Ventilation & smoke extraction in Ajman City 

Ventilation & smoke extraction in Ajman City: local context

Ajman City covers the emirate's compact urban core along the corniche and inland districts, with residential high-rises, mid-rise apartment blocks, beach hotels and retail, much of it built since the 2000s at more affordable price points than neighbouring Sharjah and Dubai. Manolia's work in Ajman includes HVAC works for a G+6 residential building. Hotels along the beachfront add hospitality work to the mix.

• Mid-rise residential buildings typically use VRF, ducted split or air-cooled chiller systems, sized and derated for summer conditions on tight roofs.
• Corniche-side towers face salt and humidity, so outdoor equipment needs coated coils and corrosion-resistant supports.
• Etihad WE handles power and water connections, and Civil Defence (Ministry of Interior) approves fire systems, so details differ from Dubai practice.

Building types we serve in Ajman City

For malls and retail centres, the work concentrates on large-volume air handling, tenant-ready chilled water or refrigerant capacity, smoke extraction for atriums and car parks and food-court exhaust.

Scope of work

• Installation of car park ventilation with jet fans, main extract fans and CO or NO2 sensors controlling normal ventilation.
• Stair and lift lobby pressurisation fans with relief dampers or variable speed control to maintain pressure without making doors hard to open.
• Interface wiring with the fire alarm system for zone-by-zone activation and fan status feedback.
• Natural ventilation openings, automatic smoke vents and their actuators where the fire strategy relies on them, tested to open on alarm.

Systems we install

• Stair and lobby pressurisation fans
• Automatic smoke vents and actuators at roof or high level

UAE site and climate challenges

• Strong winds and sand can jam relief dampers and louvres, so these are checked during commissioning and included in periodic maintenance to ensure they open and close freely on demand.
• Basement car parks in coastal towers can see condensation on cold surfaces when hot humid air is pulled in at high rates, so supply air paths and ramp openings are reviewed to limit wet floors and corrosion of jet fans.
• Fan redundancy and secondary power arrangements, which add cost but determine how robust the smoke control system remains if one fan or one supply fails during a fire.
