Mosque HVAC in Al Mahjar

At the survey we set diffuser angles, air velocity and duct routing so cold air travels to the last row. After installation we measure the temperature difference between the front and back rows and adjust each diffuser's balance until that difference is as small as the space allows.

Yes. We agree a phased schedule with mosque management in advance and divide the work into sessions between prayers. Before each call to prayer we lift tools, cover any temporary openings and return the hall to a usable state, then resume afterwards.

We fabricate ducts in our own workshop from G90 galvanised sheet, round or rectangular as the design requires. We use Armaflex and Kimmco insulation and Foster sealants to limit heat gain and keep sound transmission through the ductwork as low as possible.

Yes. The controls on Carrier, YORK, General, Midea, Gree and Smart Gold units support scheduled start and stop times. At the survey we confirm the scheduling options for the chosen units and programme the timings at handover, so the hall is already cool when worshippers arrive.

Yes, if the system is designed in zones. We divide the hall into sections, each with its own unit or closable outlets, so you run the front rows alone when few people attend and the whole hall for Friday prayer and occasions, cutting power use without affecting worshippers.

We design distribution ducts from the central unit spreading horizontally under the ceiling or floors, with vents positioned across the rows to prevent cold spots concentrating in one area.

Capacity depends on the prayer hall's size, typical attendance, ceiling height and sun exposure; we assess the site before recommending the right unit size.

We select low-noise central units and line distribution ducts with acoustic insulation to dampen sound before air exits the vents.

Running ducts under existing marble is difficult, but we can route them above the ceiling or through side-room walls depending on the building's structure.
