Refrigeration Module Operation

 

Under a no-load condition, the FreeZone Freeze Dry Systems can achieve a 
collector temperature of -50°C or -84°C (based on model designation) or lower 
within 30 minutes when the vacuum pump is operating, depending on ambient 
temperature and humidity.  If the collector temperature does not reach the design 
temperature 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.
