Chest Style Low Temperature Freezers 0°C To -40°C, 9 cu.ft., Manual Defrost Overview
The Chest Style Low Temperature Freezer LTF301C from Yamato Scientific is a 9 cu.ft. laboratory chest freezer holding a 0°C to -40°C range with manual defrost. Sold by LabSupplies.com as an authorized dealer, this unit ships with a microprocessor digital controller, audible and visual alarms, remote alarm contacts, alarm battery back-up, and a 1/2" access port.
Construction pairs a 14-ga. zinc-coated galvanized steel chamber with a 16-ga. steel exterior finished in powder-coated cool gray. Cooling runs on a single-stage system with one hermetic compressor, a CFC- and HCFC-free refrigerant, and an air-cooled condenser that needs no liquid coolant. Dual displays show set temperature on one readout and actual chamber temperature on the other.
Power options cover 115V, 208V, and 230V at 60 Hz, 1-phase, plus 220V at 50/60 Hz, 1-phase. Exterior dimensions measure 57.5" × 29" × 46.5", with a shipping weight of 675 lbs. Manufactured in the USA and UL Listed, the LTF301C holds up to 16 racks of stored samples.
Key Features
- Digital control system: microprocessor controller with two displays, one for the set temperature and one for the actual chamber temperature.
- Alarm package: battery-operated audible and visual signal on mechanical or electrical failure, over- and under-temperature settings, silencing switch, and battery test switch.
- Remote monitoring: relay provided for remote alarm hook-up, plus a 1/2" access port for probes and cabling.
- Refrigeration: single-stage system with one hermetic compressor, CFC- and HCFC-free refrigerant, and an air-cooled condenser requiring no liquid coolant.
- Verified performance: every freezer is tested for 7 days under demanding conditions, with a constant low setpoint guaranteed in warm +30°C ambient environments.
- Sample storage: 255 L / 9 cu.ft. interior accommodating up to 16 racks.
How to Choose the Right Low-Temp Freezer
Selecting a low-temperature freezer comes down to matching cooling depth, storage volume, and site power to the samples you protect. Weigh these axes against your lab footprint and monitoring needs.
- Temperature range: confirm the lowest setpoint your samples require; the LTF301C reaches -40°C, suited to applications between 0°C and -40°C.
- Capacity: size interior volume and rack count to your inventory, since this unit holds 9 cu.ft. (255 L) and up to 16 racks.
- Control type: dual-display digital control lets technicians read setpoint and actual chamber temperature at a glance, reducing guesswork during audits.
- Voltage: verify available circuit power, as configurations span 115V, 208V, 230V at 60 Hz and 220V at 50/60 Hz.
- Footprint: measure your floor space against the 57.5" × 29" × 46.5" exterior and 675 lb weight before delivery.
- Safety and monitoring: battery-backed alarms and a remote relay matter when stored material cannot tolerate an unnoticed failure.
