Our Stainless Glycol XL line is a series of 4 chillers made with 304 stainless steel that have a significantly larger reservoirs than our standard line, the XL line also offers chillers with higher cooling capacities.  The 2 piece lid allows you to route tubing and cords through the rear section and have access to the tub through the front portion of the lid.  The rear section has 16qty 7/8″ holes to accommodate 3/8″ or 1/2″ ID silicone tubing, plastic caps are provided to plug the holes not in use.  There are 2 additional holes to run pump power cords through.

These glycol chillers are suitable for applications down to about 5F depending on the heat load.  This makes it ideal for the brewing market, along with many other low temperature applications.  The built in controller maintains the temperature of the glycol at the set point.  It can be used as a typical laboratory bath chiller or by using a submersible pump, chilled glycol can be pumped out to equipment requiring cooling.

Depending on application (desired operating temp/freeze point) you can use any combination of water/glycol you prefer.  It’s typical for brewing applications to use about 33-50% glycol to water.  On our testing down to -14F we used a 50/50 mix without any freezing issues.  It’s our recommendation to use a 50/50 mix due to ease of calculating the mix and the buffer it provides compared to 33% mix which if off just a little bit can freeze at normal operating temperatures.

Intended for maintaining fermentation temps/crash cooling.  Not recommended for dropping wort from boiling temps.  It is common practice to either use a 2 stage system where the chiller pre-cools tap water that then cools the boiling wort, or tap water is used first to drop the temps down to about 100F, then switch over to using the chiller.  Glycol returning to the chiller should never be allowed to reach more than 100F.

It is typical to use one pump per fermenter or vessel you wish to cool.  In this type of setup each pump requires an individual controller to turn each pump on/off independently. The controller on the Glycol Chiller will regulate the temperature of the glycol (for example 28F), the controllers on the pumps would regulate the temperature of each vessel independently by regulating the flow of 28F glycol to that vessel.  Each chiller in the Glycol XL line has through lid holes for running either 3/8″ ID or 1/2″ ID silicone tubing, along with the power cords for the pumps.  The each chiller is setup to handle 8 pumps, you can drill additional holes if additional pumps are required.  Caps are supplied to seal off unused holes.
