K/GFL Series


One-door type makes carrying in/out easier and conserves space
This series has a narrow front width and can be delivered and installed anywhere having a width of a single door (approx. 800mm). There is no need to install a new delivery entrance.

Low NOx specifications
This series has achieved low NOx emissions of 60ppm or lower (converted at O2=0%, gas-fired). Environmentally friendly and low pollution combustion is realized. (GFL-160 to 800 models)

Multi-circuit supply unique to the Vacotin Heaters
In addition to hot water supply and heating, simultaneous supply by three or four circuits can also be realized in accordance with your purposes.

Mechatronics water heater
Leveraging mechanical engineering and electrical engineering, the heater has enabled direct control of the water temperature by using a microcomputer and achieved energy saving.

Focuses on safety
The inside of the vacuum heater is designed not to expand, explode, or get damaged in principle. The boiler always contains a certain amount of heat-carrying water, eliminating risk of heating without water.

Prevents corrosion and failures
The heater contains no air in the inside and is sealed to completely shut off the air outside, resulting in no corrosion.
Using SUS444 stainless steel for the flange type heat exchanger, the heater has largely improved durability and ealized a longlife with no corrosion.

Prediction function
The history of the prediction function is maintained, which has realized immediate responses based on accurate decision.
In addition, the heater takes instantaneous measures against power failure to ensure its safe operation.
