Glycol Systems

For winemakers dedicated to crafting consistently exceptional wines, precise temperature control during fermentation and storage is paramount. Investing in a complete glycol chilling system offers unparalleled reliability and the ability to independently manage the temperature of your fermentation vessels, storage tanks, and even your cellar – all with a single, efficient unit.

The Science Behind the Chill: How Glycol Systems Work

At the core of this technology lies the glycol chiller, a specialized refrigeration system designed to cool a reservoir of propylene glycol, often simply referred to as "glycol." This chilled glycol solution is then circulated through an insulated network of tubing connected to the chiller's inlet and outlet. This forms your primary cooling loop. To cool individual vessels, you simply connect their heat exchangers (such as tank jackets, stainless steel plate exchangers, or stainless steel cooling snakes) to this main loop. Once connected, the chilled glycol flows through the heat exchanger, effectively cooling the wine within the vessel.

Fine-Tuning Your Fermentation: Mastering Temperature Control

Given that glycol is typically chilled below water's freezing point for optimal cooling efficiency, maintaining fermentation temperatures above freezing requires careful management of the glycol flow rate through the heat exchanger. This crucial adjustment can be achieved through two primary methods:

  • Manual Regulation: Implementing a shut-off valve allows for manual adjustment of the glycol flow, enabling temperature control. However, this method necessitates consistent monitoring to maintain the desired temperature.
  • Automated Precision: The recommended approach for effortless and effective temperature management involves utilizing a temperature-controlled solenoid valve. This system is connected to the tubing leading to the heat exchanger, with a temperature probe placed directly in the wine (often within a thermal well). Simply program your desired wine temperature, and the solenoid valve will automatically open and close as needed to maintain that precise temperature.

    34 reviews

    Built-in pumps and digital controllers Control multiple fermentation temperatures independently Fill with 20% glycol solution for optimal chilling performance Cold crash with good insulation Perfect complement to BrewBuilt X-Series Conicals The IceMaster Max 4 is designed to cool fermentations in small vessels or barrels. It can be used with any vessel/fermenter/tank/barrel that has a glycol jacket or submersed cooling snake/coil/rod. This chiller features 4 built-in submersible pumps with independent digital temperature controllers, allowing you to control the temperature of 4 separate fermentation or storage vessels at once. Each digital controller includes a thermal probe that should be inserted into a thermal well in your vessel or can be taped to the outside of the vessel if you don't have a thermal well. The digital controller then measures the temperature of your tank and turns the submersible pump on or off to cool the liquid in your vessel to the desired set temperature. Compatibility The Max 4 can be used with any fermenter that has a built-in cooling jacket or a submersed cooling coil. It works well as the cooling source for the following: Speidel - Speidel tanks with optional cooling jackets. Barrels - If you use our barrel snake. This can be particularly attractive for a white wine ferment in a barrel. Capacity It is always difficult to determine exactly how many tanks can be chilled at one time as it depends on what is happening in each tank, how the tank is insulated, and what the ambient temperature is. Cold stabilizing always requires the most energy and requires well insulated tanks. We are currently experimenting with capacities but can provide this rough guide to get you started. 1 - 60 Gallon Tank or Barrel 2 - 15-30 Gallon Tanks 4 - 5 to 15 Gallon Tanks Set Up In order to hook up the IceMaster to your fermenter or tank's cooling system, you will need 2 lengths of tubing. All tubing connections should be secured with hose clamps. Length 1: Barb of 1st bulkhead (IN) to cooling system outlet Length 2: Barb of 2nd bulkhead (OUT) to cooling system inlet Specifications: 4 built-in submersible pumps with independent digital controllers Pump controllers read in °F/°C Temperature controller reads in °C Labeled IN and OUT stainless bulkheads with 3/8" OD barbs Tank Capacity: 30L/8 Gal. Water Capacity Compressor: 3/8 HP Cooling Capacity: 780 Watt/2600btu/0.26 ton Refrigerant: R134a Voltage: 110V (3.6 amps) Dimensions: 16.1" x 16.1" x 26" Wheels included CE Certified Max Head: 21.3 ft (6.5 m) Warning: Do not set the reservoir temperature controller lower than 28°F (-2ºC). Running the unit below this temperature may negatively affect the unit's efficiency and has the potential to freeze beer which may impact the finished beer's flavor.

