HVAC Case Study
Pakistan Air Force Hangar - Hangar cooling with Breezair

Overview

Following a series of successful Breezair installations across Army facilities in Baluchistan, the Pakistan Air Force selected Breezair’s advanced evaporative cooling technology for a newly constructed 2,230 m² aircraft hangar and multifunctional hall in Zhob. The decision was driven by Breezair’s proven performance, energy efficiency, and reliability in challenging climates.

Challenge

Zhob experiences extreme summer temperatures exceeding 44°C. While refrigerated air conditioning systems were considered, they were deemed cost-prohibitive both in terms of installation and long-term operation. The military needed an efficient, economical solution suitable for large-volume spaces.

Solution

• System Installed: 16 × Breezair TBQ 500 units for hangar cooling
• Installation Configuration: Units mounted on one side wall with exhausts on the opposite wall
• Technology Advantage: Breezair’s superior performance, durability, and robustness—already proven in previous military installations—were key factors in the decision to once again choose Seeley International’s advanced cooling technologies.

Results

Indoor Temperature Improvement: When a temperature reading was taken in April 2025, before the peak summer temperatures of up to 49°C, the internal temperature had already fallen to 23°C, compared to an ambient 32°C, a 9°C drop, achieved before summer extremes. Perfect hangar cooling success with Breezair!

Humidity Considerations: Zhob’s relatively dry climate enhances the performance of evaporative cooling.
