User-friendly design

· Ergonomic latch，optional padlock，providing more user-friendliness.
· Controller has delay start function，enabling off-peak start for 0~30min，which significantly reduces the load on electric circuit from simultaneous start-up.
· Standard smart code lock，optional card-swiping unlock and fingerprint unlock.

 Sealing design

· Quadruple-pane door gaskets are distributed on different planes to form a vacuum protection area to prevent cold air loss and reduce frost growth.
· Wholly foamed inner door with thickness≥30mm.

 Safety design

. Original import compressor plus cascade cooling technology with HC refrigerants realizes rapid pull-down after door opening and ensures sample safety.
· Standard expansion tank to absorb system pressure in case of excessive pressure caused by extremely high ambient temperature or any other reasons, to maintain normal compressor operation and ensure sample safety.
· Core parameters protection with password to avoid unnecessary losses caused by mis-operation.

 Environmentally friendly

. Compared to products with the same capacity, energy consumption is reduced by 30%；
· Freon-free refrigerant, sealed refrigerant is significantly reduced (less than national standard 150g), safe and reliable.
· Energy consumption for each cryo-tube is reduced to a new low.
