2 -86ºC-Freezers Constant -86ºC Microprocessor Temperature Control Improved Design Temperature & Power Failure Alarms Digital display. These ultra-low temperature freezers are designed by Sanyo to maintain internal temperature as low as -86º C (-123ºF), at an ambient temperature of +30ºC (86ºF). They are ideally suited for use in hospitals and laboratories, for long-term preservation and storage of blood, specimens and components, and in testing of various types. Ranging in size from economical chest freezer to largecapacity, one of these models is sure to be suitable for your needs. Advanced features include a microprocessor temperature control system with digital temperature display, a platinum resistance sensor for extra precision and reliability, a power failure warning system with built-in audible and visible indicators, doubleinsulation polyurethane walls and easyopen/easy-close hinged door. AT models also offer automatic temperature recording and CO 2 back-up system. Dimensions Note: This diagram is for MDF 792 AT. Model Symbol (A) (B) (C) (D) (E) (F) (G) (H) (I) (J) (K) LITER 44

5 Function creates form Ultra-Freezing in Minimal Space Super freezing capability below -86ºC (-123ºF) Even with ambient temperature of 35ºC (95ºF), ultra-low temperature of -86ºC (-123ºF) can be maintained. This is made possible by means of a compact and super-efficient freezing circuit employing a miniature heat exchanger in combination with a 3 gas mixed refrigerant freezing circuit. 86 LITER Low-profile design for easier loading and unloading. The chest-type design provides relatively stable inside temperature and occupies a mere 29.5 (W) x 27.6 (D) (75cm x 70cm) of space. The low profile greatly facilitates loading and unloading.
