It's a rebadged FPSC from here

        http://fpsc.twinbird.jp/en/home_e.html

They have a whole range of models.

That one uses their SC-TC04 (I think)
Basic data sheet here

Pretty glossy here incl shows use in a fan ventilated module

MUCH dearer than a Peltier cooler and much more efficient and capable 
of much greater differentials.

Their graphs show it cooling to -50 C BUT it's capable of much lower 
than that at reduced refrigeration power levels.



The company is working in conjunction with Stirling guru David 
Berkowitz, who has been playing with Stirling engines and coolers for 
decades.
