Premium 2.8 MW Vacuum Boiler by Chinese Boiler Manufacturer

We’re a China‑based boiler maker with over 30 years’ experience, and our latest 2.8 MW vacuum hot‑water boiler is built especially for hospitals, office blocks, hotels and similar large venues.Thanks to our self‑developed winged‑tube design—delivering five times the heat‑transfer efficiency of standard smooth tubes—the furnace volume is greatly reduced, yielding a 40 % smaller footprint, all while providing fully automated controls for effortless, reliable heating.

Key Benefits for Vacuum Boiler

1. Exceptional Energy Efficiency

• Our boiler runs under negative pressure to push thermal efficiency past 98 %—well above what you’d see in a standard heating system.

• Its advanced low‑NOₓ burner keeps emissions down to around 20 mg/m³, comfortably meeting the toughest environmental rules.

• And because we’ve optimized both the combustion process and the way flue gases give up their heat, you’ll see real savings on fuel bills and day‑to‑day operating costs.

2. Compact Footprint & Flexibility

• T6 Vacuum Boiler, featuring our space‑saving winged‑tube heat exchangers, enables installation in basements, rooftops or other confined boiler rooms—ideal for hotels, hospitals and other space‑restricted facilities.

• Multiple T6 vacuum boilers can be connected in parallel to easily increase capacity to handle peak hot water loads.

3. Safety & Reliability

• Operates under vacuum (negative pressure), eliminating risk of explosions or ruptures—even under adverse conditions.

• High‑quality stainless steel heat exchanger avoids scaling and corrosion, extending service life by 2‑3× compared to conventional models.

• Products operating under negative pressure are often exempt from regulatory inspections, simplifying compliance and maintenance.

4. Smart & User‑Friendly Operation

• Fully automated control system supports remote monitoring, mobile control, auto-diagnostic fault detection, and safety alarms.

• Seamless temperature regulation adapts to changing external conditions, ensuring stable heating comfort and energy savings.

5. Proven Reliability in Institutional Projects

• Our T6 vacuum hot water boilers have been widely adopted in hospitals (for sterilization & heating), office complexes, hotels, swimming pools, and campuses.

• As a seasoned boiler manufacturer since 1998, we have completed over 150,000 installations spanning 80+ countries, adhering to ISO9001, ISO14001 and other certifications.

Frequently Asked Questions (FAQ)

Why choose a vacuum boiler instead of a conventional heating boiler?

Vacuum boilers work under negative pressure—this removes explosion risk, reduces corrosion and scaling, and achieves efficiency above 98 %. Ideal for critical applications like hospitals and hotels.

Can the 2.8 MW unit handle a building’s entire heating demand?

Yes. For large hotels or complexes, multiple 2.8 MW units can run in parallel for both redundancy and scalable capacity.

How small is its required footprint?

Our design enables installation in compact boiler rooms—such as rooftops or basements—with significantly smaller space requirements compared to traditional heating boilers.

What safety and compliance certifications does it hold?

Our boilers meet ISO9001, ISO14001, OHSAS standards; negative‑pressure vacuum models often qualify for regulatory inspection exemptions in applicable regions.

What about smart control and maintenance?

Full digital control includes real‑time monitoring via mobile app, alarm warnings (pressure, flame, flow, temperature), and auto‑fault diagnosis—ensuring smooth unattended operation.

What after‑sales service do you offer?

We provide full support: engineering guidance for installation, commissioning, operator training, warranty support, local spare parts, and optional overseas support.
