Overview of AGT Vapor Compression Still

Vapour compression distillation is a high efficiency method to produce water for injection (WFI), the WFI produced by AGT vapor compression distillation system can meets the most strict pharmaceutical standard and in accordance with all recognized pharmacopoeias.

The produced water quality is excellent, with a conductivity of
The WFI generation system features a five-stage preheating process, effectively utilizing the residual heat.
All heat-exchangers are designed with a dual-tube plate structure, with the inner tube plate expanded and the outer tube plate welded, meeting cGMP and FDA standards.
Materials in contact with purified water, secondary steam, and injection water are made of 316L stainless steel, with a surface roughness of Ra ≤ 0.4 μm.
Non-pressure vessels ensure high safety, making operation and maintenance easier.
Compared to multi-effect distillation, this vapor-compression WFI still operates at lower evaporation temperatures, leading to a longer lifespan and reduced risk of red rust formation.
Siemens PLC automation control allows for one-touch start/stop, with strict interlocking controls and automatic detection of system anomalies.
Real-time energy monitoring modules and cloud services are available for remote monitoring, control, and diagnostic support.

State-of-the-art Maglev Vapor Compression Technology

Maglev (Magnetic levitation) is a cutting-edge bearing technology that has been widly used in air compressor and other rotating equipment fields, AGT and it's subsidiary Leheng develped the maglev steam compressor together according to the pharmaceuiticle guidlines. Mechanical vapor compression (MVC) has been widly used in various applications like MVR evaporator, heat pump assisted distillation. The maglev steam compressor featuring friction free, oil free, and cooling water free, that means the compressor has higher effeciency and lower consumption.

Vapor Compression Distillation Process

WFI generation process

Preheating System

The distiller employs a 5-stage pre-heating system, which can maximizing the use of residual heat within the system, and ensuring no high-temperature water is produced. Pharma grade double tube sheet design shell & tube heat exchanger reduces the risk of leakage.

Evaporation System

The evaporator features a vertical rising film design. The water in the shell side of the evaporation chamber can be fully drained, guaranteeing the reliability of the water quality.

MVR Steam Compression System

The system uses a compressor to compress secondary steam, increasing its temperature and pressure to supply heat for the subsequent evaporation of purified water. This process significantly reduces energy consumption. Two compressor types are available—magnetic levitation and high-speed direct drive—ensuring efficient and energy-saving performance across all models.

Water Discharge

Condensed and qualified WFI enters to a buffer tank before being pumped to a WFI storage tank. Non-qualified water will be discharged appropriately.
