This will have to be built inside a water proof box, with a radiator/other provisions for dealing with heat.
All valves are line power – 110V or 3 phase, the pump is three phase
There will have to be manual override switches, usually with an “Off/On/Auto” feature, for all functions. We can send you our current box, with a Unitronics M 90 in it, if needed, but we think it would be better if you start from scratch.
The thermocouple inside the pasteurizer uses thermostatic wire, and is a:
Pyromation Thermosensor Model:KP43G09M/2 T163
Pyromation, Ft. Wayne, IN.

Reads 2˚ high at 51˚. May have an issue, or it may be in the Unitronics. Will need to be able to calibrate the thermocouple to read correctly.
“A” cycle
1. Open Hot Valves
2. Start Glycol Pump
3. Heat to X˚ F
a. If it does not change rapidly in temperature
i. Sound alarm
ii. Open all valves (this is to clear any air pockets which may have formed)
iii. Close all valves, except hot
4. Hold for Y minutes at X˚ F
5. Stop Glycol Pump
6. Close hot valves
7. Open City Water Tap
8. Open city water valves
9. Start Glycol Pump
10. Chill to 100˚F
a. If it does not change rapidly in temperature
