Maintaining safety in a nuclear medicine environment - Case study
Maintaining absolute safety in nuclear medicine requires proven expertise and complete reliability—especially when handling radioisotopes and managing complex filtration systems. A major hospital in Milan turned to MANN+HUMMEL not just for filters, but for a trusted technical partner capable of delivering full-service support for its Nuclear Medicine Department.
With a comprehensive package including multi‑stage filtration, HEPA and molecular solutions, and ongoing BIBO canister maintenance, MANN+HUMMEL ensured safe, contamination‑free operation and long‑term confidence.
Key highlights:
- Trusted technical partnership beyond standard filter supply
- Multi‑stage filtration system ensuring safe handling of radioisotopes
- Professional bag‑in/bag‑out (BIBO) maintenance for secure filter replacement
- Reliable execution that resulted in a highly satisfied customer—and a direct referral
The customer: A pharmaceutical manufacturer with the highest requirements for air management
A major European facilities management company operating in more than 50 countries with annual global revenues of nearly €50 billion. The company manages facility services for a large hospital in Milan, Italy, including its Nuclear Medicine Department—the focus of this particular project
The challenge: Need for a technical filtration partner beyond standard filter supply
The facilities management company contacted MANN+HUMMEL based on the working relationship established through previous filter supply projects. They were looking for more than just filter supply for the Nuclear Medicine facility, and wanted a technical partner that could provide both product expertise and hands-on maintenance services. This included technical consultation, canister servicing, and the expertise in developing filtration systems for areas handling radioisotopes
The solution: From installation to ongoing care: a full-service filtration approach
Transitioning from a supply-only relationship to a full-service partnership, MANN+HUMMEL provided a comprehensive package that included installation and ongoing maintenance.
Each canister group was equipped with two or three filter stages, with the air handling unit (AHU) delivering around 44,000 m³/h of air. Working with the customer, we recommended, supplied and installed:
- Fine dust filters—ePM1 55% efficiency
- HEPA filters—Nanoclass Cube H13
- Molecular filters—Carboactiv Cube with activated carbon for radioisotope filtration
In addition, we also provided a canister maintenance service, which included replacing the bag-in/bag-out (BIBO) bags as required on an ongoing basis.
The result: Massive energy savings in pharmaceutical production
The multi-stage filtration system successfully maintained the required air quality and safety standards for the Nuclear Medicine Department.
The combination of pre-filtration, HEPA filtration, and activated carbon molecular filtration provided effective containment of radioisotopes, while the bag-in/bag-out maintenance service ensured safe filter replacement without environmental contamination.
The customer reported satisfaction with both the solution design and service execution. So much so, that the customer has already asked MANN+HUMMEL to manage the monitoring of nuclear medicine in the hospital for next year too.
