upright1-doorelectric

Product overview
LAUDA Versafreeze ultra-low temperature freezers feature an intuitive touch display, password-protected user management and optional secure monitoring via the LAUDA Cloud. They provide location-independent monitoring and control of critical values for long-term storage of biological and other sensitive materials.

Features

• Laboratory upright freezer with reliable monitoring and high-efficiency vacuum insulation for long-term storage and quality assurance
• Password-protected user management to prevent unauthorized changes to setpoints
• Interior fully made of stainless steel for compatibility with laboratory workflows
• Built-in data logger for temperature and alarm recording
• Cooling coils blown into the cabinet sides ensure rapid freezing and uniform temperature distribution
• Vacuum insulation reduces wall thickness to increase usable volume with a compact footprint
• Comfortable 4.3" touchscreen control with digital display for all safety-relevant values
• Electronic alarm system and potential-free contact for connection to on-site alarm or central control systems
• Seven inner compartments, each protected by an insulating door to limit temperature loss during access
• IIoT-ready via Ethernet interface and RS-485 for integration and remote monitoring
• Energy-saving, maintenance-free refrigeration with fully hermetic high-performance compressors
• Two standard lead-throughs (Ø 13 mm) for external control sensors (e.g. Pt100)
• Adjustable high/low temperature alarm limits and battery-backed display/alarm functions
• Use with natural, future-proof refrigerants; magnetic sealing prevents door gasket icing
