Product Description

Product Description

One machine for multiple purposes: Experience the innovative design and flexible functionality of our vacuum boiler, engineered with a dual-circuit system to deliver two distinct hot water outputs simultaneously. Whether you prefer a dual-circuit or single-circuit operation, this machine offers independent use for versatile hot water demands.
High thermal efficiency: Our heat exchanger operates within a fully enclosed vacuum chamber, utilizing premium imported stainless steel for exceptional heat transfer. This results in remarkable thermal efficiency and outstanding energy savings, ensuring you get the most from your energy usage.
Absolute safety: Safety is paramount with our boiler, operating under constant negative pressure to eliminate explosion risks. Equipped with advanced temperature sensors, safety valves, and overheat protection, it comprehensively addresses all potential hazards, ensuring peace of mind.

Intelligent control: Enjoy cutting-edge digital control with an intuitive LCD screen displaying in Chinese. Easily adjustable temperature settings, real-time display of furnace conditions, and automatic fault recording make operation straightforward and user-friendly, promoting effortless, unattended management.
Eliminate the trouble of registration procedures: Our boiler arrives ready for operation without the need for complex registration, thanks to its negative pressure operation and explosion-impervious design. This not only saves time but also reduces installation costs significantly, bypassing functional department requirements.

Energy saving: Maximize efficiency with our compact heat medium, utilizing negative pressure steam within the vacuum chamber for rapid water heating to desired temperatures in mere minutes. This process minimizes preheating losses and amplifies energy conservation benefits.
Long life: Crafted from corrosion-resistant stainless steel, our heat exchanger promises swift heat transfer and durability. With flanged connections for easy maintenance and a vacuumed furnace body preventing corrosion, the system boasts an extended service life.
Insulation structure: Enhance safety and thermal efficiency with our advanced 100mm double-layer insulation, which maintains the exterior touch temperature at room level, offering peace of mind and optimizing energy retention.
Imported low-nitrogen burner: Our burners deliver high-efficiency combustion with minimal noise and emissions, meeting national first-class area standards, ensuring eco-friendly operation.
