IceMaster G20 - Glycol Chiller - Digital Fermentation Control - (with 2 integrated pumps for dual temp)

Item is in stock Hurry, Only 3 Left! Item is out of stock Item is unavailable

From Kegland:

The Icemaster G20 is an efficient glycol chiller that has fantastic cooling performance. It's compact, quiet and ideal for a domestic environment.  It is powerful enough to chill well-insulated fermenters up to 300L in size or multiple smaller fermenters.  It has about 600-watt cooling power making it suitable for crash chilling even in hot ambient temperatures in your garage or brewery. 

NOTE: The castor wheels and dolly in the photos are not included.

To get the most out of this unit we recommend the use of Propylene Glycol (ideally about 30% concentration). 

IceMaster G20 Instruction Manual


  • Refrigerant: r600a isobutane
  • Cooling Power: 600watts (0.8HP)
  • Power Consumption: 155w
  • Tank: 16.42L 
  • Max Head (per pump): 5meter
  • Max Flow (per pump): 600L/Hr
  • Output Barb Size: To suit 10mm (or slightly smaller) ID tube, Barbs are 10mm. 

Integrated Pumps

Unlike other units, this unit comes with 2 integrated pumps and temp controllers.  This will allow you to independently cool two fermenters at the same time at different temperatures.  Set the temp on the main reservoir to -4C then (after you have added 30% glycol) then on the other side of the G20 set the other two temperatures to your ideal fermentation temperatures.  No additional wiring necessary.  Pumps included and already wired up ready to use.

Chill Wort

Cooling wort from 100C to 50C is quite easy with tap water most of the time.  With that said cooling from 50C to 18C can take ages.  This is because your tap water might be as hot as 35C meaning it would be impossible to mater how much water you use to get down to 18C (yeast pitching temperatures).  The Icemaster G20 solves this problem and is the easy way to take advantage of sub-zero glycol to cool your fermenter to acceptable temperatures for the fermentation process (PLEASE NOTE: only use this unit to chill wort after you have already chilled down to <50c with water, otherwise there is a risk of overloading the compressor). This unit can be used in conjunction with an coil immersion chiller, Fermzilla temp twister or plate chiller

Cool Your Bright Tank Fermenter

Larger and well-insulated fermenters, in particular, will often generate enough heat to heat the fermenter which is why large commercial breweries often have no heating.  They rely on the yeast activity to heat the fermentation tank.  The G20 can be used to cool a range of different fermentation vessels when used with products such as the Temp Twister.


The KegLand G20 IceMaster glycol chiller can also be set up to heat the reservoir. There is a push in port on the two temperature controllers to control the heating of the device you decide to use.

Sorry we don't stock any submersible heaters for this application.  Please note: Installation of such heating device must be installed by a trained electrician.

Compressor NOT Thermoelectric

Although thermoelectric glycol units are significantly cheaper to make to really get the power needed to chill wort quickly and efficiently you need compressor cooling.  Compressors increase the cost of the manufacturing process however due to the fact they are between 3-6 times more electrically efficient for this application the initial manufacturing cost will easily be recouped in electrical savings.  In addition to this compressors are significantly more powerful and able to pump more heat even in hot ambient temperatures where thermoelectric units will struggle.  So if you want to retain the ability to crash chill fermenter you can't go past the cooling power of compressor cooling.

Installation Requirements

This unit requires a 100mm Clearance around all air vents.

Regular maintenance of dust around radiator is required to ensure optimum efficiency.

Ideally used with Glycol/Water ratio of 20% to achieve -8°C freezing point

Brewing frequently asked questions

How long does it take to brew beer?

The time it takes to brew beer can vary, but on average, the process takes about 4 to 6 weeks. This includes the various stages such as malting, mashing, boiling, fermenting, conditioning, and bottling. However, some beer styles may require longer aging periods for optimal flavor development.

Is home brewing worth it?

Many people find home brewing to be a rewarding and enjoyable hobby, allowing them to create unique and customised beers. It provides a deeper understanding of the brewing process and offers the opportunity to experiment with different ingredients and styles. Additionally, home brewing can be cost-effective in the long run compared to purchasing craft beers. However, it requires time, effort, and a certain level of commitment. Whether it's worth it ultimately depends on one's passion for brewing and the satisfaction derived from the process and the end product.

Is home brewing legal?

Home brewing for personal use is generally legal, and there is no need for a specific license as long as certain conditions are met. Home brewers are allowed to produce beer, wine, and cider for personal consumption. However, there are limits on the amount that can be brewed without a license. As of January 2022, the limits were 100 litres for beer and 100 litres for wine per household.

It's important to stay informed about any updates or changes in the regulations, so it's advisable to check with local authorities or brewing associations for the most current information regarding home brewing laws in the UK. Always ensure that you comply with the relevant regulations and guidelines to enjoy home brewing within the legal framework.
