Product Details
ultra-low temperature freezerTemperature control range: ambient temperature~-86 ℃ fluctuation: ≤± 2 ℃ uniformity ≤ 3 ℃
ultra-low temperature freezerIt has three cooling modes: rapid cooling, non-linear cooling, and linear cooling. The non-linear cooling function can edit the cooling program by itself, and should have RT standby time, target setting value, constant time, etc. After the program runs, it can be selected to stop or maintain.
Linear cooling mode: The system cools down uniformly to the target value, with a constant cooling rate of 2.2 ℃± 0.5/s.
Nonlinear cooling: The 12 stage cooling program can be set by customers themselves, and different cooling methods can be customized for different samples.
Rapid cooling: The system directly and quickly cools down to the target value, and the refrigeration system plays its maximum role, which can be used for rapid freezing and preservation of samples.
If an abnormal situation is detected, the system can automatically send a text message toUserThe product can be extracted through the network (3G \ \ 4G \ \ 5G \ \ wifi, etc.), and the data in the data box can be set. The data or curve graph can be viewed and downloaded on the client side.
ultra-low temperature freezerEquipped with * alarm functions: over temperature alarm, sensor fault alarm, low battery level alarm, high ambient temperature alarm, condenser malfunction alarm, power outage alarm, etc
ultra-low temperature freezerMain System Description
1. Control system
Adopting self-developed intelligent control system
4.3-inch color capacitive touch screen, multi-level password management, 7-inch color touch screen for 310L and above (excluding), dual independent cooling system, one cooling system abnormal, the other cooling system
It can still maintain the set value operation, and the screen intuitively displays the set value, actual value, ambient temperature, condensation temperature, Beijing time, etc
The system is equipped with a screen lock function to prevent unauthorized personnel from changing parameters
2. Refrigeration system
Adopting ultra-low temperature compressor
Adopting a full copper tube design, the surrounding evaporation pipeline has high uniformity
Single machine cascade refrigeration system, efficient and energy-saving
Mixed hydrocarbon refrigerant, not harmful to the atmospheric ozone layer, more environmentally friendly
3. The safety system product is equipped with a high-strength alloy tightening handle, built-in safety lock, and can also be equipped with a padlock (30L, 60L not included)
High strength locking casters prevent product displacement caused by uneven ground or vibration
IoT remote monitoring system, no need for complicated networking, simply scan the code to add products
4. Insulation system
Adopting high-density vacuum insulation foaming technology
10cm thick insulation layer effectively prevents loss of cooling capacity
