Norhof LN₂ Auto-Fill Systems provide precise, low-pressure control for custom and OEM applications where stable and reliable cryogenic delivery is essential. Our technology can be adapted to specific user requirements and seamlessly integrated into specialized systems or instruments.
Maintain Stable LN₂ Pressure
In many setups, controlled LN₂ pressure is crucial to ensure consistent flow to an external valve or component. Norhof systems maintain a stable supply pressure at low levels (typically ≤300 mbar), making them ideal for:
-
– Feeding a customer’s own LN₂ solenoid valve or dosing unit.
-
– Supplying LN₂ to custom-built manifolds or delivery lines.
-
– Maintaining pressure balance between a storage vessel and an external application.
This controlled, self-regulating pressure eliminates the need for high-pressure cylinders or manual interventions, offering safe and automated operation for continuous processes.

Controlled LN₂ Flow
When a defined and reproducible flow rate of liquid nitrogen is required, Norhof microdosing systems can provide accurate and low-vibration LN₂ delivery into a process line or cooling chamber.
Typical examples include:
-
– Supplying LN₂ at a steady rate to a small-scale cryogenic experiment.
-
– Providing constant or pulsed LN₂ flow to a sensor cooling stage or test fixture.
-
– Enabling smooth, automated refill of local dewars or intermediate reservoirs.
Flow and pressure settings can be customized according to the application, allowing integration with internal control logic or the customer’s own electronics (via optional I/O).
OEM Integration and Tailor-Made Solutions
Norhof also partners with OEMs to develop integrated LN₂ solutions for laboratory and industrial products. Our systems can be adapted for:
-
– Compact installation within an instrument housing.
-
– Special connector types, hose lengths, or fittings.
-
– Custom software interfaces and control logic.
Each Norhof system offers precision, safety, and repeatability — making it the ideal LN₂ source for any specialized or proprietary setup.
