Antech advanced CO2 backup system BS-1 is to ensure optimal security for critical samples stored in Ultra
Low Temperature Freezers. It controls injection of CO2 into freezer when freezer temperature rises above the preset temperature value.
It also reminds users to fill or replace their CO2 cylinders when pressure is low.
CO2 Back-up System
Advantages
· Compact design, small footprint, can be placed on freezer top; 
· Temperature display, setting temperature adjustable by user;
· Unique low CO2 alarm, reminding user to change CO2 bottle in time;
· USA-made ASCO brand ultra-low temperature electromagnetic valve.
Safety & Protection
