Extreme Cold Weather Tents for The Winter Olympics

At minus 20 °C, prefabricated tents act as “mobile fortresses” to ensure the safety and functionality of large-scale events. These tents provide two key services: quick security checks for people and vehicles, and temperature control to protect sensitive equipment. This “breathing cold guard” helps events run smoothly even in extreme cold.

For the Winter Olympics, organizers set up a 50-meter long security checkpoint using these cold-weather tents in just two hours. Despite -25°C winds, the double-layer tarpaulin with built-in rock wool kept the inside at a comfortable 5°C. The top infrared heaters melted snow automatically, and non-slip mats on the ground allowed 200 people to pass through every minute.

Integrated millimeter-wave body scanners and license plate recognition systems maintained 99.8% accuracy in low temperatures. One driver remarked, “Last year in Russia, open-air security checks almost froze our fingers. Here, it feels like getting into bed!”

Next to the downhill course, thermal tents created “safety pods” for timing sensors and snowmaking equipment. Built-in air conditioning and electric heating films kept the temperature at a steady 25°C, preventing electronic failures. Moisture-proof aluminum foil and dehumidifiers controlled humidity below 40%, while small diesel generators provided backup power for four hours.

German snow machine manufacturers found that equipment worked continuously for 72 hours without issues in the tent, compared to needing defrosting every three hours outdoors.

During a snowstorm with 23m/s winds (Force 8) and 30cm of snow, computer simulations showed minimal deformation of the aluminum frame, well below industry safety limits. A nanocoating on the tarpaulin prevented snow from sticking, and pressure pulses shook off accumulated snow every 15 minutes. Even with partial damage, tarpaulin modules could be replaced in just 20 minutes.

Post-event data confirmed zero equipment failures and 100% efficiency in security channels during the storm. From mobile security stations to thermostatic equipment cabins, these prefabricated canopies use technology to tackle safety and efficiency challenges in extreme cold.

They are not only invisible guardians of ice and snow events but also showcase human ingenuity in expanding activity boundaries in harsh climates. After the Olympics, these detachable “cold fortresses” were shipped to Arctic research stations, ready for new challenges.
