Core Principles of Technology

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.

Frequently Asked Questions

What materials are used in Longhope's vacuum evaporators?

We specialize in manufacturing equipment using high-quality materials including stainless steel (304, 316), duplex steels (2205, 2507), and titanium material. All our systems are certified with CE and other standard certifications.

What types of wastewater can these systems treat?

Our solutions are designed for diverse industrial applications, including oil emulsion treatment, metal cleaning wastewater, printing & dyeing effluent, cutting fluid recycling, and electroplating wastewater.

How does the vacuum evaporation principle work?

By lowering the pressure within the system (-95 to -97 kPa), the boiling point of the liquid is reduced, allowing the boiling chamber to operate at a low temperature of 35–37°C. The negative pressure also enables automatic suction of raw materials.

Does the compressor system require a feeding pump?

No, our compressor system eliminates the need for an external feeding pump. Negative pressure automatically draws materials into the boiling chamber.

How does the system manage continuous concentration and discharge?

A forced circulation pump ensures continuous atomization, while the evaporation chamber’s liquid level is automatically regulated. Once the concentration targets are met, a built-in device automatically discharges the concentrated liquid.
