Product Description
Gas Vacuum Hot Water Boiler
One Machine for Multiple Purposes: Thanks to its innovative design and unique structure, our vacuum boiler excels with dual hot water outputs, allowing it to serve dual water needs simultaneously with varying temperature requirements. Utilize either a dual-circuit system or a single-circuit system, tailored to function independently for unrivaled flexibility.
High Thermal Efficiency: Experience the pinnacle of heat exchange efficiency within a fully enclosed vacuum chamber. Crafted from premium imported stainless steel, our heat exchangers ensure unparalleled heat transfer efficiency, culminating in a profound energy-saving effect that makes a noticeable difference.
Absolute Safety: Our boiler operates in a consistently negative pressure state, virtually eliminating the risk of explosion. Equipped with an array of safeguards-temperature sensors, safety valves, overheat protection, and vacuum control switches-it meticulously addresses all potential safety concerns, offering peace of mind.
Intelligent Control: Our cutting-edge digital control system boasts an LCD screen with a clear Chinese display, offering advanced operational capabilities. Adjust the temperature freely while monitoring furnace temperature, vacuum levels, and other parameters in real-time. The system records combustion time and operating faults automatically, simplifying operation to the point of automated, hands-free functionality.
Hassle-Free Registration: Shipped fully assembled and functioning under negative pressure, our boiler alleviates expansion or explosion risks, thus exempting you from cumbersome supervision and inspection. During installation, bypass complex registration procedures, significantly cutting down on costs and administrative burdens.
Energy Saving: With only a minimal volume of heat medium water, the boiler's heat exchange occurs in a vacuum chamber complemented by negative pressure steam. This configuration achieves remarkable efficiency, delivering warm water at the desired temperature within just ten minutes, devoid of preheating losses, ensuring an impressive energy-saving impact.
Long Life: Constructed with superior heat transfer stainless steel, our heat exchanger promises rapid heat conduction and exceptional corrosion resistance. Flange connections at pipe ends guarantee ease of maintenance and replacement. Operating in a vacuum state, the furnace body remains free from corrosion or scaling, and the heated tube bundle stays untouched by flame or flue gas, thereby substantially prolonging the service life.
Insulation Structure: Featuring a robust 100mm double-layer insulation structure, the boiler's exterior touch temperature is minimized to ambient room temperature. This enhancement not only fortifies safety but also significantly elevates the boiler's thermal efficiency.
Imported Low-Nitrogen Burner: Our burner is designed for high-efficiency combustion with minimal noise and reduced exhaust emissions, perfectly aligning with the national standards for first-class environmental areas.
