About this item

• 【 Quick cooling effect is good 】Ultra-low temperature refrigerator adopts copper tube finned air cooled condenser, good cooling effect, fast cooling speed, stainless steel inner liner and plate tube type refined copper tube evaporator design, so that the refrigeration effect is better, and easy to clean.
• 【 Double door seal foam insulation door 】The use of double door seal foam insulation door and super thick insulation layer design further reduces the cold loss, saves energy consumption, and effectively extends the service life of the refrigerator. In terms of refrigerant, a new type of environmentally friendly low temperature mixed refrigerant is used, and the refrigeration system adopts all imported parts, which has good reliability and long service life.
• 【 Precise temperature control 】Ultra-low temperature storage box adopts imported microcomputer temperature controller, accurate temperature control, more accurate and safe. Digital display box temperature,Beautiful and easy to use, you can view and adjust the temperature and working state of the box without opening the door.
• 【Led indicator & Abnormal temperature alarm 】The * on the LCD screen indicates whether cooling is performed. When cooling is in progress, the display light is steady on; When the thermostat is waiting for minimum downtime (50% light 50% dark), the temperature of the probe will be displayed on the display. In the case of alarm, the following information is displayed (the alarm indicator is on and the buzzer buzzes) : E1 - temperature probe fault, rH - high temperature alarm, rL - low temperature alarm. In case of alarm, the internal buzzer and alarm indicator are activated to display the corresponding message. The buzzer can be silenced by pressing the SET key.
• 【 Scope of application 】270L Ultra-low temperature refrigerator can be used for scientific research, low temperature preservation of special ice cream and tuna products and low temperature experiments of special materials, etc., widely used in food freezing, scientific research institutes, industrial and mining enterprises, biological engineering research, electronic chemical industry, ocean fishing and other industries.

  Product Description

  

  Hear the sound of running water in the cryogenic chamber: this is the sound of refrigerant flowing in the pipeline.

  Compressor hot: When the compressor is working, its surface temperature can reach 70℃ ~ 90℃.

  When the storage box is working, both sides of the box (near the door) have a slight heat sensation. This is because the dew proof pipe is installed in the box.

  Condensation on the door seal: In rainy and humid season or in an environment with high relative humidity, there may be condensation on the outer surface of the case and the edge of the door seal. Just wipe it dry.

  The temperature in the box sometimes rises, exceeding the temperature control range of the set value: this is because the system defrosts at a regular time, and automatically recovers after defrosting.

  

  Storage essentials

  Run the goods in an empty container before storing them. After the container is in stable operation (it is best to run the container for more than 5 hours), wait until the container is fully cooled before putting the refrigerated goods into the container.

  One-time items or other products in the box should not be too crowded, should ensure that there is an appropriate gap, in order to facilitate the circulation of cold air in the box.

  Low temperature preservation box refrigeration system is used to maintain low temperature, not a quick freezing device, if you want to store large capacity (high water content substances), should be pre-cooled in other quick freezing device and then stored, so as not to cause the refrigeration system to run for a long time without stopping.

  When the initial storage capacity is large, the temperature should be gradually reduced, cooling 10℃ at each step, and holding heat for 1-2 hours until the stored temperature.

  When storing plastic bag products, be careful not to get close to the metal edge, so as not to scratch the plastic bag.
