Chest Style Low Temperature Freezers 0°C To -40°C, 14 cu.ft., Manual Defrost Overview
The Chest Style Low Temperature Freezer LTF501C from Yamato Scientific is a 14 cu.ft. (400 L) laboratory chest freezer delivering a setpoint range of 0°C to -40°C with manual defrost. Sold by LabSupplies.com, authorized dealer, this unit ships standard with a microprocessor digital controller, audible and visual alarms, remote alarm contacts, alarm battery back-up, and a 1/2-inch access port.
Construction targets long service life under demanding lab duty. A 14-gauge zinc-coated galvanized steel chamber resists corrosion, while the 16-gauge steel exterior carries a powder-coated cool gray finish. Single-stage refrigeration with one hermetic compressor, an air-cooled condenser, and a CFC- and HCFC-free refrigerant keeps the design serviceable without liquid coolant. Dual displays show set and actual chamber temperatures.
Operational fit suits most North American lab circuits, with electrical configurations spanning 115V/208V/230V at 60 Hz and 220V at 50/60 Hz, single-phase. Footprint measures 72.5 × 33 × 47.5 inches exterior, and shipping weight is 900 lbs. Built in the USA, the LTF501C is UL Listed and rated to hold a constant low setpoint in warm +30°C ambient environments.
Key Features
- Microprocessor digital control: two displays show the set temperature and the actual chamber temperature for at-a-glance verification.
- Dual-mode alarm system: battery-operated audible and visual signal triggers on mechanical or electrical failure, with over- and under-temperature settings, an alarm silencing switch, and a battery test switch.
- Remote alarm relay: integrated relay supports remote alarm hook-up to building monitoring systems.
- Refrigerant-conscious cooling: single-stage hermetic compressor with an air-cooled condenser uses CFC- and HCFC-free refrigerant and needs no liquid coolant.
- Validated performance: every freezer is tested for 7 days under demanding conditions to guarantee a constant low setpoint even at +30°C ambient.
- Rack capacity: chamber accepts up to 30 racks across its 62 × 20 × 20 inch interior.
How to Choose the Right Low-Temp Freezer
Selecting a chest low-temperature freezer comes down to matching sample volume, setpoint depth, and site infrastructure to your storage protocol. Use the criteria below to confirm the unit fits your workflow .
