● The exterior of the box is made of high-strength and high-quality galvanized cold-rolled sheet, and the surface of the box is powder-coated to ensure durability and anti-corrosion.
● The inner cavity of the box is made of high-quality low-phosphorus stainless steel (8/10 AIS1304), which is durable and easy to clean.
● The height of the stainless steel shelf bracket is adjustable, which can be installed and removed at will, which is convenient for cleaning the inner cavity, and the shelf and sample ice storage box can be freely selected.
● The insulation layer of the box is made of high-density polyurethane foamed as a whole, and the thickness of the insulation layer is 140mm, which can reduce the loss of cold energy.
● The outer cover and inner cover of the inner door of the box are of anti-impact polyurethane (30mm thick) structure. The unique sealing strip design reduces the loss of cold air and accelerates the temperature recovery.
● Heavy duty casters and adjustable height stand for easy box movement and locked position.
● Any specification of ultra-low temperature refrigerator can enter and exit the laboratory standard width door.
● The ON/OFF switch is located inside the low temperature refrigerator to prevent the device from being turned off accidentally.

Data logging and after-sales support
● Digital recorder: The integrated data recorder can realize continuous monitoring and recording, and the data can be stored for 3 months, which meets the requirements of GMP.
● Remote alarm connection point: It is used to connect the interface of the external alarm/monitoring system provided by the user, remind users in time, ensure timely troubleshooting and recovery test, and avoid losses.
● Equipped with Secure Data (SD) card slot for easy data download.
● Ethernet interface (WiFi optional), provides connection with the outside, and can monitor the alarm and parameter status of multiple connected low temperature refrigerators at most through Cryolog2 proprietary software.

alarm system
● Microcomputer control system, with 7 independent parts to monitor the normal operation of the ultra-low temperature refrigerator, even if there is a failure, the independent alarm system will issue a sound and light alarm to ensure the normal operation of the entire ultra-low temperature refrigerator without accidents.
● Abnormal sound and light alarm: power failure, high/low temperature, low battery, filter need to be cleaned, fault condition and compressor failure, etc., and sound and light alarm to remind users to ensure the safe operation of ultra-low temperature refrigerators without accidents.
● Filter cleaning alarm: A flushable filter is installed on the front left side of the box, which can be easily repaired without using tools.
● Alarm record: open box door during operation, power failure, electrical failure, filter need to be cleaned, refrigerator and ambient temperature sensor failure and condenser failure, etc.
● Backup battery: The backup battery can maintain the temperature setting value and alarm state when the power is cut off for up to 48 hours.
● Battery Status: Displays the actual battery voltage (not a percentage) to ensure that an alarm is provided, and this condition is displayed when a power outage occurs.
● Optional CO2 and Ln2 backup system, automatic switching, provides additional sample protection in case of power failure.

temperature control system
● Microcomputer temperature controller, uses multiple temperature sensors to monitor multiple parts of the inner cavity, and the microprocessor controller continuously compares to ensure that the actual temperature of all samples in the ultra-low temperature refrigerator is not higher than the set temperature of the ultra-low temperature refrigerator.
● After the power is cut off, the setting before the power cut is used when the automatic recovery operation is performed. (Temperature and alarm settings use non-volatile memory)
● Using multiple temperature sensors, temperature controller sensing and temperature alarm system The sensor control system is completely independent to ensure the safe operation of the entire ultra-low temperature refrigerator and prevent accidents.
● When a temperature sensor fails, the compressor will be locked in the working state, and sound and light alarms will be issued at the same time to ensure the safety of samples and no accidents.
● Large-screen LCD screen setting, multiple data such as alarm door opening and operating parts are displayed on one screen, and the menu-type operation interface is simple and easy to understand. (PLATILAB Next models)
● Self-diagnosis function, when the ultra-low temperature refrigerator fails, the fault information will appear on the LCD screen, and the operation fault point is clear at a glance. (PLATILAB Next models)

door control system
● Standard type (PLAILAB STD model): The door is equipped with a strong magnetic lock and a mechanical key system.
● IC card touch sensing door opening system (PLAILAB NEXT model): The door opening system is a perfect combination of IC card touch sensing technology and strong magnetic door lock, using Cold Brain technology to open the door monitoring system, only authorized personnel use IC card to open the door, this system Effectively supervise the entry and exit of test samples to ensure that samples are safely tested without accidents.

Vacuum release technology for easy reopening
● After opening the refrigerator and then closing the door, due to the entry of outside air and the excellent sealing design, a relative vacuum will be formed inside the refrigerator, so it becomes difficult to open the ultra-low temperature refrigerator again. Angelantoni effectively prevents the formation of a vacuum in the chamber by means of a heated pressure compensation valve, which facilitates the opening of the chamber door again.
