Overview
CryoCurtain™ represents a fundamental advancement in cryogenic dispensing technology. Unlike conventional nozzles that produce concentrated streams or uncontrolled spray patterns, CryoCurtain generates a uniform laminar sheet of liquid nitrogen across the entire target width.
This engineered approach to LN₂ distribution eliminates hot spots, reduces thermal shock, and maximizes cooling efficiency while minimizing nitrogen consumption. The passive mechanical design ensures reliable operation in the harshest industrial environments—no electronics, no moving parts, no maintenance headaches.
How It Works
Internal Plenum Conditioning
Liquid nitrogen enters a precision-machined internal plenum that conditions the flow and equalizes pressure across the entire width of the dispenser. This ensures uniform distribution before the LN₂ reaches the emission slot.
Laminar Slot Design
The conditioned LN₂ exits through a precision slot that produces a laminar sheet flow. The slot geometry is engineered to maintain flow stability and prevent turbulence, even at high flow rates.
Controlled Two-Phase Flow
As the LN₂ sheet contacts the target surface, controlled vaporization occurs across the entire coverage area. This two-phase flow dynamic maximizes heat transfer while minimizing splashing and boil-off waste.
Key Benefits
Improved Cooling Uniformity
Laminar sheet flow eliminates hot spots and ensures consistent temperature across the entire target surface.
Reduced LN₂ Waste
Efficient distribution and controlled vaporization minimize boil-off and runoff, reducing nitrogen consumption.
Minimized Thermal Shock
Uniform coverage prevents localized temperature extremes that can crack conveyor belts and damage substrates.
Equipment Protection
Reduced splashing and pooling protect surrounding equipment from cryogenic damage and ice buildup.
Passive Mechanical Design
No electronics or moving parts in cryogenic zone. Reliable operation in dust, vibration, and moisture.
Retrofit-Friendly
Integrates with existing LN₂ supply systems using standard industrial fittings. No major modifications required.
