Designed for long-term storage of biologicals, blood components and pharmaceuticals, these freezers incorporate the latest refrigeration and microprocessor-based control technology developed to increase reliability, stability and dependability. The refrigeration system involves an exclusive mixed refrigerant (CFC-free) autocascade with a single, orbital refrigeration compressor, air-cooled. Downfeed evaporator for most efficient refrigerant flow, and high-capacity air-cooled condenser with dual condenser fans, aerodynamically shaped fan blades.
A.I.M. (Automatic Incident Monitor) identifies any temperature deviation beyond alarm setpoints, with rapid flash for current event, slow flash if event was self corrected; A.I.M. archives most deviated temperature. An adjustable safety alarm with automatic, continuous charge battery backup provides full function in case of power failure. Power failure or temperature deviation triggers audible and visual warning . Digital batter indicator displays battery capacity; flashing low battery indicator advises when to replace battery. Touchpad alarm test function physically warms internal probe to simulate alarm condition. RS-232 data port with system software package. Exterior alarm contacts for connection to remote monitoring system.
Operating temperatures: −140 °C for the ULT101140-9-M model and −150 °C for the ULT7150-9-M
