NORHOF LN2 Micro metering System-series#900and#800

Overview of Characteristics

-Trace liquid nitrogenLN2Precise control, from drip to drip1rise/minute.

- NORHOFThe low-temperature liquid nitrogen system produced has no pressure and is as simple and smooth to use as pouring water from a teapot.

-liquid nitrogenLN2Variable flow rate, suitable for different needs and applications, automatically controlled or remotely controlled by the system.

-Variable and controllable liquid nitrogen flow rate (through corresponding settings, sensors, remote control signals, or computers)

-liquid nitrogenLN2Flow without splashing, noise, vibration, etc

advantage:

-need notLN2Electromagnetic valve means no need for additional heating input

-No need for additional control units, meaning a neat and effective layout

-The pump is driven by software and includes multiple preset control modes

-The liquid level and temperature sensors are directly connected to the pump body without the need for an additional control box.

-The system can driveLN2Smooth and quiet flow, no noise or vibration, and no waste

-Various flow characteristics make it particularly easy to control sub zero temperatures

-The system is easy to accessPCComputer, convenient for saving history and remote control

-The system is not affectedP.E.D.99/36/EC (Pressure European Directive)

Minute traffic system

Working principle-100When a small amount of liquid nitrogen is heated at the bottom of the Dewar flask, pressure begins to accumulate at the top of the flask. When the overpressure reaches

Millibars, liquid nitrogen begins to slowly flow out.-

The pressure at the top of liquid nitrogen and the flow of liquid nitrogen are precisely controlled.-

We accumulate pressure by evaporating some liquid nitrogen, so there is no need to add ice to the Dewar flask (such as manually using external ambient air).-weNORHOF

The storage pressure of liquid nitrogen in the liquid nitrogen cooling system is lower than that of the Dewar flask. When liquid nitrogen is needed, a small overpressure is generated by heating the liquid nitrogen, and the liquid nitrogen flows out like tap water without splashing, noise, or vibration.

Application mode:

There are multiple modes to choose from:-Flow control type

(model #905)-Traffic and/Or temperature controlled type

(model #910)-Remote control or historical record control type

(model#915)-Air conditioning output type( #805, #810,

#815),high energy gas

(#855)

-Industrial application improvement type (customized)

Mode characteristics-All models have a similar appearance and can be set differently internally, making them suitable for various applications.-

All models can be connected to a computerPCDisplay system status parameters. Each pump comes with corresponding software and hardware.-

Customers can view our liquid nitrogen system as a liquid nitrogen generator with a controllable temperature and flow range (from ambient temperature to-196°C）. This controllability can be achieved manually or remotely.-Our liquid nitrogen system is designed to overcomeLN2Under pressure, an electromagnetic valve is required to switch the power on/

By controlling the pressure during liquid transfer, it is possible to achieve a transition from ambient temperature to

-196°CAny temperature and flow control between them.

For example, various modes can be easily implemented without the need to modify the following factors:-Automatic operation unit-Direct remote control unit (via customer)PIDcontroller,PLC
