Technical Details

Overview

The Bräu Supply stainless steel counterflow chiller is designed for fast, efficient, and sanitary wort cooling during knockout. Built with a 30’ coil-in-coil configuration, it delivers performance comparable to a plate chiller while offering easier cleaning and less risk of clogging.

The wort side features 1.5″ tri-clamp fittings for secure, sanitary integration with your brew system. The water sideincludes ½″ 304 stainless steel quick disconnect (QD) fittings with silicone seals for fast, tool-free hose connection. Each unit includes a complete water connection kit with reinforced hoses, a ¾″ garden hose adapter, and a sink faucet adapter.

⚙️ Installation

  1. Connect the wort inlet and outlet to your brew kettle and fermenter using 1.5″ tri-clamp fittings.
  2. Attach the included braided hoses to the QD water ports.
  3. Connect the hoses to your cold water source using either the ¾″ garden hose adapter or the sink adapter.
  4. Orient the chiller so that wort and water flow in opposite directions for optimal heat exchange.

💡Flow Direction:• Cold water in → bottom QD port• Warm water out → top QD port• Hot wort in → top tri-clamp port• Chilled wort out → bottom tri-clamp port


⚠️ A wort pump is recommended for consistent flow and optimal chilling, though gravity feed is possible with proper elevation and control.

❄️ Operation

  1. Begin cold water flow first to pre-fill the outer coil and prevent thermal shock.
  2. Once water is flowing, pump or gravity-feed hot wort through the chiller.
  3. Adjust water flow as needed to control wort outlet temperature.
  4. Transfer chilled wort directly to your fermenter.

🧼 Sanitizing & Cleaning


Hot Wort Sanitization

This chiller can be effectively sanitized by running hot wort through it during the final 5–10 minutes of the boil. This method eliminates the need for chemical sanitizers and ensures the wort path is sanitized immediately before knockout.


✅ This is the preferred method for fast, chemical-free sanitization.


Post-Use Cleaning

  • Flush both wort and water circuits with hot water immediately after use.
  • For deeper cleaning, circulate brewery-safe cleaner (e.g., PBW) through the wort side.
  • Rinse thoroughly and allow to air dry.
  • Disconnect hoses and store dry to protect seals.
  • Inspect silicone QD seals and tri-clamp gaskets regularly.

Coil in Coil Counterflow Wort Chiller

I received this item in a very timely manner. However the box was in poor shape thanks to the postal service. The reason the connections for this unit may be missing because of the damaged box. I thought I ordered everything but it may have been my oversight.
I do need these parts. If I overlooked them, I will be happy to purchase them. If there is another reason for them to be missing, then can work out the details
My husband is really anxious to try out his new “toy” so I hope we can get this settled quickly.
