Introduction
The LSS series is a vertical water-tube steam generator, capacity 50–2000 kg/h. It fires natural gas, diesel, LPG, heavy oil, or dual-fuel. The Italian modulating burner gives stable combustion.
Start-up takes only 5–10 minutes. Automatic protection against water shortage and over pressure. Front doors for easy maintenance. Small footprint – fits basements, roofs, or tight spaces. Ideal for small factories, hotels, hospitals, and laundries.
●Food processing (cooking, sterilization, drying)
●Textile & garment (ironing, dyeing, heating)
●Hospital & healthcare (sterilization, laundry)
●Hotel & hospitality (kitchen steam, heating, laundry)
●Small manufacturing (rubber, chemical, paper, textile, pharm, etc.)
●Building heating (basement, roof, or floor installation)
Its ability to be installed in narrow spaces – such as basements, between floors, or on rooftops – makes it a versatile choice for urban or space‑constrained projects.
1. Compact Space‑Saving Design
Vertical top‑fired layout requires minimal floor area. Can be placed in tight locations.
2. Quick Steam Generation
Specially designed drum and large water capacity, the boiler reaches full load in only 6~8 minutes from cold start. Stable steam output is maintained.
3. High Thermal Efficiency
Thermal efficiency reaches up to 90% (with economizer), reducing fuel consumption and operating costs.
4. Fully Automatic & 100% Safe
Equipped with automatic ignition, flame monitoring, water level control, and over‑pressure safety valves. Low failure rate and easy maintenance ensure long‑term reliability.
5. Self‑Contained & Easy Installation
Delivered as a complete, pre‑tested unit. Low vibration, low noise, and no need for a heavy concrete foundation – you can position it flexibly and start operation quickly.
6. Customized Solutions
We offer a range of voltage and steam capacity tailored to client requirements, with solutions available in both platform-mounted and containerized steam boiler system configurations.
In addition to LSS steam generators, we also offer fire-tube steam generators, biomass pellet steam generators, electric steam generators, clean pure steam generators, and coal-fired steam generators. Please feel free to contact us at any time.
