Dometic CoolAir RTX 2000 from Dometic Group AB - off-grid cab cooling for pro drivers

Dometic CoolAir RTX 2000 is humming quietly on a test truck in a New Mexico rest area, its low drone cutting through the heat shimmer rising off the asphalt. The driver, Carlos Hernández, leans back in a 72 °F cab while the sun beats 100 °F outside. The unit is running fully off the truck’s batteries, no idling engine, no diesel fumes.

Battery-powered cooling for cabs

Dometic CoolAir RTX 2000 is a rooftop air conditioning unit designed specifically for truck sleepers and commercial vehicles that need cooling while parked without running the engine. It is part of Dometic’s CoolAir RTX line, which focuses on battery-powered parking coolers for professional drivers.

According to Dometic’s official product page, the RTX 2000 delivers up to approximately 2,000 W of cooling capacity and can run up to 6 hours in Eco mode from a properly sized and charged battery bank. The system is engineered for low power draw, using an inverter compressor and optimized airflow to balance comfort with battery life.

Targeting US and global truck fleets

While Dometic Group AB is headquartered in Sweden, Dometic distributes the CoolAir RTX 2000 through its North American network, positioning it for long-haul fleets and independent owner-operators in the US. Many regional dealers list the RTX 2000 for Class 8 trucks and heavy-duty commercial vehicles.

On a typical US truck, the unit mounts to the roof in place of or alongside an existing hatch, with an internal diffuser that directs cool air toward the bunk area. In practice, this means drivers can meet company and state anti-idle regulations while still maintaining overnight comfort, cutting both fuel use and localized emissions.

Specs, runtime and installation details

According to Dometic’s documentation, the RTX 2000 uses a 24 V DC electrical input and is often tied into dedicated auxiliary batteries or an electric power pack designed for parking coolers. The company highlights standby power draw and peak consumption figures to help fleet managers plan battery sizing and alternator capacity.

Real-world runtime depends heavily on ambient temperature, cab insulation, and battery health, but Dometic’s marketing materials and installer guides frequently reference the up-to-6-hour Eco mode benchmark. In hotter conditions, fleets may accept shorter runtimes in exchange for higher cooling output, especially for daytime loading stops or mandatory rest breaks.

One US-based installer who works with regional fleets described the RTX 2000’s sound profile as "a steady hum rather than the harsh roar you get from some rooftop units," noting that drivers often comment on being able to sleep without earplugs. That anecdotal feedback line up with Dometic’s focus on compressor technology and vibration damping.

Competition in no-idle cooling

Dometic is not alone in the no-idle cab cooling space; US and European competitors offer diesel-powered auxiliary units and battery-driven rooftop systems as well. However, the RTX series’ emphasis on inverter compressors and an integrated control interface gives Dometic a clear identity within this niche.

Truck OEMs and upfitters increasingly treat parking coolers as part of total driver environment packages rather than aftermarket add-ons. That trend supports Dometic’s push to get RTX units spec’d directly on new-truck build sheets or offered as dealer-installed options, making the product line part of larger fleet procurement decisions.

Dometic Group AB context and stock

Dometic Group AB has built its business around mobile living products, from RV refrigerators and awnings to marine and truck climate solutions. Parking coolers like the CoolAir RTX 2000 fit squarely into its professional-vehicle segment, which targets repeat orders from fleets and OEMs rather than one-off consumer purchases.

Shares of Dometic Group AB trade on Nasdaq Stockholm (STO/SEK) under ticker DOM, with ISIN SE0007691613, and there is no US-listed ADR. The RTX product family contributes to Dometic’s broader mobility and vehicle climate portfolio rather than driving standalone headlines in the stock.
