Re: Introductions forum
Hello,
I am a Chief Engineer working on a 270' factory trawler in the Bering Sea, Alaska. I found this sight while searching for more information on superheat and the adjustment or monitoring of it. There is a lot of great information here. Makes a guy really think. We use a flooded R22 system to freeze around 130 metric tons of fish per day. If anyone has a good way of setting superheat on a flooded horizontal plate freezer, please let me know. I am running liquid into the freezer through a Danfoss REG 25 valve @45 psi and 4mm orifices into the liquid lines for each plate, suction pressure is the equivalent of -35^f and the suction temp is -32^f. We are getting good core temps on the blocks of around -26^f after 104 minutes. I would like to know if I am close to max efficiency for this type of setup.
Thanks for your help with this.......
