These Ultra Low Temperature (ULT) freezers series are developed and manufactured in cooperation with KW, Italy and are ideal for storage of biological, pharmaceutical, plasma and other temperature sensitive material in laboratories and blood banks.
The refrigeration system is fully sealed. It uses a cascade circuit with 2 silent, airtight compressors with a high refrigeration capacityto obtain maximum cooling reliability and performance.
Every internal shelf has Evaporation tray to guarantee high refrigeration capacity, very fast cooling (reduced pull down and recovery times) and elevated uniformity of the internal temperature.
Silent - noise at a distance of 3 meters does not exceed 55 dB(A)
Large-surface condensers with tubeless execution: Unique solution that minimizes thermal resistance
Faster recovery of set Temperature after opening the door
Triple-step seal in silicone rubber for gasket prevention against air loss
Gasket heating by means of the refrigerant pipes - the safest solution against ice formation
2 PT 100 sensors; failure of one of the sensors automatically transfers the regulation to the other, including an alarm event
Intelligent controller continues to run a timed thermo stabilization with compressor on/off times collected in case of both sensor failure
Sensor placed in the condenser senses insufficient heat exchange situations with warnings in case of condenser obstruction (chocking)
Data logger for temperature with ample storage capacity
Backlit alphanumeric 2 lines LCD display
Compensation valve permitting access to the internal compartment within a few seconds after the previous closing.
Pivoting wheels for maximum freezer maneuverability.
Password Protected security for on/off, temperature set point
Disaster recovery - the freezer continues working with average on/off times recorded before the failure
Audio Visual alarms with data logging facility - Gives details of type of alarm with date and time of occurrence
High/Low internal temperature alarm, Power failure alarm, Door open alarm, Sensor failure alarm, Condenser obstruction alarm
Kit with pivoting and fixed wheels - facilitate moving the freezer
Triple silicone gasket - for maximum safety against heat loss and minimum power consumption
Hot gas pipe - heats the triple gasket and prevents the formation of frost /ice
Insulation - Polyurethane foam with minimum thickness of 140 mm., for maximum thermal protection and minimum power consumption
Two-stage, CFC- and HCFC-free refrigeration system – Environmental friendly
Tubeless two-circuit condenser with a unique design - very high thermal efficiency
Auto-speed, low-noise axial fans - adjustable to the condensation Temperature
7 days Circular Chart Temperature recorder – for recording of internal temperature
Port for remote alarm signals - to make physical connections to external devices
Micro door switch - for open door alarms
Pressure Compensation valve - permits access to the internal compartment within a few seconds after the previous closing
Highly ergonomic closing handle - facilitates easy opening and closing of door
Evaporation tray below each compartment - for the faster cooling and the better uniformity of internal Temperature
Internal chamber in AISI 304 (standard) with rounded edges for easy cleaning and maximum hygiene
Independent Internal counter doors with 20 mm polyurethane foam - better internal Temperature stability, to minimize the opening surface
External door insulated using polyurethane foam (> 110 mm.) – for maximum thermal protection and minimum power consumption
Internal-external access holes for cabling
Data Pocket Kit includes: IR transceiver, IR receiver for PC, Cold Master management software.
The controller periodically record and stores the temperature. The data can received and transferred to PC by means of the USB port provided or through Data Pocket transceiver and the serial receiver. The Cold Master supervision software allows downloading and printing [ in graph or table format] of the temperature data. The controller enters the record into two temperature channels. The memory capacity allows making an entry every 20 minutes for approximately 4 months.
