Hospital Purification Ventilation Solution for COVID-19 Emergency Facilities

Protecting Doctors, Nurses and Patients

Since the 2020 COVID-19 outbreak, Holtop has designed, manufactured and installed fresh-air purification equipment for Xiaotangshan Hospital and seven other emergency hospital projects, providing supply, installation and support services. Holtop's purification ventilation delivers clean air to healthcare workers and patients, reduces virus-transmission rates, and ensures safe, filtered exhaust discharge.

Engineering for Emergency Medical Facilities

Holtop's medical ventilation follows rigorous design principles: strict clean/restricted/isolated zoning with buffer rooms; controlled negative-pressure gradients (no less than 5 Pa) directing airflow from clean to polluted areas; and directional supply/exhaust placement in negative-pressure isolation wards. Independent DX air-cooled heat-pump units regulate supply-air temperature, with auxiliary electric heating for cold climates.

Multi-Stage Filtration & Heat Recovery

Holtop's purification scheme combines G4 + F7 + H10 tertiary filtration with UVC and photocatalyst filters to neutralize germs, plus H13 high-efficiency supply outlets in the cleanest rooms. For new hospital construction, an independent ethylene-glycol heat-recovery system reduces the fresh-air treatment load — achieving energy savings without compromising safety. Holtop has converted experience from 100+ hospitals, including 301 Hospital and Xiehe Hospital, into proven, practical designs.

Asia's Largest Purification Equipment Base

Holtop operates one of Asia's largest fresh-air purification equipment production bases, supported by more than 30 sales and service agencies providing 24-hour, 360-degree technical and after-sales support — ensuring medical ventilation systems run accurately and reliably.
