Ensuring cleanliness in Hybrid and EV A/C servicing

While many A/C service units offer hybrid options, proper servicing of hybrid and electric vehicles requires a thorough understanding of specific requirements. Industry standards, such as SAE J 2843 H, stipulate strict limits on oil cross-contamination during refrigerant changes.

However, simply flooding the system with refrigerant, as is common practice with some service units, is insufficient. Residual oil within refrigerant lines, magnetic valves, and service hoses can lead to contamination and potentially hazardous situations, especially in high-voltage systems.

Dometic WAECO addresses this issue with a hybrid service concept that employs a dedicated flush container. This system operates under vacuum, forcing refrigerant through the system multiple times at high pressure and in alternating directions, effectively cleaning internal components. This rigorous process ensures compliance with SAE J 2099 (approved by ILK Dresden), minimizing contamination risks and ensuring optimal performance.
