A reliable LN₂ supply is not created simply by installing individual components. The external tank, piping, valves, control system, and cryocontainers must be technically coordinated and integrated into the facility's overall safety and operational concept.
Consarctic supports cryogenic projects from the initial needs analysis and technical planning through to installation and commissioning. We can also provide long-term maintenance, optimization, and 24/7 emergency support.
Consarctic combines consulting, planning, installation, and service into a fully coordinated, integrated solution.
Tank size, piping layout, points of use, and control systems are adapted to the requirements of the respective facility.
Certifications according to EN ISO 13485:2016 and ISO 9001:2015 cover, among other things, the development, project planning, installation, maintenance, and servicing of cryo-systems, as well as level monitoring, refilling, and alarm systems.
Consarctic offers maintenance and optimization services, as well as a 24-hour emergency service, 365 days a year.
An automatic liquid nitrogen supply system connects the central storage outside the building to the individual cryo-containers in the laboratory. The nitrogen is transported via vacuum-insulated lines and provided automatically based on the demand of the connected consumers.
The entire system essentially consists of four coordinated areas.
A large-volume outdoor tank serves as the central supply source. It is filled by the gas supplier and provides the necessary liquid nitrogen for the connected laboratory and cryo areas. The required tank size depends on factors such as consumption, the number of cryo-containers, desired delivery intervals, and potential future expansions.
From the outdoor tank, the liquid nitrogen reaches the individual points of use via a permanently installed piping system. The double-walled and vacuum-insulated lines limit heat ingress during transport. This reduces evaporation losses and allows the liquid nitrogen to be distributed efficiently, even over long distances.
Even with high-performance insulation, a portion of the nitrogen can evaporate during transport. This creates a mixture of gaseous and liquid nitrogen in the line. Phase separators vent the gas portion in a controlled manner, allowing the liquid phase to be delivered more consistently to the connected consumers.
The FMCS – Filling Management Control System coordinates the automatic supply of connected cryo-containers. It manages the designated filling sequences and provides relevant system information via a touchscreen interface.
When a cryo-container requires liquid nitrogen, the filling process is triggered automatically and monitored by the system. The exact scope of functions is tailored to the containers used and the facility's requirements.
For a reliable supply, all components must be planned together. Consarctic combines central storage, LN₂ transport, phase management, and control into a project-specific, integrated solution.
The outdoor tank provides larger quantities of liquid nitrogen for multiple cryocontainers or points of use. It is designed based on current consumption and the facility's planned development.
Planning takes into account factors such as the installation area, foundation, gas supplier access, tank volume, and pipe connections.
The pipelines connect the outdoor tank to the cryocontainers and other points of use within the building. Routing, pipe diameters, and connections are planned to suit the pipe length, flow rate, and spatial conditions.
Vacuum insulation limits heat ingress. This reduces evaporation during transport and can minimize condensation or icing on the outer pipe surfaces.
The FMCS serves as the central control level for the liquid nitrogen supply. It coordinates the filling of connected consumers and provides a clear overview of relevant system information.
Automation helps reduce regularly recurring manual filling tasks. This relieves the burden on laboratory staff and supports clearly defined supply workflows.
Phase separators separate the gaseous component from the liquid nitrogen before the medium is routed to the intended consumers.
Positioning and sizing are based on the system layout, piping routes, operating pressure, and the requirements of the connected cryocontainers.
An automatic supply system is particularly well-suited for biobanks, IVF centers, stem cell banks, research laboratories, and pharmaceutical or biotechnology companies that manage multiple cryogenic containers requiring regular refilling. Whether automation is the right choice depends on factors such as the number of units, nitrogen consumption, current staffing requirements, and plans for expanding the cryo-storage facility .
Retrofitting is possible in many facilities. To determine this, we examine the existing cryogenic containers, their connections, potential line routing, and the spatial requirements.
Based on this, Consarctic can assess which components can continue to be used and what technical adjustments are necessary for the automatic liquid nitrogen supply.
The Filling Management Control System handles the central coordination of automatic filling. It processes information from connected consumers and manages the designated filling sequences.
Furthermore, the system provides relevant facility information via a touchscreen interface. The specific functions depend on the respective configuration.
Vacuum-insulated lines limit heat ingress during transport. This results in less liquid nitrogen evaporation compared to less efficient insulation systems.
However, actual losses depend on several factors, such as line length, pipe diameter, operating pressure, frequency of withdrawal, and the overall system design. A reliable assessment is therefore only possible based on the specific installation.
The necessary measures depend on the size of the facility, the nitrogen quantities involved, room volume, ventilation, and potential incident scenarios.
During the planning phase, factors such as outdoor tank placement, shut-off devices, ventilation, oxygen monitoring, alarm systems, and operational emergency procedures must be taken into account. The specific safety concept is coordinated on a project-by-project basis with the operator and the relevant specialist planners.
Consarctic develops supply systems tailored to your spatial, technical, and operational requirements. Our range of services extends from initial needs analysis and planning to outdoor tanks, vacuum lines, and FMCS control, all the way to installation and long-term maintenance. Provide Consarctic with the key data for your facility. Based on this, we can determine how to implement a safe, efficient, and scalable LN₂ supply for your cryogenic containers.
