APC by Schneider Electric ACCD76057 101kW 3-Phase Airflow System Condenser
Overview
The ACCD76057 is APC by Schneider Electric's 101kW airflow system condenser designed for high-density data center and enterprise infrastructure environments where heat rejection capacity and ambient temperature tolerance are non-negotiable. Rated to operate at ambient conditions up to 120°F (49°C), this unit is built for hot outdoor equipment rooms, rooftop mechanical enclosures, and industrial facilities where standard condensers fail under summer peak loads. At 101kW of cooling capacity, it pairs with APC's in-row and containment cooling systems to handle the thermal output of densely populated server aisles or power-intensive UPS and battery environments. If you're sizing cooling infrastructure for a greenfield data center build or expanding capacity on an existing hot aisle/cold aisle layout, the ACCD76057 belongs on your short list of data center cooling equipment.
Key Features
- 101kW Cooling Capacity: That's enough to handle the heat load of roughly 80–100 densely populated 1U servers or a fully loaded UPS row — meaningful for mid-sized data centers or large edge deployments where a single undersized condenser creates cascading thermal throttling across the entire rack row.
- 120°F (49°C) Rated Ambient: Most commercial condensers are rated to 95°F or 105°F. The ACCD76057's 120°F upper limit means it remains operational during extreme summer heat events without derate — critical for rooftop-mounted installations in hot climates or unconditioned mechanical rooms that regularly see temperatures above 100°F.
- 95°F (35°C) Standard Operating Condition: The unit is designed around a 95°F ambient baseline, meaning full 101kW capacity is available at that condition. This aligns with ASHRAE A2 classification requirements and ensures predictable performance modeling during capacity planning.
- 208-230V / 3-Phase / 60Hz Power Input: Three-phase input at 208–230V is standard for commercial electrical infrastructure in North American data centers. This eliminates the need for step-up or step-down transformers and integrates directly with typical PDU and switchgear configurations. Confirm your facility's 3-phase availability before ordering — this unit will not operate on single-phase supply.
- 245.4 kg Unit Weight: At 541 lbs, structural planning is mandatory. Rooftop or raised-floor installations require load calculations before mounting. Factor this into your mechanical engineering review early in the project — not after the unit arrives on site.
- Part of APC's Airflow Management Ecosystem: The ACCD76057 is designed to integrate with APC by Schneider Electric's broader cooling and containment architecture, including in-row coolers, hot aisle containment systems, and EcoBreeze economizers, allowing phased capacity expansion as rack density grows.
Integration & Compatibility
The ACCD76057 is engineered as a condenser component within APC's modular cooling infrastructure. It pairs with APC in-row cooling units that require an external condenser for heat rejection — the condenser handles the refrigerant-side heat exchange, while the indoor unit manages airflow directly at the rack level. This split architecture keeps the noise and heat-rejection hardware outside the data hall, which matters in colocation environments and facilities with strict acoustic requirements.
Three-phase 208-230V power infrastructure is required. Coordinate with your facilities team on dedicated circuit sizing, disconnect requirements, and conduit routing before scheduling delivery. Given the 272.7 kg (601 lb) packaged weight, verify freight elevator capacity and floor load ratings on the delivery path — this is not a unit that gets hand-trucked into a basement MER without a plan.
For organizations managing mixed cooling deployments, the ACCD76057 fits within Schneider Electric's EcoStruxure architecture, which enables centralized monitoring and thermal management across multiple cooling zones from a single management platform. Check with your infrastructure planning team on integration with existing DCIM tools before commissioning.
Frequently Asked Questions
Q: What is the maximum ambient temperature the ACCD76057 can operate in?
A: The ACCD76057 is rated for operation up to 120°F (49°C) ambient. This makes it suitable for outdoor rooftop installations and unconditioned mechanical rooms in hot climates that would exceed the limits of standard condensers.
Q: Does the ACCD76057 require 3-phase power, or can it run on single-phase supply?
A: The ACCD76057 requires 3-phase power at 208-230V, 60Hz. Single-phase supply is not compatible with this unit. Confirm your facility has appropriately sized 3-phase circuits and a dedicated disconnect before ordering.
Q: What is the cooling capacity of the ACCD76057?
A: The ACCD76057 delivers 101kW of cooling capacity, rated at a 95°F (35°C) standard ambient condition, with continued operation rated up to 120°F (49°C).
Q: How heavy is the ACCD76057, and what does that mean for installation planning?
A: The unit weighs 245.4 kg (541 lbs) unpackaged and 272.7 kg (601 lbs) in packaging. Structural load assessments for rooftop or raised-floor installations are mandatory. Coordinate with your mechanical engineer and facilities team before scheduling delivery or rigging.
Q: Is the ACCD76057 designed to work with APC's in-row cooling systems?
A: Yes. The ACCD76057 functions as the external condenser in APC's split cooling architecture, designed to pair with APC in-row coolers that route refrigerant to an outdoor or remote condenser for heat rejection. Verify compatibility with your specific in-row cooler model number before purchasing.
The ACCD76057 is one of the relatively few commercial condensers I've spec'd that carries a legitimate 120°F ambient rating — not a derated capacity number at that temperature, but a stated operational upper limit. For a client running a rooftop-mounted split cooling system in Phoenix or Houston, that distinction matters a lot when you're trying to maintain SLA uptime through a July heat event. At 101kW, this unit has the capacity to serve as the sole condenser for a mid-density data hall or to act as one node in a redundant N+1 cooling topology for larger deployments.
Technical Highlights:
- 101kW Rated Capacity: Enough heat rejection for a fully loaded in-row cooler serving 20–25 high-density racks — size your refrigerant line runs carefully to avoid capacity loss at the condenser.
- 120°F Ambient Ceiling: Rare in this class; most competitive units derate significantly above 105°F. This spec is the deciding factor for hot-climate outdoor installations.
- 3-Phase 208-230V Input: Standard North American commercial electrical — no transformer overhead, direct integration with typical switchgear and PDU infrastructure in enterprise data centers.
Deployment Considerations:
- At 245.4 kg (541 lbs), rigging and structural coordination are day-one planning items, not afterthoughts — get your mechanical engineer involved before this unit ships.
- The 95°F baseline rating means your full 101kW capacity is available at ASHRAE A2 conditions; model your capacity at your actual peak ambient, not the spec sheet maximum, to size redundancy correctly.
The ACCD76057 is the right condenser for rooftop split-system installations at edge data centers, manufacturing facilities, or mid-sized colocation builds in regions where peak summer ambient temperatures regularly challenge standard condenser ratings — if that matches your site conditions, this is the unit to specify.
