The FreeZone 18 Liter Freeze Dry System is a console lyophilizer for laboratory applications with large volumes of material or numerous aqueous sample batches.

Features
• Upright stainless steel collector coil capable of removing 10 liters of water in 24 hours and holding 18 liters of ice before defrosting
• 1 1/2 hp CFC-free refrigeration system to cool collector to -50° C (-58° F)
• Console cabinet that houses a rotary vane vacuum pump (pump sold separately)
• Corrosion-resistant glacier white epoxy-coated steel and brushed stainless steel exterior with blue accents
• LCD that displays system operating parameters, set up parameters and alarm messages. It may be user-configured to display vacuum in mBar, Pa or Torr and temperature in °F or °C. It also displays total number of hours of refrigeration operation and since the refrigeration was serviced and the total number of hours of vacuum pump operation and since the vacuum pump was serviced.
• Red alarm light that flashes and beeper that sounds to indicate that an abnormal system event has occurred, including: power failure, improper line voltage supply, collector temperature rise above -40° C, service vacuum pump (after 1000 hours of vacuum use), and moisture in collector. Pressing the Menu Switch displays the alarm message on the LCD
• LED vacuum and temperature "waves" for at-a-glance display of relative system vacuum and collector temperature
• Patented moisture sensor that prevents refrigeration or vacuum start up when moisture is detected in the collector chamber area
• Vacuum control valve that maintains setpoint vacuum level
• Vacuum break valve that bleeds air into the system when power to the freeze dryer or vacuum pump is shut off
• Rear-mounted RS-232 port to transmit data to a user-supplied computer
• Automatic start-up switch for collector cool down and vacuum pull down with manual override switches
• Hot gas defrost with switch
• Front-mounted, retractable, 9" collector drain
• 3" diameter port for connection of drying accessories
• Side-mounted power switch and rear-mounted electrical receptacle (for vacuum pump connection)
• 3/4" OD vacuum connection, three feet of 3/4" ID vacuum hose and two clamps
• ETL Listing (60 Hz models)

Compliance
• UL Standard 61010A-1 (60 Hz models)
• CAN/CSA C22.2 No. 1010.1 (60 Hz models)
• CE Conformity marking (220/240 volts, 50 Hz models)
