A cascade refrigeration system with two hermetic compressors and CFC-free R-508B and R-404A refrigerants drives the unit to ultra-low storage temperatures.\u003c\/p\u003e\n\u003ch3\u003eWhat is the storage capacity and footprint of this freezer?\u003c\/h3\u003e\u003cp\u003eInterior capacity is 626 L (22 cu.ft.) with room for up to 36 racks. Interior dimensions measure 67\" × 19\" × 30\", and the exterior measures 98\" × 36\" × 43.5\", with a unit weight of 1,075 lbs.\u003c\/p\u003e\n\u003ch3\u003eWhat electrical configurations are available?\u003c\/h3\u003e\u003cp\u003eThe ULF801C is offered in 115V, 208V, and 230V at 60 Hz single-phase, plus a 220V 50\/60 Hz single-phase configuration. Confirm your lab circuit matches the configuration you order.\u003c\/p\u003e\n\u003ch3\u003eWhat materials is the cabinet constructed from?\u003c\/h3\u003e\u003cp\u003eThe chamber is 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel finished in powder-coated cool gray. This construction supports durable, long-term laboratory use.\u003c\/p\u003e\n\u003ch3\u003eHow does the freezer protect samples during a power or equipment failure?\u003c\/h3\u003e\u003cp\u003eA battery-operated alarm emits audible and visual signals on mechanical or electrical failure, with over- and under-temperature settings, a silencing switch, and a battery test switch. A remote relay enables facility monitoring, and an automatic timer restarts the unit after a power failure.\u003c\/p\u003e\n\u003ch3\u003eDoes this unit require manual defrosting?\u003c\/h3\u003e\u003cp\u003eYes, the ULF801C is a manual-defrost chest freezer.
