Specifications & Models
Core components
Industrial-grade 4080 aluminum or SUS304 stainless steel frames, precision-engineered for stability and durability. Bolt-on, tool‑less assembly enables rapid installation, while the sealed joints prevent air leakage, ensuring the integrity of the controlled environment.
Integrated PID controllers with high‑accuracy sensors (±0.1°C / ±1% RH) maintain constant conditions. The system includes electric heaters, chilled water coils, and steam humidifiers, all managed via a touch‑screen interface with programmable setpoints and data logging.
The AHU features EC plug fans with energy‑efficient motors, variable frequency drives, and a multi‑stage filtration section. It delivers precise airflow (0.45 m/s) while maintaining positive pressure, and is designed for low noise and minimal vibration.
H14 HEPA (or U15 ULPA) filters with 99.999% efficiency at 0.1 µm, encased in anodized aluminum frames. Filter integrity is guaranteed by in‑situ DOP/PAO scanning, and the gel‑seal design prevents any bypass, ensuring ISO 5 or better air cleanliness.
Deiiang‑brand AC/EC motor FFUs provide a constant vertical airflow of 0.45 m/s. The EC motors offer stepless speed control and built‑in fault detection. FFUs are easily accessible from the ceiling grid for maintenance without disrupting the cleanroom operation.
The ceiling grid is designed to hold FFUs, lighting, and sprinklers without air bypass. Paired with smooth, non‑shedding wall panels (MGO or stainless steel), the system ensures zero leakage, supports differential pressure, and maintains the required cleanliness and humidity levels.

FAQ
Typically, Deiiang’s constant temperature and humidity cleanrooms offer ±0.5℃ temperature stability and ±3% relative humidity uniformity throughout the working zone. These cleanrooms are able to provide steady state conditions using precision sensors and variable-frequency HVAC systems. This supports sensitive processes like semiconductor lithography, precision metrology calibration, and pharmaceutical stability testing all while eliminating yield loss related to fluctuations in the environment.
Yes. Deiiang has designed its constant temperature and humidity cleanrooms in accordance with the requirements of GMP and ISO for pharmaceutical and medical device manufacturing and in line with ISO 14644 standards for cleanliness. Each cleanroom can go through full IQ/OQ/PQ validation with traceable calibration of sensors and performance reports that can be provided to answer the needs of regulatory audits and quality inspections.
No. Although there is some added energy load due to the precise control of the environment, Deiiang's zoning can help reduce energy consumption in conjunction with variable-frequency air handling units. With energy recovery systems and high-efficiency insulation panels, the energy load of an entire room can be reduced by almost 40%.
Most cleanrooms with temperature and humidity control are built using modular construction and prefabricated heating and cooling systems. This means a cleanroom of this type can be operational in 2 or 3 weeks. Civil engineering will likely not be required. The systems integrate rapidly into a workshop's power and water systems and are designed to interrupt a workshop's main production the least.
Most cleanrooms require replacement of HEPA filters every 12 to 18 months. Once a month, humidifiers and dehumidifiers need cleaning, as do temperature and humidity sensors, which require calibration every three months. Our company offers a complete system inspection, including seal and fan performance inspection and control systems logic to maintain accurate, reliable operation of our cleanrooms.
We design and construct cleanrooms based on the particular needs of our clients. These needs may encompass a range of environments and can include a low-temperature, low-humidity environment from SMT (surface mount technology) assembly and the production of lithium batteries to a high-temperature, high-humidity environment used for biotech cell culture and material aging. Naturally, we design and build a cleanroom based on the specific needs and conditions of a client's existing workshop.
