China Suppliers Factory ZLD Electric Heat Pump Wastewater Treatment Low Temperature Evaporator Machine
Longhope Manufacturing is a leading factory in China specializing in vacuum evaporators and crystallizer systems, backed by over a decade of industry expertise. As trusted suppliers to renowned companies such as HANSWEET and BYD, we focus on high-quality materials including stainless steel (304, 316), duplex steels (2205, 2507), and titanium, all of which are certified with CE and other relevant certifications. Our commitment to excellence makes us a premier choice for businesses seeking reliable and advanced solutions in the field
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
Q1: Which industries benefit from your wastewater treatment solutions?
Our solutions are widely applied across diverse sectors, including oil emulsion treatment, metal cleaning wastewater, printing & dyeing effluent, cutting fluid recycling, electroplating wastewater, as well as the food & beverage and chemical industries.
Q2: How does the Vacuum Evaporation technology save energy?
Our systems operate under low-pressure vacuum conditions (-95 to -97 kPa), which significantly reduces the boiling point of the liquid. This allows the boiling chamber to maintain a lower temperature of 35–37°C, reducing overall energy consumption.
Q3: Does the system require an external feeding pump?
No, the system utilizes a Freon-based compressor system and negative pressure. This enables the automatic suction of raw materials directly into the boiling chamber, eliminating the need for an external feeding pump.
Q4: How does the system handle concentrated liquid discharge?
A forced circulation pump ensures continuous atomization while the liquid level inside the evaporation chamber is auto-regulated. Once your specific concentration targets are met, a built-in device automatically discharges the concentrated liquid.
Q5: Can I request a customized solution for my facility?
Yes. Backed by our professional R&D team, we provide fully customized solutions. To get an accurate quotation, please share your wastewater type, daily treatment capacity, testing data, and desired treatment outcomes with us.
Q6: What makes vacuum evaporators better than traditional evaporation methods?
Traditional evaporation methods are often energy-intensive and difficult to manage. Our low-pressure vacuum evaporators optimize performance, save energy, and feature auto-regulated systems, helping you overcome operational challenges while enhancing productivity and output quality.
