cattabriga pasteuriser

[doormaster2008]

Hi. Has anyone any experience with the PSK KEL-1 35/65/125 Pasteuriser. When it's pulling temperature from 85c to 04c it works perfect until it gets to 14c then starts cycling on lp switch.What should this be set at as it'scutting off at 20psi . It runs on R404a. This then takes in total about 4hrs for its cycle instead of about 1.5hrs. Thanks

Hi Martin. No. I've checked the level and that's nearly full. Should it be drained and filled with fresh every so often.

you need to check the freezing point as if its to week it freezes and will trip on LP

Hi Martin. Thanks for your help. Just found out they have filled it with neat antifreeze. I have ordered foodsafe glycol ready mixed to 22% giving protection to -10.which should be OK.
