Diy Glycol Chiller

A DIY glycol chiller is a homemade device that uses a refrigerant to cool glycol, a liquid that has a lower freezing point than water. This makes it ideal for use in applications where temperatures need to be kept below freezing, such as fermentation chambers.

To build a DIY glycol chiller, you will need the following materials:

• A window-mounted air conditioner
• A large cooler
• A submersible pump
• A temperature controller
• Food-grade propylene glycol
• Distilled water
• Tubing
• Connectors
• Plywood
• Caster wheels
• Tools

Once you have gathered your materials, follow these steps to assemble your glycol chiller:

1. Cut a hole in the lid of the cooler that is large enough to fit the evaporator coils of the air conditioner.
2. Mount the air conditioner on the lid of the cooler, using the plywood to create a platform if necessary.
3. Connect the submersible pump to the temperature controller and then to the evaporator coils.
4. Connect the temperature controller to the power outlet.
5. Fill the cooler with a mixture of food-grade propylene glycol and distilled water. The ratio of glycol to water will vary depending on the temperature you need to achieve, but a good starting point is a 1:2 ratio.
6. Connect the tubing to the submersible pump and to the fermentation chambers that you want to cool.
7. Insulate the tubing with pipe insulation to prevent heat loss.
8. Attach caster wheels to the bottom of the cooler so that you can easily move it around.

Your DIY glycol chiller is now complete! To use it, simply set the temperature controller to the desired temperature and turn on the air conditioner. The submersible pump will circulate the chilled glycol through the fermentation chambers, keeping them at the desired temperature.

Here is a simplified English description of a DIY glycol chiller, without paragraph numbers or titles:

DIY Glycol Chiller

• A device that cools glycol using a refrigerant.
• Glycol has a lower freezing point than water, making it ideal for use in applications where temperatures need to be kept below freezing.
• DIY glycol chillers are often used in homebrewing to control the temperature of fermentation chambers.

Materials:

• Window-mounted air conditioner
• Large cooler
• Submersible pump
• Temperature controller
• Food-grade propylene glycol
• Distilled water
• Tubing
• Connectors
• Plywood
• Caster wheels
• Tools

Instructions:

1. Cut a hole in the lid of the cooler for the air conditioner evaporator coils.
2. Mount the air conditioner on the lid of the cooler.
3. Connect the submersible pump to the temperature controller and the evaporator coils.
4. Connect the temperature controller to the power outlet.
5. Fill the cooler with a mixture of food-grade propylene glycol and distilled water.
6. Connect the tubing to the submersible pump and the fermentation chambers.
7. Insulate the tubing with pipe insulation.
8. Attach caster wheels to the bottom of the cooler.

Usage:
