A/C service station
The fully automatic station for the carbon dioxide A/C systems of new-generation electric and hybrid vehicles.
With a safety design built for high-pressure CO₂, a 5" TFT HMI display, a ±5 g scale and automatic leak check, it makes R744 service as easy as standard A/C service.
R744 (CO₂)
Who it's for
R744 systems run at far higher pressures than R134a and R1234yf systems and cannot be serviced with standard stations. The EKM R744 is designed for safe, fully automatic service of these vehicles.
Specialist workshops that want to service new-generation vehicles with CO₂ A/C.
Service centres setting up a lane for the brand's R744 models, who need reporting and a vehicle database.
Workshops that want to stand out by servicing every refrigerant type in their area.
Key features
Circuit, tank and connections designed specifically for CO₂ systems.
Operator safety with a high-pressure protection system and precision pressure and temperature sensors.
The vehicle database and software are updated over Wi‑Fi; the service report is sent by e‑mail.
Up-to-date charge quantities for vehicles with CO₂ A/C are in the unit; select make/model and the values are filled in.
Used oil is drained automatically and new oil is added automatically to the set amount in grams.
Leak test with audible and visual warning; automatic non-condensable purge.
Refrigerant temperature is controlled during charging for a fast, stable charge.
Effectively filters acid, moisture and particles out of the refrigerant.
Service workflow
Hava tahliyesi, yağ boşaltma, vakum, kaçak testi, yağ enjeksiyonu ve gaz dolumu sırasıyla ve kullanıcı müdahalesi olmadan uygulanır. Öndeki uyarı ışığı sayesinde işlemin sürüp sürmediği uzaktan görülür.

Frequently Asked Questions
Some new-generation vehicles use CO₂ refrigerant, above all the electric and hybrid models of certain German manufacturers. The label under the bonnet lists the refrigerant type as R744.
No. R744 systems run at much higher pressures (the high-pressure side exceeds 100 bar); the connections, tank and safety design are different. These vehicles need a dedicated CO₂ station such as the EKM R744.
R744 systems use PAG EP46 (ELC‑A60) compressor oil. See the table on the Refrigerants & Oils page for oil selection.
No. The unit connects to the internet via Wi‑Fi; software and vehicle database updates are free. A unit you buy today stays up to date for years.
Recharging units carry a 2-year manufacturer's warranty. On-site service is provided across Türkiye within 24–48 hours; labour after a repair is covered by an additional 6-month warranty. Service is provided by the team that designed and built the unit. For a fault under warranty the process has four steps: notification and registration, assessment, repair, testing and delivery; details are on the technical service page. on the technical service page.
Yes. The unit is installed on site, the scales and vacuum are calibrated, and your technicians receive user training. The user manual and training videos are also available on our YouTube channel.
