Hi guys!

To get some stuff out of my flat I built a nice new Singlestage optimized for hot summer days (tests were done with 27°C ambient and the NL11F stayed cool and always under 15.8 barg HD).

Also I added a resettable fuse to the front panel which triggers when the compressor blocks due to a too high pressure differential. Usually at some time the internal safety of the NL11 triggers but you have to wait for 10-15 minutes to turn on the compressor again. So now you only have to wait 2-3 minutes until the pressure equalizes and after pushing the fuse back in you can start the unit.

Caooling capacity is nice, with the high ambient setup I lost a few degrees down there but hey, I cant have everything...
