Craft breweries in Australia have been experiencing fantastic growth in popularity, offering customers more than just alcohol. They offer sophisticated tastes and aromas, great variety of types of beer, and cult of artisan beer that goes well with gourmet meals or artistic events.

There are many factors contributing to the triumph of craft beer in Australian market, from quality compounds and knowledge of brewers to witty marketing efforts promoting artisan beers. However, long lasting success can only be achieved if the brewing equipment is selected wisely.

The boiling of wort is essential in beer making, and the brewer needs to maintain the right "rolling boil" brewing temperature to achieve the desired evaporation.

Basically, the control system of a brewery vessel should allow modulations between automatic and manual control to attain the specifics of each blend. Brew coppers and hot liquor tanks need to be efficient to allow the brewers achieving their margins and save on energy costs.

When choosing the brewery vessel heating system, the beer makers use steam or high pressure hot water generated by boilers, electric heaters or gas heaters with immersion tube heat exchanger.

While bigger plants can invest in boilers, mini breweries choose between electric or gas fired heating systems.

For vessel sizes 600 to 10000 litres, with require heat input is 15 kW to 700 kW, the most efficient solution is immersion tube heat exchanger, fired by the gas burner.  Lanemark tank heating installations, offered in Australia by Hurll Nu-Way, provide helical coil immersion tubes diameters between 3.8 and 15 cm to fit into both cylindrical and rectangular brewing vessels.

Helical coil design warrants minimum intrusion into the brewing volume, which contributes to overall operating efficiency. 

The coil immersion tube heat exchanger is connected to the externally mounted gas burner, which can be run on gas or LPG. Lanemark system provides over 80 per cent efficiency allowing cutting on heating costs. Such burner system raises the temperature of the vessel from 60°C to 100°C in just one hour.

Modulating control system allows the brewer maintaining the optimum brewing temperature and manufacturing the beer of desired qualities.

Microbreweries in England have been benefiting from this technology for over 25 years, and Hurll Nu-Way is happy to offer Lanemark tank heating systems to Australian artisan brewers.

Another sensitive issue of beer making is gentle transfer of beer, especially unfiltered, protecting yeast, proteins and malts from shearing, and a steady feed of beer into centrifuge, minimizing pulsations.

Low pulsations are crucial to ensure efficient operation of the centrifuge. The secret of American craft brewers is eccentric disc pump from Mouvex (available in Australia via Hurll Nu-Way). 

This pump is low shear, low pulsation pump, also offering strong suction, which allows extracting all product from the tanks and increases beer yield. Seal-less design of Mouvex pump warrants beer from oxidizing as no air enters the system. Absence of seals also means considerably lower maintenance and downtime.

Same pump can be used for cleaning in place the tanks from sediments.

One of the final stages of beer manufacturing is labelling, which requires dry bottles, and ideally it should be done with low energy consumption. The solution here is blower powered air knife system, also available via Hurll Nu-Way. Saving up to 85 per cent of running costs compared to compressed air knives, Secomak air knives are easy to install and require minimum maintenance, further contributing to success of the craft brewery.
