Stirling Cryogenics StirLITE Liquid Nitrogen System is avaliable in our laboratory.

Production Capacity : 60L/Day

Nitrogen Purity : %99

System Features:

  • Ease of installation. With the system room and utilities prepared prior to the arrival of the system, the StirLIN will be producing liquid nitrogen within a few days after opening of the crate. During the visit of one of our service engineers the StirLIN will be installed and commissioned. Your personnel will be trained how to optimally operate the system.
  • Fully automatic operation by PLC control. All StirLIN systems are monitored, controlled and safeguarded by a Programmable Logical Controller (PLC). Through the display, the operator is continuously informed about the operational status of the system such as the liquid nitrogen level in the storage vessel. For efficient troubleshooting, messages of the safety devices are indicated as error codes that refer to the operator manual for further action. The PLC will automatically stop and start the StirLIN depending the level of liquid in the storage vessel. In case of power or water supply failure, the PLC automatically re-starts the StirLIN when the supply is restored.
  • Extendible LN₂ production capacity . Our Extendible StirLIN’s are the solution for customers of which the LN₂ consumption is expected to grow in the future. By offering the StirLIN Extendible systems, customers do not need to invest in a system that is too large for this moment, while giving them the opportunity to easily double the capacity in the future, without the need to purchase a second system. The Extendible systems are prepared for future growth in LN₂ consumption. All components are sized for increased capacity with all the necessary connections and controls already integrated. The main system is delivered with only one SPC cryogenerator, which determines its initial capacity. Once LN₂ consumption of the customer has grown to such extend that increase production capacity is required, the customer can purchase the second cryogenerator and water chiller. By connecting this to the already prepared existing system, the LN₂ production rate of the system is doubled.
  • Adjustable liquid nitrogen pressure. The StirLIN is equipped with a pressure regulator to adjust the pressure at which the liquid nitrogen is kept in the storage vessel. This allows the customer to choose the pressure that best suits his application. This also prevents high losses by flashing due to unnecessary over pressure in the storage vessel.
  • Efficient production. The StirLIN’s are designed around the highly efficient Stirling cycle. Economical use of electrical energy results in low electricity consumption per liter of LN₂ produced.
  • Easy liquid nitrogen dispense. The storage vessel is equipped with a manual valve and a flexible delivery hose. Dispensing of liquid nitrogen can be done in several ways, depending the type of dewar to be filled:
    • Open dewars are filled by placing them beside the StirLIN vessel and dispensing the liquid through the flexible hose into the dewar opening.
    • Closed dewars can be filled by connecting the flexible hose to their fill connection and opening valves according instructions of dewar manufacturer.
    • For applications with an auto-fill system, an optional direct connection hose can be installed between the StirLIN vessel and the application.
  • Low noise level. The noise level of the StirLIN is only 70 – 74 dBA depending on the type of StirLIN. This allows a normal conversation in the system room in direct vicinity of the system.
  • Built for stringent climate conditions (and adaptable to extremes). Functional specifications of StirLIN systems are defined at the nominal conditions of 250 m altitude and 25°C air temperature. Their working range is however much larger. At altitudes up to 2.000 m or temperatures up to 45°C ambient temperature a standard StirLIN will still perform. For more extreme circumstances a StirLIN can be adapted to your specific climatic conditions such as high altitude or hot deserts.
