The operating costs of a cryobank are dominated by a factor that is invisible at first glance: the evaporation of liquid nitrogen. No cryogenic tank is perfectly insulated - heat always penetrates the system and nitrogen evaporates continuously. This so-called boil-off is the largest single operating cost item of a cryogenic facility.
In times of rising energy prices and a growing awareness of sustainability, the issue of energy efficiency in cryogenics is becoming increasingly important. But efficiency must never come at the expense of safety. The trick is to optimize both at the same time.
Consarctic® is committed to this balancing act. In this article, we analyze the levers for greater efficiency and show how well thought-out product design can significantly reduce the total cost of ownership (TCO) of a cryobank.
The daily consumption of liquid nitrogen is directly proportional to the quality of the tank insulation, the frequency of tank openings and the efficiency of the refilling process. A single poorly insulated nitrogen tank can drive up the consumption of the entire bank disproportionately.
Manual processes such as decanting LN2, inventory control and visual inspection of the tanks tie up qualified personnel. Every hour that a scientist spends on logistics is one hour less spent on research.
Regular maintenance is essential to maximize the service life of the appliances and avoid unplanned downtime. The quality of the materials used and the quality of workmanship have a direct impact on maintenance costs.
Laboratory space is expensive. The more samples that can be stored in a tank, the less space is required per sample - an often underestimated cost factor.
The Consarctic® stainless steel tanks in the BSD+ and BSF+ series set standards in terms of energy efficiency:
Switching from manual filling to an automatic liquid nitrogen supply via vacuum lines is one of the most effective levers for reducing costs. The advantages are manifold:
The Biosafe monitoring system from Consarctic® provides real-time data on fill levels and temperatures of all connected tanks. This data enables predictive maintenance and optimization of supply cycles. Instead of reacting to alarms, operators can plan proactively.
Consarctic® cryo set-up systems are designed to make optimum use of the available interior space of the tanks. Tailor-made racks and cassettes maximize the number of samples stored per tank - and therefore per square meter of laboratory space.
Energy efficiency in cryogenics is not just an economic issue - it is also a question of responsibility. Those who reduce their nitrogen consumption also reduce their ecological footprint. Consarctic® is proud to contribute to more sustainable laboratory practices with its innovative cryogenic products.
