Mrazáky Mrazáky kryogenní
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.

  • The washable condenser filter keeps fins free of dust to maintain peak cooling efficiency; no tools required for removal
  • Low profile design with stay-open lid for easier access to inventory and insulated sub-lids for additional protection
  • Double seal lid gaskets minimise frost buildup and independent sub-lids provide additional protection

Exclusive IntrLogic™ microprocessor control system with touchpad data entry and digital display of all functions. Independent operating temperature and high/low limit alarm functions with factory-set defaults for quick start-up, all setpoints adjustable in 1 °C increments. Setpoint security system has a key-operated switch for main power and alarm. It features a standard RS-232 data port with system software for quick PC installation.

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 battery 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. RS232 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
