The ULF-101CP is the 3 cu.ft. member of Yamato's ULF Platinum chest (horizontal, top-opening) ultra-low freezer line — 83 L of validated -40°C to -85°C storage with 8-rack capacity, a modest step up from the 56 L entry model for labs that need a bit more depth without moving to floor-standing scale. It combines cascade refrigeration (two hermetic compressors) with the full Platinum touch-screen monitoring suite: dual set-point/chamber display, Hi/Low alarm with email and SMS notification, battery back-up, viewable temperature graph, USB/FTP data logging, and VNC remote access. The top-opening chest design retains cold air during access, supporting recovery and sample integrity. It suits clinics, hospital rooms, medical clinics, and small research laboratories that need audit-grade ULT storage in a compact horizontal cabinet.

Application Profile
Per the ULF Platinum series primary uses, the ULF-101CP serves clinics, research laboratories, small laboratories, hospital rooms, and medical clinics. Typical deployments:
- Cold-chain sample storage — biologics, reagents, and clinical specimens requiring sustained -80°C-class conditions.
- Small-lab primary ULT — 83 L / 8-rack capacity for a workgroup's routine long-term sample archive.
- Redundancy / overflow — a compact secondary unit for critical-sample failover alongside larger capacity.
Design Architecture
Cascade refrigeration. Two large hermetic compressors deliver quick pull-down of the product load. The unique low-pressure design limits heat build-up for efficient operation and extended compressor life; an energy-saving low stage runs only on demand, and compressors are protected by a constant flow of refrigerant.
Heat rejection. An air-cooled condenser with two heavy-duty fans dissipates heat and requires no liquid coolant.
Resilience. An automatic timer restarts the unit after a power failure. A battery-operated alarm emits audible and visual signals on mechanical or electrical failure, with over/under-temperature settings, an alarm-silencing switch, and a relay for remote alarm hook-up. A heater harness beneath the gasket channel minimizes frost and ice build-up.
Monitoring (Platinum). The touch-screen controller displays set point and chamber temperature, logs data downloadable via USB or FTP, renders a viewable temperature graph, and supports multi-level security plus VNC remote access from a PC or smart device.
