Engineering‑driven ventilation for hospitals and labs

We design ventilation that actively manages contamination risk and environmental stability across clinical and research spaces. That means correct air changes per hour, proper pressure relationships, filtration levels, and temperature/humidity control—continuously and reliably.

• Isolation & infection control: Negative‑pressure AIIRs, anterooms, exhaust redundancy, pressure alarms
• Surgical & procedural: Positive‑pressure ORs, laminar flow strategies, terminal HEPA where required
• Pharmacy compounding: Pressure cascades for USP 797/800 rooms, HEPA filtration, clean supply air
• Laboratories & cleanrooms: ANSI/AIHA Z9.5 ventilation strategies, fume hood and BSC exhaust integration, clean makeup air
• Support areas: Sterile processing, imaging, NICU/PICU, and isolation suites with tailored airflow patterns

Technology we integrate

Our teams are factory‑trained by Fujitsu (Japan) and also trained at manufacturer facilities for Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). On hospital and lab projects in Rialto, we apply that training to integrate energy‑efficient climate control with robust ventilation.

• Fujitsu VRF for precise temperature and humidity control across zones
• Dedicated outside air systems (DOAS) with ERV/HRV for code‑ready ventilation and energy recovery
• High‑efficiency HEPA/ULPA filtration strategies and UV‑C options for coils and airstreams
• Demand‑controlled ventilation (DCV) and airflow tracking for stable room pressure
• BACnet integration to BMS, continuous pressure/ACH monitoring, and alarm dashboards

Our process

• Assessment & design: Load calcs, pressurization maps, ACH targets, filtration specifications, and constructability
• Permitting & coordination: Submittals, shop drawings, and coordination with facility, architect, and MEP teams
• Installation & integration: Clean installs, infection‑control protocols, and seamless controls tie‑in
• Commissioning & TAB: Airflow testing, balancing, and documentation aligned with project requirements
• Training & handoff: Staff training, O&M documentation, and monitoring setup for continuous visibility

Compliance‑minded from day one

Systems are engineered to meet applicable standards, including ASHRAE 170 for healthcare ventilation, ANSI/AIHA Z9.5 for laboratories, CDC infection control guidance, and California Title 24 energy code. For California healthcare facilities, we coordinate with your design team to address HCAI (formerly OSHPD) requirements as part of the approval pathway.

Service, maintenance, and 24/7 response

Hospitals and labs cannot afford downtime. We offer preventive maintenance, filter change programs, HEPA integrity checks in coordination with certified partners, controls tuning, and rapid emergency response to protect clinical schedules and research integrity.
