APC by Schneider Electric ACCU300D InRow DX 300MM Condensing Unit
Overview
The APC by Schneider Electric ACCU300D is a precision condensing unit engineered for InRow DX close-coupled cooling deployments. Designed for high-density data center rows and equipment enclosures where ambient cooling falls short, it pairs with a matched InRow DX evaporator unit to deliver direct-expansion cooling at the row level — keeping heat loads under control without relying solely on room-level CRAC units.
The 300MM form factor targets constrained aisle and row configurations where a standard 19-inch or wider footprint isn't practical. At a price point above $22,000, this is purpose-built commercial-grade infrastructure equipment — not a general-purpose cooling appliance. Confirm your InRow DX evaporator pairing and refrigerant circuit compatibility before ordering; mismatched condensing and evaporator units will not commission correctly.
The ACCU300D carries UL listing, which satisfies the listing requirements of most commercial building codes and insurance underwriters for mechanical cooling equipment in occupied data halls. Dual-power input (200–240V) provides flexibility for facilities with either 208V or 240V branch circuits — useful when deploying across multiple customer sites or when future-proofing against facility power upgrades.

If you are evaluating row-level versus room-level cooling strategies, compare this unit against data center power and cooling alternatives to confirm the right architecture for your heat load and floor layout.
Key Considerations Before Ordering
- Paired deployment only: The ACCU300D is a condensing unit — it requires a compatible InRow DX evaporator to form a complete DX refrigerant circuit. It does not function as a standalone cooling device.
- 200–240V dual power: Supports both 208V and 240V single-phase or three-phase input depending on configuration, giving flexibility across North American and international facility power standards.
- UL listed: Meets UL safety listing requirements for commercial mechanical cooling equipment — relevant for permit-required installations and insurance compliance in data halls.
- 300MM form factor: Optimized for narrow aisle deployments and space-constrained row configurations where standard-width cooling units cannot be accommodated.
Frequently Asked Questions
Q: What evaporator unit does the ACCU300D pair with?
A: The ACCU300D is an InRow DX condensing unit and requires a compatible APC InRow DX evaporator unit to complete the refrigerant circuit. Contact APC or a pre-sales engineer to confirm the correct evaporator pairing for your cooling load and row configuration.
Q: What voltage does the ACCU300D require?
A: The product is rated for 200–240V dual power input, accommodating both 208V and 240V facility branch circuits common in North American commercial data centers.
Q: Is the ACCU300D UL listed?
A: Yes, the ACCU300D carries UL listing as indicated in the product designation, satisfying commercial building code and underwriter requirements for mechanical cooling equipment in data environments.
Q: Can the ACCU300D be used as a standalone cooling unit?
A: No. The ACCU300D is the condensing side of a split InRow DX system. It must be paired with a compatible InRow DX evaporator unit — it cannot condition air independently.
Q: What is the form factor of the ACCU300D?
A: The ACCU300D uses a 300MM form factor, designed for close-coupled row cooling in constrained aisle configurations where wider units cannot be deployed.
The ACCU300D is a condensing unit, and the first thing I tell integrators is: do not quote this without simultaneously quoting the matched evaporator. The 300MM form factor is the spec that drives the project decision here — if your aisle can accommodate it, you get close-coupled InRow DX cooling that handles row-level heat loads far more efficiently than room-level CRAC units alone. The ACCU300D is the outdoor or remote-mounted half of that equation.
Technical Highlights:
- 200–240V Dual Power: Supporting both 208V and 240V input means this unit can be provisioned across facilities with different branch circuit standards — useful for multi-site deployments or data halls that have mixed power infrastructure from buildout phases.
- UL Listing: UL-listed mechanical cooling equipment clears the path for permit-required installations in occupied commercial data halls without additional third-party evaluation — a real schedule benefit on build-out projects.
- 300MM Form Factor: Engineered for constrained row configurations, the 300MM width opens up InRow DX deployment in aisles where a standard-width condensing unit simply won't fit, without sacrificing the close-coupled efficiency advantage.
Deployment Considerations:
- Confirm refrigerant circuit compatibility and line set distance limits with the matched InRow DX evaporator before finalizing the installation design — mismatched pairs will not commission and returns on commercial refrigeration equipment are costly.
- The weight listed in the distributor data (1.00 lb) is almost certainly a data entry placeholder — this is a commercial condensing unit priced above $22,000 and will require appropriate mechanical handling, rigging, and structural support planning on site.
The ACCU300D is the right call for high-density row cooling in space-constrained co-location buildouts or enterprise data halls where close-coupled DX cooling is the architecture — and where the aisle geometry makes a 300MM-width unit the only viable fit.
