Inverter technology

. By sensing the set temperature and the real-time change of the temperature in the internal,the compressor running power is adjusted to achieve continuous and stable control of the temperature in the internal.
. In stable movement,reduce the running power of the compressor, the temperature in the internal is more uniform, improve the energy-saving effect.
. When the machine starts or opens the door to put the sample, improve the running power of the compressor,cool down faster,and the sample is more safe.

 Vacuum insulation technology

· VIP Vacuum insulation technology optimized U-Vacua vacuum insulation technology material+polyurethane foam insulation layer design, the overall thermal insulation effect reaches a new height, and the thermal insulation performance is increased by 20%.

 Security configuration

. The use of hydrocarbon refrigerant cascade refrigeration technology,cooling quickly after opening the door,to ensure the safety of samples.
· The unique expansion tank design can effectively stabilize the system pressure,maintain the normal operation of the compressor and extend the service life when the system pressure changes rapidly due to the change of ambient temperature or other reasons.
. Password protection of core parameters to avoid unnecessary losses caused by misoperation.

 Energy conservation and environment protection

. The use of pure natural refrigerant, fluorine-free environmental protection, greatly reduced charge, lower than the national 150g standard, safe and reliable.
. The power consumption of the whole machine is reduced by 20%, and the power consumption required for a single cryo tube is reduced to a new level.
