🧪 Superheat Diagnostic Tool

TXVs normally maintain a fixed superheat (~10-15°F).
Taken at the return grille.
Taken at the condenser coil.
Measured physically on the large copper pipe.
Read from vapor (low-side) gauge scale.

ADD REFRIGERANT

Actual superheat is too high. System is undercharged.

Tolerance is generally Target ± 3°F. Ensure system has been running for 15+ minutes before testing.

Room Volume (Cu.Ft)
2,700 - 4,050
Required Airflow (CFM)
GMP Guidelines recommend minimum airflow ranges based on operational status (at-rest vs in-operation). Values are conservative rules of thumb.

🌬️ Room Pressurization (Cascade)

Standard GMP cascade is 10-15 Pa (0.04 - 0.06 in. w.c.)
Total area of door undercuts, pass-through cracks, etc. (E.g. a 3ft door with 1/2" gap = 18 sq in).
81
Required Airflow Offset (CFM)
SUPPLY EXCESS: You must supply 81 CFM more than you return/exhaust.
Equation used: Q = 2610 × A × √ΔP. This calculates required offset to "inflate" or "deflate" the room against leakage.

Pharma & Process

💧 WFI Loop Velocity & Biofilm Preventer

Calculates exact pump LPM to maintain turbulent flow (>1.5 m/s) in sanitary tubing.

Power P = Np × ρ × n³ × D⁵. Failure to add motor margin results in burnt stators during dense fluid spikes.

❄️ Lyophilizer Energetics Calc

Calculates the immense continuous energy required to freeze-dry (sublime) biological ice into vapor.
