Product Introduction

The fully premixed low-nitrogen condensing boiler produced by Henan Leway Thermal Equipment Manufacturing Co., Ltd. is a high-end natural gas boiler product. Its safety, stability, excellent performance and quality have been recognized by the industry. With professional system integration technical support capabilities, it can provide professional and customized system design for customers in different business formats, solving integrated solutions for customers from heat source to terminal, from heating to hot water supply, and from automatic control to the entire network, with a comprehensive energy saving rate of up to 30%.
It has wide adaptability and can be widely used in winter heating and domestic hot water systems of residential buildings, office buildings, schools, hospitals, hotels, shopping malls and various industrial buildings. Combined with soft water, make-up water, heat exchange, electric control systems, etc., it provides heat source in the form of atmospheric pressure boiler plus secondary heat exchange.

Feature Description

1. Adopt original imported accessories with superior performance. 
2. Fully premixed condensing technology with more reasonable air-fuel ratio.
3. Adopt Bekaert silicon-magnesium aluminum alloy heat exchanger with high heat transfer efficiency and strong corrosion resistance.
4. Power 60KW-2800kW. Heating area 600-46600㎡. Thermal efficiency 108%.
5. Energy-saving and high-efficiency, saving more than about 35% energy compared with ordinary boilers;
6. Environmental protection, NOx emission (comprehensive average value) at 30mg/Nm³;
7. Microcomputer intelligent control, convenient operation;

Product Advantages:

Energy-saving and high-efficiency: efficiency increased by more than 35% compared with ordinary boilers, operating costs significantly reduced, high efficiency and energy saving, thermal efficiency up to 108%. Low-nitrogen combustion: low NOx emission, nitrogen emission below 30mg/Nm³, meeting the national boiler air pollutant emission standards. Small footprint: for a heating scale of 100,000 square meters, the boiler room occupies only 60 square meters. Small footprint, easy installation. Wheeled support for convenient shifting, PVC chimney reduces costs, easy installation, long service life
Longer service life: core components such as heat exchangers are original European brands with quality assurance, ensuring long-term stable operation of the equipment, with a service life of more than 30 years. After-sales service: We realize remote after-sales management of boilers, with full coverage of after-sales service without blind spots
Low maintenance cost: simple structure, high-quality accessories, strong versatility, few wearing parts. The use of high-power variable frequency fans greatly reduces later maintenance costs. Short installation cycle: Our condensing heating units can shorten the boiler room installation time to less than one week. Worry-free use: strong pre-sales technical support and perfect product after-sales service
