No. This page is for select earlier-generation X3 Final Inventory. The product options above show the exact models, voltages, colors and conditions currently available.

X3 Helix is the current-production X3. If you're looking for the connected Helix generation rather than remaining earlier-generation inventory, use the link below.

Start with the DC electrical system that will power the air conditioner. Choose an X3 voltage that is compatible with that system, then compare the models, colors and conditions still available in that voltage.

Open Box describes product condition, not another X3 generation. Standard and Plus represent different earlier-generation X3 configurations and feature sets.

The live product selector above is the source of truth for the X3 combinations that can currently be purchased.

The earlier X3 family has been offered across 12V, 24V and 48V DC configurations. Final Inventory is limited to the exact voltage and model combinations that remain available.

X3 is a native DC rooftop air conditioner, so the selected unit needs to be matched to the DC electrical architecture of the build. The battery bank, charging system, conductors and circuit protection also need to be sized for that installation.

X3 Standard established the modern higher-capacity X3 platform with local controls and direct-DC operation.

X3 Plus built on Standard with refinements to control logic, airflow, humidity management and mechanical support.

X3 Helix adds the Helix connected-control ecosystem along with current-generation compressor-control, airflow and electrical-protection refinements.

Features and hardware vary by generation, so use the manual for the exact X3 model you purchase rather than assuming every feature applies to every version.

Open Box describes the condition of the product, not a different X3 performance level or generation.

Open Box inventory may have opened, replaced or imperfect packaging and may show minor evidence of handling or cosmetic wear. The product page provides the current condition disclosure for Open Box X3 inventory.

Warranty and return terms can differ from new inventory, so review the applicable coverage and Open Box disclosure for the exact unit before purchasing.

Yes. X3 installation documentation uses the familiar 14 × 14-inch rooftop opening.

That opening size is only one part of fitment. Before cutting the roof, confirm the exterior and interior clearances, roof structure, ceiling thickness, wiring, plumbing and mounting requirements for the exact X3 generation selected.

Do not choose wire size or circuit protection from voltage alone. The correct electrical setup depends on the exact X3 model, voltage, cable length, current requirement, voltage drop and installation.

Nomadic publishes separate X3, X3 Plus and X3 Helix Rated Power, Wire Size & Fuse Guides in the Technical Support Library. Use the guide for the exact model selected together with its installation manual.

Yes. Nomadic currently maintains X3 Standard, X3 Plus and X3 Helix documentation, X3 and shared X-Series service components, and technical support for X3 owners.

Final Inventory does not automatically mean that an X3 has no warranty. Coverage depends on the exact product, condition and warranty terms that apply to the unit purchased.

New and Open Box inventory can have different coverage and return terms. Review the current Nomadic Cooling warranty information and the condition disclosure associated with the exact X3 configuration before ordering.

Complete any required registration after purchase, and contact Nomadic before ordering if the coverage for a particular configuration is unclear.

Final Inventory is limited to the X3 units remaining in each model, voltage, color and condition combination.

Once a specific earlier-generation configuration sells through, do not assume that the same combination will return. Other X3 options may remain available, but the selection changes as individual configurations sell out.

If the X3 configuration shown above matches your electrical system, installation and build requirements, use the live selector to confirm that exact combination is still available.
