1) Audit current LN2 cost and process load
Track monthly spend, chill times, and temperature variance by batch. This gives a baseline for evaluating alternatives.
2) Move core chilling duty to direct refrigerant
Direct refrigerant ethanol chillers can handle daily process loads while reducing consumable dependency.
3) Standardize control and monitoring
PLC/HMI visibility helps operators maintain repeatable temperature performance and reduce downtime events.
