The Therminator™ is the fastest way to chill your wort to yeast pitching temperature and get your fermentation off to a quick, bacteria-free start.
- All 316 stainless steel plates and fittings.
- Chill like the pro's - Identical to commercial brewery chillers.
- Brazed together with pure copper in an oxygen free furnace- no potential leaks like a gasketed unit.
- Chill 10 gal in 5 min to 68oF using 58oF cooling water at 5 gpm.
- Great for southern climates. (see notes on "Performance" page)
- Ultra compact (7.5" W, 4" D, 3" H)
- Super low restriction - ideal for gravity feed.
- Easy to clean and sanitize - small enough to boil.
- Garden hose thread connections on water side - no extra adapters to buy.
- 1/2" male NPT fittings on wort side mates up with virtually all common hose connector types. Easier to sanitize than female fittings.
- Saves water - lowest water consumption on the market.
- Comes with heavy gauge stainless mounting bracket.
How to use this graph:
This graph is used to predict the gallons per minute (gpm) of wort you'll be able to chill from boiling down to 68oF (ideal fermentation start temp) using water from your garden hose as the cooling media.
1) Measure the cooling water flow rate in your brewery using a bucket of known volume and a stop-watch (gal/min). Then measure the cooling water temperature using an accurate thermometer.
2) Choose either the blue (5.0 gpm), cyan (3.0 gpm), or green (2.0 gpm) line that best matches your cooling water flow rate. If your flow lies between these lines, it is acceptable to interpolate between them.
3) Go to the point on the Y axis labeled "Cooling Water Temp (F)" to your cooling water temperature measured in step (1).
4) Draw a horizontal line to intersect the cooling water flow rate line you selected previously (Blue, Cyan or Green) in step (2)
5) Draw a vertical line at the intersection point down to the X axis labeled "Wort Flow (gpm) and read the wort chill flow rate you'll get at your brewery!
Example: If you have 58F cooling water and 5 GPM of flow, draw a horizontal line (see dark line in graph above) at 58F over to the blue line. Draw a vertical line (see dark line in graph above) from the intersection point down to the X-axis and read 2.0 GPM.
Notes for Southern Climates: - see FAQ tab
Let's face it, if you've got ice cold cooling water and high flow rates, it's a short punt to design a cooler to get the job done. The brewer's reality: fall, spring and summer bring higher ground water temperatures and brewers struggle cooling wort to acceptable levels. For ales, if you can't chill to 68o
F, your fermentations will produce higher levels of esters, fusels and other compounds that you may not want in your beer (except for those esoteric Belgians!). For lagers, the effect is even more pronounced.
At Blichmann Engineering, they've leveraged 20 years of Engineering experience designing cooling systems, and coupled it with 17 years of homebrewing experience to develop the TherminatorTM. The result is a chiller that works well all year long. Not only did they provide raw cooling horsepower, they also provided the things brewers want:
- broad operating range at fast cooling rates
- low water usage (high efficiency)
- low restriction for gravity feed at high flow rates
- compact size for easy use and sanitation
- heavy duty mounting brackets for simple installation
- convenient straight-through water connections to prevent kinked hoses
- resistance to plugging
- substantial reduction in ice usage for chilling below cooling water temps
Blichmann tested and analyzed the competition at their facility using precision thermometers, flow meters, and a cooling water blending module for precise control. The results? The Therminator is the best overall value and still the king of coolers!
How do I cool my wort with high ground water temps?
The wort cannot be cooled below the cooling water temperature. While the Therminator is the highest capacity homebrew chiller on the market it'll get you within a few degrees of your cooling water. But if you live in a warm climate area, that may not be enough. To drop below your ground water temp you will need to use a cooling water pri-chiller. THis is simply a 5.8" copper coil (25-50ft) immersed in a pail of ice water. Use this to cool the grouns water BEFORE it enters the chiller. Stirring the ice water is recommended.
