ULT and Cryogenic Freezers: Three Levels of Sophistication

	Ultra-Low Temperature and Cryogenic Storage Freezers

Three Levels of Sophistication
Performance, Reliability,
Selection and Craftsmanship

Revco freezers have earned a worldwide reputation for the highest standards of dependability and performance in demanding laboratory environments. Today, each chest and upright cabinet shares a basic technology and design platform common to all Revco freezers, while three distinct series - Ultima II, Elite and Value - offer multiple levels of control sophistication to meet your needs.

Refrigeration
Ultra-low models are available in four upright and six chest models, Ultima II, Elite and Value performance packages, each with the Legaci™ refrigeration sys-tem. Cryogenic models are powered by a patented orbital refrigeration system designed to maintain uniform cryogenic temperatures of -140°C and -150°C; available in Ultima II Series only.

Control Technology
The Revco IntrLogic™ controller, standard on Ultima II Series cabinets, features the industry's most advanced freezer, alarm and monitoring technology, protecting both stored product and the refrigeration system. IntrLogic™ supervises refrigeration cycles while managing information for multi-level security.

Electrical System
Because power management is critical to component reliability, each Revco freezer includes an on-board voltage boost system, standard.

Alarm
The Ultima II Series freezer alarm system provides the most comprehensive protec-tion available anywhere. The A.I.M. automatic incident monitor takes the guesswork out of what has occurred overnight, on weekends, holidays or anytime the freezer is unattended.

Monitoring
Extensive systems monitoring delivers real-time information to the IntrLogic™ microprocessor controller on Ultima II Series freezers. Control panel indicators create an intuitive display to verify freezer performance at-a-glance.

Cabinet Design
Refrigeration and electronic technology is integrated into a robust freezer cabinet which assures economical operation, structural stability and convenience in materials management. The door-mounted IntrLogic™ control on Ultima II Series upright models puts all information at eye-level.
