388L Ultra Low Temperature Freezer

388L Ultra Low Temperature Freezer

Purpose & Summary
The first 388L ultra low temperature freezer with mobile message alarm and remote monitoring function in the world.
Haier ultra low temperature freezers are suitable for applications in blood banks, hospitals, epidemic prevention services, research institutes, electronics and chemical plant laboratories, biological engineering institutes, and transoceanic fishery companies.

Special Features of 388L
1. Temperature Control
1) The 388L ultra low temperature freezer is equipped with digital temperature display.
2) Microprocessor temperature control.
3) Adjustable temperature range of -86℃ Freezer from -40℃ ~ -86℃ in 1℃ increments.
2. Safety Control
1) The 388L ultra low temperature freezer comes with a malfunction alarm which includes audible and flashing alarms for high and low temperatures, incorrect voltage setting, sensor failure, condenser efficiency defects, high ambient temperatures, and power failure.
2) Multiple level protections includes password input, compressor start delay, ultra-high and -low pressure back up.
3) All individual parts are grounded safely.
4) Every HAIER 388L ultra low temperature freezer has a controller on the front of the cabinet door with built-in software which displays the necessary components (such as compressors, voltage sensors, and cabinet and ambient temperature sensors) to aid in quickly identifying the cause of a fault or set a temperature variance. We call this SYSTEMS MONITORING AND REPORTING TECHNOLOGY and it enables display of the part that is having a problem on the controller itself. This type of inbuilt fault identification can help the customer identify and report to our service staff which part is in need of repair should it become necessary for our service engineers to come onsite.
3. Refrigeration System
1) The 388L ultra low temperature freezer comes with optimized cascade refrigeration technology.
2) High efficiency Danfoss compressor.
3) Extra thick, high density insulation material for maximum temperature preservation.
4) The -86℃ Freezer is designed with triple-layer sealing structure and heat-insulation system to reduce frost formation.
5) Specially designed computer control system for low temperature stage to prevent over loading of the second stage compressor.
4. Ergonomic Design
1) The 388L ultra low temperature freezer is equipped with an LED display for viewing of cabinet temperature, set point temperature, ambient temperature, and input voltage.
2) Adjustable high and low temperature alarm set points.
3) Multiple shelves for storage of various sized samples.
4) Safety lock to prevent unauthorized access.
5) Broad 10~ 32℃ ambient working temperature range.
6) Innovative packaged casters and integrated door and lock design.
7) The 388L ultra low temperature freezer has a pressure-equalizing port for ease of re-entry after closing the door.
8) Intelligently controlled condenser fan for higher energy savings.
9) Advanced remote monitoring and voltage compensation system.
10) Optional storage box.
5. VIP Temperature Preservation Technology
1) Reduced heat transmission into the 388L ultra low temperature freezer from ambient temperatures.
2) Improved insulation performance with thinner walls.
3) Small unit footprint area.
4) Use of flame retardant VIP materials.
5) Increased 388L ultra low temperature freezer interior volume.
6) Use of pollution-free, nano-materials and CFC free.
