Uniflair Direct Expansion InRow

Uniflair Direct Expansion InRowSchneider Electric Uniflair Direct Expansion InRow Cooling closely couples the cooling with the heat source which minimizes air mixing and provides a predictable cooling architecture. This air, water, and glycol cooling solution for closets, server rooms, and data centers improves predictability and efficiency. The Uniflair InRow targets the heat that is generated by the IT equipment by pulling the hot air directly from the hot aisle where the heat is generated. It removes the heat and supplies cool air into the cold aisle/environment, which is the source of cool air for the IT equipment.

Intelligent controls actively adjust to match the load, addressing the dynamic demands of today’s IT environments. Available in air-cooled, self-contained and fluid cooled configurations, these units meet the diverse requirements for data center cooling. IT operators looking to improve efficiency or deploy higher density equipment will benefit from the modular design of the InRow Direct Expansion products.

Uniflair air-cooled condensers support InRow cooling products to provide a complete solution for small to medium data centers. 

Uniflair Direct Expansion InRow Benefits

  • Scalable densities – Allows for higher densities to be achieved by integrating containment with room, row and rack cooling system architectures.
  • Modular design – Modular design provides scalable solutions to add cooling as demand increases.
  • Active response controls – Monitors and actively adjusts cooling capacity to ensure proper server inlet temperatures. Through the microprocessor controller, visibility into the operation and health of the unit is provided.
  • Rack Inlet Temperature Control – Reduces the risk of hot spots at the rack level
  • Predictable cooling – Placing the unit in the row of racks moves the source of cooling closer to the heat load. This eliminates air mixing and provides a predictable cooling architecture.
  • Microprocessor controller – Utilizes intelligent, active response control, and real-time monitoring. The system is controlled by a microprocessor providing high level control functionality and human interface via a four line, eighty character, alphanumeric display
  • Real-Time Capacity Monitoring – Real-time display of current and available cooling.
  • Building management system integration – Send alarms and data points allowing you to manage critical building infrastructure from a single system.
  • Easy service access – Allows for all serviceable components to be replaced/maintained by easily accessible panels/doors.
  • Row-based architecture – Captures hot exhaust air directly from the IT equipment, thereby increasing the unit’s sensible cooling capacity over traditional cooling architectures.
  • Variable speed fans – Variable speed fans reduce energy consumption during off-peak cooling periods.
 

Uniflair Direct Expansion Popular Models

The Schneider Electric InRow DX product line is in active transition in 2026 as the portfolio moves to low-global-warming-potential (low-GWP) refrigerants ahead of the EPA Technology Transitions Rule limits, which take effect January 1, 2027. Power Solutions supports customers on both sides of the transition — current-generation R32 equipment for new installations and replacements, and lifecycle services for installed R410A equipment.

Current-Generation Models — Low-GWP R32 Refrigerant

ACRD101S — InRow DX, 300mm, 11 kW, R32 refrigerant, 200-240V single-phase, standard configuration
ACRD101P — InRow DX, 300mm, 11 kW, R32 refrigerant, with reheat and electrode humidifier (P-model)
ACRD101D — InRow DX, 300mm, 48VDC input for telecom and 5G applications

These current-generation InRow DX units use R32 refrigerant (GWP 675), well below the 700 GWP threshold that applies to new HVAC installations under the EPA Technology Transitions Rule effective January 1, 2027.

Legacy Models — R410A Refrigerant (Transition Underway)

The following Uniflair InRow models use R410A refrigerant, which exceeds the new GWP threshold for new installations. Schneider Electric is withdrawing these models from the North American market on a defined timeline: the final date to place new orders is May 31, 2026, and all units must be installed, commissioned, and operational before December 31, 2026.

ACRD100 — InRow DX, 300mm, Air Cooled, 208-230V, R410A (replaced by ACRD101S/P)
ACRD200 — InRow RD, 300mm, Fluid Cooled, 208-230V, 60Hz, R410A
ACRD301S — InRow DX, 300mm, 30 kW, R410A (ACRD300 series)
ACRD600 — InRow RD, 600mm, Air Cooled, 200-240V, 50/60Hz, R410A
ACRD600P — InRow RD, 600mm, Air Cooled, 200-240V, 50/60Hz, with humidifier, R410A
ACRD601 — InRow RD, 600mm, Air Cooled, 460-480V, 60Hz, R410A
ACRD601P — InRow RD, 600mm, Air Cooled, 460-480V, 60Hz, with humidifier, R410A
ACRH301S — InRow DX, 300mm, 30 kW, R410A (ACRH300 series)
ACRH301P — InRow DX, 300mm, 30 kW, R410A, with reheat and humidifier (ACRH300 series)

Schneider Electric has confirmed additional low-GWP InRow models are rolling out through phased portfolio transitions; specific replacement products for the larger-capacity R410A units have not yet been publicly announced. Customers operating any of the affected models should plan replacement procurement against the May 31, 2026 order cutoff.
