Hospitals: Air treatment for healthcare

Air treatment plays a key role in healthcare facilities: it helps reduce microbiological contamination while ensuring optimal comfort for the patients and the medical teams. Public and private hospitals, retirement homes… ETT HVAC systems both guarantee thermal well-being and meet the acoustic constraints of the hospital sector.

As the manager of an hospital centre or a rehabilitation centre, you are certainly faced with the following issues:

  • Manage the air quality within healthcare buildings: for hospital hygiene, and especially in operating theatres, air treatment plays a key part because it needs to help protect the risk area (the operating field, for instance) against any microbiological contamination, as well as ensure comfort for the surgical team and the patient. The air conditioning solutions for an hospital or a retirement home must guarantee superior air quality. ETT air conditioning units are designed to meet the requirements of hospital environments
  • Leverage the energy consumption of healthcare centres: The air filtration level of high-efficiency filters guarantees optimum air quality and reduces pressure drops as well as continuous consumption of the fans, that operate 24/7 and 365 days a year in a hospital! Careful maintenance of ETT air conditioning units helps maximise their energy performance and lifetime.
