  1. Around 50F supply. Control valves to set flow for each. Depending on the size of the condenser- smaller ones have a higher leaving- 120F or more. Larger sized for 95F leaving.
  2. Especially when you get down to cooling equipment and you've run out of cash. I've been using them for customers that want add-ons that are energy savers for paybacks that will pay for the add-on.
  3. We sprayed on foam then spray painted white before shipping this along with the chiller (which is on the roof). One pump is visible - there is another and the control panel on the opposite view. 40 HP chiller + 2500 Gal chilled water reservoir.
  4. Customer did a custom paint job on his pump/tank:)
  5. Just did a large distillery mash cooling selection- Using a 60 Ton chiller with a two fan EMSCO glycooler vs a 100 Ton chiller is about $10,000 more on equipment but saves 37 Kw per hour energy during operation, less than one year payback. This installation will be in the sweltering SE USA, but if I used it in the N. USA, savings would be close to 50 Kw per hr or more. Using just a straight drycooler saves 15 Kw per hour on a 20T. system during all close to 35F operation in Utah where water is scarce. 214-0022-VIRGA_III_Vs_TAC_Comparison_Chart_WEB.pdf
  6. I have that small air cooler that can provide cooling for the mash coil, 230/1/60, comes complete with pump. two sizes- 6 and 12 ton. If air temp is too warm, you can finish with city water or small chiller. Mike G.
  7. Still trying to get out to N. AR to look at some property this spring, but housemate and I have been battling health issues- she was hospitalized 3 times in Feb, the last time she was being seen by FOUR Drs. from the CDC! And they say it's just a FLU!!! She had IV's with 6 antibiotics and two different types of pneumonia. They never tell you what you had, only what you don't have! Atlanta is a cesspool for mystery diseases, why we want out!
  8. One size fits all>>>> Chiller+ reservoir+ process pump (chiller has its own pump). Chiller GPM always larger than process GPM.
  9. For just still condenser cooling, an adjustable water valve (spring loaded ones or electronic) meters amount of water into condenser fro the chilled water main header and bypasses the remainder to temper the return water to the chiller. Or you can set a water valve downstream of the chiller to bypass some of the water/glycol return to temper return fluid before returning to chiller. Chiller pump flow without a reservoir should beat least double the flow required by still. Since most distilleries are crashing and doing a still run the same day, chiller tank will be coldest at days start, then lose some ground before making the still run, which is ok, since still doesn't need as cold a cooling medium. Similar to beer crashing, you can install a air/glycol subcooler to cool return glycol before returning back to cooling tank. Lot of this has effect on the budget, so some thought should be given to future plans on expansion.
  10. That's why I like to offer the glycol coolers to customers in the North, I have guys in ME, VT and CT not even turning the chiller on from NOV-MAR. For Thatch's case, probably save 3-5 HP/hr every day all winter.
  11. Welcome! I have clients using chillers around San Diego and do not have glycol in their systems. The purposes for glycol are twofold- to keep the process fluid from freezing below ambient temps below 0F and to sanitize if the process fluid is open to the atmosphere (reservoir tank) to reduce organisms (glycol mixture must be above 30%). If you don't go below freezing then you can treat water with chemicals or use ozone treatment (which is popular in Cali. I recommend Ozone Systems which are made in CA. I have larger systems that use glycol and can do so except for the worry of a leak (and a messy cleanup). If you are cooling mash, you will need an auxiliary tank, if only the still condenser, I have a couple chiller types that have integral tanks and are non-atmospheric that you can use city water. Email if you need specs, descriptions, or referrals. Mike Gronski, MG Thermal 770-995-4066
  12. You could run water through a dry cooler as well. I use them with chillers as winter operation for glycol cooling...saves on the power of running the chiller up North, but you could use them to take out heat of water as well.
