2/3 HP Black Glycol XL Chiller

Description

Item Description

Our Glycol XL line has a significantly larger reservoirs than our standard line. The XL line also offers chillers with higher cooling capacities.

These glycol chillers are suitable for applications down to about 5F depending on the heat load. The built in controller maintains the glycols temperature at its set point. This makes it ideal for the brewing market, along with many other low temperature applications. By adding a submersible pump, chilled glycol can be pumped out to equipment requiring cooling. Our XL chillers can also be used as a typical laboratory bath chillers as well.

Depending on application (desired operating temp/freeze point) you can use any combination of water to glycol mix ratio that you prefer. It’s a standard practise for brewing applications to use a 33% to 50% glycol to water mix ratio. During testing we used a 60/40 glycol to water mix ratio to temperatures as low as negative -14F without any freezing issues. It’s our recommendation to use a 60/40 glycol to water mix ratio due to ease of calculating the mix and the buffer it provides compared to say a 33% mix ratio which, if just a little bit off, can freeze at normal operating temperatures.

While our chillers are perfect for maintaining fermentation temps/crash cooling, its not recommended to use them for dropping wort from boiling temps. It is a common practice to either use a 2 stage system where the chiller pre-cools the water which then cools the boiling wort. You can also use water to drop the temps down to about 100F, then switch over to using the chiller. NOTE: Glycol returning to the chiller should never be allowed to reach more than 100F.

It is typical senerio to use one pump per fermenter or vessel that you wish to cool. In this type of setup, each pump used will require its own individual controller allowing for the pump to be turned off and on independently of all other pumps. The controller on the Glycol Chiller itself will regulate the glycols temperature, (for example say 28F) within that chiller. At the same time the controllers attached to each pump would regulate the temperature of that individual vessel independently by regulating the flow of 28F glycol to that vessel.

Photos for this particular 2/3 HP black Glycol Chiller show the lid with 3/8″ barbs being used. Because we’ve upgraded the design on our entire line of XL Glycol Chillers, the use of 3/8″ barbs is no longer necessary.  Each chiller now has 18 total small circular openings for running 1/2″ ID silicone tubing in addition to the power cords for the pumps.  Each XL chiller is set up to handle 8 pumps at one time. You can drill additional holes into your rear lid if additional pumps are needed however, we strongly suggest you contact us regarding the additional load on the XL chiller before doing so. Our XL Chillers can be customized to meet your load needs. Simply contact us at Support@PenguinChillers.com for more information.

Sizing a Glycol Chiller for Brewing:

These suggestions assume a decently insulated vessel (neoprene jacket or better) in a modest ambient temperature of 80F. If your setup is uninsulated, or running in hotter ambient conditions you’ll need to allow for more BTU/hr. The cold crash is figured for about 18hrs, if you want a faster crash you’ll need to add more BTU/hr. When in doubt, use the suggestions for a vessel 1-2 sizes bigger than your actual size.

• Up to 8 fermenters can be hooked up to the chiller
• Lowest recommended operation 5F (achieving these temperatures is highly dependent on application)
• 6′ power cord
• 1 year warranty
• Proudly Built in USA
