Steam Condenser for Grainfather G40 & G70 I Steam Condenser

Steam condenser for Grainfather G40 and G70 – brew indoors without steam in the room

An effective steam condenser for Grainfather G40 and G70, with custom Tri-Clamp components for easy installation and fewer parts to take apart, so cleaning is quicker. It is practical when you brew indoors and do not have a powerful enough extraction system to remove the steam.

A steam condenser is a relatively inexpensive and simple tool that eliminates the problem of a brewing room full of steam, and a good alternative to an extraction system with a fan and pipes hanging from the ceiling. Condensing steam is also common practice in most breweries.

How it works

Cold water is sprayed through a full cone nozzle at a 30 degree angle directly onto the steam, so that the steam condenses into water. The water flows out of the bottom of the condenser into a drain or a bucket. The unit uses approximately 0.6 litres of water per minute at 4 bar water pressure.

When the steam condenses inside the unit, it contracts and creates a vacuum inside the brewing machine, which draws the steam into the condenser. This ensures that all steam and DMS are carried away.

The lid comes with a clamp. You do not need to use the clamp while brewing, because the lid fits tightly. Without the clamp it is also easy to lift the lid when you add hops during the boil.

How to use the steam condenser

1. We recommend fitting the condenser once the foam from the hot break has settled. Feel free to use anti-foam.
2. Enter «Power Control Mode» and reduce the boil power. We recommend setting the power to 60 % and adjusting up or down as needed (tested with Grainfather G70). 60 % power gives a nice rolling boil while saving energy.
3. Fit the condenser, with cold water connected at the top and a 20 mm silicone hose at the bottom leading the water to a drain or bucket.
4. The water must be able to flow freely downwards so that no resistance builds up inside the condenser. The open end of the hose must not be submerged in water.
5. To add hops and other ingredients during the boil, simply lift the lid.

Boiling at reduced power also reduces evaporation accordingly. Compensate by using less sparge water. For example, with a 50 litre boil volume at 60 % power you get approx. 3 litres of evaporation instead of approx. 5 litres at approx. 10 % evaporation per hour.

Water connection

The steam condenser has a 1/2" NPT connection at the top, so you are free to choose how to connect the water. You can fit a hose barb or a Gardena quick connector, for example.

Frequently asked questions about the Grainfather steam condenser

How much water does the steam condenser use?

Approximately 0.6 litres per minute at 4 bar water pressure.

Do I need to adjust my recipe when using the condenser?

Yes, if you boil at reduced power. Evaporation will be lower, so you should use less sparge water. With a 50 litre boil volume at 60 % power you get approx. 3 litres of evaporation instead of approx. 5 litres.

Can I add hops while the condenser is fitted?

Yes. The lid fits tightly without the clamp, so you simply lift it off and add hops or other ingredients.

Which Grainfather models does it fit?

The steam condenser is made for Grainfather G40 and G70.
