SC-UG08S / FPSC Module UG08S

Key Features

Achieve 25 watts of cooling capacity at -80℃

  • The SC-UG08S is a standard cooler, which is suitable for strict temperature control below - 80 ° C. Depending on the heat mass and temperature of object, cooling capacity and speed can be fine-tuned.

Compact and lightweight standard type

  • SC-UG08S can be installed on various applications, especially for portable type equipment because of its compactness and lightweight.

Drive PCB and fan are integrated

  • All of the cooler, Drive PCB and fan is integrated one unit. You can install SC-UG08S into your equipment as it is.

"Vibration detector" protection

  • “Vibration detector” on SC-UG08S automatically reduces the output instruction to suppress the abnormal vibration.

Typical performance


This cooling curve is the typical characteristic at no load, not guaranteed value. Note that cooling performance depends on each design of cooling system strongly. Referring user's manual at our web-site, and confirm if our products are suitable for your use.

New Function “Original Vibration suppression Technology”


1.Abnormal vibration Abnormal vibration with noise occurs in “(1) when cooling a large thermal load” or “(2) when a large thermal fluctuation occurs in the object to be cooled”.


2."Vibration detector" protection DRIVE PCB suppresses and is idle FPSC operation forcibly when abnormal vibration is detected. After abnormal vibration with noise stops, DRIVE PCB starts to drive FPSC again.

※We also have products without a vibration detector. Please contact the SC Division for details.

Your Industries


Low temperature synthetic reaction tests in the field of pharmaceutical intermediates and fine chemical fields are effective in suppressing the formation of byproducts.

Freeze Drying

FPSC is used for tests for highly controlled freeze-drying process of medical materials.

Accurate ultra-low temperature

FPSC accurate ultra-low temperature supports professional applications such as temperature calibration and inspection of electronic components .


FPSC is used for advanced cryopreservation for cells and biological samples. Precise temperature and high cooling speed are required for optimum temperature profile in freezing process.



– 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.
