Multi-effect evaporator or MVR evaporator is particularly suitable for the distillation, concentration and drying of heat-sensitive materials under vacuum conditions. By lowering the boiling point of the liquid, it can reduce energy consumption while ensuring the quality of the product.

Organic solvents are widely used in industries such as paints, pharmaceuticals, dyeing, and textiles. Due to environmental protection and production cost considerations, they need to be recycled and reused. The Roets water ring vacuum unit can effectively recover them, achieving a recovery rate of over 95%. The ultimate vacuum level can reach 0.5 Pa(A), and the air extraction volume can reach 10,000 cubic meters per hour.

The dehydration of materials or reactants can be achieved by using drum or belt filter units in conjunction with vacuum pumps, or by employing water ring compressors for pressurized dehydration.

The transportation of powder-like materials is achieved by using a vacuum pump to obtain the air source. This not only ensures that the materials are not affected by the environment in the sealed pipeline, but also prevents any pollution to the environment.
