Billi Quadra System

The Billi Quadra has the smallest under counter unit footprint of its kind. With space at a premium in city offices, the Quadra is focused on space savings, and offers a significant benefit compared with others on the market. This allows the best use of precious storage space. Leading the Billi commercial range, the Quadra boiling and chilled range offers unrivalled performance and efficiency.

The world's first water-cooled under counter system still leads the market on technology. Allowing highly compact dimensions, requiring no ventilation and yet still offering market leading instant dispense rates. The Quadra recovers and re-uses waste heat energy using technology to make it the most efficient system available today.




Billi Filter Cartridges

The Billi Quadra and Quadra Plus feature the Billi dual stage swing-change filtration system. Quadra models 420 and upwards incorporate two filter cartridges, a sediment removal pre-filter and high quality carbon block chemical removal post-filter. The Quadra Compact is fitted with single dual stage filter incorporating sediment and chemical removal elements. All Quadra filters are manufactured using bacteria and biofilm resistant materials for improved water quality. Standard filters will remove sediment particles greater than 5 microns, as well as chemicals, tastes and odours present in the water supply. Premium filters provide better tasting water due to the high quality, carbon chemical removal filter. Rated to remove sediment particles greater than 1 micron, these filters have excellent chemical absorption, removing or reducing chlorine, volatile organic compounds (VOCs), chemicals, tastes and odours. Special purpose filters designed for cyst reduction and heavy metal removal are available. Contact Billi Pty Ltd.
Use only genuine filters as designed for this system. All drinking water filtration systems should be flushed after a period of non-use. Your Billi Quadra has an automatic flushing cycle which can be activated. After a period of non-use of more than two days, e.g. off Saturday and Sunday, the cold water will flow for 90 seconds when the time switch first turns the unit on. Alternatively, before use, lift the cold lever and run until water flow stops, then release the lever.

Filter Change Due Monitor

The Quadra filter change due monitor operates by counting the number of cups dispensed and the number of days elapsed until a pre-set level is reached. Once reached, the dispenser icons will briefly change to orange once every five seconds. The Quadra will continue to operate while the filter indicator is flashing. Water filters installed in areas with higher levels of turbidity (cloudiness/sediment) will experience a reduced service life. The flow from the cold water outlet will decrease as the filters become blocked. It may be necessary to change filters before the change filter indicator flashes. The filter monitor can be reprogrammed to an appropriate service interval if required. Contact Billi Pty Ltd. Standard 5 micron-rated filters generally have a longer service life than Premium sub micron-rated filters. If particularly dirty water is noticed coming through the water supply, e.g. from other tap ware, as sometimes occurs following repairs to local water mains, immediately turn your Billi Quadra off using the ON/OFF button. This will help prevent premature blocking of the filter cartridges.

Replacement of Billi Filter Cartridge

Periodic replacement of your Billi Quadra’s Water Filter Cartridges is necessary to maintain the sparkling cleanliness and purity of your drinking water. A replacement filter change service is available. To arrange, contact The Water Shop on 02 9458 1111. If you wish to install the replacement filter cartridges yourself, filters can be purchased online through The Watershop, which will provide you with genuine Billi replacement filter cartridge sets.
Once new filter(s) have been installed and the filter flush cycle is complete, check for any water leakage around the filter system. Take particular care to ensure the area around the water leakage sensor, located on the lower left hand side of the bulkhead behind the filters, is dry. If you have any questions, or concerns during the filter change process simply contact The Water Shop’s experienced technical assistance team on 02 9458 1111.

Features & Benefits

Energy efficiency

Billi’s unique energy reclaim system recovers waste heat energy generated by chilling water and reuses the energy to preheat the boiling water, thereby making a substantial energy saving. By careful consideration of the composition and construction of each component in our own Australian plant, the Billi achieves the lowest carbon footprint. In addition all Quadra units include a 7 day, 24 hour time switch to conserve power, or alternatively can be put into Standby mode which conserves energy by powering down after a prescribed period of non use.

Time efficiency

With its highly efficient heat harvesting technology the Billi Quadra dispenses more cups instantly than any tap of its kind on the market. This allows for peak periods of high demand in the teapoint or canteen environment. Billi regards instant dispense as the most important measure of a boiling and chilled systems capacity.


The Billi Quadra is unique as it does not require cupboard ventilation or ventilation grilles. It has no cooling fan, and instead uses a water cooling system which greatly enhances efficiency, saves space and cuts costs.


All our Boiling and Chilled dispensers come with an integrated safety switch. The red lock icon demonstrates when the safety switch is activated, simply press the switch to release the lock and allow full use of boiling water. The system will revert to safety mode after 8 seconds of non use.

Splash free delivery

Electronic control of boiling water delivery ensures user safety. The flow is momentarily slowed as the water exits the dispenser, eliminating splashing as the water enters the cup.

Designer taps

Following collaboration with architects, designers, engineers and end users, Billi has created an exceptional range of dispensers to suit our Boiling and Chilled systems. Comprising three different styles of tap in four finishes and a corresponding drainage font, this range ticks all the boxes with clean sophisticated style, advanced safety technology, ease of installation and energy efficiency.

Billi premium filters ensure that health threatening pollutants and impurities such as sediment, chemicals, heavy metals and pesticides are removed leaving you with refreshingly clean drinking water, every time.
