Cooling System Guide

Below you will find a guide for how to set up a cooling system for your fermentation tanks.

We offer both a single pump system for larger tank setups and a "one pump per tank" system for up to 4 smaller tanks. Our submersible pumps connects directly to our Fluid Control System (FCS). See FCS guide for more information.

The system diagram below shows how the system will be configured for most users using a single pump.

#1 - Chillers / Glycol

We will soon announce a new partnership for Brewtools customized chiller for both submersible pumps and single pump.

#2 - Chiller connection

Depending on the chiller you have, connection method will vary. See our valves and fittings products.

Brewtools chillers with a single pump uses pushfit directly with the main cooling lines, so there is no need for added connectors.

#3 - Main cooling lines

Our EVA+PE-python, 12x18mm is intended for the main cooling line. The thick insulation reduces condensation. The tube valve is installed at the end of the loop, and it's used to control counterpressure. The tube valve must never be fully closed. Use hose clamps on all connections.

We recommend ordering:

- EVA+PE-python, 12x18mm (length depending on distances)
- Tube Tee 12mm/10mm (2 pcs per fermenter)
- Tube valve, 12mm (1 pcs)
- Hose Clamp, 12-22mm (4 pcs per fermenter + 2 pcs for tube valve)

#4 - Tank cooling lines

Our EVA python, 8.5x14mm is intended from the tube tee to the fermenter. The thick insulation reduces condensation. Use hose clamps on all connections.

We recommend ordering:

- EVA python, 8.5x14mm (length depending on distances and number of tanks)
- Hose Clamp, 12-22mm (4 pcs per fermenter)

#5 - Tank connections

We recommend using 3/8" quick connectors for cooling lines.

We recommend ordering:

- TC34mm to 3/8" F-NPT (2 pcs per fermenter)
- Quick connector, Female to 3/8" NPT (2 pcs per fermenter)
- Quick connector, M elbow to 10mm barb (2 pcs per fermenter)
- Hose Clamp, 12-22mm (4 pcs per fermenter)
- Solenoid valve, TC34mm, NC, DC24V (1 pcs per fermenter)
- Tri Clamp (2 pcs per tank. 1 extra if using Solenoid on tank)
- TC gaskets (1 pcs per Tri Clamp)

See our FCS guide for solenoid valve cables.

If you want to use another control system, we have a 230V power supply with a DIN43650 type A connector for our solenoid valve below.

#6 - Thermowell

Select the thermowell that fits your need. Choose between TC34 model for mounting in front of our fermenters or TC1.5” for right hand side mounting.

Also, choose the preferred length. As a rule, we recommend 90mm for F40 and F80, and 160mm for F100, F150 and F300.

See our FCS guide for temperature sensors.

Thermowells are mainly for other control systems.
