Features
Specially designed compressor and cascade refrigeration system
Specially designed for rugged ultra-low temperature applications in a laboratory environment (HFC refrigerants only).
Micro-processor temperature control with LED digital display
Extremely accurate, easy-to-read display. The temperature inside the freezer can be set and monitored easily by means of a microprocessor temperature control with an LED digital display. The thermostat incorporates a platinum resistor (Pt. 100Ω), precision and durability.
Integrated cabinet design
High-performance refrigeration system with foamed-in-place cabinet insulation maximizes interior temperature uniformity and protects against fluctuating ambient temperatures.
Hot line for secure sealing
Moisture condensation at the top edges of the cabinet due to differences in temperature inside and out causes frost and icing problems that may reduce heat insulation efficiency and obstruct door movements. These problems are prevented by the “hot line” by means of which hot gas from the higher temperature circuit is circulated through the problem areas.
Maintenance
Filter check lamp notifys the user of a clogged condenser filter.The condenser filter is situated at the front panel to make filter removing and cleaning easier.
Ring back function
The alarm buzzer can be silenced by pressing the BUZZER key on the control panel. (The remote alarm signal is not cancelled.) Should the alarm condition continue after a certain suspension, the alarm buzzer sound will resume.
Self-diagnostic function
The temperature sensor, filter sensor and cascade sensor monitor operation conditions continuously. Should abnormality be picked up, an error code and the current temperature will be displayed in turn.
Standard casters and levelling feet
Standard-equipped heavy duty casters make it easy to move a freezer when necessary. The levelling feet keep a freezer level and firm on the floor.
Steady chamber temperature
The feature of the chest type is the low cold air leakage on door openings, and can keep a steady chamber temperature. Long frozen cell line, DNA, blood, and bone marrow, by high credibility, and precise temperature control.
Built-in temperature & power failure alarms (lamp / buzzer)
In case of power failure or an irregular rise in temperature, a rechargeable battery-operated indicator lamp and alarm will be activated. A compact recording unit which automatically records the inside temperature, and a backup system with liquefied CO2 or N2 which is selfactivated when a power outage occurs are also available separately. This equipment helps insure that the contents will be protected in the event of any power failure or mechanical trouble.
