Chest Style Low Temperature Freezers 0°C To -40°C, 22 cu.ft., Manual Defrost Overview
The Chest Style Low Temperature Freezers 0°C To -40°C, 22 cu.ft., Manual Defrost (model LTF801C) from Yamato Scientific is a laboratory chest freezer delivering 22 cu.ft. (626 L) of storage across a 0°C to -40°C range. Standard equipment includes a microprocessor digital controller, dual temperature displays, and a battery-backed alarm system. LabSupplies.com supplies this unit as an authorized dealer.
Chamber walls use 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel finished in powder-coated cool gray. A single-stage refrigeration system with one hermetic compressor and an air-cooled condenser requires no liquid coolant. CFC- and HCFC-free refrigerant supports compliance-minded facilities, and manual defrost keeps the design straightforward for routine sample storage.
Electrical options span 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase. Exterior dimensions measure 98" × 36" × 43.5" with a shipping weight of 1,075 lbs. Built in the USA and UL Listed, each freezer undergoes 7-day testing and holds setpoint in ambient environments up to +30°C.
Key Features
- Digital temperature control: two displays show the set temperature and the actual chamber temperature simultaneously.
- Battery-backed alarm system: audible and visual signals on mechanical or electrical failure, with over- and under-temperature settings, a silencing switch, and a battery test switch.
- Remote alarm hook-up: a relay provides remote alarm contacts for facility monitoring systems.
- CFC- and HCFC-free refrigeration: single-stage system with one hermetic compressor and an air-cooled condenser requiring no liquid coolant.

How to Choose the Right Low-Temp Freezer
Matching a chest freezer to a lab depends on sample volume, target setpoint, site power, and floor space. Use the criteria below to confirm the LTF801C fits your workflow before ordering.
- Capacity: the 22 cu.ft. (626 L) chamber holds up to 36 racks; confirm your sample count and rack format against this footprint.
- Temperature range: a 0°C to -40°C window suits routine cold storage; verify your protocols do not require ultra-low (-80°C) temperatures.
- Control type: digital control with dual displays lets technicians read setpoint and actual chamber temperature at a glance.
- Voltage: available in 115V, 208V, and 230V at 60 Hz plus 220V at 50/60 Hz; match the model to your circuit before installation.
- Footprint: exterior dimensions of 98" × 36" × 43.5" and a 1,075 lb weight require adequate floor space and a clear delivery path.
- Safety: battery-backed audible/visual alarms and remote contacts protect samples during power or mechanical events.
