The Harris^® Cryostar^® Series combines the savings and convenience of mechanical refrigeration with the advantage of cryogenic temperature performance.

General Performance Features:

• Available in two low-profile cabinet sizes
• Maintains uniform -140 ºC or -150ºC temperatures
• Built to UL and CUL standards for safety and performance
• Includes CryoLogic^® microprocessor control system
• CFC-free refrigerants and insulation on all models

Control System:

• CryoLogic^® microprocessor control system with touchpad data entry and digital display of all functions
• Setpoint security system with tamper-proof, 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 setpoint adjustable in 1ºC increments

Alarm System:

• Adjustable safety alarm with automatic, continuous-charge battery backup provides full alarm 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
• Standard RS-232 daat port includes system software package
• Exterior alarm contacts connect to remote monitoring system

Monitoring System:

• Extreme Ambient Alert warns if room temperature is too warm due to seasonal air conditioning or other factors which may affect performance
• Silent Witness Alert archives temperature deviation beyond pre-set parameters

Electrical System:

• Automatic voltage boost compensates for low voltage and brownout conditions
• On-board power monitoring features digital readout of incoming line voltage
• Optional free-standing surge suppressor minimizes effect of voltage spikes from incoming electrical serivce

Chest Cabinet Construction:

• Low-profile design allows for easier access to inventory
• Minimum 5 in. (128 mm) high-density, foamed-in-place urethane insulation is closed-cell and CFC-free to protect product against high-ambient conditions
• Keyed lid lock for secrity
• Insulated sub-lids minimize exposure during lid openings
• Counterbalanced lid seals reduce frost
• Access port is 1 in. (25 mm) in diameter
• Heavy-duty swivel casters
• Scratch-resistant steel exterior rounded, painted interioor corners for easy cleaning

Refrigeration System:

• Single compressor system
• Achieves and maintains uniform -140ºC or -150ºC temperatures
• Downfeed evaporator provides optimally efficient refrigerant flow
• CFC-free refrigerants
• Sound-absorbing insulation
