- Upright design can be stacked or placed undercounter for convenient access when space is limited
- Lowest energy consumption in its class for greater operational savings, <4 kWh/day at -80°C
- Universal power adaptation accepts electrical input from any outlet, around the world
- Optional SenseAnywhere wireless temperature logging allows for remote monitoring via cloud-based software
- Environmentally friendly design uses only 100% natural refrigerants
- Designed for ultra-low power consumption and maximal energy savings
- Virtually eliminates any need for maintenance with breakthrough Stirling free-piston engine
- Uses 100% natural refrigerants for reduced climate impact for cooling
The Stirling Ultracold SU105UE -86C Undercounter Freezer is a compact ultra-low temperature freezer that is ideal for personal storage and situations where larger volume ULT freezers might otherwise remain half empty. The SU105UE delivers full performance ultra-low storage for undercounter, benchtop or stacked installation. These undercounter freezers feature a 105L (3.7 cu. ft.) cabinet that delivers stable, uniform -20°C to -86°C storage at a fraction of the operating cost of conventional cascade refrigeration systems. The SU105UE combines the performance of a unique free-piston Stirling engine with an efficient, thin-wall, non-CFC urethane foam and vacuum insulated cabinet. This permits high-performance, ultra-low temperature storage capacity in an undercounter, benchtop, or stacked cabinet configuration.
The Stirling integral control, alarm, and monitoring system includes an intuitive graphic user interface to display operating temperature, reserve cooling capacity, status functions, and performance metrics for field troubleshooting. Secure touchpad inputs permit access to and programming for all control functions and alarm setpoints. Using 100% natural refrigerants, the Stirling Ultracold SU105UE Undercounter Freezer stores more samples in a smaller footprint than comparable models.
All of our equipment is fully tested to perform at factory specifications before being shipped.
The Stirling Ultracold SU105UE -86C Undercounter Freezer includes:
- > 1 Shelf
- > NIST Calibration and Preventative Maintenance Report
- > Power Cord
- > Operator's Manual
- > Full 180 Day Parts and Labor Warranty
