Electric Heat-Pump Vacuum Evaporator for Wastewater.

The Vacuum Heat Pump Evaporator delivers up to 90% energy savings and ultra-low temperature vacuum evaporation (down to 32°C at 45 mbar) to protect heat-sensitive wastewater streams while cutting operating and cooling-water costs. Its compact, modular skid or cabinet-style build, German core components assembled in China, corrosion-resistant materials and fully automatic controls provide reliable, low‑maintenance performance and fast installation for small-to-medium plants. Shipped in standard export cartons and factory-tested for quality, this space-saving, high-quality system simplifies procurement and rapid deployment for wastewater treatment and industrial concentration needs.

The Vacuum Heat Pump Evaporator uses heat-pump compression and high vacuum to evaporate and condense wastewater at ultra-low temperatures, enabling efficient evaporation, crystallization and drying of heat-sensitive materials. Its modular, compact structure with imported core components assembled domestically provides fully automatic, low‑maintenance operation with minimal cooling water needs and a low failure rate. Running solely on electricity and cutting energy consumption by up to 90%, it offers a cost‑effective, environmentally friendly wastewater treatment solution ideal for space‑constrained small and medium enterprises.

The Vacuum Heat Pump Evaporator is an electric, modular system that uses heat-pump compression and high vacuum (down to 45 mbar, enabling evaporation around 32°C) to concentrate wastewater and treat heat-sensitive materials with minimal corrosion. By recovering condensation heat and eliminating the need for steam, it can cut energy consumption by up to 90%, reduce cooling water use, and simplify supporting equipment compared with traditional and MVR systems. Fully automated and assembled with German core components in China, the compact unit is optimized for small-to-medium plants (under 1000 kg/h) for fast installation, low maintenance, and environmentally friendly operation.

Efficient Compact Sustainable Recovery

Built after years of R&D and strict quality control, the Vacuum Heat Pump Evaporator combines an electric heat-pump core with vacuum operation to create a compact, durable system designed for efficient industrial wastewater concentration and resource recovery. It quickly concentrates wastewater and reclaims clean water and salts by lowering boiling points under vacuum while the heat pump recovers thermal energy, delivering high recovery rates with low power consumption and minimal scaling. Key features and advantages include a modular footprint, automated PLC control, corrosion-resistant materials, low maintenance and noise, compliance with zero-liquid-discharge goals, and significant reduction in disposal costs.

The Vacuum Heat Pump Evaporator is constructed from corrosion‑resistant stainless steels and engineered alloys for all wetted parts, with hygienic finishes where required for pharmaceutical and food industries. Key components such as evaporator shells, condensers and vacuum chambers use high‑grade 316L or duplex stainless steel, while compressors, refrigerant piping and seals employ refrigerant‑compatible metals and durable elastomers designed for low‑temperature, high‑vacuum operation. Modular assemblies combine factory‑tested German core components with protective coatings and replaceable wear parts to ensure long service life, easy maintenance and chemical compatibility with aggressive wastewater streams.
