On-Wall Boiling Water
Description

Zenith On-Wall Boiling Water Solutions are wall-mounted, instant boiling water appliances manufactured in Australia and engineered for commercial environments such as workplaces, restaurants, canteens, and cafes. The range utilises twin-chamber boiling water steam-heat-boost technology, which recycles energy from steam to pre-heat incoming cold water.

Depending on the specific model, the units feature either highly accurate electronic temperature monitoring or standard thermostat control. Outer casings are finished in a neutral white case. The main boiling water tanks are wrapped in high-performance insulation to optimise efficiency and maintain thermal performance.

The range consists of three primary models to suit different project demands:

  • Zenith Hydroboil Plus: The premium option designed for modern workplace kitchens, integrated with 0.2-micron MicroPurity filtration, a programmable digital display, two energy-saving modes, and an integrated, flush-mounted, cool-to-touch tap.
  • Zenith Autoboil: An electronically controlled option equipped with 0.2-micron MicroPurity filtration, a digital display, and a classic external two-way tap.
  • Zenith Econoboil: An entry-level option utilising manual thermostat temperature control and a classic external two-way tap, designed for temporary or budget-focused installations such as site sheds.
Key Features
  • Steam-Heat-Boost Technology: Utilises a twin-chamber design to recycle steam energy and pre-heat incoming cold water for enhanced efficiency.
  • PowerPulse Technology: Delivers precise micro-pulses of energy to the heating element to maintain digital temperature control within 0.2°C of the set point (Hydroboil Plus models).
  • Self-Calibrating Functionality: Automatically determines the exact boiling point relative to altitude, ensuring optimum performance from sea level to high elevations without over-boiling.
  • Advanced MicroPurity Filtration: Combines activated carbon and 0.2-micron sediment removal into a single hygienic cartridge certified to reduce bacteria, sediment, and odours to NSF 42 and NSF 53 standards (Hydroboil Plus and Autoboil models).
  • Energy-Saving Sleep Modes: Programmable ON/OFF timers and 'sleep when dark' modes reduce energy consumption during low-demand periods (Hydroboil Plus and Autoboil models).
  • Touch-Free Adaptability: Compatible with a retrofittable, grade 304 stainless steel touch-free tap adaptor allowing users to dispense boiling water sanitarily by pushing a cup against the handle.
Scope of Use
  • Recommended for commercial applications such as offices, workplaces, restaurants, canteens, cafes, and site sheds.
  • Available in nominal storage capacities ranging from 3.0 to 40.0 litres, delivering between 18 and 240 cups at one time, with recovery rates up to 350 cups per hour depending on configuration.
  • Wall-mounted over sink or drain

     

Limitations on Use
