Description
Designed for secure long-term storage of pharmaceuticals and valuable samples, the LAUDA Versafreeze VF 15085 is an ultra-low temperature upright laboratory freezer combining vacuum panels, thermofoil and polyurethane insulation to minimise heat ingress. The design supports energy-efficient operation, uniform temperature distribution and fast cool-down with extended warm-up times.

Control & monitoring

• Modern touchscreen with wide setting options and digital display for all safety-relevant values
• Password-protected user management to prevent unauthorized changes to setpoints
• Optional secure monitoring via LAUDA Cloud and IIoT-ready Ethernet interface
• RS‑485 interface and potential-free alarm contact for integration with building or central monitoring systems
• Built-in data logger for temperature and alarm records; display and alarm functions maintained during power interruption (battery backup)

Design & storage features

• Upright laboratory freezer with stainless steel interior and three stainless steel drawers
• One inner compartment protected by an insulating door to reduce cold loss
• Vacuum-insulated panels to maximise usable volume with a reduced footprint
• Magnetic sealing system to prevent door/lid seals from freezing
• Two standard lead-throughs (Ø 13 mm) for control sensors (e.g. Pt100)
• Cooling coils integrated into the side walls for direct cold transfer and uniform temperature distribution
• Can be installed free-standing or built under a workbench for laboratory lines

Performance

• Energy-saving, maintenance-free refrigeration with fully hermetic high-performance compressors
• High freezing speed and uniform temperature distribution throughout the cabinet
• Adjustable high/low temperature alarm limits and electronic alarm system
• Cool-down time: from 20 °C to -86 °C in approx. 5 h; thawing time: from -86 °C to 0 °C in approx. 18 h
• Intended for long-term storage and quality assurance of organic substances and other materials

Working range

• Min. working temperature: -86 °C
• Max. working temperature: -50 °C
