AQUAMAX
Wood & Biomass Briquette Hot Water Boiler
The AQUAMAX is a robust, fully Wet-Back, Three-Pass smoke tube hot water boiler designed for maximum thermal recovery using cost-effective solid fuels. Engineered for durability and high performance, the AQUAMAX is the ideal solution for industries looking to utilize wood logs or biomass briquettes to generate consistent hot water.
Operating Range
- Capacity – 4 lac Kcal/Hr. to 20 lac Kcal/Hr.
- Fuel- Wood Log, Biomass Briquette
- Temperature- up-to 90℃ and special design up-to 160℃
Advanced Engineering for Solid Fuels
The AQUAMAX features a horizontal plain furnace extending along its entire length, providing ample combustion volume for solid fuels.
- Three-Pass Smoke Tube Design: Flue gases travel through three distinct passes, ensuring that maximum heat is transferred to the water before the gases exit.
- Fully Wet-Back Construction: Unlike "Dry-Back" boilers, the rear combustion chamber is completely surrounded by water. This eliminates the need for bulky, expensive rear-end refractory, prevents heat loss, and significantly reduces maintenance costs.
- Superior Access: The large rear door provides total access to the furnace and smoke tubes, making cleaning and tube inspection straightforward and reducing operational downtime.
Key Features & Benefits
- Fuel Versatility: Highly efficient when fired with Wood Logs or Biomass Briquettes, allowing you to choose the most economical local fuel source.
- Robust Thermal Design: Tube sheets at both ends securely hold the flue tubes, ensuring a leak-proof and durable structure capable of handling thermal expansion.
- Automated Safety: Equipped with advanced instrumentation to monitor water temperature and flow, ensuring safe and reliable operation 24/7.
- High-Temperature Options: While standard models operate up to 90°C, specialized custom designs are available for pressurized requirements up to 160°C.
Targeted Industry Applications
The AQUAMAX is a versatile workhorse used extensively in sectors that require large volumes of hot water at a low operational cost:
- Textile Industry: For dyeing, washing, and fabric finishing processes.
- Food & Beverage: For pasteurization, cleaning, and processing applications.
- Hotels & Hospitality: For central heating, laundry, and large-scale hot water systems.
- Chemical & Pharmaceutical: For jacketed vessel heating and process requirements.
- Plywood & Timber: For log conditioning and resin curing.

Frequently Asked Questions (FAQ) about Wood & Biomass Briquette Hot Water Boiler
In a wet-back design, the rear combustion chamber is submerged in water. This prevents the rear wall from overheating and eliminates the need for frequent refractory repairs, which are common in dry-back boilers. It also increases the overall heating surface area for better efficiency.
Yes. The AQUAMAX furnace is designed to handle various solid biomass fuels. This flexibility allows you to switch fuels based on seasonal availability or market pricing without needing significant hardware changes.
Solid fuels produce a lot of heat energy. The three-pass design ensures the hot gases stay inside the boiler longer, traveling through the tubes three times. This allows the water to absorb as much heat as possible, leading to lower fuel consumption and lower exhaust temperatures.
Because biomass and wood produce ash, regular cleaning is necessary to maintain efficiency. However, the AQUAMAX is designed with a large, easy-to-open rear door that gives maintenance teams full access to the tubes, making the cleaning process fast and simple.
Yes. Solid fuel boilers require a chimney (stack) to safely vent combustion gases and provide the necessary draft for the furnace. We can provide guidance on the appropriate chimney height and diameter for your specific installation.
