Strict Psychrometric Control for Active Pharmaceutical Ingredients (API)
Pharmaceutical manufacturing requires absolute environmental control to prevent API degradation. Floor Mounted Air Handling Units (AHUs) in these facilities are not designed for comfort cooling; they are precision psychrometric engines. By modulating chilled water flow through deep 6-row or 8-row cooling coils, the AHU strips latent heat from the air, maintaining a strict relative humidity of 30-45% to prevent powder caking during tablet compression.
Cascading Positive Pressure Zoning
To prevent cross-contamination between batching suites, the AHU must maintain a precise cascading pressure gradient. The sterile core is heavily pressurized by the AHU's high-static centrifugal blowers, forcing air outward through airlocks. The system terminates at ceiling-mounted H14 HEPA filters, guaranteeing a Class 100 (ISO 5) particulate-free environment.
