Choose Longhope Manufacturing for top-tier solutions that leverage our extensive experience and commitment to quality
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.
Our evaporators work under low-pressure conditions to reduce boiling points, saving energy while ensuring optimal performance. Ideal for industries like metal industry, food & beverage, and chemicals. Say goodbye to traditional evaporation challenges and hello to enhanced productivity and quality.

Frequently Asked Questions
Q:
Which industries can apply your wastewater treatment solutions?
Our solutions are widely applied across diverse industries, including oil emulsion treatment, metal cleaning wastewater, printing & dyeing effluent, cutting fluid recycling, electroplating wastewater, the metal industry, food & beverage, and chemicals.
Q:
How does the Vacuum Evaporation Principle work?
The system operates under vacuum conditions (-95 to -97 kPa), which lowers the boiling point of the liquid. This allows the boiling chamber to maintain a low temperature of 35–37°C and enables the automatic suction of raw materials into the chamber.
Q:
Does the compressor system require a feeding pump?
No, the system eliminates the need for a feeding pump. Materials are drawn directly into the boiling chamber by negative pressure, transferred to a heat exchanger, and the water is then evaporated.
Q:
How is the concentration level regulated and discharged?
A forced circulation pump ensures continuous atomization while the liquid level is auto-regulated. Once the preset concentration targets are met, a built-in device automatically discharges the concentrated liquid.
Q:
What details should I provide to get a customized solution and quotation?
To provide an accurate quotation, please share details about your wastewater type, daily treatment capacity requirements, testing data, and your desired treatment outcomes.
Q:
What are the main benefits of using your vacuum evaporators?
By working under low-pressure conditions to reduce boiling points, our evaporators save energy while ensuring optimal performance. They help overcome traditional evaporation challenges, enhancing productivity and quality.
