The Ultimate
Brewing Solution
Efficiency, flavour and cleanliness: these are the key words when it comes to the ultimate brewing solution. ULTROM redefines brewing and revolutionises it. By combining ultrasound with a horizontal mixing drum, the mash is stirred to perfection. The cavitation created by the ultrasound accelerates hydrolysis, increases the yield and improves the flavour of the beer. All in one compact, clean unit.

Proof
Ultrasonic cavitation breaks down the starch in the malt without destroying the grain. The enzymes gain more surface to work on and demonstrably convert the starch into sugar faster and more completely. The degassing caused by the ultrasound improves the yield. Homogeneous stirring of the mash distributes the cavitation evenly throughout the medium. ULTROM's low stirring resistance makes it possible to stir the mash again at any time, whether because of lautering problems or technical failures such as a power cut. In the lautering process in particular, ULTROM is the only brewing system that can rewash the mash at any time, without exposing the wort to too much oxygen. This increases efficiency.
Efficiency
With over 95%* brewhouse efficiency, ULTROM revolutionises brewing. The drum is fully insulated and heats the medium from all sides: fast heating, an even, stable temperature and high energy efficiency. As mashing and lautering take place in ULTROM, no solids need to be pumped – only the wort goes to the kettle. While it boils, the next brew can already start in ULTROM. This saves time and energy. Mashing in is easier too: no lumps form in ULTROM, so the malt can be added faster and hassle-free.
* US calculation, based on the maximum obtainable extract. Using the common German calculation (based on the grist, of which approx. 80% is hydrolysable), this corresponds to over 76%.
Compactness
This ultrasound drum requires no headspace and is thus 35% more compact than conventional two- or three-vessel brewhouses. Furthermore, as the vessel is closed, no ventilation system is required. ULTROM is closed, double-walled and can be filled to the top, which makes it more economical than other brewing systems.
Flavour
Ultrasound degasses brewing water and mash, lowering the dissolved oxygen. Together with the closed drum, filled to the brim, this means less oxidation during mashing. Oxygen-dependent enzymes are slowed down: lipoxygenase, which leads to staling flavours, and ascorbate oxidase (AAO), which breaks down ascorbic acid. This better preserves the malt’s natural antioxidants. The result: a fresher taste, better flavour stability and aroma that is preserved in the mash – particularly valuable for alcohol-free beers. Thanks to the covered, round shape of ULTROM and its comparatively small openings at the top, any CO₂ that is added cannot escape easily.
Quality
This patented brewhouse stands for Swiss quality and reliability. The finest ultrasound technology from Weber Ultrasonics AG (Karlsbad near Karlsruhe, Germany) is known as a quality product and appreciated by customers all around the world. Thanks to a special welding process, the system is built to last. ULTROM is available as an addition to existing breweries or as a complete brewhouse.
Clean
When the ultrasound is switched on, cavitation cleans ULTROM by itself. No shovelling of spent grains is needed: they slide out easily at the end of the drum into a container.