    MB® MiniChilly | Multi-Tank Glycol Chiller | Bulkhead Sets for 10 Fermenters | Digital Temp Control | Rolling Casters | Stainless Steel Enclosure | 1.2 HP

    2 reviews

    The German made 1.2 horse power MB Chiller is an ideal solution for the avid home winemaker looking to chill up to 10 fermenters at once. The idea of the MiniChilly is that for each fermenter you want to a chill a pump kit is added. A pump kit (GLY35) includes a submersible pump that is placed in the cold bath of the Mini Chilly along with a digital controller that is placed next to your fermenter. Silicone tubing is included to make the connections. The digital controller includes a thermal probe that should be inserted into a thermal well in your vessel or can be taped to the outside of the vessel if you don't have a thermal well. The digital controller then measures the temperature of your tank and turns the submersible pump on or off to cool the liquid in your vessel to the desired set temperature. In this way each tank can be set at different temperatures. The MiniChilly is made by Quantor/Kreyer of Germany who is the largest manufacturer of glycol systems for breweries and wineries in the world. Made with high quality manufacturing and components, the MiniChilly is a durable system for many years of problem-free wine making. The unit features a stainless steel case with stainless 3/8" barbs in the top that allow for a clean connection of the silicone tubing that will run from each pump to each tank. The MiniChilly is able to chill its reservoir down to 21°F when a 30% glycol solution is used. The compact size and included casters make it easy to move around the winery when needed. Applications: Cooling of fermentation and storage tanks Cooling must and wine for clearing and cold stabilization Cooling rooms and storage halls with additional fan coils Capacity: Many chiller ratings are based on the theoretical power of the compressor, while the cooling capacity of the MiniChilly is rated at a realistic ambient temperature. This is much more useful for predicting the MiniChilly’s performance in real world applications. Of course, you could cool a greater number of smaller tanks but you’re ultimately limited to the 10 connections. Actual cooling capacities will vary based on the insulation of the tank. For the examples below we assume neoprene or better. Cooling Capacity Example: Up to 10 x 110L well-insulated tanks fermenting at 68°F in 80°F ambient temperature. For every fermenter you want to cold crash remove 4 fermenting fermenters from the capacity. Set Up: In order to hook up the MiniChilly to your fermenter or tank's cooling system, you will need 4 lengths of tubing per pump. All tubing connections should be secured with hose clamps. Length 1: Submersible pump outlet to inner barb of 1st bulkhead Length 2: Outer barb of 1st bulkhead to cooling system inlet Length 3: Cooling system outlet to outer barb of 2nd bulkhead Length 4: Inner barb of 2nd bulkhead to MiniChilly reservoir (should drain freely, no connection necessary) Technical Characteristics: Power: 110V-1Ph/50-60Hz Compressor Power: 1.2hp/900watts Cooling Capacity at 32°F glycol temp and 90°F Ambient Temp: 1.05 KW/1050 Watts (60Hz 110V) Cooling Capacity at 60°F glycol temp and 90°F Ambient Temp: 1.92 KW/1920 Watts (60Hz 110V) Stainless Steel Unit Water Temperature Range: 21°F - 86°F (-6°C - 30°C) Ambient Temperature Range: 50°F - 90°F (10°C - 32°C) Refrigerant R134a Free Glycol Water-Bath for Mini-Pumps Fittings 3/8" for Plastic Tubes of Individual Pumps Solid Wheels w/ Breaks for Easy Mobility Universal C19 Plug On/Off Switch Water-Level Sight-Tube Grooves for Individual Pump Cables Safety Inner Separation Water Side from Electric Side Tank Capacity: 12.68 gal.
