Whether you are a home brewer with your own brewing system, or the Brew Master at a world class micro-brewery, ZChillers brings your wort to temperature fast and predictably. ZChillers are all copper, counter flow wort chillers that come standard in a compressed, helical shape. They utilize a “tube-in-tube” design, with a smooth copper outside tube (for the coolant) and a convoluted, spiral star inside tube (for the wort). They are small and attractive and while providing precision wort cooling capability, a perfect addition for any size brewing system, needs no ice. . Our original design created with small-batch homebrewers in mind. Compact, efficient, and recommended for batches of 7.5 gallons or less.
