I recently got a Icemaster Max 2 and now have three batches done with it. Here are the Pros and Cons from what I have seen as a new glycol chiller user:
Pro:
- Holds temps really well, like any temp you want (with my Spike CF5 and neoprene insulator)
- I have hot tap water (SW US) most of the year, so being to drop the fermenter from 85+F to 65F for pitching in less than an hour is fantastic
- Does not leak and the included sight glass is great to know the tank glycol level
- Tank holds temps as low as 25F without much trouble or 'work'
- Temp stability is great *IF* the glycol tank is kept within 20 degrees F of the desired fermenter temp (big learning point)
- Quiet enough that I don't really notice it much
- I can legitimately lager with it
Cons:
- As said above, the instructions were not just abysmal, MoreBeer posted the wrong ones to their website--steep and leaky learning curve as a result
- Controllers only work in Celsius (not a big deal in my view)
- (Not particular to this unit) temp stability was awful when I set the glycol tank to 25F and tried to maintain the fermenter at 65F--huge swings resulted; instructions did not say to do this, but DO set the glycol tank temp to ~15-20F below the desired fermenter temp, no lower
- Glycol tank controller is on the backside, and I keep it in a room's corner, meaning I am constantly pulling the unit away from the wall and resetting the tank looking at it upside down (reason is the Con above)--I wish the three controllers were all on one side together
