With over a decade of experience, we have established ourselves as a trusted supplier to renowned companies like HANSWEET and BYD. Our expertise includes working with top-grade materials such as stainless steel (304, 316), duplex steels (2205, 2507), and titanium, all certified with CE and other industry-recognized certifications. Choose Longhope Manufacturing for reliable solutions that meet your industrial needs

    Our solutions are applied across diverse industries: oil emulsion treatment, metal cleaning wastewater, printing & dyeing effluent, cutting fluid recycling, electroplating wastewater, and more. The technology operates on two core principles:
    1. Vacuum Evaporation Principle
    Lower pressure reduces the boiling point. Under vacuum conditions (-95 to -97 kPa), the boiling chamber maintains a temperature of 35–37°C. This negative pressure enables automatic suction of raw materials into the chamber.
    2. Compressor System Principle
    A Freon-based compressor system facilitates heating and cooling. Notably, the system eliminates the need for a feeding pump—materials are drawn into the boiling chamber, transferred to a heat exchanger, and water is evaporated. A forced circulation pump ensures continuous atomization, while the evaporation chamber’s liquid level is auto-regulated. Once concentration targets are met, a built-in device discharges the concentrated liquid.
    Backed by a professional R&D team, we deliver fully customized solutions to meet unique client needs and support business growth. Committed to excellence in quality, pricing, and delivery, we invite you to share details about your wastewater type, daily treatment capacity, testing data, and desired outcomes. This information will enable us to provide an accurate quotation and tailor a solution specifically for your requirements.

    Frequently Asked Questions
    What industries can benefit from your wastewater treatment solutions?
    Our solutions are applied across diverse industries, including oil emulsion treatment, metal cleaning wastewater, printing & dyeing effluent, cutting fluid recycling, electroplating wastewater, food & beverage, and chemicals.
    How does the Vacuum Evaporation Principle work?
    By operating under negative pressure (-95 to -97 kPa), the boiling point is reduced, allowing the boiling chamber to maintain a temperature of 35–37°C. This negative pressure also enables the automatic suction of raw materials into the chamber.
    What are the benefits of the Compressor System Principle in your evaporators?
    The Freon-based compressor system facilitates heating and cooling without needing a feeding pump. Materials are drawn into the chamber, water is evaporated, and a forced circulation pump ensures continuous atomization while liquid levels are auto-regulated. The concentrated liquid is then automatically discharged.
