Platinum Chest Style Ultra Low Freezers -40°C To -80°C, 21Cu.Ft., Manual Defrost Overview
The Platinum Chest Style Ultra Low Freezers -40°C To -80°C, 21Cu.Ft., Manual Defrost (model ULF701CP) is a 21 cu.ft. chest-style ultra-low laboratory freezer reaching -40°C to -80°C. A touch-screen digital controller displays set point and chamber temperature. Audible and visual alarms, remote alarm contacts, USB and Ethernet ports, data acquisition, battery alarm back-up, and a 1/2" access port all come standard from Yamato Scientific.
Chamber walls use 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel finished in powder-coated cool gray. Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and R-404A refrigerants. Air-cooled condensing with two heavy-duty fans removes any need for liquid coolant. A 1/2" access porthole sits on the left-hand cabinet wall with plugs.
Electrical input accepts 115V, 208V, or 230V at 60 Hz single-phase, plus a 220V 50/60 Hz single-phase option. Exterior dimensions measure 91" × 36" × 49" (231 × 91 × 124 cm), and shipping weight is 1,075 lbs. Built in the USA and UL Listed, the unit holds 36 racks across 594 L of interior space. Automatic power-failure recovery restarts operation after an outage.
