Product Description This Revco/Thermo ULT430A freezer is used for storing reagents, pharmaceuticals, biologicals, and other laboratory materials at temperatures as cold as -30°C.
Heavy-duty refrigeration system is equipped with a hermetically sealed compressor. High-density, CFC-free urethane foam insulation minimizes the effects of ambient temperature fluctuations, reducing operating costs. Positive forced air circulation preserves temperature uniformity throughout the cabinet, while the directional airflow assures quick recovery following door openings. Automatic defrost feature maintains optimum cooling capacity. Automatic condensate removal eliminates the need for drain lines.
All freezer interiors and exteriors have a painted finish for scratch resistance and easy cleaning. Doors on all units are self-closing and feature keyed locks. Open wire shelves are zinc-plated and adjustable in 2.5cm (1") increments.
All units are controlled by the IntrLogic microprocessor system. Preset at -30°C, it offers icon-based controls, displays, and graphic references for easy, universal operation. Provides visual status reports on all critical functions. An enlarged digital display and a graphic thermometer accurate to 1°C allow conditions to be monitored at a glance. Settings are protected by a key-operated triple-position master switch that controls power to all systems. The IntrLogic control system also regulates the advanced digital defrost cycle, minimizing trace amounts of frost buildup and maintaining coil efficiency.
Audible and visual warnings for overtemperature, undertemperature, and power failure. Alarm silence, ringback, and automatic reset functions are standard. Push-button alarm test and backup battery assure system readiness. Remote alarm contacts are standard on all models.
