MAKKAH — The General Presidency for the Affairs of the Grand Mosque and the Prophet’s Mosque has activated the largest cooling system of its kind in the world, as part of preparations for the 1446 Hajj season.

The system boasts a total capacity of 155,000 tons of cooling.

The air conditioning infrastructure of the Grand Mosque relies on two main stations: Al-Shamiya Station, with a capacity of 120,000 tons, and Ajyad Station, with a capacity of 35,000 tons.

These stations cover the entire mosque complex, including all expansion areas, ensuring pilgrims experience moderate and comfortable temperatures ranging from 22°C to 24°C.

To maintain optimal air quality, the system integrates advanced purification technologies capable of removing 95% of airborne impurities.

This ensures a clean and safe environment for pilgrims, particularly during the peak summer heat.

Proactive and continuous maintenance is being conducted by the Haram Authority.

This includes the replacement of key components, securing work sites, and efficient resource management to accommodate heightened demand during Hajj.
