Nor-Lake Scientific -86ºC ULT Upright Freezers

• Provides energy efficient, convenient, safe and reliable performance for optimal storage temperature environments necessary for a wide range of life science, pharmacy, biological, medical, clinical, and industrial applications.
• CFC-free polyurethane cabinet and door foam insulation.
• High-impact, smooth scratch- and corrosion-resistant white painted exterior and smooth white painted interior. Interior and exterior are galvanized steel.
• Ensures reliable frost resistant performance and enhances energy efficient cold performance for long term sample security and storage.
• Five interior doors (hinged steel inner doors) have insulating material with magnetic catch and easy pull handles. Reduces cold loss during door openings and sample retrieval.
• Four heavy-duty reinforced stainless steel shelves. Shelves are adjustable in 1” increments. Compatible with optional stainless steel storage racks, fiberboard boxes and dividers for multiple storage needs.
• Multi-feed cold wall evaporator design provides superior refrigerant flow and maximizes cooling power by ensuring that the evaporator is always 100% in contact with the freezer wall, maximizing cold transfer into the freezer and heat removal from the chamber.
• Easy-open integrated outer door latch and handle allows one-handed opening and closing. Door latch and key lock for added security.
• Chamber vacuum relief system allows convenient and fast re-entry to cabinet upon outer door closing.
• Door activated electro-magnetic switch for use with door ajar alarm, optional CO2/LN2 backup systems and vacuum relief system.

• Advanced PLC microprocessor controller (door mounted eye level display) includes real time clock, event logging alarm history, advanced alarms, alarm-test and memory function.
• Password protection for power, temperature and alarm settings.
• Temperature adjustable in 0.1ºC increments. Temperature display to 0.1ºC increments.
• Power failure, hi/low temperature and door ajar indicator alarms (audible and visual).
• Remote alarm contact connections located on back of cabinet for easy installation.
• Compressor protection monitors compressor performance and automatically adjusts to internal and external conditions.
• Delayed startup (programmable) delays freezer restart after power interruption.
• Surge protection minimizes voltage spikes and protects system electronics.
• Voltage boost/buck system ensures proper operating voltage to operating system.
• On-board system and maintenance diagnostics continuously monitors system sensors to ensure optimal freezer performance.
• 23-hour backup microprocessor battery continuously recharged with low battery indicator.
• Dry erase board and pocket storage organizer. Dry eraser and markers included.
• Advanced low-noise high-performance cascade refrigeration system using two 1HP hermetically-sealed compressors.
• Exclusive engineered super capacity (tri-tube) capillary tube system delivers refrigerant on demand matching with advanced heat exchanger design providing optimal heat removal and superior low temperature performance.
• Evaporator design enhances refrigerant flow increasing the overall efficiency, temperature uniformity and recovery performance.
• Air cooled condenser, high capacity with large surface area. Washable condenser filter maintains optimal efficiency and performance. Clean filter indicator advises when to clean.
