Precision HVAC for surgical theaters, ICUs, cleanroom pharmacies, and diagnostic imaging — built to MINSAL and ASHRAE 170 standards for Chilean hospitals and clinics.
Clinical areas
Unidirectional laminar flow systems with HEPA H14 filtration, temperature control ±0.5°C, relative humidity 45–55% RH, and positive pressure of at least +8 Pa relative to adjacent zones. Compliant with MINSAL Res. Exenta N°283 and ASHRAE 170. We produce laminar flow canopy sizing calculations and pressure cascade diagrams for regulatory submission.
Minimum 6 fresh air changes per hour, dual-stage filtration (F7 pre-filter + H13 terminal), pressure configurable positive (immunocompromised) or negative (infectious isolation), and continuous monitoring of temperature (21–24°C) and humidity (40–60% RH). Pressure differential alarms at nursing station and central control.
Negative pressure rooms (−8 Pa) with a transitional anteroom at neutral pressure, 100% exhaust HEPA filtration (no recirculation), and real-time differential pressure alarms at the nursing station. Used for airborne-precaution patients (tuberculosis, COVID, measles). We supply and install the monitoring hardware and connect to the hospital BAS.
Sterile compounding rooms and clinical labs require laminar flow workstations, stable temperature (18–22°C), controlled humidity (<55% RH), and positive differential pressure. Design follows GMP (Good Manufacturing Practice) guidelines for sterile preparations. We provide IQ/OQ/PQ qualification documentation where required.
MRI, CT, and PET-CT rooms require strict temperature control (18–22°C) to protect magnets and detectors. We specify precision units with low acoustic noise (< 45 dB) to avoid interference with sensitive imaging equipment. Remote condenser placement prevents vibration transmission through the structure.
Dedicated refrigeration systems for mortuary chambers (2–6°C), autopsy rooms with forced exhaust at 10 air changes per hour and negative pressure for aerosol containment. Exhaust passes through HEPA terminal filtration before discharge. Design complies with MINSAL guidelines for pathology facilities.
BIM HVAC Modeling
Hospital projects require BIM coordination across architecture, structure, medical gases, electrical, and fire protection.
We work with Revit MEP and deliver IFC models (LOD 300–400) compatible with the owner's BIM platform or MINSAL/MINVU infrastructure standards.
FAQ
Surgical theaters in Chile are primarily governed by MINSAL Resolución Exenta N°283 ("Manual de Normas para Establecimientos Hospitalarios"), which sets airflow rates, cleanroom classification, differential pressure requirements, and filtration standards. Additionally, ASHRAE 170 (Ventilation of Health Care Facilities) and ISO 14644 cleanroom standards apply. For public hospital projects, the Ministerio de Salud's technical specifications for infrastructure works (MINSAL UNIH standards) also define HVAC requirements.
ISO cleanroom classification measures maximum particle concentration per cubic meter. A standard surgical theater requires ISO 5 (maximum 3,520 particles ≥0.5 μm/m³) in the operative field zone. This is achieved through unidirectional laminar airflow, HEPA H14 terminal filtration, 20–30 air changes per hour, and controlled personnel access. We provide clean room qualification protocols (IQ/OQ/PQ) and particle count measurements to certify classification after installation.
A standard surgical theater (50–80 m²) with laminar flow canopy, HEPA H14 filtration, differential pressure control, and monitoring has an installed cost of approximately UF 1,500–4,000, depending on configuration and existing civil infrastructure. Renovation projects in active hospitals are more expensive than new construction due to work-area access restrictions, protective partitions, night and weekend work, and infection-control protocols.
Yes. We offer complete BIM HVAC modeling (LOD 300–400) for healthcare projects, including coordination with architecture, structure, electrical, medical gases, and fire protection disciplines. We work with Revit MEP and deliver IFC models compatible with the owner's BIM platform. For public hospital tenders that require BIM Level 2 deliverables, we produce the required documentation in the specified formats.
Yes. We have experience in active clinical environments and follow strict protocols: sealed work zones, dust barriers, night or weekend work schedules to avoid disrupting clinical operations, and coordination with the infection control team to prevent cross-contamination during installation. All staff working in healthcare environments complete the required hospital induction and use appropriate PPE.
Yes — both sectors. We have experience with public hospitals (Servicio de Salud facilities, primary care centers) and private healthcare (clinics, medical centers, private laboratories). We manage public tender processes through Chile Compra / Mercado Público and handle private contracts directly. We prepare technical documentation in English when required by international hospital consultants or lenders funding the project.
