The marLiN2 is a fully automatic LN2 (liquid nitrogen) refill system. It is based on a high precision electronic weighing scale, a magnetic valve and an intelligent and versatile controller that automatically tops up an unpressurized LN2 dewar (typically 60 liters) from a supply line, e.g. a pressurized large LN2 dewar of 150l content or more. The marLiN2 system is the perfect addition to an Oxford Cryosystems Cooler (600, 700, 800 series) or similar systems and can be retrofitted easily to existing systems.
Other than competing products the marLiN2 system makes use of a scale and reliably refills a dewar for long periods of time. Since the heart of the instrument is a general purpose weighing scale, the marLiN2 system can generally be used for any application with th requirement to trigger some action at given weight thresholds and can easily be tailored to deal with other applications than cryogenic work.
The marLiN2 system features a state-of-the-art controller with full network connectivity and easy access from Windows, Mac OS X and Linux desktop as well as from mobile devices, either via native apps or via a web browser interface. The controller allows for defining fill levels and send emails or push notifications as soon as the corresponding level is reached.
HIGHLIGHTS
-
INTELLIGENT CONTROLLER
The marLiN2 system comes with a state-of-the-art controller with full network connectivity and easy access from Windows, Mac OS X and Linux desktops as well as from mobile devices, either via native apps or via a web browser interface. -
NETWORK CONNECTIVITY
The marLiN2 features an RJ-45 jack for connecting to your local LAN. An optional WiFi dongle allows for integrating the controller into your wireless LAN either as client or as server. -
MOBILE APP
Need to know how much nitrogen is left over in the dewar? Just take your phone or tablet and connect to the marLiN2 controller. A native Android and iOS app is available via the Google Play Store and Apple's App Store, respectively. -
AFFORDABILITY
The marLiN2 can be purchased as complete system including magnetic valve, isolated tubes and dewars or just as single component if you already own compatible dewars, valves or electronic scales. Contact us for a quotation based on your specific needs.
COMPONENTS
The marLiN2 refill system consists of individual components that may be purchased as a whole package or just as single items. If you already have suitable dewars or a compatible solenoid valve, they can be reused.

SOFTWARE
The user interface for the device is as simple as can be since the typical usage is a stand-alone operation for long periods of time. The instrument with reasonable presets for minimum and maximum fill levels that can easily be modified by software - no fiddling around with cryptic buttons and hard-to-read manuals.For ease of use, a full range of software is provided. Configuration and monitoring is most easily done from a web interface on any platform without having to install software. Mobile apps for Android and iOS are available from Google's Play Store and Apple's App Store, respectively. For more dedicated use with additional benefits, native executables are available for Windows, Mac OS X and Linux desktops. Desktop apps are compiled using Java 8u91 and may require a recent Java runtime environment.
