828L Ultra Low Temperature Freezer

828L Ultra Low Temperature Freezer

Purpose & Summary
The 828L ultra low temperature freezer is specially designed and manufactured for long-term storage of various biological products, including viruses, germs, erythrocytes, leucocytes and cutis. Applications can be found in blood banks, hospitals, epidemic prevention services, and research institutes, electronics and chemical plant laboratories, biological engineering institutes and marine fishery companies.

Special Features
1. Temperature Control
The 828L ultra low temperature freezer is controlled by microprocessor, digital display with a 1℃ temperature increment and an adjustable cabinet temperature range of -40℃ ~ -86℃.
2. Safety Control System
1) Malfunction alarms include conditions such as the temperature exceeding the set range, power failure, sensor error, voltage range exceeded, condenser under efficiency, and ambient temperature exceeding the acceptable range.
2) Audible and visible alarm indications via sounding buzzer and flashing light.
3) The 828L ultra low temperature freezer comes with multiple level protection functions which include password input, start-up delay protection, and voltage protection in the event of low or high voltage.
4) All individual parts are grounded safely.
3. Refrigeration System
1) Optimized cascade refrigeration technology utilizing a Danfoss compressor for highly-efficient refrigeration.
2) High-density and effective insulation for maximum temperature control.
3) Unique patented seal design, working together with the heat retardant system, keeps the cabinet from frosting.
4) The 828L ultra low temperature freezer has a specially designed low-temperature grade computer control system avoids common errors with the low-temperature grade compressor.
4. Ergonomic Design
1) LED display for easy observation of cabinet temperature, set temperature, ambient temperature, input voltage, temperature alarm settings and early warnings for malfunctions.
2) Adjustable multi-level shelf of this 828L ultra low temperature freezer for easy operation.
3) Safety lock to prevent unauthorized access.
4) Broad 10℃~32℃ ambient working temperature range.
5) Innovative integrated door handle and lock, compact casters, and flexible and easy operation.
6) Intelligent energy-saving condenser design.
7) The 828L ultra low temperature freezer has remote alarm access through the internet with advanced voltage compensation system in the event of high or low voltages.
8) Storage boxes are optional.
5. Vacuum Insulation Panel Technology.
Our advanced insulation technology uses the latest vacuum insulated panel material to guarantee a great seal and to pump out air between the insulation layers so as to minimize the heat conduction rate by optimizing heat conduction, heat convection and heat radiation. The VIP models have a better level of heat insulation, resulting in 30% more interior storage volume without increasing the dimensions of the cabinet.
6. Optional Intelligent Wireless Temperature Recorder
1) Sends alarm information to the user by SMS.
2) The 828L ultra low temperature freezer allows checking of the real time temperature and high and low temperature alarm values via SMS.
3) Allows setting of the cabinet temperature and temperature alarm values via SMS.
4) Remote monitoring of the machine at any time.
