Summary
This cooling system offers three different cooling levels and a timer that automatically turns it off for safe and comfortable use. It’s easy to move around thanks to its locking wheels, and it plugs into any standard outlet. Built with durable stainless steel and effective insulation, it’s both energy-efficient and can withstand light rain or splashes.
The Do Hiemon Box is a portable cooling booth designed to quickly relieve people from dangerously high temperatures. Created by TRUSCO Nakayama and Sanden Retail Systems, it works much like a Japanese vending machine. Inside, the temperature stays around 15°C (59°F), and cool air – chilled to 5°C (41°F) – is directed at the user’s head, neck, and shoulders. This focused cooling can help someone recover from heat exhaustion in about 10 minutes.
Quickly cooling someone down after they’ve been overheated can be risky to their health. To address this, the team designed the cooling booth with three different cooling settings and a timer that automatically turns it off after 20 minutes. This allows the body to adjust to the temperature change gradually before the person goes back out into the heat. The booth is two meters tall and built with durable, water-resistant stainless steel, plus polystyrene insulation to keep the cooling efficient.
Recent extreme heat waves, particularly in Japan where over 100,000 people needed hospital treatment for heatstroke in one season, are driving the need for stronger cooling solutions. This surge in heat-related illnesses has led cities and businesses to quickly find ways to protect people, with some even offering free public cooling stations – like the one donated to Maebashi City Hall – during work hours for those most at risk.
Designed mainly for workspaces where regular air conditioning isn’t effective, this portable booth is easy to move with its locking wheels and doesn’t need professional installation. It plugs into any standard outlet and uses about half the electricity of a typical industrial cooler. The basic model costs 1.5 million yen (before tax) and runs for just 16 yen per hour. Customers can also add options like lifting hooks or portable power sources, making it useful on construction sites or at outdoor events even without access to traditional power.
