Nomadic S1 Helix: The Ultimate No-Idle Electric APU
The Nomadic S1 Helix is a game-changing 12V/48V split-system air conditioner designed specifically for trucks, sleeper cabs, and off-grid vans. Unlike traditional rooftop units, the S1 Helix separates the condenser from the evaporator. This "split" design allows you to mount the noisy components outside on the rear wall or chassis, leaving your interior whisper-quiet and your roof free for solar panels or extra clearance. It is the perfect engine-off (no-idle) solution for drivers who want to save fuel while staying cool through the hottest nights.
Tech Specs
Cooling Capacity: 9,600 BTU (12V) / 10,936 BTU (Helix Max)
Power Input: Available in 12V DC (Native) and 48V DC configurations.
Current Draw (12V): * ECO Mode: ~30–38A
MAX Mode: ~47–68A
Noise Level: ≤ 60 dBa (Interior unit is significantly quieter than all-in-one rooftop units).
Refrigerant: R134a (pre-charged or kit-dependent).
Operating Range: 41°F to 86°F (Setting range).
Weight: Approximately 75 lbs (Total system).
Dimensions:
Exterior Unit: 25"H x 17.6"W x 6.6"D
Interior Unit: 20.7"W x 10.2"H x 6.7"D
Key Specs & Highlights
No-Idle Operation: Run your AC entirely off your battery bank. No need to keep the engine running, saving you thousands in fuel costs and engine wear.
Helix Smart Control: Fully compatible with the Helix app for remote monitoring, scheduling, and pre-cooling from your smartphone or watch.
Stealth & Aerodynamics: By removing the bulky unit from the roof, you reduce wind drag (improving MPG) and maintain a lower vehicle profile for garage or bridge clearance.
Modular Durability: Built with powder-coated components and stainless steel hardware to withstand heavy-duty road vibrations and weather.
Eco-Mode: Intelligent logic that prioritizes battery longevity while maintaining a comfortable sleeping temperature.
Battery Bank Size: To get the most out of this unit (especially for overnight use), we recommend a minimum of 400Ah to 600Ah of Lithium (LiFePO4) batteries. This ensures you can run the AC for 8–10 hours without depleting your starter batteries.
Solar Integration: Since the S1 Helix frees up your roof, use that space to install 300W–600W of solar panels. This can offset a significant portion of the daytime cooling draw.
Professional Installation: Because this is a "split" system, it requires connecting refrigerant lines between the inside and outside units. Unless you have HVAC vacuum pumps and gauges, professional installation is highly recommended to ensure the system is leak-free and properly charged.
DC-DC Charger: Ensure your truck or van has a high-output DC-DC charger (like a Victron Orion) so that your battery bank recharges quickly while you are driving to your next destination.
