Velit 2000U - 12V/24V/48V Under-Bench Off Grid Air Conditioner

Overview

Under-bench DC air conditioner for 12V, 24V, and 48V systems. 8,000 BTU cooling with simultaneous dehumidification of up to 4 gal/day. No inverter required. Fits almost any van or RV floor plan via flexible ducting.

Key features

• Twin-cylinder rotary DC compressor — 8,000 BTU; draws 20–60A (12V), 10–33A (24V), 5–18A (48V)
• Dual function: cooling + dehumidification — removes up to 4 gal (15 L) of moisture per day
• Under-bench form factor — 23.8 × 16.2 × 11.8 in.; ducted airflow routes anywhere in the build
• No rooftop cutout required — ideal for stealth builds or floor plans with structural rooflines
• Three voltage options — 12V, 24V, or 48V DC; all priced the same

Use cases

Stealth van builds, Class B conversions, and any layout where a rooftop unit isn't preferred. The under-bench placement keeps the roofline clean and lowers the center of gravity vs. a rooftop unit. Ducted distribution means you can route airflow precisely — useful in vans with sleeping, kitchen, and work zones separated by partitions.

How is the 2000U different from a rooftop unit like the 2000R?

The 2000U mounts inside the vehicle under a bench or in a cabinet and distributes air via flexible ducting — it doesn't require a rooftop cutout. The rooftop 2000R mounts externally through the roof and delivers air via the interior trim panel. The 2000U is better for stealth builds or structural rooflines; the 2000R is better for builds where a traditional AC location on the roof is preferred.

Can it really work as a dehumidifier?

Yes. The 2000U removes up to 4 gallons (15 L) of water from the air per day as a byproduct of the cooling cycle. This is particularly useful in humid climates or coastal builds where condensation inside the van is a persistent problem. You'll need to route or drain the condensate.

Does it need an inverter?

No. The 2000U draws DC power directly from your 12V, 24V, or 48V battery bank. No inverter or shore power required.

How do I route the air distribution?

The 2000U uses flexible ducting to direct conditioned air. The duct connects to the unit's outlet and can be routed through partitions or under furniture to reach different zones in the build. This gives more flexibility than a fixed trim panel on a rooftop unit.

How much space does it require?

The unit body is 23.8 × 16.2 × 11.8 in. and weighs 50 lb. It fits under most standard van benches or in lower cabinet spaces. You'll also need clearance for the ducting outlet and condensate drainage.

What's the minimum ambient temperature for operation?

40°F. Below that, frost can form on the evaporator coil. The 2000U is a cooling-only unit — for cold weather, use a separate fuel heater.
