The MVE Vario Series is the innovative and energy efficient alternative for ultra low temperature to cryogenic storage. The completely dry sample storage area will maintain a user defined temperature anywhere between -50°C and -150°C.

The MVE Vario Series eliminates the possibility of sample contamination via contact with LN2 while providing the safety margin and consistent temperature profile, even with the lid open, that is associated with LN2 based cryogenic storage.

The MVE Vario Series is able to provide all of this and more with less than 1% of the power consumption and approximately 1/10 the overall operating costs when compared to the leading mechanical freezers.

Key Points
Unparalleled Performance User defined temperature within -50°C to -150°C operating range;
Consistent temperature profile – Unaffected by lid openings – No recovery time needed L
N2 consumption, only 12 L/day at -80°C
Power consumption, only 8 W
Improved sample processing time due to rapid temperature recovery upon introduction of warm racks or samples
Safety margin (LN2 supply removed until -60°C; – 96 hours from -80°C – 216 hours from -150°C 72 hour rechargeable battery backup
Significant ambient noise reduction
Password protected controller
Alarms and Monitoring; – 4-20 mA temperature output
Dual chamber temperature sensors
Event Log contains up to 30,000 unalterable, time stamped events (approx. 10 years)
15 user defined audio/visual alarms; High temperature, lid open, and stuck valve discrete alarms
RS-485 communication for remote monitoring or control

Cost and Return on Investment
Affordable and simple preventative maintenance; – No expensive compressors to replace
Approximately 1/10 overall operating costs compared to mechanical freezers
Based on power consumption and LN2 costs
Does not include additional HVAC requirements for mechanical freezers, which will further enhance Vario ROI
Green – Environmentally Friendly Less than 1% of the power consumption compared to leading ultra‐low temperature mechanical freezers;
No additional HVAC required due to negligible to negative thermal load
No ozone depleting chlorofluorocarbon (CFC) or hydrofluorocarbon (HFC) refrigerants
Zero CO2 emissions.
