Harris® Classic™ freezers are designed for storing high-value critical products, and feature excellent temperature uniformity, fast recovery after door openings, and increased cooling capacity.

General Performance Features:

• Available in eight models with operating temperature ranges from -60 ºC to -85ºC
• Built to UL and CUL standards for safety and performance
• All models include Cryologic ® microprocessor control system (door-mounted on uprights)
• Enhanced refrigeration technology offers increased cooling capacity and faster temperature recovery
• Upright models equipped with CryoLatch ™ integrated door latch and handle
• Pressure Equalization Port equalizes cabinet pressure and allows re-entry to cabinet within 30 seconds of door closing (uprights only)

Control System:

• CryoLogic® microprocessor control system features touchpad data entry and digital display of all functions
• Setpoint security system features 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 setpoints 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 data port includes system software package
• Exterior alarm contacts connect to remote monitoring system
• Clean filter indicator light helps avoid clogged condenser air filter, improves cooling efficienty
• Alarm Reset button temporarily silences audible warning and re-activates automatically if condition remains

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 deviatinon 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 service

Universal Construction Features:

• Minmum 5 in. (127 mm) high-density, foamed-in-place urethane insulation is closed-cell and CFC-Free to protect product against high-ambient conditions.
• Access port is 1 in. (25mm) in diameter
• Heavy-duty swivel casters with (2) leveling feet
• Rounded interior corners, scratch-resistant painted interior and exterior surface allow for easy cleaning

Chest Cabinet Construction:

• Low-profile design allows for easier access to inventory
• Keyed lid lock provides security
• Insulated sub-lids minimize exposure during lid openings
• Conterbalanced lid seals reduce frost

Upright Cabinet Construction:

• Door-mounted controls
• Five shelves (four adjustable) create five interior compartments
• High-impact plastic inner doors feature magnetic latches to minimize exposure when retrieving contents
• CryoLatch ™ heavy-duty door latch with handle includes key lock and padlock provision for wasy door openings and sample security
