INDUSTRY SOLUTION
Medical & Pharmaceutical
Oulairuina develops integrated air handling equipment solutions for pharmaceutical cleanrooms, sterile production areas, active pharmaceutical ingredient workshops, laboratories and temperature-controlled medicine storage. Equipment selection coordinates cleanliness, temperature, humidity and pressure requirements with the production process, from design and configuration through technical service.
Equipment reliability
Materials and surface finishes are selected for the specified corrosion, fumigation and cleaning conditions, including hydrogen peroxide or ozone exposure where required. Smooth accessible surfaces help limit dust accumulation. Critical zones can incorporate equipment redundancy, temperature, humidity and differential-pressure monitoring with alarms. Access for leak checks, sensor calibration and planned maintenance supports the project’s GMP operating strategy and production continuity.
Different processes, independent zones
Modular sections can combine filtration, temperature and humidity treatment, pressure control and laminar-flow interfaces. Sterile A/B areas, C/D production areas, negative-pressure ingredient workshops, laboratories and cool storage each require their own design parameters. Independent zone control and production, fumigation and standby modes allow the equipment configuration to follow each process and cleanliness requirement.
Energy and installation space
Variable-frequency fans and variable-air-volume control match airflow and cooling duty to the operating load. Reduced ventilation during non-production periods is coordinated with the required cleanroom conditions. Compact equipment and coordinated duct and pipe routes help manage restricted ceiling and plant-room space. Final materials, redundancy and cleanroom performance are confirmed against the project specification.
INDUSTRY SOLUTION
Municipal Buildings
For government offices, public service halls, venues and schools, Oulairuina combines modular fresh air equipment, total energy recovery and coordinated controls. The design addresses changing occupancy, complex functional zones, outdoor-air energy loads and the maintenance demands of public buildings.
Lower outdoor-air treatment loads
Total energy recovery transfers useful energy from extract air to reduce fresh air pre-treatment demand. Variable-frequency fans can respond to CO₂, temperature and humidity sensors, adjusting airflow as occupancy changes. Working-day, holiday and occupied-hour schedules coordinate operation with the building’s ventilation requirements and energy strategy.
Comfort across different spaces
Public halls, meeting rooms, offices, corridors and equipment rooms need different airflow settings. Independently controlled supply zones, multi-stage filtration and coordinated air distribution help manage particles, odours, draughts, uneven temperatures and noise. Monitoring indoor CO₂, temperature and humidity supports changes to outdoor-air volume as visitor numbers vary.
Straightforward maintenance and supervision
Modular equipment, planned service clearances, accessible inspection openings and removable filters simplify routine work. Building monitoring interfaces can collect unit operating data and report filter differential pressure or fan faults. Maintenance guidance covers filter replacement, recovery-core cleaning and sensor calibration so property teams can plan inspections and keep the system operating consistently.
INDUSTRY SOLUTION
Rail Transit
A coordinated fresh air and terminal air handling approach serves station concourses, platforms, equipment rooms and entrances. Modular AHUs, energy recovery ventilators, dehumidification units, air curtains, unit heaters and quiet ventilation equipment are selected around each zone’s operating conditions.
Air quality and entrance protection
Energy recovery fresh air units supply outdoor air while multi-stage AHU filtration treats incoming particles. Air curtains at entrances help limit dust and outdoor-air infiltration. Extract ventilation and fresh air control are coordinated with passenger density and indoor air-quality requirements.
Temperature and humidity by zone
Modular and vertical AHUs treat concourses and platforms. Desiccant wheel dehumidification can serve moisture-sensitive equipment rooms, while heated air curtains and large-space heaters address winter entrance and high-level heating duties. Airflow and controls are coordinated separately for each function.
Energy, safety and service access
Extract-air heat recovery and zoned operation help manage energy demand. Low-noise fans and modular sections support acoustic requirements, underground delivery routes and maintenance access. Fire provisions, continuous-operation arrangements and protection of electrical equipment are specified and verified for the individual rail project.
INDUSTRY SOLUTION
Commercial Buildings
Shopping centres, offices, hotels and mixed-use developments combine spaces with very different occupancy and air-treatment loads. Oulairuina coordinates AHUs, energy recovery fresh air units, purification, dehumidification, air curtains and quiet ventilation equipment for lobbies, shops, offices and dining areas.
Fresh air and filtration
Continuous fresh air supply and appropriate airflow control help manage indoor CO₂. Multi-stage AHU filtration addresses particles and odours. Entrance air curtains reduce outdoor dust, insects and uncontrolled exchange of warm or cool air.
Independent thermal and moisture control
Modular or vertical AHUs can serve independently controlled shop, lobby, office and food-service zones. Desiccant dehumidification can be selected for humid areas, with large-space heating equipment where the building geometry requires it. The configuration follows changing people densities and seasonal loads.
Operation over the building life
Extract-air energy recovery reduces outdoor-air treatment loads. Quiet fans, accessible modular equipment and variable-air-volume operation support day-to-night, holiday and peak-season changes. Selection considers acoustic comfort, service routes and long-term operating and maintenance requirements.
INDUSTRY SOLUTION
Hotels
For business, resort and boutique hotels, Oulairuina coordinates fresh air and air handling equipment for guest rooms, lobbies, banquet halls, restaurants, back-of-house areas and swimming pools. The design balances air quality, temperature and humidity control, acoustic comfort and operating schedules.
Clean air for rooms and public areas
Energy recovery ventilation supplies guest rooms with fresh air and helps manage CO₂. AHUs with multi-stage filtration serve lobbies, restaurants and corridors. Air curtains limit outdoor heat, moisture and insects at entrance doors and reduce uncontrolled air exchange.
Different settings for different uses
Vertical and modular AHUs can treat lobbies and banquet halls, while ceiling-mounted fresh air units serve guest-room areas. Pools and laundries may require dedicated desiccant dehumidification. Independent zones allow each room type, public area and service space to follow its own conditions.
Quiet, maintainable operation
Heat recovery reuses energy from extract air. Quiet ventilation equipment and coordinated placement help protect guest rooms from noise. Modular access arrangements and time-based or zone-based operation support maintenance and changes in hotel occupancy throughout the day.
INDUSTRY SOLUTION
Large Data Centres
For server halls, power-distribution rooms and monitoring spaces, Oulairuina coordinates modular AHUs, heat recovery equipment, desiccant dehumidification, air curtains and ventilation equipment. Equipment selection considers IT operating conditions, continuous service, future expansion and the site’s energy strategy.
Filtered air and equipment protection
Multi-stage AHU filtration and ceiling-mounted fresh air treatment help limit dust and particle accumulation. Entrance air curtains can reduce moisture and contaminant infiltration. Air distribution is coordinated with the room layout and the protection requirements of precision equipment.
Controlled temperature and humidity
Air handling and heat recovery units are configured around stable room conditions. Dehumidification addresses excess moisture and condensation, while the overall humidity strategy also considers electrostatic risk. Supply routes and hot-aisle and cold-aisle arrangements are coordinated to manage cabinet hot spots.
Reliability, recovery and expansion
Redundant equipment, alarms and independent control zones can support a 24-hour operating strategy. Heat recovery and suitable outdoor free-cooling conditions may contribute to the project’s energy and PUE objectives. Modular construction allows phased capacity additions and planned maintenance. Final resilience and performance are established by the project design.
