Nomadic X2 Helix 12V/48V DC Rooftop Air Conditioner - Compact
Meet the X2 Helix, a super compact, 12V/48V DC rooftop air conditioning for vans, RVs, and other small spaces.
All X2 Helix models bought from Orion now include the Premium Dual-Layer Foam Gasket. Required for peak performance.
The X2 Helix is a low-profile, battery-friendly rooftop AC built to save roof space and battery while keeping comfort steady. Control it from your phone, tablet, or watch; hold target temps with intelligent PWM modulation; and clear cabin moisture with High Humidity mode. Choose 12V or 48V and a Black or White shroud. It drops into the industry-standard 14×14 opening and is backed by US-based support. The 48V model is compatible with Ecoflow Power Kits via this 48v AC Cable, allowing direct operation from a 48V battery alongside a typical 12V/24V distribution panel.
Built on proven X-Series fundamentals, X2 Helix uses precise PWM compressor control for steady comfort with lower battery impact, spring-bushed compressor mounts to reduce vibration and noise, and a bright, high-contrast LCD with tactile buttons for glove-friendly control at the unit. Installation stays straightforward with a standard 14×14 roof opening.
Helix Highlights
- App and remote control: pre-cool, create scenes and schedules, and monitor from anywhere on phone, tablet, or watch.
- Smarter PWM cooling: smooth ramps, minimal overshoot, and steady temperature hold for longer runtimes and less battery stress.
- High Humidity mode: accelerates moisture removal after showers, coastal drives, or hot, sticky days.
- RV-C ready (optional): with the Helix AC Controller, the unit can publish status and accept commands on multiplex coach networks.
- Durable construction: sealed back plate shields electronics; automotive-grade water-resistant connectors; stainless hardware for corrosion resistance.
- Smaller footprint: compact 22.5″ × 28″ / shroud height ~6.9″ preserves roof real estate and headroom.
- Modern refrigerant: R1234yf (low-GWP, A2L).
- Peace of mind: 1-year limited warranty with US-based support.
What’s Included & Options
Choose your Voltage (12V or 48V), Color (Black or White), and Package:
- AC Only:
-
- X2 Helix rooftop unit
- Foam gasket for standard 14×14 roof opening
- Premium Dual-Layer Foam Gasket
- Crossbars with mounting hardware
- Flush-mount metal interior faceplate
- Faceplate screws (black)
- M8 mounting studs, nuts, flat washers, lock washers
- Remote control
- Leveling strip
- Foam air separator
- Condensation drain port
- Control panel + wire harness
- Full-size 14×14 cutout template (1:1 scale)
- AC + DIY Install Kit (Optional Upgrade): everything above plus an Orion DIY kit for a clean, self-install, includes:
-
- 15 ft power harness (2 AWG for 12V, 8 AWG for 48V; butt connector required; Anderson connectors are no longer recommended)
- Adhesive for the foam gasket
- Thermo tape for plenum sealing (foil tape not recommended)
- Threadlocker and heat-shrink
- Internal support trim ring
- Extra hardware and zip ties
Install Tips for Best Results
Dry-fit first, use the leveling strip to keep the unit horizontal, and seal the plenum with foam tape to prevent air mixing. For humid climates, route 1/2″ drain tubes with in-line check valves or use the included drain snorkels so condensation exits cleanly.
💡 Condensation & High Humidity Tips
On newer controllers, High Humidity Mode automatically lowers fan speed every ~20 minutes to help the system drain on humid days. To toggle via remote, press T-V-V-V and look for the blue droplet icon. Keep drain ports clear/filtered, avoid foil tape (use heat-resistant foam tape), and make sure the unit sits level on the gasket. These steps improve drainage and reduce interior drip risk.

- Standard 14×14-inch roof opening.
- Suited for camper vans, RVs, overland rigs, and off-grid builds.
Install, Fit & Downloads
- Fit: 14×14 roof opening; compact exterior footprint 22.5″ × 28″; low height ~6.9″.
- Basic install sequence: Prep and dry-fit → seat gasket and place unit → install leveling strip if needed → secure crossbars/hardware in a criss-cross pattern to 3.7 ft-lbs → install air separator and faceplate → connect DC and harness → commission and verify airflow/hold.
- Condensation: Use drain snorkels or 1/2″ tubes with check valves; keep outlets clear and angled off the roof plane.

Tips: dry-fit before sealing; plan wire routing; evenly compress the gasket; seal plenums with foam tape; set a “Quiet Night” scene in Helix for low-RPM hold while sleeping.
FAQ (Frequently Asked Questions) — click to expand
1.What’s different about the X2 Helix vs. older models?
X2 Helix adds app/remote control through the Helix ecosystem, refined PWM control logic for smoother ramps and steadier temp hold, High Humidity mode, and sealed, service-friendly connections, all while keeping the compact X2 footprint.
2.Can X2 Helix run from batteries only?
Yes. It’s a DC rooftop unit that runs directly from 12V or 48V battery systems without an inverter, generator, or shore power. Many users pair it with solar and lithium storage for off-grid stays. The 48V model is compatible with Ecoflow Power Kits via a custom 48v cable, allowing direct operation from a 48V battery alongside a typical 12V/24V distribution panel.
3.How do I choose between 12V and 48V?
Match your house battery voltage. 12V integrates with common van/RV banks; 48V pairs best with larger systems and reduces current on longer cable runs.
4.Will it fit my roof opening?
Yes. X2 Helix is designed for the standard 14″ × 14″ opening used on most vans and RVs.
5.What does the Helix app control?
Start/stop, set temperature, fan/compressor behavior, scheduling and scenes, High Humidity mode, display and chime, and basic diagnostics like coil temperature and voltage.
6.What’s the difference between AC Only and AC + DIY Install Kit?
AC Only includes the rooftop unit, faceplate, controls, and mounting hardware. The DIY Kit adds wiring, adhesive, trim ring, and accessories to streamline a clean self-install. See the lists above.
7.Does X2 Helix support RV-C / multiplex control?
Yes. With the optional Helix AC Controller, X2 Helix can publish AC status and accept commands on standard RV-C networks, enabling coach-wide UIs while still operating standalone from local controls.
8.What’s the warranty?
One-year limited warranty with US-based support.
