Available in fire-tube, water-tube, biomass, coal, and electric versions. Certifications: ASME, CE, ISO, EAC, DOSH.

WNS Series – Horizontal Fire Tube

1. Fully automatic, safe, and high-efficiency gas/oil boiler.
2. Horizontal, three-pass, fire-tube design for quick installation (package boiler).
3. Wet-back configuration for high-temperature resistance and improved airtightness.
4. Internationally branded burners (Weishaupt, Baltur) with electronic modulation.
5. Large-size corrugated furnace lining + patented threaded flue pipe design.
6. Equipped with an energy-saving device; thermal efficiency reaches 98%.
7. PLC control with touchscreen, remote monitoring, and safety alarms.
8. Can be installed on a platform or inside a container, requiring no complicated installation and allowing for quick commissioning.

LHS Series – Vertical Steam Generator

1. Vertical fire-tube boiler, requires very little floor space.
2. Ideal for small industries, hotels, hospitals, laundries, and processes with moderate steam demand.
3. Fast start-up (5-10 minutes to reach working pressure).
4. Robust construction with a high-strength steel combustion chamber.
5. Quiet operation and low emissions thanks to low NOx burners.
6. Fully automatic, includes a protection system against water shortage and overpressure.
7. Easy maintenance thanks to its front inspection doors.

SZS Series – D-type Water Tube

1. Two-drum water-tube boiler, vertical D-type configuration.
2. Fully welded membrane walls for maximum leak tightness and safety.
3. Ideal for high steam demands in continuous industrial processes (chemical, paper, cogeneration).
4. High steam quality (humidity <1%) thanks to its advanced separation system.
5. Large heating surface and natural water circulation, eliminating the need for a circulation pump.
6. Thermal efficiency exceeding 98% with an optional finned economizer and condenser.
7. Very low NOx emissions (≤30 mg/m³ with FGR technology).
8. Packaged or semi-packaged design for quick on-site installation.

DZL / DZH Series – Coal, Firewood, Biomass

1. Single-drum boiler, combining water-tube and fire-tube heating.
2. Combustion equipment: chain grate (DZL) or manual chain grate (DZH).
3. Radiation zone design with water-tubes in the side walls.
4. Convection zone with two tube wings and spiral smoke tubes in the steam drum.
5. Symmetrical distribution of the upper drum, water walls, and headers, ensuring thermal stability.
6. High efficiency (up to 85%) and optimized heating surface layout.
7. Environmental protection measures available: baghouse dust collector, double-tower desulfurization, etc.
8. Easy operation, low maintenance costs, and long service life.

SZL / SZW Series – Watertube Biomass Coal

1. Horizontal, two-drum water-tube boiler with chain grate (SZL) or reciprocating grate (SZW).
2. Adapted for burning biomass fuels with high moisture content (up to 50%) and high ash content, as well as mixed bulk fuels.
3. Custom-designed for different fuel types, allowing for various combustion configurations (chain grate, moving grate, reciprocating grate, bubble bed grate).
4. Compact structure, high-quality steam, and abundant production.
5. The reciprocating grate (SZW) automatically breaks down slag and removes ash, preventing blockages.
6. Zoned air distribution and real-time oxygen control for maximum combustion efficiency.
7. Two-stage dust removal system for low emissions.
8. Economizer and air preheater options for increased thermal efficiency (>90%).

WDR/LDR Series – Electric Steam Generator

1. Electric steam generator with zero emissions and no combustion.
2. Completely silent operation without the need for a chimney or fuel tank.
3. High efficiency (99%): almost all electrical energy is converted into heat.
4. Precise temperature and pressure control via PID and touchscreen.
5. Vertical (LDR) or horizontal (WDR) design depending on available space.
6. Multiple protection levels: water shortage, overpressure, and short circuit.
7. Instant start and minimal maintenance (no burners or fuel system).
