed before delivery.
Q: What is the maximum ambient operating temperature for the ACCD76059?
A: The ACCD76059 is rated for ambient temperatures up to 95 °F, with a maximum condensing temperature of 120 °F. Designs for climates with high summer dry-bulb temperatures should verify these limits against local design-day conditions.
Q: Is the ACCD76059 RoHS and REACH compliant?
A: Yes. The ACCD76059 carries both RoHS and REACH compliance per the source evidence, making it suitable for facilities with EU-aligned environmental procurement policies.
Q: What fan technology does the ACCD76059 use?
A: The unit uses a combination of fixed-speed and variable-speed low-noise fans. The variable-speed fans modulate to reduce energy consumption during partial-load operation, which is relevant for sites with significant load variability across seasons or time of day.
The ACCD76059 is a straightforward specification for facilities engineers who have already committed to an air-cooled refrigerant loop architecture and need a 141 kW outdoor condenser that runs on standard 208–230 V 3-phase without additional transformer infrastructure. Where it earns its place is in mid-size data centers and edge deployments where chilled-water systems are cost-prohibitive and the site's electrical distribution already supports 3-phase commercial feeds.
Technical Highlights:
- 141 kW Rejection at 95°F Ambient: That ambient ceiling covers most continental U.S. design days — Phoenix peaks around 110–115 °F but design-day dry-bulb for ASHRAE 1% design is closer to 109 °F, which starts to push this unit's limits. Confirm your local design-day data before specifying for extreme-heat climates.
- Variable-Speed Fan Modulation: The hybrid fixed/variable fan array keeps part-load efficiency meaningful. A condenser running at 60% load in shoulder seasons or at night can shed significant fan kWh annually — over 8,760 annual hours, that delta compounds into real energy cost on a utility bill.
- 871.8 lb Operating Weight: Rigging is not optional here. The 78 lb packaging delta means the unit arrives at 950 lb — confirm crane access, pad reinforcement ratings, and vibration isolation mounts before the unit ships, not after it's on site.
Deployment Considerations:
- This unit pairs with APC's indoor precision cooling CRAH lineup — verify refrigerant type and charge requirements match your indoor unit before ordering. Mismatched refrigerants in a pre-charged loop are an expensive field problem.
- The 120 °F condensing limit is a hard ceiling, not a design target. If your refrigerant loop runs consistently near that limit due to undersized line sets or high ambient conditions, the indoor compressor will fault on high-pressure cutout before the condenser fails — design with headroom.
The ACCD76059 is best suited for rooftop or ground-pad deployments at single-floor or co-location data centers in the 150–300 kW IT load range, where a chilled-water plant is not justified but the thermal rejection load exceeds what smaller split systems can handle cost-effectively.
