Initial Need:

At the time of implementing the project, Za’em Charity Hospital was fully operational, and its critical departments—including the operating rooms—were experiencing serious issues with temperature, humidity, and positive pressure control due to the poor performance of the existing ventilation system.

The primary request of the medical team and hospital management was the immediate improvement of the operating rooms’ ventilation conditions, ensuring that no interruptions occurred in medical activities during the project.

The main challenge was to design and implement a system that, in addition to maintaining cleanroom hygiene standards for medical spaces, could be installed quickly while providing stable operation and complete air filtration.

Solution:

Given the sensitivity of the space and the execution limitations within an active hospital environment, our technical team proposed the use of a 20-ton hygienic rooftop package unit.

This unit is specifically designed for medical environments and is equipped with a multi-stage filtration system (Pre-Filter, Bag Filter, and HEPA Filter), enabling full air purification to meet operating room standards.

The unit’s body is double-walled with polyurethane insulation and anti-corrosion coating, and it features low-noise centrifugal fans with inverter speed control.

The digital control system was configured to continuously and precisely regulate air temperature, humidity levels, and positive pressure within the rooms.

The installation and commissioning of the unit were carried out in phases and in full compliance with hygiene protocols to ensure that medical services continued without the slightest disruption.

Result:

With the installation and commissioning of the 20-ton hygienic rooftop package unit, the operating rooms of Za’em Hospital are now equipped with a standard, stable, and fully hygienic ventilation system.

The new system provides clean and comfortable air, maintains positive pressure in the rooms, and consequently minimizes the risk of contamination transfer.

The client expressed complete satisfaction with the unit’s quiet performance, precise control, and the significant improvement in operating room conditions.

This project represents a successful example of designing and implementing hygienic ventilation systems in active medical environments, demonstrating the engineering precision and execution capability of our team.
