i need some pointers on getting my rooftop glycol chiller working properly. i just took over a brewing job and don't know much about this piece of equipment.
first of all i am having trouble getting my beers down to 32/33F (the lowest i can get it down is 36F). its a G+D chiller, refrigeration was serviced on it so no leaks there. solenoid is working fine on the fermenter.
i figure a good place to start is to check the glycol:water ratio? whats the best way to do that?
i have a temperature controller on it that has a setpoint and a differential on it. i have no idea what to set them at! it was set at 27F w/ a differential of 4. i lowered the setpoint down to 25 but moved it back up after most the lines in and out of the pump and evaporator frosted up (bad?)
could someone point me in the right direction to start and figure things out?
thanks
