{"product_id":"nomadic-cooling-s1-helix-48v-split-air-conditioner","title":"Nomadic Cooling S1 Helix 48V DC Split Air Conditioner","description":"\u003cp\u003eThe S1 Helix is a 48V DC two-piece split air conditioner: the condenser mounts outside on a rear wall and a quiet evaporator module cools the cabin. Nomadic designed it for sleeper cabs as an electric alternative to an idling engine or APU, and the split layout also suits custom builds where a rooftop unit will not fit.\u003c\/p\u003e\u003cp\u003eThe PWM compressor is tuned for smooth ramps and a steady overnight hold, and the minimalist interior panel shows status and fault codes while the Helix app handles pre-cooling, schedules and scenes. Finish: Arctic White or Obsidian Black. Cooling figures below are Nomadic's planning averages pending certification.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e 48V DC two-piece split air conditioner (S1 Helix)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull AC (planning):\u003c\/strong\u003e ~11,132 BTU\/hr, ~948W, ~17A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eECO (planning):\u003c\/strong\u003e ~6,875 BTU\/hr, ~451W, ~8A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressor:\u003c\/strong\u003e PWM modulation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerant:\u003c\/strong\u003e R1234yf or R134a\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior condenser:\u003c\/strong\u003e 17.83 W x 23.68 H x 8.36 D in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterior evaporator:\u003c\/strong\u003e 24.26 W x 13.07 H x 7.52 D in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePass-through:\u003c\/strong\u003e 2.25 in hole, two-piece grommet included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine set:\u003c\/strong\u003e 10 ft liquid (8 mm) + 10 ft suction (12.7 mm), cut to fit, EZ Clip fittings and service valves\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year limited\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Nomadic Cooling with Nomadic's 1-year limited warranty and US-based tech support.
