Chest Style Low Temperature Freezers 0°C To -40°C, 17 cu.ft., Manual Defrost Overview
The Chest Style Low Temperature Freezers 0°C To -40°C, 17 cu.ft., Manual Defrost (model LTF601C) is a chest-style laboratory freezer from Yamato Scientific. This unit holds 480 L (17 cu.ft.) of sample storage and maintains any setpoint from 0°C down to -40°C. LabSupplies.com stocks it 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 drives cooling, and the air-cooled condenser needs no liquid coolant. Refrigerant is CFC- and HCFC-free. Two digital displays read the set temperature and the actual chamber temperature separately.
Electrical options cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz. Exterior dimensions measure 81.25" × 33.5" × 48.5", and shipping weight is 975 lbs. Built in the USA, the freezer carries UL Listed certification and arrives after a 7-day performance burn-in.
Key Features
- Microprocessor digital control: two displays show the set temperature and the live chamber temperature at the same time.
- Battery-backed alarm system: audible and visual signals trigger on mechanical or electrical failure, with alarm battery backup.
- Over- and under-temperature protection: adjustable settings, an alarm silencing switch, and a battery test switch are standard.
- Remote alarm relay: built-in remote alarm contacts let facilities tie the unit into a central monitoring system.
- 36-rack interior: 480 L (17 cu.ft.) chamber accepts up to 36 racks, plus a 1/2" access port for probes or recorders.
- 7-day factory testing: every freezer is fully tested for 7 days and holds its low setpoint in warm +30°C ambient environments.
How to Choose the Right Low-Temp Freezer
Matching a chest-style freezer to your protocol comes down to a few measurable axes. Review these criteria against your samples, site, and monitoring needs before specifying a unit.
- Capacity: the 480 L (17 cu.ft.) chamber and 36-rack layout determine how many samples you can store; size it to current volume plus growth.
- Temperature range: a 0°C to -40°C span suits samples that do not need ultra-low -80°C storage, so confirm your target setpoint first.
- Control type: dual digital displays separate set and actual temperature, giving technicians a clear read during routine checks.
- Voltage: match the unit to your circuit; options include 115V, 208V, 230V at 60 Hz and 220V at 50/60 Hz, single-phase.
- Footprint: verify the 81.25" × 33.5" × 48.5" exterior and 975 lb weight clear your doorways and floor rating.
- Safety and monitoring: battery-backed alarms and a remote relay matter for unattended or after-hours storage.
