Filling systems

When applications dictate the need to take out small amounts of liquid gas quickly and frequently, a filling system may prove useful. A filling system is placed beside a tank in or outside the building to facilitate quick withdrawal of a few liters of liquid gas.

Demaco supplies two different types of filling systems:

  • Filling systems for filling mobile dewars (up to 400 liters)
  • Filling systems for the manual filling of well-insulated dewars (with a contents of a few liters)

Specifications

 Filling systems for mobile dewars typically consist of several components: a phase separator, valves, vacuum-insulated piping, and a control cabinet with HMI (Human-Machine Interface).

The system comes with a stainless steel frame and is suitable for filling both open and closed dewars. The filling system controls are placed at an ergonomic height while the connections are located at the back. High-flex tubes are used to connect the filling system to the dewars or mobile dewars.

The dewars’ filling system typically comprises high-flexible vacuum insulated tubing with a valve and control box to open and close the valve. This handheld box and tubing are simple to use and therefore ideally suited for filling small dewars.

Optionally, a prepaid card system can be added to the system.

Filling system applications

Filling systems are mainly used at small or test facilities or when several departments within one organization share a buffer tank. This way, each department has access to liquid nitrogen (or other liquid gases) when needed. User registration is often used in these cases, keeping track of exactly which department is consuming which quantities.

Our filling systems are primarily used for liquid nitrogen applications in laboratories, hospitals, and cryobanks. In these cases, the storage tank is often located outside. Employees refill their open dewars or closed transport containers whenever they need liquid nitrogen for their activities.

Accessory products

Our filling systems include a phase separator, level sensor, level controller, and valves.
