How to read a Hull Freeze Dryer Model Number

Example: 650 F X S 1100 - SS 25C

The 650 indicates the usable shelf product area in square feet. We have made freeze dryers from 2 square feet (.19 m2) to 1080 square feet (100 m2).

The F refers to a Freeze Dryer as opposed to a shelf dryer. We also make shelf dryers.

The X indicates a unit with an external ice condenser vessel. We make both internal and external ice condensing systems.

The S refers to a unit with shelf stoppering capability. We make units with fixed shelves as well.

The 1100 indicates the lyophilizer's ice holding capacity as liters of water. We have made condensing systems with capacities from 5 liters to 1200 liters.

The SS indicates stainless steel construction of all product contact and cleanroom surfaces.

The 25C indicates an ASME Code Certified pressure rating of 25 lbf/sq.inch gauge. Hull designs and fabricates its own vessels in-house and is certified to the American Society of Mechanical Engineers Section VIII Division 1 requirements for Unfired Pressure Vessels. Our standards are 20 lbf/sq.inch, 25 lbf/sq.inch, and 30 lbf/sq.inch, dependent upon the customer's Steam In Place requirements.
