John Guest, pioneers of the push-fit connection technology, have done it again with a ground-breaking tube-in-tube beer dispense system, Polarclean®. The system is designed to overcome detrimental effects on beer quality caused by less efficient traditional contact cooling systems.
Most pub and restaurant owners will be aware of how difficult it can be to achieve consistently cold draught beer temperature in-glass without fobbing. Also keeping beer conditioned throughout the system is particularly important to maintain beer quality and freshness. This plays a critical role when complying with brand’s serving guidelines and meeting customer expectations.
Contact cooling arrangements found in most venues, conventionally use a python to convey beer from cellar to bar. Beer-lines in the python are wrapped around coolant tubes with resultant air gaps, tube wall thicknesses, and minimal surface contact with the coolant tube resulting in inefficient heat transfer.
The beer-line transferring beer from keg to cooler is neither contact cooled nor insulated, hence the cooler needs to flash cool the incoming warm beer, in its stainless steel coils. The extra cold beer then travels to the font in a contact cooling python, picking up heat on its way. The python’s length and the dwell time have a significant effect on the in-glass temperature.
Polarclean offers the most effective solution to these problems with its tube-in-tube technology. The beer is chilled in the tube-in-tube python the moment it leaves the keg, ensuring it is kept consistently cold throughout its journey to the glass.
Gary Hall, Polarclean Ambassador at John Guest, said:
Contact cooling is an inefficient method of heat transfer, when minimal surface contact exists between the round tubes. Beer-lines are challenged to deliver quality beer in glass. To overcome this issue the industry has deployed secondary coolers or heat exchangers under the bar to achieve desired temperatures in-glass. However, this localised temperature ‘bombing’ does not promote best of beer condition throughout the draught dispense system. Which is why discerning customers will often ask if a tap has been poured today?
Polarclean’s tube-in-tube technology, which fully envelopes each beer-line with recirculating coolant from keg to the tap, provides much quicker heat transfer. The system also offers greater installation flexibility enabling keg, cooler and font to be located remotely from each other.
The Polarclean system utilises the coolant from the cooler’s waterbath to recirculate around the entire system. This promotes end-to-end temperature consistency and reduces flash-cooling temperature variation. One of the crucial benefits of maintaining consistently low temperature is brand quality. With the absence of temperature variation comes less vulnerability to microbial activity from system ‘hot-spots’, reducing the chances of fobbing and off-flavours. This also reduces the need for frequent line cleaning.
For business owners, Polarclean is an ideal solution for maximising revenue per keg, with less beer in drip trays, less beer rejections, less ullage due to extended cleaning frequency and most importantly satisfied customers.
Polarclean also provides an opportunity to hotels, restaurants and other venues with space limitations and no cellar, to serve draught beer instead of packaged beer.
With many international brands already using Polarclean tube-in-tube technology, it’s about time you give it a shot.
