  1. Anyone running a Dragon Still?

    I can set up a chiller system the same way, in modules. It does take a little more on the PLC end, but like heat recovery chillers, the front end cost is often more than the customer can bear to save energy every day versus that front end cost, unless it is budgeted up front. It's a battle of explanation upon explanations as well.
  2. Mash Tun Cooling: Part Deux

    ...And temp of the cooling water! I can provide chillers using 100% water for cooling down to 35F. You can either pre-cool a reservoir of city water or make it a closed loop. Other chillers can get down to 40F water, which if you're cooling a tank of water can get to around 45F tank temperature. Put a feed valve in downstream of the chiller, bypassing the return to the tank and you can have 40F water again to the heat exchanger. Jackets chill slower, so cooling mash with city water without auxiliary cooling often becomes problematic in the summer. In Chicago, city water is cold all year round versus city water in Texas in the 80's.
  3. Anyone have experience w/ Affordable Distillery Equipment LLC??

    I have supplied chiller systems for several of Paul's projects, of which there no problems, and I continue to supply chillers to his customers.
  4. Spirit Still Cooling System

    If you are running a spirit run, your chiller should be around 3 HP. If the chiller has an internal tank (35 Gal?), perhaps if you crank down the steam if you can. The result should be cooler return temperature. If you don't have a bypass line around the upstream of the inlets to the still, you may get some cold water around the still to precool that hot return water. Depending if the reservoir inside the chiller is Open (atmospheric) or Pressurized, you may or may not be able to install a auxiliary chilled water reservoir to have as a blending tank for the return water that won't shock the compressor resulting in an eventual burnout. I have some photos of a typical set up like this, so shoot me an email and I'll send them along. Good luck. Mike G MG Thermal

    I've worked for a few chiller manufacturers, so that helps
  6. Spirit Still Cooling System

    These small chillers usually have a small reservoir to feed the internal pump. Still return water may be too high, so you may have to add an external reservoir with a separate pump and disable the chiller internal tank (it is atmospheric and water will come out the top on you). I purchase similar chillers and buy them without the internal tank.
  7. Spirit Still Cooling System

    The temperatures for this chiller operation, (20-30) read from set point of 20 to 30F are typical for brewery chillers, since this is a 1.5 HP (nominal) unit, I would say the output is going to be about 9,000 btu/hr. If you raise the output temperature to +50F, output capacity will be around 18,000 btu/hr. Help?
  8. Ice Machine / Ice Maker?

    You could get a water-cooled ice maker and use some water from your chiller for the chiller. You would be able to site it without worrying about the air discharge and also get more capacity from the refrigerant. Be careful on the size of your bin as well.
  9. Farm Distillery Floor-plan Feedback Request

    Are you going to use a chiller for cooling stills or well water? Up to 10 HP you can get chillers in 208-230/1/60, outdoor you'll need glycol mix for the chiller if you have any freeze issues. I do carry a "dry" glycol cooler to satisfy cooling in winter, popular up Northern US. Usually farm distillers don't have 3 phase power and water wells that don't satisfy the usage for distillery cooling.
  10. Spirit Still Cooling System

    Even worse, BRRR. How much heat will he need to get everything to boil...he can make lots of icicles, melting snow off the roof.
  11. Spirit Still Cooling System

    -50F? You would need a special chiller for that unless you put the chiller indoors-it'll help heat the indoors in the winter.
  12. Spirit Still Cooling System

    The chiller will pump chilled water if placed indoors, summertime you need to vent out hot air, or you can site the chiller outdoors and mix with glycol as an anti-freeze. Your chiller control can be set at 45F for all water, a mix you can go colder but remember the colder you go, the less capacity the chiller has (refrigerant has to work harder to be compressed and fed to the cooler to make the chilled water). Normally, less than 5 HP chillers are placed indoors to prevent glycol cost.
  13. Spirit Still Cooling System

    For up-Northerners, I also provide an air/glycol cooler with a circulator pump, 230/1/60, you can run manually or set up with a remote on-off for all your winter cooling (you need a small heat exchanger to transfer cooling from your cold glycol to the cold water tank). A bit large for your set up, it's a good way to save KW in the winter. About the same price as the 2 ton chiller, but gives you 6 tons of cooling in the winter. You can make VERY cold water or send the glycol to your backyard ice rink, LOL.
  14. Spirit Still Cooling System

    As far as using underground cooling or outdoor radiant cooling like underground pipes, about the best you are going to get is 55-60F water coming to your still, ok for some, when you are producing high volume, not so great. For a couple 100L stills, maybe a 2 or 3 HP chiller would do it and I would run it together with some reservoir which will take the spikes out of the cooling. If your reservoir water temp gets above 75F or so, crank down your heat (slow up). Usually one tote will do it for a setup this small. Cooling mash means more reservoir capacity, starting the totes at 50F or cooler. Set your chiller for 45F exit water to cool down the tote in off hours for quickest mash runs and keeping reservoir temp under control during your run. Let me know if I can be of any other help. P.S. A new 2 HP chiller, single phase is going to cost $7K or so, plus freight, but sometimes you can grab one used. I have some reconditioned ones, varying in size and price and new ones.

  15. Hello from NW Pa

    Welcome, Pip! I used to call on W Pa when I worked out of Buffalo- Used to see some doozy trucks off the road on I90 in the winter travelling from Buf to Erie! I you need any help on cooling systems, give me a shout. Mike G
