Nuclear industry safety ventilation and pressure control diagram

Professional solutions for negative pressure gradients and safe exhaust in nuclear facilities.

HEXASci-Set provides products and solutions for high-safety ventilation control in nuclear power plants and research facilities, maintaining negative pressure gradients, directing radioactive aerosols and hazardous gases through designed exhaust paths, and supporting long-term reliable operation with lower lifecycle cost and optimized energy use.

Core of Nuclear Industry HVAC Ventilation Control

Effective airflow control establishes proper negative pressure gradients, ensuring airflow moves from low-contamination green zones toward high-contamination red zones while meeting overall air-change requirements.

Ventilation is vital to safe nuclear facility operation. Project experience shows that pressure-independent airflow terminals can effectively maintain airflow balance and adaptive negative pressure gradients.

Our R&D and delivery teams have extensive experience with pressure-independent airflow equipment in domestic nuclear facility projects, providing full technical support from system design and solution selection to commissioning and handover.

Typical Application Solutions

Nuclear Facility Pressure Control Solution

Airflow Balance Control Logic for Hot Cells and Hot Cell Rooms

Hot cells are commonly used in radioactive facilities or radiopharmaceutical workshops. Radioactive aerosols and particles generated inside must be filtered and exhausted through effective ventilation while maintaining negative pressure. Hot cells usually rely on negative pressure for natural makeup air, with HEPA filters at inlet and outlet. This high-airtightness negative pressure application places very high demands on dampers and control logic. Based on project experience, HEXASci-Set developed a dedicated controller for adaptive hot cell negative pressure and room pressure control.

Hybrid Airflow Offset and Pressure Control Solution for Nuclear Facilities

Basic Logic for Nuclear Facility Negative Pressure Control

Negative pressure control in nuclear facilities differs from conventional cleanroom pressure control. It typically uses variable supply and constant exhaust; stable exhaust is critical to filter and discharge radioactive aerosols or particles. Negative pressure is achieved by varying supply airflow while requiring each area to operate stably without mutual interference.
