Commercial Gas Hot Water Boiler C6

Maximum Heating Capacity per Unit: 1.4MW
Similar to the V6, the C6 model features a vertical design and utilizes gas fuel. Notably, it can deliver a heating capacity of up to 1.4MW, capable of heating areas up to 20,000 square meters (excluding hot water supply). It is well-suited for commercial environments such as shopping malls, service stations, train stations, hotels, and resorts.

Compact Design: The wing pipe heat exchange area is 13 times greater than that of seamless pipes, allowing for a significantly smaller boiler size while still meeting essential heat exchange requirements, making it suitable for elevator transportation.

Easy Installation: The installation process is efficient and straightforward. Each unit is factory-tested for performance, with clear labeling for on-site connections to water, electricity, and gas. When used for heating, it can be integrated directly into existing heating water systems without requiring additional auxiliary heat exchange equipment, significantly reducing initial investment costs.

Low Emissions & High Efficiency: The C6 boiler combines full premixed planar combustion with wing pipe heat transfer elements, achieving low emissions (30mg/m³) and high efficiency (106%).

Condensing Low-Pressure Hot Water Boiler H6

Maximum Heating Capacity per Unit: 2.8MW
The H6 series boiler adopts a horizontal structure, integrating full premixed combustion and heat recovery condensing technologies, designed for compactness and ease of installation. It can be operated via a PLC system, facilitating user-friendly control. This model can heat areas up to 40,000 square meters, making it suitable for small and medium hotels, shopping malls, schools, and resorts, providing both heating and hot water effortlessly.

Key Features:

• Full Premixed Planar Combustion Technology: The burner operates automatically when the control panel is activated, with online monitoring of oxygen levels ensuring safe and stable operations while minimizing NOx emissions. The condensate collected at the rear absorbs harmful gases from the flue, effectively reducing pollutants, with NOx levels below 30mg/m³, complying with urban emission standards.

• Exceptional Heat Transfer Efficiency: Utilizing the new Ultraten technology with wing pipes enhances the heat exchange area and optimizes heat utilization, achieving superior energy efficiency.

• Strong Scale Resistance: Water flows externally around the wing pipes, minimizing the likelihood of scaling and facilitating easy cleaning. The large volume design maintains heat exchange efficiency over long-term use while allowing water circulation to cleanse the pipe walls, preventing scaling.

• Compact and Efficient Design: By optimizing the boiler and burner structures, the size is reduced by up to 60% compared to conventional condensing hot water boilers.

Hot Water Boiler D6

Maximum Heating Capacity per Unit: 4.2MW
The D6 boiler is often chosen for use in financial buildings, commercial districts, residential complexes, hospitals, schools, and mid to large-sized hotels due to its ability to provide extensive heating and domestic hot water. Its compact size also conserves space, enhancing its commercial value.

The D6 series employs a dual combination of condensers and deep coolers to achieve deep condensation of flue gas, reducing emissions to 20°C, comparable to outdoor temperatures. This process maximizes latent heat recovery from flue gases, enhancing boiler efficiency. The treated condensate can also be reused for boiler make-up, lowering water consumption. Additionally, as flue gas temperatures decrease, harmful components dissolve into the condensate, directly or indirectly reducing CO2, SO2, and nitrogen oxide emissions, thereby minimizing environmental impact.

High Efficiency and Low Emissions:

• Full premixed planar combustion technology ensures thorough mixing of air and gas for more complete combustion, higher efficiency, and low nitrogen oxide emissions.

• Thoughtful design of heated surfaces optimizes the balance between combustion and heat transfer, enhancing operational efficiency, energy savings, and stability.

• The ultra-high thermal efficiency enables recovery of investment within a year, yielding annual savings of approximately 10,000 cubic meters of gas per ton thereafter.

• Treated condensate can be repurposed for make-up water, minimizing overall water usage and gas consumption.

Low Installation Investment:

• Full premixed planar combustion technology requires a smaller combustion chamber, significantly reducing the boiler's footprint. The use of wing pipes decreases the number of pipes needed for the same heat exchange area, further minimizing boiler size and infrastructure costs.

• Flue gases can be vented using PVC piping, leading to significant cost savings on chimney construction.

Intelligent and Modular Design:

• The intelligent control system offers high levels of automation, user-friendliness, a wealth of features, and flexible control options, displayed on a full-color touchscreen with a multi-window system for clear visibility of operational status.

• Modular capabilities enable multiple boilers to be controlled collectively, allowing intelligent software to adjust the heating load of boiler units for optimal efficiency.

The boilers discussed provide solutions for standard heating and hot water needs. For larger applications, such as those found in airlines, train stations, or large resort hotels, we offer a range of additional products and technical solutions that can accommodate requirements of up to 100MW.
