Healthcare Environments

Specialised ventilation (HVAC) is used in healthcare premises to provide airborne infection control in primary patient treatment and care areas such as:

Operating Departments

Critical Care Units

Isolation Rooms

Sterile Services Departments

Pharmacies

Nuclear Medicine Departments

Spectrum provide measurements and inspection reports in accordance with the healthcare standards HTM 03-01 and HBN-4. Where appropriate, Spectrum can make recommendations and adjustments to achieve the optimum performance from the HVAC system.
