Typical performance


This cooling curve is the typical characteristic of internal temperature at empty cabinet, not guaranteed value. Note that cooling performance depends on heat mass and arrangement of contents strongly.

Your Industries


Maintaining the safety and quality of products is the most important in the pharmaceutical industry. Precise temperature control during delivery is required to keep good quality, especially for vaccine and some biopharmaceuticals.




No special freezer/ refrigerated trucks are required. FPSC make possible freezing/refrigerating transportation, once connected to DC power supply.



– State of the Art

FPSC, Free Piston Stirling Coolers, are the complete CFC free system, using natural He gas.
It is small, portable, and it is widely used for precise temperature control for under -50℃.
Twinbird succeeded in mass production through the collaborative network of craftsmanship in Tsubame-Sanjo.
