F250

Freeze drier

UK Manufactured
The F250 freeze dryer is a short
cycle, high-performance unit
featuring stainless steel shelves
conducting heat directly to the
product rather that radiating.
Freeze drying with conduction
does not require such high shelf
temperatures and is therefore
safer for the product and easier to
program.
The key features of this unit are:

Fast drying capabilities of between 16 and 24 hours for
250kg depending on product type.

Fully programmable automatic cycle with 19inch
touch screen HMI.

Remote access via internet and direct factory support.
2

Shelf area of 26m and a shelf spacing of 30 mm

Fast initial product freezing via conduction and blast freezing.
The F-250 is also ideal for large scale product development and smallscale production activities.
Water cooling is required for the refrigeration system and we can supply
an appropriate sized chiller if needed.
