Milder winters and uncertain snow conditions threaten major ski events globally. Organizers face huge financial risks and logistical nightmares if races are cancelled or conditions are unfair. The traditional method of storing and transporting massive snow piles is labor-intensive and costly. But what if you could treat and freeze existing snow and wet trails on demand?
The Problem with Today’s Snow Management: Conventional cooling methods, like spraying liquid nitrogen directly onto the surface, are incredibly inefficient and consume massive amounts of coolant—up to 100,000 liters of gas per 100 meters in some older methods. This is primarily because the cold gas mixes and blows away almost instantly.
A Patented Solution: The Sealed Cooling Machine (The Ice-Maker on Skis): The innovative mobile cooling machine (Patent SE 542 647 C2) solves this by creating a sealed unit with the surface being treated.
- Encapsulation for Efficiency: The core innovation is a moving machine that forms a tightly sealed enclosure around the treatment area using insulating members and blades. This simple sealing mechanism dramatically traps the refrigerated air (from dry ice, liquid nitrogen, or carbon dioxide).
- Cost Minimization: By containing the cold air and creating a higher air pressure inside the unit, the consumption of expensive coolant is optimized and minimized. This makes on-demand trail freezing economically viable.
- Precision and Quality Control: The FrykenFrost™ snow technology system uses internal temperature and air pressure sensors to continuously monitor conditions within the sealed area. A central controller automatically regulates the flow of refrigerant (via a gas tap) to ensure the precise, optimal temperature and pressure are maintained, guaranteeing a consistently frozen and high-quality trail.
Conclusion: This technology offers a reliable, cost-effective, and environmentally friendly way for ski resorts to secure their event calendars and provide fair, rock-solid racing conditions, regardless of uncooperative weather. The future of winter sports is here, and it’s sealed, measured, and perfectly cold.

TECHNICAL PROOF-OF-CONCEPT: Cryogenic Cooling Module for Surface Freezing
Patent Status: CA2993889A, NO337419B1, SE542647C2.
Application: Rapid stabilization and surface freezing of ski tracks, winter roads, and competition surfaces.
1. Executive Summary
This document provides the mathematical and thermodynamic validation for a patented cryogenic cooling system. By utilizing liquid nitrogen ($LN_2$) in a sealed, ground-interfacing chamber with forced convection, the system extracts heat at a rate significantly higher than ambient cooling. The primary innovation lies in the elimination of the gas-insulating layer (Leidenfrost effect) and the use of the ground as the “sixth wall” of the cooling box.
2. Thermodynamic Assumptions and Variables
To establish a performance baseline, the following parameters are used:
- Substrate: Compressed wet snow (density $\rho = 500\text{ kg/m}^3$).
- Initial Conditions: Snow temp $+1^\circ\text{C}$, liquid water content 30%.
- Target: Cooling to $0^\circ\text{C}$ and freezing 50% of the liquid water content.
- Module Dimensions: Width ($b$) = $1.5\text{ m}$, Length ($L_c$) = $5\text{ m}$.
- Cooling Medium: Liquid Nitrogen ($LN_2$) at $-196^\circ\text{C}$.
- Effective Cooling Capacity ($q_{N2}$): $\approx 300\text{ kJ/kg}$ (latent heat + sensible heat).
3. Energy Extraction Requirements ($Q_{tot}$)
The energy required depends on the target depth of the ice matrix.
Scenario A: Deep Stabilization ($20\text{ mm}$ depth)
For $1\text{ km}$ ($30\text{ m}^3$ of snow):
- Sensible heat: $31.5\text{ MJ}$
- Latent heat (freezing): $751.5\text{ MJ}$
- Total Energy ($Q_A$): $\mathbf{783\text{ kJ/m}}$
Scenario B: Surface Hardening ($7\text{ mm}$ depth)
For $1\text{ km}$ ($10.5\text{ m}^3$ of snow):
- Sensible heat: $11.0\text{ MJ}$
- Latent heat (freezing): $263.0\text{ MJ}$
- Total Energy ($Q_B$): $\mathbf{274\text{ kJ/m}}$
4. Nitrogen Consumption and Operating Cost
$$m_{N2} = \frac{Q_{tot}}{q_{N2}}$$
- Scenario A: $\approx 2\,610\text{ kg per km}$ ($\approx 3\,260\text{ liters/km}$)
- Scenario B: $\approx 913\text{ kg per km}$ ($\approx 1\,140\text{ liters/km}$)
Estimated Cost: $400\text{–}1,300\text{ USD/km}$ depending on depth and local $LN_2$ pricing.
5. Operational Speed Analysis
The speed ($v$) is determined by the heat transfer power ($P$) divided by the energy requirement per meter ($Q$).
5.1 Heat Transfer Power ($P$)
Utilizing forced convection ($h = 200\text{ W/m}^2\text{K}$) and a temperature gradient ($\Delta T = 150\text{ K}$):
$$P = h \cdot A \cdot \Delta T$$
$$P = 200 \cdot (1.5 \cdot 5) \cdot 150 = \mathbf{225\,000\text{ W (225 kW)}}$$
5.2 Speed Calculations ($v = P / Q$)
Scenario A (Deep Stabilization – 20 mm):
$$v = \frac{225\text{ kJ/s}}{783\text{ kJ/m}} \approx 0.28\text{ m/s} \approx \mathbf{1.0\text{ km/h}}$$
Scenario B (Surface Hardening – 7 mm):
$$v = \frac{225\text{ kJ/s}}{274\text{ kJ/m}} \approx 0.82\text{ m/s} \approx \mathbf{3.0\text{ km/h}}$$
Note: Increasing chamber length ($L_c$) to $10\text{ m}$ doubles these speeds to $2.0\text{ km/h}$ and $6.0\text{ km/h}$ respectively.
6. Implementation and Logistics
The unit is designed as a modular attachment for standard heavy-duty machinery (tractors or snow groomers).
- Mechanical Integration: The module interfaces with standard prime movers via standard towing hitches.
- Power Supply: Internal circulation fans are powered via the vehicle’s standard electrical or hydraulic take-offs.
- Load Management: The towing vehicle’s capacity should be matched to the $LN_2$ tank size required for the specific track length.
7. Conclusion
This mathematical proof confirms that the system is highly effective for both deep structural stabilization and rapid surface hardening. The use of forced convection ensures that cooling is delivered at industrial speeds, providing a reliable, salt-free alternative for professional winter sports and transport.
