The Yamato ULF-201CP is a 142 L (5 cu.ft) chest-style ultra-low freezer reaching −40 °C to −85 °C, built on the ULF Platinum platform with touch-screen control, cascade two-compressor refrigeration, and networked alarming. The Yamato ULF-201CP pulls product down quickly with two large hermetic compressors and holds ultra-low setpoints for long-term biological storage, while its Platinum controller adds Hi/Low alarms with email and SMS notification, USB/FTP data logging, and VNC remote access. It is a compact top-opening ultra-low freezer for clinics, research groups, and small labs that need −80 °C storage without a full upright footprint.

Application Profile
Ultra-low storage at −80 °C is where biological material is held for the long term — cell lines, purified proteins and enzymes, nucleic acids, viral stocks, reagents, and clinical specimens whose stability depends on staying deep-frozen and never cycling warm. The ULF-201CP's cascade refrigeration stages two compressors so the second only engages on demand; that design keeps system pressure low, dissipates heat efficiently through an air-cooled condenser, and extends compressor life while still delivering rapid pull-down of a product load (see cold-chain-sample-storage).
The chest format is the right pick when floor space is tight but sample security is not negotiable: top-opening cabinets hold cold better on door openings because cold air sinks and stays in the box, and a 5 cu.ft unit fits under-bench or in a small lab room while still taking 15 racks. The Platinum controller is what separates this generation from a basic ultra-low — remote email/SMS alarming, downloadable temperature logs, and VNC access mean a facility manager can prove the cold chain held overnight and respond before a warm excursion becomes a loss (see cold-storage-selection). A ½" access port supports external monitoring probes, and CO₂/LN₂ back-up is available as an option for irreplaceable inventory.
Frequently Asked Questions
What temperature range does the ULF-201CP reach? −40 °C to −85 °C, with digital touch-screen setpoint and chamber-temperature display.
How much can it store? 142 L / 5 cu.ft, with a rack capacity of 15 in a top-opening chest cabinet.
How does it alert me to a failure? The Platinum controller provides Hi/Low alarms with email and SMS notification, dry-contact alarm and power-failure relays, a battery-backed audible/visual alarm, and downloadable temperature logs via USB or FTP.
Why choose a chest (horizontal) freezer over an upright? Chest freezers retain cold better on door openings because cold air settles in the cabinet, and they suit rooms where floor space is limited but −80 °C storage is required.
Is this the Platinum model? Yes. The "P" suffix denotes the ULF Platinum series — touch-screen control, networked alarming, data logging, and VNC remote access over the standard ULF line.
Ordering & Configuration
quote-based. The ULF-201CP is a capital ultra-low freezer sold through a quote. At quote we confirm the electrical service (115 V standard, or 208/220/230 V), floor space and ventilation clearance for the 102 × 81 × 119 cm cabinet, rack configuration, and whether you need CO₂/LN₂ back-up or cold-safety gloves. Warranty terms are confirmed with the quote, and lead time is provided at quotation. Request a quote to configure the ULF-201CP for your storage program.
ULF Platinum chest ultra-low, by capacity: the ULF-201CP (142 L / 5 cu.ft) is the compact chest unit; step up to the ULF-601CP (480 L / 17 cu.ft) for larger inventories, or to the upright ULF-401UP/801UP when adjustable-shelf vertical access matters more than door-opening cold retention. All share the Platinum touch-screen controller and networked alarming.
