Masterpiece made from 40 years of Kiturami craftsmanship

  • Kiturami's patented-technology, stainless heat exchanger, with its complex structure of platen heating elements - which are made of seamless brazing nickel - guarantees\ excellent durability.
  • Because hot water pipe made of high-end stainless material was applied to insulated hot water tank, sufficient amount of water is provided and its hot water heat exchanger is just secure from blockage due to foreign substances.
  • An air/gas ratio control valve is used to control gas volume according to air volume to achieve low noise and burn stably even when the flue is up to 10M long and bent up to 5 times.
  • Quicker, more sophisticated flame control is ensured, as the flame size [Turn Down Ratio (TDR)] can be adjusted up to 30%. Even if it's just small amount of heat water, you can use heat water stably without temperature change and set water temperature by 1°C.
  • Low power consumption is achieved by keeping the standby power under 3W.

Eco-friendly low-NOx boiler

  • We've achieved a Korean NOx Grade 1 by producing a small amount of NOx through the surface combustion of a specialized metal-fiber burner.

Boiler with utmost safety

  • A gas leak detector is provided to avoid explosion or poisoning due to gas leakage.
  • A seismic detector is provided to stop boiler operation when detecting a 4~5-magnitutde earthquake or vibration.

Internal Structure

  • 1) Kiturami's exclusive built-in gas leak detector

    The safest device to stop boiler operation and warn of gas leakage when gas is exploded or waste gas (burned gas) is leaked

  • 2) Seismic detector

    The safest device (applied cutting-edge gyroscope-type technology) to prevent gas explosion and fire and reduce any secondary damage when detecting 4~5-magnitutde earthquake or vibration and considering the status of Korea where is no longer safe from earthquake

  • 3) All stainless heat exchanger

    Seamless brazing type 3-Pass heat exchanger in compact size (STS304 Brazing)

  • 4) Premix metal-fiber low-NOx burner

    A special burner designed to minimize NOx emission through stable gas burning

  • 5) Open vented hot water expansion tank

  • 6) Controller

  • 7) Air/gas ratio control valve

  • 8) Circulating pump

  • 9) BLDC fan

Mobile Control System Through IoT

Operate your boiler easily with your smartphone in/out of your house anytime, anywhere

  • Don't try to remember if you turned on or off the boiler. You can check if your boiler works or not in your smartphone.
  • With your smartphone, you can control the functions and room temperature just as you like and set your rooms pleasant when you are out.
  • You can set the boiler operating schedule anytime in 24 hours a day.

A/S

  • If any trouble happens in your boiler, its system automatically notifies you to get relevant service immediately.
  • Kiturami Customer Center, associated with your boiler system, collects and monitors your troubleshooting history, boiler status, etc., to offer the best in follow-up boiler maintenance.

Though you already have old Kiturami boiler

  • you can control it wirelessly only if you have IoT remote control.

Smart learning

  • The system analyzes and learns user's habits of boiler using to provide ideal temperature schedule service through optimized pattern analysis.

IoT based international communication standards

  • The system can connect with various local/overseas products by adopting international standard IoT platform.
