EQi-2000/2500

Ultra-high efficiency and power saving

EQi-2000/2500

An industry leading boiler efficiency of 99% is achieved through low air ratio combustion.The blower fan speed is controlled by the inverter according to the boiler load to significantly reduce the blower power consumption at low load.

Boiler efficiency of 99%, Turndown ratio of 5:1  (4 position control)

Space-saving design

It is a slim and compact boiler with an installation width of 900 mm, which is one of the smallest in the industry.

Ultra-low emission combustion

The Jet Film CombustionĀ® technology achieves ultra-low emissions with NOx of 25 ppm and CO of 30 ppm at low air ratio.

Ultra-high efficiency

EQi-3000/EQiH-3000
Boiler efficiency of 99%, Turndown ratio of 5:1  (4 position control)

Low NOx emissions

The pre-mixing split-flame burner achieves NOx of 60ppm or less (converted to 0% O2)

EQi-6001/EQiH-6001

Industry #1 ultra-high efficiency

Rated load efficiency of 99%, Part-load efficiency of 101%  (at 40% load)
Partial load efficiency

PI control (for pressure)

PI (Proportional-Integral) control keeps the boiler pressure stable regardless of whether the load is static or fluctuating.

[Pressure fluctuation range]
At static load +-0.005MPa, At fluctuating load +-0.025MPa
Steam pressure during automatic opaeration, steam dryness (with respect to the steam load)
Steam pressure during automatic opaeration, steam drynessSteam pressure during automatic opaeration, steam dryness

Low environmental impact

Turndown ratio of 8:1  (position control), NOx of   55ppm or less  (for natural gas 13A), Low air ratio of 1.2

Blowdown control responsive to feedwater flow rate variations (Patent No. 5826539)

By increasing or decreasing the continuous blowdown flow rate as the feedwater flow rate changes, heat recovery of the blowdown water can be performed efficiently at any boiler load.
