Commercial Hospital-Grade Air Sterilization in Orange

What “Hospital‑Grade” Really Means

Hospital‑grade air sterilization goes beyond basic filtration. It is a layered approach that combines the right air changes per hour (ACH), high‑efficiency filtration (MERV 13+ and true HEPA where appropriate), UV‑C germicidal irradiation (UVGI) with validated dosage, and controlled pressurization to reduce cross‑contamination. We engineer each layer to your occupancy profile, zoning, and mechanical capacity so you receive measurable pathogen load reduction with maintainable operating costs.

Daikin‑Compatible, Turnkey Integration

We design and install sterilization solutions that integrate cleanly with Daikin VRV/VRF and air handling platforms—both new and existing. Our team evaluates coil face velocities, external static pressure, and fan capabilities to right‑size in‑duct UVGI, HEPA modules, and air purification stages without starving airflow or upsetting controls. The result: hospital‑grade performance that plays nicely with your Daikin equipment and your building automation system.

• In‑duct UV‑C modules engineered for coil irradiation and airstream treatment
• HEPA and high‑MERV upgrades with pressure drop modeling and fan curve checks
• Ozone‑free needlepoint bipolar ionization (UL 2998 listed) where suitable
• Carbon and PCO stages for VOC and odor reduction
• Controls integration for duty cycling, runtime verification, and alarms

We are not affiliated with Daikin; we engineer compatible solutions that meet your performance and compliance targets.

Industries We Serve

• Healthcare and outpatient clinics
• Life science labs and clean manufacturing
• Offices and co‑working
• Education and childcare
• Hospitality, retail, and restaurants
• Fitness and wellness facilities
• Houses of worship and community spaces

Each facility type demands a unique balance of filtration, sterilization, and ventilation. We adapt design criteria to your risk tolerance, use‑cases, and budgets—without sacrificing safety or code alignment.

Our Engineering‑First Process

• Assessment: Site survey, IAQ baseline (PM, CO2, VOC), and equipment audit
• Modeling: Load, airflow, pressure, and UV‑C dosage calculations
• Design: Layered strategy (filtration, UVGI, ionization, ventilation, controls)
• Integration: Daikin‑compatible hardware selection and control sequences
• Installation: Clean, phased work to minimize downtime
• Commissioning: Verification of airflow, ESP, UV‑C dose, and capture efficiency
• Documentation: Submittals, as‑builts, O&M, and training
• Service: Proactive maintenance and performance reporting

From concept to commissioning, you get one accountable partner who speaks engineering and delivers results.

Technologies We Deploy (Case‑by‑Case)

• True HEPA modules and MERV 13–16 upgrades with sealed frames and tested leakage
• UV‑C (254 nm) coil irradiation and in‑duct airstream UVGI with validated dose
• Upper‑room UVGI for high‑ceiling spaces with occupied‑safe design
• Ozone‑free bipolar ionization (UL 2998), applied where supported by data
• Photocatalytic oxidation (PCO) and activated carbon for VOCs and odors
• Demand‑controlled ventilation using CO2 and VOC sensing
• Pressurization control for isolation rooms, labs, and clean areas

We pair technology with measurement: pre‑ and post‑project IAQ snapshots help validate performance and guide ongoing optimization.

Compliance, Codes, and Best Practices

Our designs align with leading guidance, including ASHRAE 62.1 for ventilation, ASHRAE 170 for healthcare spaces, and ASHRAE 241 for controlling infectious aerosols, along with CDC recommendations, NFPA 90A, and California Title 24. We document assumptions, calculations, and equipment selections so you have a clear trail for reviewers and stakeholders.
