IceMaster G40 with 4 Submersible Pumps – Glycol Chiller – Digital Fermentation Control

Compact multi-fermenter chilling solution which offers high performance for homebrewers and small volume breweries.

This glycol chiller / ice bank comes as standard with 4 built-in submersible pumps each with independent digital controllers allowing the optimum fermentation or cold crash temperature to be set for up to four fermenters or brite tanks.

This chiller is ideal for temperature control of vessels which have a thick insulated jacket. It is powerful enough to chill 4 well-insulated 60L FermZilla All Rounders or 58L Kegmenters with Temp Twisters.

It has a cooling capacity of about 780W or 1HP making it suitable for crash chilling even in hot ambient temperatures in your garage or brewery.

The reservoir is completely enclosed including the removable lid, which aids in cooling performance due to less heat loss.


Refrigerant: r600a isobutane.
Cooling Power: 780W (1HP)
Tank: 30L Water Capacity
Max Head (per pump): 5 meter
Max Flow (per pump): 600L/Hr
Output Barb Size: 10mm OD 8mm ID
Dimensions: 410mm x 410mm x 660mm
Castor wheels included

Reservoir Digital Temp Controller

The temperature of the reservoir is set using the in-built STC-1000 controller. If you would like to download the PDF instruction sheet for this controller please click the link below:

Integrated Pumps
This unit comes with 4 integrated pumps and temperature controllers. This will allow you to cool up to four fermenters at the same time at different set temperatures. Set the temp on the main reservoir to -4C then (after you have added 20% glycol) then on the other side of the G40 set the other four temperatures to your ideal fermentation temperatures.  No additional wiring is necessary to cool a vessel.  Pumps included and already wired up ready to use.

Cool Your Bright Tank Fermenter/Kegmenter/FermZilla
Let’s face it.  Australia is a hot country and in many instances, heating is not necessary but cooling is essential.  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 yeast activity to heat the fermentation tank.  The G40 can be used to cool a range of different fermentation vessels when used with products such as the Temp Twister.

The KegLand G40 IceMaster glycol chiller can also be set up to provide dual cooling/heating control. The temperature controllers include heating terminals allowing the wiring of a heating device into the temperature controller. This allows the required temperature of the vessel to be set on the digital controller which will then automatically turn on or off the pump or heating device as required to maintain the optimum temperature.
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 3-6times 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.

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 G40 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 all these chiller options:
a) BrewZilla 65L Immersion Chiller
b) Coolossus Stainless Counter Flow Chiller
c) BrewZilla 35L Chiller
d) 20 Plate Chiller

Installation Requirements
This unit requires a 100mm Clearance around all air vents.
Regular maintenance of dust around the radiator is required to ensure optimum efficiency.
Ideally used with KeGLand Glycol/Water ratio of 20% to achieve -8°C freezing point
