Chest Style Low Temperature Freezers 0°C To -40°C, 27 cu.ft., Manual Defrost Overview
The Chest Style Low Temperature Freezer LTF901C from Yamato Scientific is a 27 cu.ft. laboratory freezer holding a stable 0°C to -40°C range with manual defrost. Sold by LabSupplies.com, authorized dealer, this unit pairs a microprocessor digital controller with dual displays showing both setpoint and live chamber temperature for precise cold storage.
A single-stage refrigeration circuit drives one hermetic compressor against an air-cooled condenser, so no liquid coolant is required. The chamber uses 14-gauge zinc-coated galvanized steel; the exterior is 16-gauge steel finished in powder-coated cool gray. CFC- and HCFC-free refrigerant supports the 766 L interior, which accepts up to 48 racks.
Power options span 115V, 208V, and 230V at 60 Hz single-phase, plus a 220V 50/60 Hz configuration. Built in the USA and UL Listed, the freezer measures 98" × 36" × 43.5" and ships at 1,125 lbs. Every unit runs a 7-day performance test, with a constant low setpoint guaranteed in warm +30°C ambient rooms.
Key Features
- Dual digital display: microprocessor controller shows set temperature and actual chamber temperature on separate readouts.
- 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 monitoring relay: built-in relay for remote alarm hook-up plus a 1/2" access port.
- CFC- and HCFC-free refrigeration: single-stage system with one hermetic compressor and an air-cooled condenser requiring no liquid coolant.
- Validated performance: each freezer is tested for 7 days under demanding conditions and holds its low setpoint in +30°C ambient environments.
- Optional accessories: chart recorder, CO₂ and LN₂ back-up system, additional racks, and cold safety gloves.
How to Choose the Right Low-Temp Freezer
Selecting a chest low-temperature freezer comes down to matching cold-storage volume, target temperature, and site power to your workflow. Use these axes to specify the correct unit for your lab.
- Capacity: the 766 L / 27 cu.ft. chamber and 48-rack capacity determine how many samples you can store; size to current inventory plus growth.
- Temperature range: a 0°C to -40°C span suits long-term sample, reagent, and biological storage that does not require ultra-low -80°C conditions.
- Control type: microprocessor digital control with dual displays gives precise, verifiable setpoint management for audit-ready labs.
- Voltage: confirm site power matches 115V, 208V, 230V at 60 Hz or 220V 50/60 Hz before ordering.
- Footprint: verify the 98" × 36" × 43.5" exterior and 1,125 lb weight fit doorways, floors, and clearance.
- Safety and monitoring: battery-backed alarms and a remote relay protect samples during power or equipment failure.
