Problem: Hospital operating theatres (OK rooms), pharmaceutical plants, and sensitive manufacturing facilities face major challenges in maintaining strict air quality and relative humidity (RH) standards. Excessive humidity in these environments can lead to bacterial growth, compromised sterility, and equipment malfunction. In Indonesia, health regulations such as PMK No. 40 of 2023 establish strict temperature and humidity criteria that healthcare facilities must fulfill.
Solution: Managing humidity and clean air in critical environments cannot be achieved using standard cooling methods alone. It requires an integrated specialized dehumidification system utilizing a Desiccant Rotor paired with multi-stage air filtration (ranging from pre-filters and bag filters to HEPA filters). This system precools the air, absorbs moisture down to precise levels via the desiccant rotor, and readjusts the supply temperature (post-cool) to meet sterile cleanroom conditions.
Recommended Unit: For cleanrooms requiring high-precision humidity control, the primary recommendation is the FRIMEC AHU Dehumidifier with Desiccant Rotor Principle. This specialized unit is engineered to achieve extreme humidity levels down to RH 1% or lower. It also incorporates a 3D sloped stainless steel drain pan to ensure smooth condensate drainage without standing water that could foster germ growth.
Filtration & Quality Certification: FRIMEC filtration systems integrate high-quality media (such as AAF) featuring options from G3/G4 and M5–F9 filters up to HEPA H13 (EN1822) certified to UL 900, meeting ASHRAE 52.2 and ISO 16890 standards. Every FRIMEC AHU is manufactured under certified quality management systems including ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018, as well as CRAA certification for cleanroom applications.
Conclusion & Application: FRIMEC AHU Dehumidifiers have proven successful across major hospital operating room projects in Indonesia, including RSAU Salamun, RSUD Sorong, RSUD Pangkal Pinang, RS Hermina PIK2, and Eka Hospital Depok. Integrating FRIMEC units guarantees compliance with PMK No. 40/2023 standards while ensuring safety and comfort during critical medical procedures.
