Ultima II Series Cryogenic Operating Temperature

• -150°C, Model ULT-7150-9
• -140°C, Model ULT-10140-9
• Air-cooled refrigeration systems are engineered to maintain design temperatures in warm ambient conditions:

Model ULT-7150-9, +30°C (+86°F);

Model ULT-10140-9, +32°C (+90°F)

Cryogenic Temperatures Without Liquid Nitrogen

• REVCO® Ultima II cryogenic freezers are designed for long term storage of biologicals at uniform temperatures of -140°C and -150°C, safely below the -130°C glass transition temperature of water
• Cell viability is improved because biologically relevant, thermally driven reactions are not known to occur

Safer, More Convenient Than LN ₂

• REVCO cryogenic freezers include all features, control and performance attributes of the Ultima II Series freezers, plus many important advantages not available when using LN ₂
• Stable cryogenic temperature of -140°C and -150°C without LN ₂ as a cooling medium
• Patented, single compressor, orbital refrigeration system
• Top-to-bottom temperature uniformity dramatically improved when compared to LN ₂ vapor
• Lower operating costs than LN ₂ freezers of similar capacity
• 100% of interior space is usable, with stored samples maintained below critical temperature
• Ample interior volume with capacity of up to 21,600 samples in Model ULT-10140 and up to 14,400 samples in Model ULT-7150 (2 ml vials in boxes)
• Uses standard REVCO inventory racks and fiberboard boxes; see Accessories

Refrigeration System

• Exclusive mixed refrigerant autocascade with a single, orbital refrigeration compressor, air-cooled
• CFC-free refrigerants
• Downfeed evaporator for most efficient refrigerant flow
• High-capacity air-cooled condenser with dual condenser fans, aerodynamically shaped fan blades
• Washable condenser filter keeps fins free of dust to maintain peak cooling efficiency; no tools required for removal

Control System

Exclusive IntrLogic ^TM microprocessor control system with touchpad data entry and digital display of all functions

• Setpoint security system with key-operated switch for main power and alarm locks in temperature and alarm setpoints
• Independent operating temperature and high/low limit alarm functions with factory-set defaults for quick start-up, all setpoints adjustable in 1°C increments

Electrical System

• Automatic voltage boost compensates for low voltage and brownout conditions
• On-board power monitoring with digital readout of incoming line voltage
• Built-in surge suppressor minimizes effect of voltage spikes from incoming electrical service

Alarm System

• 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
• 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
• RS-232 data port with system software package
• Exterior alarm contacts for connection to remote monitoring system

Monitoring System

• Lifeguard compressor protection monitors performance and automatically adjusts to internal and external conditions, extending compressor life
• Extreme ambient alert warns if room temperature may affect performance
• Voltage boost indicator advises of low source voltage below safe parameters and indicates voltage boost system is activated
• Surge suppressor indicator advises to check intercept fuse
• Clean filter indicator light advises when to remove and wash condenser filter

Chest Cabinet Construction

• Low-profile design for easier access to inventory
• Heavy duty counterbalanced lid with integrated keyed lid lock for security
• Double seal lid gaskets to minimize frost buildup
• Independent sub-lids provide additional protection
• Minimum 5" (127mm) foamed-in-place urethane insulation, closed-cell, CFC-free, to protect product against high ambient conditions
• Heavy-gauge steel cabinet with high-impact powder paint finish
• Rounded interior corners for easy cleaning
• Access port, 1" (25.4mm) diameter, with cap
• Recessed heavy duty swivel casters
