Ultralow Freezer -86ºC/-40ºC

Product catalog summary

Technical Specifications
The ultralow freezer operates within a temperature range of -40ºC to -86ºC. It features a digital display for temperature control, positioned on the front door for easy access. The freezer is designed for high energy efficiency in sample storage and includes a PT100 probe with 0.1ºC accuracy. A 3.4" touch control panel provides a graphical temperature record.

Monitoring and Alarms
The system continuously monitors incidents with an event memory system and temperature recording. It includes both sound and visual alarms with a 48-hour battery backup, which is auto-rechargeable. Alarms are triggered by maximum/minimum temperature, probe failure, voltage failure, door open, battery empty, and filter saturation. There is a potential-free output for remote alarm connection.

Remote Control and Data Management
The freezer supports remote control via RS 485/232 with reading protocols and includes a USB storage data control system. Additional wall bushings are available for cables and pipes.

Refrigeration System
It features a double refrigeration system with one compressor per system, configured in auto cascade. In case of a system failure, the other can maintain temperatures below -70ºC.

Exterior and Interior Design
The exterior is finished in galvanized steel coated with epoxy, supported by a system with four wheels and brakes, and adjustable feet for positioning. The interior is made of stainless steel with rounded corners for easy cleaning.

Door and Isolation
The freezer has four individual interior service doors, a lock with a key, and an independent padlock. It includes a front document holder. Insulation is provided by 120 mm vacuum-injected VIP panels.

Cooling
The system uses the latest generation HC natural refrigerants.
