Selection worksheet
Model selection starts with batch fit—not a catalogue number.
Provide these engineering inputs so shelf area, condenser margin, loading and utility demand can be evaluated together.
Container count
Vial diameter and height, fill volume, stopper format, units per batch and loading pattern.
Cycle basis
Freezing method, primary- and secondary-drying targets, known cycle duration and endpoint method.
Facility boundary
Room classification, door orientation, technical-area access, material flow and maintenance clearances.
Automation level
Manual or automatic loading, stoppering, recipe management, audit functions and plant-system interfaces.
Project evidence
Required drawings, material records, FAT scope, calibration, training and qualification responsibilities.
Published model data
A scalable SSLY pharmaceutical platform.
Values below are published references. Final performance, utilities and certificate scope must be confirmed in the project quotation.

* No-load published values. Product temperature, drying rate and batch performance depend on the product, recipe, loading and operating conditions.
Process-critical controls
What the system must control during the cycle.
These controls connect the equipment specification to actual process risk.
Freezing
Product structure begins hereReview shelf cooling, nucleation assumptions, fill depth and the temperature margin before primary drying.
- Shelf ramp and hold control
- Product probes by agreed scope
- Uniform loading pattern
Primary drying
Balance heat input and vapour flowChamber pressure, shelf temperature, condenser capacity and product temperature must remain within the process window.
- Vacuum-control strategy
- Condenser margin
- Endpoint method
Secondary drying
Reach the moisture targetControlled heating and hold time support desorption without exceeding the product temperature limit.
- Recipe repeatability
- Trend and alarm review
- Stoppering sequence
Utilities & interfaces
The chamber is one part of a production system.
Final requirements are calculated from model, cycle and site conditions. The proposal should clearly allocate every connection and responsibility.

Actual equipment
Review the system with application and facility teams together.
A productive technical review includes formulation or process development, production, engineering, quality and procurement—not model data alone.
Send the six selection inputsFAQ
Questions buyers ask before selection.
Short answers support early evaluation; project-specific decisions remain subject to engineering confirmation.
Which SSLY model is suitable for a pilot or production project?
Selection depends on container format, units per batch, shelf area, water load, loading method, utilities and documentation scope. A model code should only follow this engineering review.
Can the system include hydraulic stoppering?
The published SSLY range includes common and hydraulic stoppering configurations. The mechanism, pressure and applicable container system must be confirmed in the technical proposal.
What temperature and vacuum values are published?
Selected published SSLY data lists a no-load shelf setting range of −50°C to +70°C and ultimate vacuum of ≤5 Pa. Product performance and cycle conditions remain project-specific.
Can the system integrate with cleanroom loading and plant utilities?
Yes. Door arrangement, technical-area access, material flow, utilities, controls and documentation can be reviewed within the project system boundary.
