Dual evap single stage

[ibm390s]

This is a small worklog for a dual evap single stage.

hardware

20000BTU Rotary
2.8Kw Condenser
2 evaps made by piotrek
3 pressure sensors
3 solenoid valves for liquid and saturated gas control
1 Unitronics v280 (http://www.unitronics.com/Series.aspx?page=vision280) PLC with several extension modules for data aquisition from the pressure sensors and PT temp sensors. Touchscreen and Ethernet port for data logging via ModBUS

we hope that this setup will hold 500W at -45.
This single stage will cool the skulltrail in bench sessions (when i run out of LN2)

ditto. :p so i had to hit google and find out more about this... is this something like phase change (http://www.overclockingwiki.org/index.php?title=Extreme_cooling#Phase_change)?
looks like it's going to be awesome temps. :)

it is phase change,and it is a dual evap,to cool a skulltrail
