This paper shows the progress made during development of "HOT" cryocooler prototypes, and engineering preproduction series cryocoolers working at the FPA temperature range of 130 - 200K. Three different cryocooler models based on rotary & linear design concepts are presented below. The progress with development of electronic control modules providing minimized regulated power consumption is also shown.
