The Yamato LTF-701U is an Upright (vertical, front-opening) low-temperature freezer delivering a guaranteed operating range of 0°C to -40°C (+32°F to -40°F) with 25 cu.ft. (710 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-701U 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-701U's 25 cu.ft. / 710 L working volume and 30-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 storing reagents, controls, and specimens at a validated cold setpoint; research laboratories holding samples, enzymes, and biological materials in the 0°C to -40°C band; and small laboratories using it as primary cold storage where footprint and simplicity matter. In hospital rooms and cold-chain sample storage it delivers a continuous -40°C hold, with the battery-backed alarm and remote-alarm capability providing excursion protection. The upright (vertical, front-opening) format with 4 adjustable (5 compartments) organizes inventory into discrete, browsable compartments — favoring frequent-access workflows and a smaller floor footprint than an equivalent-capacity chest.
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 50" x 37" x 79.5" external footprint before delivery.
Frequently Asked Questions
What temperature range does the LTF-701U reach? The LTF-701U guarantees an operating range of 0°C to -40°C (+32°F to -40°F), and holds its setpoint even in warm (+30°C) ambient environments.
How much storage does the LTF-701U hold? It provides 710 L (25 cu.ft.) of usable storage with a rated capacity of 30 racks, organized across 4 adjustable shelves (5 compartments) in an upright, front-opening format.
What voltages is the LTF-701U available in? Published options are 115V / 208V / 230V at 60Hz single-phase, and 220V at 50Hz or 60Hz single-phase. Specify the required voltage and plug type at order.
Does the LTF-701U use manual or automatic defrost? The LTF-701U is a manual-defrost freezer, paired with a single-stage hermetic compressor using CFC- and HCFC-free refrigerants.
Does the LTF-701U support remote alarm monitoring? Yes. Its battery-operated alarm includes over- and under-temperature settings, an alarm-silencing switch, a battery-test switch, and a relay for remote-alarm hook-up to tie into facility monitoring.
Ordering & Configuration
The LTF-701U ships as a complete, factory-tested upright-style low-temperature freezer with digital dual-display control, battery-backed alarm, remote-alarm relay, and 30-rack capacity across 4 adjustable (5 compartments).
