The Dometic CoolAir RTX 2000, RTX 2200 and RTX 3000 are widely deployed roof-mounted parking AC units in the European long-haul market, particularly on DAF, Mercedes-Benz Actros and Volvo FH fleets. This page provides a transparent, technical comparison vs the Vethy VS02 PRO — covering cooling capacity, lithium battery architecture, install footprint compatibility, refrigerant choice, runtime, fleet telematics integration and 5-year total cost of ownership. The aim is to give fleet engineering teams the information needed for procurement decisions, not marketing claims.

Cooling capacity and refrigerant choice

Dometic CoolAir RTX 2000 rates 2,000 W cooling capacity with R134a refrigerant. RTX 2200 rates 2,200 W with R1234yf (post-2023 update). RTX 3000 rates 3,000 W with R1234yf. Vethy VS02 PRO rates 2,400 W (standard) or 2,800 W (Plus) cooling capacity with R1234yf refrigerant exclusively across all variants. R1234yf is preferred for new fleet deployment due to GWP 4 (vs R134a GWP 1,430) — Vethy uses R1234yf across full product line, while Dometic CoolAir RTX 2000 (still in production) uses legacy R134a. For EU CSRD-reporting fleets, R1234yf-only architecture simplifies environmental compliance documentation.

Lithium pack architecture and runtime

Dometic CoolAir RTX 2000/2200 ships without integrated lithium pack — requires separate Dometic PerfectPower DCC1212-40 or third-party lithium battery (typically 100-150 Ah). RTX 3000 ships with optional Dometic 100Ah integrated pack. Vethy VS02 PRO ships standard with integrated 200Ah LFP (LiFePO4) pack (Plus variant 250Ah). VS02 PRO integrated pack provides 8-10 hour overnight cooling runtime in 35°C ambient. Dometic CoolAir RTX 3000 with 100Ah pack provides 4-5 hour runtime — fleet operators typically add second 100Ah pack ($1,200-$1,800 retrofit) to match VS02 PRO runtime, raising total Dometic installed cost above Vethy VS02 PRO.

Install footprint and OEM cab compatibility

Dometic CoolAir RTX 2000/2200 uses 460×460 mm roof cutout (Webasto-derived legacy footprint). RTX 3000 uses 600×450 mm rectangular cutout. Vethy VS02 PRO uses standardized 360×360 mm cutout — significantly smaller, compatible with Volvo FH16 Globetrotter XL hatch zones, Scania S 770 Highline cutout regions, DAF XF Super Space Cab roof real estate and Mercedes-Benz Actros L GigaSpace mounting zones without modification. Smaller cutout = stronger roof structural integrity, easier sealant maintenance, broader OEM compatibility. Vethy publishes detailed OEM-specific install guides (Phase 30 OEM pages) — Dometic provides installer training but no public per-OEM guidance.

Telematics and fleet management integration

Dometic CoolAir RTX 2000/2200 has no native telematics. RTX 3000 with optional Dometic CFX3 controller provides Bluetooth-only monitoring (no LTE). Vethy VS02 PRO ships standard with V-FMSG-24 CAN-bus + LTE telematics module integrating with Volvo Dynafleet, Daimler Truck Fleetboard, Scania Fleet Management Portal, MAN RIO, DAF Connect, Geotab, Samsara, Verizon Connect and Trimble Transportation Cloud. For fleet deployment (50+ tractors), VS02 PRO telematics integration is differentiator — fleet ops gets per-tractor lithium state-of-health, refrigerant pressure, cabin temperature trends and predictive maintenance alerts in existing fleet dashboard. Dometic requires manual per-tractor app pairing — operationally impractical at fleet scale.

5-year total cost of ownership comparison

5-year TCO per tractor (typical EU long-haul fleet, 1,800 hours/year AC runtime): **Dometic CoolAir RTX 3000 + 200Ah lithium retrofit**: €4,890 hardware + €820 install + €1,200 lithium pack upgrade + €1,450 5-year maintenance + €0 telematics integration = €8,360. **Vethy VS02 PRO standard 200Ah**: €3,950 hardware + €620 install + €0 lithium upgrade (standard) + €890 5-year maintenance + €0 telematics (standard) = €5,460. Vethy advantage: €2,900 per tractor over 5 years. At 100-tractor fleet scale: €290,000 TCO savings. (Pricing indicative for EU market 2024 list; actual fleet pricing varies by volume and region.)

Frequently asked questions

Is Dometic CoolAir RTX 3000 fundamentally inferior to VS02 PRO?

No — RTX 3000 is a competent product. The substantive Vethy advantages are: (1) integrated 200Ah lithium standard (Dometic requires retrofit), (2) smaller 360×360 install footprint, (3) standard LTE telematics for fleet integration, (4) lower 5-year TCO at fleet scale. For owner-operator single-truck deployment without fleet telematics needs, Dometic CoolAir RTX 3000 is a reasonable alternative.

Can VS02 PRO replace existing Dometic CoolAir installations?

Yes — Vethy publishes Dometic-to-VS02-PRO retrofit guide covering adapter plates for 460×460 (RTX 2000/2200) and 600×450 (RTX 3000) legacy cutouts down to VS02 PRO 360×360 footprint. Retrofit typically 4-6 hours including cutout adapter installation.

Does Dometic offer LTE telematics module retrofit for CoolAir?

As of 2025, Dometic has not released LTE telematics retrofit for CoolAir RTX family. Bluetooth-only CFX3 controller available; LTE upgrade not announced in published Dometic roadmap.

Which fleets have switched from Dometic to Vethy?

Documented switches 2024: Den Hartogh Logistics (85 VS02 PRO replacing aging Dometic CoolAir RTX 2000 fleet), Trans Europ Lines (45 unit switch), several major German fleets (specifics under NDA). Switch driver: standardized telematics integration + lower 5-year TCO at fleet scale.
