Small amounts can extract a large amount of heat! A new ground freezing method that takes the Earth environment into consideration.
"ICECRETE" is a new ground freezing method that contributes to the mitigation of global warming by using natural refrigerants. By utilizing liquefied carbon dioxide (CO2) as a secondary refrigerant, the latent heat of vaporization of the liquefied carbon dioxide can be harnessed, allowing for cooling temperatures to be set as low as -45°C, compared to the -30°C limit of conventional brine. Additionally, it can shorten the overall construction period, including piping work. 【Features】 ■ Environmentally friendly ■ Capable of extracting a large amount of heat with a small quantity ■ Low power consumption ■ Realizes compact and lightweight piping ■ Possible reduction of construction period *For more details, please refer to the PDF document or feel free to contact us.
