Yes, Cooline 18K units are specifically designed for Gulf conditions and use T3 tropical compressors with high-temperature refrigerant (R410a or R32). They maintain strong cooling performance even when outside temperature reaches 52–54°C. Many users in Dubai, Abu Dhabi, and Qatar run them 24/7 during summer without issues.
