Winery chillers used in the fermentation process of wine making to control the temperature during fermentation. Glycol fluid temperatures vary based on the type of wine being made and the preferences of each wine maker, but most winery chillers will operate in the range of 35F to 50F degrees (for wine vessel temperatures of 45F to 60F degrees).
1.5 to 50 Nominal tons.
Packaged (with tank and pump) Most wine makers order their glycol chillers for outdoors in a package (all in one) type design.
Modular (no tank or pump) Modular winery chillers may be used when the winery already has a tank and pump or if the existing chiller is not adequate to keep up with the capacity of the current system, a modular unit can be added as a booster chiller.
Split (indoor chiller with outdoor condensing unit) Split chillers may be desired if the chiller unit is located on the roof. By splitting the tank/pump/heat exchanger in a separate cabinet, it can be located indoors or at a location where it is easier to access.
Amchill Winery Chillers are Available in single phase power for sizes above 5 ton when 3 phase power not available.
Note – American Chillers brand winery glycol chillers ship with remote control panels that can be installed indoors in a convenient location so the wine maker can easily control and monitor the chiller.
All Heat exchangers experience a capacity loss when the fluid is a higher specific gravity than water. Glycols are heavy, syrup like fluids at full concentration, and become thinner when mixed with water. However, the mixed solution of water-glycol will be thicker, heavier, than the water alone was. Thus, to achieve the same heat exchange inside the heat exchanger , requires more surface area or a larger heat exchanger. American Chillers heat exchangers are engineered for full rated capacity with the use of 30% glycol solutions. Our heat exchangers start out with 30% more surface area capacity than the heat exchangers used by other manufacturers so you still have full capacity with 30% water-glycol solutions. If you are using glycol concentrations above 30%, consult factory prior to purchasing your chiller for chiller selection assistance.

American Chillers & Cooling Tower Systems, Inc. recommends propylene based glycols because of their non-hazardous nature and as such, we must be aware of the effects on the standard refrigeration heat exchangers and pumps. A 40% solution of propylene glycol will reduce the chiller heat exchanger’s ability to chill by at least 7.2%. We know from experience, that some heat exchangers chilling abilities is reduced by 20%. This means the chiller with a 10 ton capacity for chilling water will have a capacity between 8 tons and 9.3 tons with 40% PG. Most American Chillers have heat exchangers large enough to handle 30% PG without loss of capacity due to our “value-added” engineering practices. We can easily provide a chiller heat exchanger for even 50% PG at the customer request at time of order.
1. All parts are guaranteed to be free of defects in material and workmanship for 12months from date of original purchase.
2. Scroll compressors are guaranteed to be free of defects in material and workmanship for 60 months from date of purchase.
3. Labor: during the first 30 days after startup, American Chillers will reimburse the owner for any reasonable labor charges incurred for the replacement of a warranted part, according to the rate schedule. A time allowance of 30 minutes, for one technician is allowed for the diagnosing of a malfunction. Consult customer service for the labor rate schedule .
4. During the first 30 days after startup, American Chillers will pay for regular, ground shipping of any covered part shipped to the customer. Express shipping and air freight charges are the responsibility of the customer. After 30 days, the customer is responsible for shipping defective parts back for credit and for the shipping charges from American Chillers to the customer.
What is not covered:
1. shipping costs after the initial 30 days. Express shipping charges over regular ground charges are not covered.
