Refrigeration Module Operation
Under a no-load condition, the FreeZone Freeze Dry System can
achieve a collector temperature of –50°C or lower when the
vacuum pump is operating, depending on ambient temperature and
humidity. If the collector temperature does not reach –50°C within
30 minutes, then the refrigeration module is not functioning
properly.
If any repairs are required on the refrigeration module, contact
your local laboratory supply dealer. If your laboratory supply
dealer is unable to provide assistance, please call Labconco.
Repairs should only be undertaken by a competent refrigeration
technician or through an authorized Labconco service agency.
