Ampco Rolec DH

The ROLEC DH was developed by the Ampco Applied Products division with craft brewer needs in mind. This innovative product line offering was specifically designed to help the craft beer market meet its remarkable growth potential.

The ROLEC DH45, ROLEC DH90 and ROLEC DH250 models offer small to large scale breweries a safe and efficient way to dry hop and creatively induce flavors into beer. Rolec eliminates breweries safety concerns of dry hopping on a ladder at the top of a two-story fermenting tank. These fully portable DH systems powered by Ampco’s in-line SBI shear blending pump are used at ground level.

The SBI pump recirculates the fermenter while inducing dry hops and other induced media directly into the stream of beer; all from an oxygen free environment.

The DH90 and DH250 are built with a pressurized carbon dioxide chamber to mitigate oxygen intrusion. The DH45 is a smaller scale version offering a non-pressurized vessel utilizing a “blanket” of CO₂ to protect the product from oxygen intrusion. The DH45 is capable of induction on fermenters with a maximum height of 20 feet and can be used additionally as transfer and CIP pumps.
