Product Description: This counterflow wort chiller from Brew-Works, llc can quickly and efficiently chill your wort down to yeast pitching temperatures. Design: When we set out to design this chiller we want to build a chiller that was free of any plastics or rubber that can degrade over time when exposed to UV light and high temperatures. The result is this chiller utilizes an all copper design as copper also has excellent thermal conductivity properties making this chiller extremely efficient. The inner tube is also wrapped with a copper helical coil which ensures it remains centered in the outer tube so it is fully surrounded by cold water, and it also creates turbulence in the chilling water. So this feature enhances the efficiency of the chiller, and is preferred over convoluted tubing. As convoluted tubing creates small nooks and crannies were solids can get lodged and result in bacteria growth. What’s included: The box contains one counterflow chiller, one ½” stainless steel tee, close nipple, street elbow, a ½” stainless steel ball valve, and a stainless steel thermometer with a 3” face. The chiller also comes with the male and female garden hose connectors for the cold water connections. Materials: This counterflow wort chiller is made from 100% American made copper tubing, as we use tubing manufactured by either Mueller or Cerro. So unlike other brands that are simply reselling chillers that are made overseas this chiller is made with materials that are held to high quality standards. As all material meets both NSF and ANSI standards. The same standards for materials used to plumb your house. All fittings are soldered using lead free solder and flux. So with this chiller from Brew-Works you know both your wort and chilling water will be free from contaminants and safe to consume. Size: Approximately 7” D x 6” T. The length of the chiller is 12’6” (uncoiled).
