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

Upgraded 500W glycol chiller with dual independent temperature control. The Jointech G20.2 features improved pumps, dry-break connections and a reinforced sight glass for cleaner, more reliable operation.

The Icemaster G20.2 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 500-watt cooling power making it suitable for crash chilling even in hot ambient temperatures in your garage or brewery.

What’s New – G20.2 Upgrades

The G20.2 introduces several key improvements over the previous model, focused on reducing mess, improving durability and increasing performance:

Jointech Dry-Break Connections

Upgraded to Jointech quick-connect dry-break fittings
Prevents glycol spills when disconnecting lines
Faster, cleaner connection and disconnection
Ideal for multi-fermenter setups or frequent changes

Improved Sight Glass Design

New push-in sight glass with stabilising bracket
More secure and resistant to movement or damage
Easier to monitor glycol levels at a glance
Improved durability compared to previous design

Stronger, Upgraded Pumps

Enhanced pump performance for improved flow and pressure
Better suited to longer line runs and multiple fermenters
More consistent cooling performance across setups
Increased reliability during extended operation

These upgrades make the G20.2 noticeably easier to live with, particularly in busy or multi-vessel brewing environments.

Integrated Pumps
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.

Chilling Wort

Cooling wort from 100°C down to around 50°C is usually straightforward using mains water. However, getting from 50°C down to typical yeast pitching temperatures (around 18°C) can take significantly longer.

In the UK, mains water temperatures can often sit between 10–15°C in winter, but rise to 18–22°C in summer. This means that during warmer periods, it becomes difficult — and sometimes impossible — to chill wort down to pitching temperature using tap water alone.

The Icemaster G20 solves this by using sub-zero glycol to complete the chilling process, allowing you to quickly bring your wort down to a suitable fermentation temperature regardless of seasonal water temperatures.

Please note: This unit should only be used after initial chilling with water (below 50°C). Using it at higher temperatures may overload the compressor.

This unit can be used in conjunction with all these chiller options:
a) TMM Immersion Chiller

b) BrewZilla 35L Chiller

d) Plate Chiller

Heating
The KegLand G20.2 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.

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 3-6times 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 maitenence of dust around radiator is required to ensure optimum efficiency.
