- RTA completed a major overhaul of 876
Ventilation and air conditioning units Between 14 red line metro stations, there is no service blockage. - The upgraded systems now keep the station temperature stable at 24–25 ° C, even during the hot summer months of Dubai.
- Step 3 will focus on 3
Energy efficiency upgrades And the remaining equipment aims to reduce energy use and increase stability.
Dubai roads and transport authority (RTA) has wrapped a major upgradation of ventilation and air conditioning systems on the red line and green lines of Dubai Metro. This task is part of a large strategy to ensure that passengers remain comfortable, and the metro runs smoothly, especially during the summer summer of Dubai Summer.Cooling a busy metro station is not a small task. The doors open every few minutes, causing heating out of the air. To keep the stations cool and pleasant, ventilation and air conditioning systems must work completely. 876 units were covered in the recent overhaul of RTA, including air handling units (AHUS), fan coil units (FCUS), pumps and fans. They were repaired, cleaned and replaced where they needed to restore in full work order.Importantly, all this work happened without preventing or slowing the train service. The passengers enjoyed their ride without any hindrance. This careful plan reflects RTA’s attention on combination of maintenance with smooth operation.
What upgrade covered
- Wide Reach: Upgrade is focused on two car parks with 14 stations and red lines, making it the biggest overhaul of its kind for Dubai Metro’s cooling system.
- Major components served: The project included air handling units, fan coil units, children’s water pumps, extract fans, smoke extract fans and Presorification Unit.
- Maintenance details: bearings and cooling coils, deep cleaning equipment and dynamic balance function. These steps ensure that the systems run quietly, efficiently and firmly.
- No obstruction: The work was mostly done at night and during off-pak hours so that the metro could be kept completely operational throughout the day.
- Construction on success: This phase first followed one, upgrading 261 units in 13 stations, which completely refreshed the cooling infrastructure of the metro to the entire program.
Why the cooling system for Dubai Metro matters
The extreme heat of Dubai presents a continuous challenge for public transport. Every few minutes, the train doors open, causing hot air to flow inside. Without strong ventilation and air conditioning, the stations will quickly become uncomfortable and even become unsafe for passengers.It is necessary to maintain a stable temperature between 24 and 25 ° C inside the stations. It waits and travels more comfortable and reduces the risk of heat related issues. It also helps to keep the devices in good condition, which prevents the breakdown caused by heating.This upgrade directly improves passenger experience, a main goal of the RTA strategic plan from 2024 to 2030. It also supports operating flexibility, which means that the metro is less likely to face disruption of service due to cooling failures.
What’s next: energy savings and stability
The RTA is already preparing for stage 3 of ventilation and air conditioning overhaul. This phase will target the remaining 25% fan coil units in public sectors and air handling units in the back-off-house and important areas. The test and verification work for this phase started in July 2025.In addition to repair, the purpose of the project is to introduce energy optimization. RTA is looking into variable flow technology, which can adjust the airflow depending on the demand. It reduces energy consumption and helps reduce the carbon footprint of the metro system, an important step for the stability goals of Dubai.
Team work behind the upgrade
This large-scale project reflects strong cooperation between RTA’s railway agency and Keolis-MHI, operating and maintaining the company Dubai Metro and Tram services. His joint effort ensured that the work was efficiently and safely completed with minimal impact on passengers.
