Mirai Intex introduces air-cycle plasma freezing system for medical applications

Mirai Intex has unveiled a new plasma freezing system designed to enhance speed, quality, and efficiency in blood plasma processing. The system employs air as the refrigerant and aims to replace traditional technologies reliant on synthetic or hazardous gases.

According to the company, the MIRAI X CRYO 20 and MIRAI XM CRYO 20 models can crystallize 300 liters of plasma in 40 minutes, completing the full freezing cycle in 6.5 hours. Conventional systems typically require 90 to 120 minutes for the same crystallization volume. Mirai states that its rapid and uniform freezing process helps preserve protein structure and clotting factor activity, ensuring high biological quality.

The technology operates without freons, ammonia, CO₂, or other refrigerants, relying instead on ambient air. Mirai claims this approach lowers energy consumption by up to 15% compared to legacy systems and eliminates the need for refrigerant disposal or leak monitoring. The system is also designed for minimal maintenance, with no filters, parts, or fluids requiring regular replacement.

Additional features include compact design, low noise and vibration levels, remote monitoring, and automatic restart capabilities. The units do not require defrosting, as the closed-cycle air system prevents ice buildup inside the cooling chamber.

According to Mirai, the system can perform up to 15 freezing cycles in five days under continuous 24/5 operation—approximately 30% more than earlier-generation machines. This allows users to increase productivity without expanding floor space or staff.

“Rapid crystallization preserves molecular structure. The entire plasma volume freezes simultaneously and uniformly,” the company noted.
