Every facility has unique air quality, humidity, and temperature requirements. We start with your application parameters and engineer a system that meets them precisely — not an oversized catalog product that wastes energy and budget.

Challenge: Maintaining ISO 14644 Class 5-8 cleanroom standards with precise temperature (20-22°C ±0.5), humidity (45% ±5% RH), and positive pressure cascade across production zones.
Our Approach: AirPure AHUs for pharmaceutical applications incorporate HEPA H14 terminal filtration, stainless steel or powder-coated aluminum interiors for GMP compliance, and redundant fan systems for continuous operation. Integrated BMS connectivity enables real-time monitoring of particle counts, differential pressure, and temperature at every zone.
Challenge: Preventing condensation, microbial growth, and cross-contamination in temperature-controlled production areas while meeting HACCP and FDA 21 CFR Part 110 requirements.
Our Approach: HACCP-compatible dehumidification systems with stainless steel construction, condensation prevention engineering, and washdown-ready components. Desiccant dehumidifiers maintain low dew points in chocolate, confectionery, and frozen food production lines where moisture directly impacts product quality.
Challenge: Maintaining server inlet temperatures of 18-27°C and 40-60% RH per ASHRAE TC 9.9 guidelines, while minimizing PUE and maximizing free cooling hours.
Our Approach: Precision air handling units with economizer-first control strategies that maximize free cooling hours. Variable airflow with EC fans, evaporative cooling stages, and hot/cold aisle containment-optimized discharge patterns. Real-time monitoring integrates with DCIM platforms for capacity planning and PUE tracking.
Challenge: Balancing occupant thermal comfort and indoor air quality with energy performance targets (ASHRAE 62.1, EN 16798) in offices, hotels, hospitals, and retail environments.
Our Approach: Fan coil units and central AHU systems with demand-controlled ventilation (DCV), CO2-based occupancy sensing, and enthalpy recovery wheels. Our modular AHU platform allows future capacity expansion without replacing the entire unit.
Choosing the right air treatment approach requires evaluating trade-offs across multiple technical and economic dimensions.
| Selection Dimension | Key Considerations | Typical Impact |
|---|---|---|
| Energy Recovery Method | Rotary wheels offer 80-85% total efficiency but carry 1-3% cross-contamination risk. Plate exchangers eliminate contamination but max out at 60-75% sensible recovery. Run-around coils suit physically separated supply/exhaust paths with 45-55% efficiency. | Energy cost difference of 20-35% between methods for the same building over a 15-year lifecycle. |
| Fan Motor Technology | EC (electronically commutated) motors achieve IE5 efficiency class and allow stepless speed control. AC induction motors (IE3/IE4) cost 30-40% less upfront. Breakeven on EC investment typically occurs at 3,000-4,000 annual operating hours. | EC motors reduce fan energy by 30-50% at part load compared to AC motors with on/off control. |
| Humidity Control Precision | Steam humidifiers deliver ±2% RH accuracy but consume 750 Wh per kg of steam. Evaporative (adiabatic) humidifiers use only fan energy but achieve ±5-8% RH and introduce water treatment requirements. Ultrasonic humidifiers sit between at ±3% RH with moderate energy use. | Operating cost difference of 3-8x between steam and adiabatic methods for equivalent moisture output. |
| Filtration Grade vs. Operating Cost | Each filter class upgrade (e.g., F7 to F9, or F9 to H13) adds 100-300 Pa pressure drop, increasing fan power. Over a filter's service life, energy cost typically exceeds the filter purchase price by 5-10x. | Specify based on ISO 16890 minimum efficiency requirements for your application, not as a general precaution. |
