Cooling with glycol

We supply cooling systems using Quantor glycol chillers. The system is based on a single pump and solenoid valves and it's prepared for our future fermentation control system.

The flowchart shows how the system is set up. Recommended components for each section is found below.

We're working hard on our complete fermentation control system which will be compatible with these parts.

#1 - Quantor Glycol Chillers

German manufacturer Quantor makes high quality chillers. We stock 3 models with the specifications shown in the table (Based on data from the manufacturer).

Take note that the capacity requirements is affected by ambient temperatures and how much exothermic heat is generated during fermentation. The data is based on average use.


#2 - Glycol chiller fittings

Quantor glycol chillers comes standard with G3/4" threaded connectors. You can use our standard G3/4" to 12mm hose adapter or go via Tri Clamp. You can also completely replace the G3/4" connectors from Quantor with our own adapter to avoid threads completely. Remember gaskets for G3/4" connectors

#3 - Tubing

Our EVA+PE and EVA tubes are perfect for glycol. We have them both insulated and non-insulated.
We recommend using our insulated 12x18mm tube for the main glycol line and our insulated 8.5x14mm tube for the tanks.

#4 - Joints and valves

To connect the tubes we use our stainless steel tee and tube valve The tube valve is installed at the end of the loop and it's used to control the counterpressure. The tube valve must never be fully closed. Use hose clamps on all connections.

#5 - Tank connections

We have many options for connecting the cooling tubes to the tanks. If the tanks are not required to move, we recommend using the TC34mm to 10mm elbow, but many also prefer our quick connectors.

#6 - Solenoid Valves

To control the cooling function on the fermenters we use one solenoid valve per tank.

We have developed our own solenoid valve specifically for glycol, air and water. Check out the solenoid valve and accessories for it below.

The solenoid valves are NC (normally closed) and require 24V DC to open the cooling circuit. You can use a control system or a simple 24V DC Power Supply (15W+) to power the valve coil.

The solenoids should have a hose barb or quick connector (normally via a 3/8" adapter etc) with an outer diameter of 9-10mm for 8.5mm tubing. Se #5 regarding connectors.
