The enduring relevance of Billi’s Quadra system

Quadra: A Game-Changer in Under-Bench Water Technology

• Heat energy reclaim system that recycles energy to preheat boiling water
• Water-cooled technology that removes the need for ventilation or fans
• Compact under-bench design that saves space and reduces noise

“The end user has always been at the heart of our design philosophy,” says David Craggs, Head of Research & Development at Billi.

These innovations made Quadra quieter, more efficient, and easier to install, offering new design freedom for architects and engineers.

Evolving the Quadra Range

Today, the Quadra family includes:

• Quadra – Instant boiling and chilled filtered water
• Quadra Plus – Adds a sink mixer with separate hot and cold supply
• Quadra Twin Plus – Two mixer taps and filtered boiling/chilled water

Dispenser options include XT Touch, XR Remote, and XL Levered, with finishes ranging from matte white to urban brass. Accessibility options such as Braille pads are also available.

Quadra systems support different capacities, chilled water temperature ranges (6°C to 15°C), and varying current draws to suit any setting. Billi also provides refillable service plans for long-term support.

Powered by Natural Refrigerant R290

Quadra’s energy efficiency is driven by natural refrigerant R290, which offers:

• Zero ozone depletion potential (ODP)
• Global warming potential below 5 (GWP)
• Fast cooling and reduced energy use

These benefits are enhanced with polypropylene insulation, standby modes, and timer controls that help lower utility costs while reducing environmental impact.

Health, Safety and Water Quality

Quadra systems are engineered for optimal water quality and health with:

• Dual-stage filtration for sediment and chemical removal
• Bacteria-resistant filters for enhanced hygiene
• No VOC or BPA materials

Key safety features include smart lock technology and Splash Free™ spouts, ensuring intuitive, user-safe hydration experiences.

Certifications for Sustainable Building Projects

Billi Quadra products meet the highest environmental and performance standards:

• Global GreenTag Gold Level Certification
• WELL – IWBI member
• WaterMark Certified
• Product-Specific Environmental Product Declarations (EPDs)

With an RPV of 16, Quadra qualifies for Exceptional Performance in the Green Star Buildings rating tool, helping designers achieve sustainability goals more easily.

Product Development and Innovation

Billi continues to refine the Quadra range with new enhancements such as:

• OmniOne and Home BCS with integrated CO? canisters
• Improved touchscreen interfaces for customisation and safety
• Upcoming XT2 Touch dispenser with motion-sensor technology

 

“We’re even improving how users fill their cups to reduce strain and improve safety,” says Craggs.

As the design approaches energy efficiency limits, Billi is preparing for a new era of breakthroughs in compact, high-performance systems.

Global Leadership and Compliance

As Billi expands internationally under parent company Strix, it faces new sustainability benchmarks and regulatory standards worldwide.

“It’s about understanding our global impact and designing with purpose,” says Royce Tan, Brand Marketing Coordinator.

With a ranking in the top 35% of Global GreenTag and compliance rated “Ahead of the Market”, Billi is poised to lead globally in sustainable water technology.
