Characteristics of new product

  • By maximizing efficiency (based on low heating value), a high efficiency of 102.5% has been certified by the Korea Energy Management Corporation.

  • By greatly reducing O2 and NOx in emission gas, heat loss from emission gas was minimized and the environment was significantly improved.

  • By adopting the combustion control system with the highest safety certification grade in Europe of SIL3 from the TUV in Germany, the best safety operation is assured.

  • The cutting edge smart function was integrated enabling monitoring of the operation status of the installed boiler from all locations using a PC/smart phone on the internet via internet web server.

What is ECO-GREEN operation?
A cutting edge operating method enabling low NOx of under 40 ppm at a boiler load changing sector (20-100%) and high efficiency of over 98% with an electronic two-damper air fuel ratio control system by adopting a Riello low NOx burner, LMV5 of Siemens and Climatix

LMV5… O2 Trimming Control
What is a system?
A system that measures the amount of O2 in the emission gas generated from an operating boiler, and saves energy cost by optimizing combustion efficiency by trimming the number of rotations in the inverter fan and combustion air damper.
  • In 10-60% of load, the air and gas damper opens at a certain ratio to operate with a set O2 value, however, when the load increases to 70%, the air damper deviates from the ratio range generating heat loss due to excessive air. During this, the O2 value is reduced to the range of minimizing heat loss due to O2 trimming control. Also, the trimming of air moves along the set curve, and prevents the hunting of an O2 value through predicting the control function.
  • The graph above shows trimming the O2 value by moving the air from 52 to 35 and the inverter (VSD) from 85 to 75 while maintaining the location of the gas damper based on a 70% load at 40.
