The Yamato LTF-801CP is a large 626 L (22 cu.ft) chest-style low-temperature freezer holding 0 °C to −40 °C, built on the LTF Platinum platform with single-stage refrigeration and touch-screen control. The Yamato LTF-801CP is engineered to guarantee its setpoint even in warm (+30 °C) rooms — every unit is factory-tested for seven days under demanding conditions — and its Platinum controller adds Hi/Low alarms with email and SMS notification, USB/FTP data logging, and VNC remote access. It consolidates a large −40 °C inventory into a single economical cabinet for institutional reagent and sample stores.

Application Profile
Not every sample needs −80 °C. When −40 °C storage scales up, the LTF-801CP consolidates a large inventory into a single economical chest rather than a bank of small freezers or an over-specified ultra-low unit that wastes energy and shortens compressor life. At 22 cu.ft with 36 rack positions, it suits institutional reagent stores, plasma and sample archives, and industrial inventories that live comfortably in the 0 to −40 °C band; because Yamato tests every LTF for seven days in a warm room, the setpoint is guaranteed even in +30 °C ambient (see cold-storage-selection).
The chest format keeps cold in the box on lid openings — important when a large box is opened frequently. The Platinum controller supplies the same monitoring stack as the ultra-low line — email/SMS alarms, downloadable temperature logs, and VNC remote access — so a high-value −40 °C store is documented and protected rather than a blind spot in the cold chain (see cold-chain-sample-storage). A ½" access port supports external probes, and a chart recorder plus CO₂/LN₂ back-up are available as options.
Frequently Asked Questions
What temperature range does the LTF-801CP hold? 0 °C to −40 °C in a 626 L / 22 cu.ft chest cabinet with a 36-rack capacity.
When should I choose this over a ULF ultra-low freezer? When −40 °C is sufficient — the LTF's single-stage system is simpler, more economical, and lower-maintenance than a cascade −80 °C freezer, and matching the freezer to the required temperature saves energy and extends compressor life.
Will it hold −40 °C in a warm room? Yes — every LTF is factory-tested for seven days under demanding conditions and its setpoint is guaranteed in warm (+30 °C) environments.
How does it alarm and log? Touch-screen control with Hi/Low alarms via email and SMS, dry-contact alarm and power-failure relays, a battery-backed alarm, and downloadable temperature logs (USB/FTP) plus VNC remote access.
Is defrost automatic? No — manual defrost, standard for laboratory low-temperature storage.
Ordering & Configuration
quote-based. The LTF-801CP is a capital low-temperature freezer sold through a quote. At quote we confirm electrical service (115 V standard, or 208/220/230 V) and branch-circuit current, floor space and ventilation clearance for the 248 × 91 × 110 cm cabinet, rack configuration, and chart-recorder or CO₂/LN₂ back-up options. Warranty terms are confirmed with the quote, and lead time is provided at quotation. Request a quote to configure the LTF-801CP for your storage program.
LTF Platinum chest low-temperature, by capacity: the LTF-801CP (626 L / 22 cu.ft) is a large consolidation chest; step down to the LTF-401CP (340 L / 12 cu.ft) for mid-size needs, or choose an upright LTF-601UP/701UP when floor footprint is tighter than access stability. For −80 °C storage, move to the ULF Platinum ultra-low line. All share the Platinum touch-screen controller and networked alarming.
