Quick answer: A modular operating theatre is a surgical room built from factory-made wall and ceiling panels. The laminar flow ceiling, HEPA filters, hermetic doors, control panel and hygienic air handling unit come as one system. In the UAE, a modular operating theatre must meet the DHA Health Facility Guidelines: about 20 air changes per hour of HEPA-filtered air, 18–22 °C, 20–60% humidity and positive pressure to the corridor.
Most new theatres in Dubai, Abu Dhabi and Sharjah now arrive as engineered kits. Why? Because a modular operating theatre hits the DHA numbers at commissioning, and then holds them at every revalidation.
What a modular operating theatre includes
The kit has six parts. First, the walls: 50 mm panels with a steel, stainless-steel or HPL skin, coved at every corner. Second, the ceiling, which carries the laminar flow array, the terminal H14 HEPA filters and the lights. Third, hermetically sealed sliding doors that close against a gasket. Then come the OT control panel for temperature, humidity and pressure, the low-level return grilles and the conductive floor. Finally, a dedicated hygienic air handling unit feeds the room. In short, a modular operating theatre is one product, so one supplier owns the result.
The DHA numbers a modular operating theatre must hit
DHA Health Facility Guidelines Part E set the targets for Dubai. Similarly, DOH Abu Dhabi and MOHAP build on the same ASHRAE 170 basis. An operating room needs about 20 air changes per hour, four of them fresh, through MERV 17 (H14) HEPA filters. The room then runs at 18–22 °C and 20–60% humidity. Pressure also stays positive to the corridor, and DHA recommends 10 Pa. The laminar array must also cover the table plus 305 mm on every side at 0.15–0.3 m/s. In other words, these are air numbers, so a modular operating theatre starts with them on the first drawing.
Why the panels matter as much as the air
A theatre fails inspection for two reasons: air that misses its numbers, or surfaces that nobody can clean. Modular panels solve the second problem, because sealed joints, coved corners and a wipe-proof skin remove the weak points. In addition, services run inside the wall cavity, so an engineer can move a pendant or a gas outlet later without breaking tiles. By contrast, a plastered theatre cracks within a few Gulf summers, and every crack is a cleaning failure.
How we deliver a modular operating theatre in the UAE
Agora Climate Control Systems builds the panels, the laminar module and the hygienic AHU near Mumbai, and tests each one there. Next, we ship to Jebel Ali or Khalifa Port and install on site. After that, our engineers validate the room and hand over the IQ, OQ and PQ documents for the DHA or DOH file. The programme runs 45 to 75 days from approved drawings. Because we also make the laminar airflow units and the HEPA filters, one team answers for the whole room. See also our guide to the modular OT in the UAE.
Who should specify one
Hospitals adding or replacing theatres, and day-surgery centres in Dubai Healthcare City. A modular operating theatre also suits a running hospital, since dry construction means no wet trades. So the surgical floor stays open while the new room goes up.
Frequently asked questions
What is a modular operating theatre?
A surgical room assembled from prefabricated wall and ceiling panels, with the HVAC, HEPA filtration, laminar flow ceiling, doors and controls designed as one system.
Is it the same as a modular operating room?
Yes. Operating theatre is the British and Gulf term, while operating room is the American one. So UAE hospitals that follow FGI and ASHRAE 170 usually say operating room.
How long does a modular operating theatre take?
Typically 45 to 75 days from approved drawings to validated handover, because factory work runs while the site team prepares the room.
What does DHA require?
About 20 air changes per hour of H14 HEPA-filtered air, 18–22 °C, 20–60% humidity, positive pressure to the corridor, and a laminar array that covers the table plus 305 mm on each side.
Can a modular operating theatre go into a working hospital?
Yes. Dry panel construction, no plaster or tiling, and a short site phase make it the usual way to add a theatre without closing the floor.
