Product Series
Automatic Diesel Gas Boilers
WNS series: Horizontal three-pass fire-tube package boiler, wet-back type, for gas or oil firing. Equipped with modulating burner, PLC touchscreen control, and remote monitoring. Can be installed on a flat base or inside a container, requiring no complex civil work and allowing quick startup.
LHS/LSS series: Vertical fire-tube boiler/water tube boiler, compact footprint, for small factory, hotels, hospitals, and laundries. Start-up in 5–10 minutes; equipped with a steel combustion chamber and a low‑NOx burner. Fully automatic with water shortage and overpressure protection, and front inspection doors for easy servicing.
SZS series: Horizontal D-type two-drum water-tube boiler with welded membrane walls and natural water circulation. Advanced separation system delivers steam humidity below 1%; optional finned economizer and condenser raise efficiency above 98%, while FGR burner keeps NOx under 30 mg/m³.
Economical Coal Wood Biomass Boilers
SZL/SZW series: Horizontal two-drum water-tube boiler with chain grate (SZL) or reciprocating grate (SZW), suitable for biomass fuels with up to 50% moisture and high ash content, plus mixed bulk fuels. Customizable grate types (chain, moving, reciprocating, bubbling bed); reciprocating grate automatically breaks and removes slag, while zoned air supply and oxygen control optimize combustion. Includes two-stage dust removal, optional economizer and air preheater for efficiency over 90%, compact design, steady steam output, and low emissions.
DZL DZH series: Single-drum boiler with combined water-tube and fire-tube heating, available with chain grate (DZL) or manual grate (DZH). Water-cooled side walls and spiral tubes in the drum ensure stable thermal performance, efficiency up to 85%. Optional emission control equipment; easy operation, low maintenance, long service life.
Clean Electric Boilers
WDR series(horizontal): Horizontal electric steam generator, same zero-emission and quiet operation, no fuel system required. High efficiency and precise PID control with multiple safety safeguards. Suited for 0.3-10Ton capacity.
LDR series(vertical): Vertical electric steam generator, zero emissions, silent, no chimney or fuel tank. 99% efficiency with PID touchscreen control and full protection (water shortage, overpressure, short circuit). Instant start, low maintenance, compact footprint for tight spaces.
