Stirling Ultracold SU105UE -86C Undercounter Freezer

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.

Recertification Inspection Protocol

Inspect the display for pixel clarity and brightness, replacing any dim or dead pixels.
Test all buttons for responsiveness, resistance, and durability; replace any that don’t meet standards.
Check the door seal and lock for airtightness, replacing any compromised components.
Run diagnostics on PCB test points for voltage and current accuracy, replacing faulty components.
Verify compressor output and airflow, ensuring all internal fans function properly.
Cross-check internal temperature probe accuracy with a NIST-traceable probe, recalibrating if needed.
Inspect wiring for frays or tears, replacing compromised sections as necessary.
Test the start capacitor's capacitance and replace if it’s outside the specified range.
Replace all internal filters and thoroughly clean condenser fins for efficient heat dissipation.
Verify the alarm battery holds a full charge and replace if there is any degradation.
Operate the unit for 72 hours to confirm stable temperatures and operational consistency.
Perform a final cosmetic check, repairing or touching up surfaces as needed for a professional appearance.
