The Yamato LTF-801C is a Chest (horizontal, top-opening) low-temperature freezer delivering a guaranteed operating range of 0°C to -40°C (+32°F to -40°F) with 22 cu.ft. (626 L) of usable storage. Every LTF freezer is fully tested for 7 days, and the constant ultra-low setpoint is guaranteed even in warm (+30°C) ambient environments. Built in the USA, the LTF-801C pairs a single-stage hermetic compressor with digital dual-display control and a battery-backed audible/visual alarm for dependable sample protection in clinics, research labs, small laboratories, hospital rooms, and medical clinics. This is capital equipment — freight-delivered and quote-based.

Application Profile
The LTF-801C's 22 cu.ft. / 626 L working volume and 36-rack capacity suit labs needing reliable -40°C storage without ULT (-80°C) cost. Per the LTF Series brochure, primary uses span clinics and medical clinics for reagent, control, and specimen storage at a validated cold setpoint; research laboratories for sample, enzyme, and biological-material storage in the 0°C to -40°C band; and small laboratories needing primary cold storage where footprint and simplicity matter. In hospital rooms and cold-chain sample storage it provides a continuous -40°C hold, with battery-backed alarm and remote-alarm capability for excursion protection.
The chest (horizontal, top-opening) format minimizes cold-air loss on door opening — cold air settles and stays in the chamber — which supports temperature stability and energy efficiency for archival or lower-access-frequency storage.
Design Architecture
Refrigeration. A single-stage refrigeration system with one hermetic compressor drives the 0°C to -40°C range using CFC- and HCFC-free refrigerants — a simpler, more serviceable mechanical package than cascade ULT systems, matched to a -40°C lowest guaranteed setpoint.
Control and monitoring. Digital control with two temperature displays shows the set temperature and the actual chamber temperature simultaneously, so operators verify both target and real conditions at a glance. The battery-operated alarm system issues an audible and visual signal on mechanical or electrical failure, provides over- and under-temperature limits, an alarm-silencing switch, and a battery-test switch. A relay for remote-alarm hook-up lets the freezer tie into facility monitoring or building alarm systems.
Construction. The interior chamber is 14-ga. zinc-coated galvanized steel; the exterior is 16-ga. steel with a powder-coated cool-gray finish for durability in demanding lab and clinical environments.
Validation and envelope. Every LTF unit is fully tested for 7 days and holds its ultra-low setpoint even in warm (+30°C) ambient environments. Confirm doorway, elevator, and floor-load clearances against the 98" x 36" x 43.5" external footprint before delivery.
Frequently Asked Questions
What temperature range does the LTF-801C reach? The LTF-801C holds a guaranteed operating range of 0°C to -40°C (+32°F to -40°F), and maintains that setpoint even in warm (+30°C) ambient environments.
