Product Description
Gas Vacuum Hot Water Boiler
One machine for multiple purposes: Ingeniously crafted with a unique design and structure, this vacuum boiler offers the versatility of dual hot water outputs. It seamlessly provides dual hot water with varying temperature differentials simultaneously, thanks to its dual-circuit system or independently operable single-circuit system.
High thermal efficiency: The marvel of heat exchange is accomplished through a back-and-forth cycle within a completely enclosed vacuum chamber. Crafted from the finest imported stainless steel, this heat exchanger exhibits extraordinary heat transfer efficiency, yielding remarkable energy savings.
Absolute safety: Operating in a constant state of negative pressure, this boiler eliminates any risk of explosion. Equipped with a suite of safety features, including temperature sensors, safety valves, overheat protection, and vacuum control switches, it comprehensively addresses all potential safety concerns.
Intelligent control: Embrace the future with our advanced digital control and user-friendly LCD screen with a Chinese display. Set temperatures effortlessly, while real-time parameters like furnace temperature and vacuum degree are displayed. Automatically record combustion times and operating faults for hassle-free operation, even without supervision.
Eliminate the trouble of registration procedures: Delivered fully assembled and operating under safe negative pressure, this boiler requires no expansion or explosion oversight. Enjoy exemption from onerous registration procedures, minimizing costs and streamlining installation.
Energy saving: With minimal heat medium water, our boiler harnesses negative pressure steam in the vacuum chamber for ultra-efficient heat exchange. Achieve your desired water temperature swiftly within ten minutes, minimizing preheating losses and maximizing energy savings.
Long life: Crafted from corrosion-resistant stainless steel, the heat exchanger boasts optimal heat transfer and durability. Flange connections simplify maintenance, while the vacuum-enclosed furnace body prevents corrosion and scaling, extending the lifespan of the heated tube bundle.
Insulation structure: Featuring a robust 100mm double-layer insulation, this innovative design significantly reduces external touch temperatures to ambient levels. It ensures heightened safety and dramatically enhances the boiler's thermal efficiency.
Imported low-nitrogen burner: Experience efficient combustion with minimal noise and low exhaust emissions. Our burner adheres to the strictest ecological standards of first-class regions nationwide.
