Chest Style Low Temperature Freezers 0°C To -40°C, 21 cu.ft., Manual Defrost Overview
The Chest Style Low Temperature Freezers 0°C To -40°C, 21 cu.ft., Manual Defrost (model LTF701C) is a Yamato Scientific laboratory freezer engineered for long-term cold storage across a 0°C to -40°C range. With 594 L (21 cu.ft.) of interior space, this chest-style unit accommodates up to 42 racks. LabSupplies.com supplies it as an authorized dealer.
Chamber walls are 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel finished in power-coated cool gray. A single-stage refrigeration system runs one hermetic compressor with an air-cooled condenser, so no liquid coolant is required. Refrigerant is CFC- and HCFC-free. Digital control drives two displays — one shows the setpoint, the other the actual chamber temperature.
Electrical options cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 91 × 36 × 49 in (231 × 91 × 124 cm), and the unit weighs 975 lb. Built in the USA, every freezer is UL Listed and undergoes seven days of full testing before shipment.
Key Features
- Dual-display digital control: microprocessor controller with two displays, showing 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, an alarm silencing switch, and a battery test switch.
- Remote alarm relay: built-in relay for hooking the freezer into a facility monitoring or remote alarm system.
- CFC- and HCFC-free refrigeration: single-stage system with one hermetic compressor and an air-cooled condenser that needs no liquid coolant.
- 42-rack interior capacity: 594 L (21 cu.ft.) chamber measuring 81 × 21.5 × 21 in, plus a 1/2" access port for probes or sampling lines.
- 7-day factory testing: every unit runs a full seven-day test, holding a constant low setpoint even in warm +30°C ambient conditions.
How to Choose the Right Low-Temp Freezer
Matching a chest freezer to your protocol means weighing storage volume, target temperature, control sophistication, and your facility's power and floor space. Use the criteria below to confirm fit .
- Capacity: total interior volume and rack count determine how many samples you can store; the LTF701C holds 594 L (21 cu.ft.) and up to 42 racks.
- Temperature range: confirm the unit reaches your required setpoint; this model operates from 0°C down to -40°C for long-term cold storage.
- Control type: digital dual-display control lets technicians verify setpoint versus actual chamber temperature at a glance, reducing logging errors.
- Voltage: match the unit to your available circuit; options span 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz.
- Footprint: chest-style units need open floor area; verify the 91 × 36 × 49 in exterior fits your room and access path.
- Safety and monitoring: battery-backed audible/visual alarms and a remote alarm relay protect samples during power or equipment failures.
