Integrated Cooling System - R290
The secondary loop-based cooling system is designed to enable the usage of R290 (propane) as refrigerant. It works as a compact interface to the refrigerant unit, reduces system costs as well as assembly efforts and provides high flexibility based on the market requirements.

Highlights
- Enables R290 (propane) usage
- Cost effective system
- Compact design
Advantages
- Secondary loop system to car cabin and ambient
- Reduced system cost and assembly
- Easy adjustability to or from all refrigerants
- Low leakage valves empower indirect system effectiveness
- Interface to R290 refrigerant unit
