LN2 Back-up System
Advantages
· Compact design, small footprint, can be placed on freezer top
· Temperature display, setting temperature adjustable by user
· USA-made ASCO brand cryogenic electromagnetic valve
Safety & Protection
· Valve test button to check whether electromagnetic valve works normally
· High/Low temperature alarm, low battery alarm
· Stop injection of LN2 when door opens, protecting user from being injured by liquid LN2 (need to be connected with ULT freezer door switch).
Reliability
· Stainless steel construction, rust-free, easy cleaning;
· Hose & injection tube with sponge cover for insulation
· Rechargeable battery for 48 hours working time.
