The ULF-001CP is the entry-capacity model of Yamato's ULF Platinum chest (horizontal, top-opening) ultra-low freezer line — 56 L / 2 cu.ft. of validated -40°C to -85°C storage in a compact 25.25" x 25.75" x 40" cabinet that fits where floor-standing uprights will not. It pairs Yamato's 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. Top-opening chest geometry retains cold air when the lid is raised, which supports temperature recovery and sample integrity during access. It is the right pick for clinics, hospital rooms, medical clinics, and small research laboratories that need audit-grade ULT storage at the smallest available footprint.

Application Profile
Per the ULF Platinum series primary uses, the ULF-001CP serves clinics, research laboratories, small laboratories, hospital rooms, and medical clinics. Its compact chest footprint makes it well suited to:
- Cold-chain sample storage — biologics, reagents, and clinical specimens requiring sustained -80°C-class conditions.
- Small-lab and satellite storage — a validated ULT point-of-use freezer where a full-height upright is impractical.
- Redundancy / overflow — a compact secondary unit alongside larger ULT capacity for critical-sample failover.
Design Architecture
Cascade refrigeration. Two large hermetic compressors deliver quick pull-down of the product load. The system's unique low-pressure design limits heat build-up, which supports efficient operation and extended compressor life; an energy-saving low stage runs only on demand. 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 system 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.
Frequently Asked Questions
What temperature range does the ULF-001CP maintain? It holds a validated -40°C to -85°C, delivered by a cascade system with two hermetic compressors.
How much storage does the ULF-001CP provide? 56 L / 2 cu.ft. across 6 racks — the entry-capacity, smallest-footprint model in the ULF Platinum chest line.
Is this a chest or an upright freezer? Chest (horizontal, top-opening). The top-opening geometry retains cold air when the lid is raised, supporting temperature recovery during access.
What monitoring does the Platinum package include? A touch-screen controller with dual set-point/chamber display, a Hi/Low alarm with email and SMS notification, battery back-up, a viewable temperature graph, USB/FTP data logging, and VNC remote access.
What electrical service does it require? 115 / 208 / 230 V, 60 Hz, or 220 V, 50/60 Hz, single-phase — specify at quote.
