288L Ultra Low Temperature Freezer

288L Ultra Low Temperature Freezer

Purpose & Summary
The first 288L ultra low temperature freezer with a mobile message alarm and remote monitoring function in the world.
Haier ultra low temperature freezers are suitable for use in blood banks, hospitals, epidemic prevention services, research institutes, electronics and chemical plant laboratories, biological engineering institutes, and transoceanic fishery companies.

Special Features
1. Temperature Control
1) Adjustable temperature range of 288L ultra low temperature freezer from -40℃ ~ -86℃ in 1℃ increments.
2) Digital temperature display.
3) Microprocessor temperature control.
2. Safety Control
1) The 288L ultra low temperature freezer comes with a malfunction alarm which includes audible and flashing alarms for high and low temperatures, incorrect voltage settings, sensor failure, condenser efficiency defects, high ambient temperature, and power failure.
2) Multiple level protection includes password input, compressor start delay, ultra-high and -low pressure back up
3) All individual parts are grounded safely.
4) Every HAIER 288L 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 288L ultra low temperature freezer is equipped with extra thick, high-density insulation material for maximum temperature preservation.
2) High efficiency Danfoss compressor.
3) Optimized cascade refrigeration technology.
4) Specially designed computer control system for low temperature stage to prevent over loading of the second stage compressor.
5) The 288L ultra low temperature freezer is equipped with triple-layer sealing structure and heat-insulation system to reduce frost formation.
4. Ergonomic Design
1) LED display shows 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) All 288L ultra low temperature freezers come with a safety lock to prevent unauthorized access.
5) Broad 10~ 32℃ ambient working temperature range.
6) Innovative packaged casters and integrated door handle and lock design.
7) Pressure-equalization port for ease of re-entry after closing the door.
8) This 288L ultra low temperature freezer features of intelligently controlled condenser fan for higher energy savings.
9) Advanced remote monitoring and voltage compensation system.
Optional storage box.
5. VIP Temperature Preservation Technology
1) Reduced heat transmission into the 288L ultra low temperature freezer from ambient temperatures.
2) Improved insulation performance with thinner walls.
3) Small unit footprint area.
4) The 288L ultra low temperature freezer uses of pollution-free, nano-materials and CFC free.
5) Use of flame retardant VIP materials.
6) Increased ULT freezer interior volume.
